Will there be a SC equivalent to Diver Propulsion Vehicles?

In particular I think it could be cool to have a Drill on the front end of a DPV, allowing a player to drill into the side of a large ship, and get inside to fight the crew in FPS. Maybe some models would have upgraded stealth tech, other models will carry 2-4 people in a very cramped manner.

Subnautica - Pushing Boundaries and Facing Fears

Let's talk about fear. Minor mechanics-based Subnautica spoilers follow.

What Had Happened

Last night, Subnautica evoked the single most intense emotional response I've had to a game. Let me set the scene.

Twilight was falling, and the water was beginning to get dark. Visibility was already poor in the red water, but I felt relatively safe. After all, I had my one-man submersible, with its bright headlights and zippy movement.

I felt safe.

Beneath me, I saw a piece of debris with shiny new technology. So, of course, I hopped out of my submarine and pulled out my trusty scanner, pointing my submersible's lights towards the technology. First mistake.

Swimming down, I was about 20 meters from my sub, ready to scan whatever the new technology would have been. 20 meters. Second mistake.

Right before I reach the technology, an unearthly ROAR comes out of my speakers alongside the "you are so fucking dead music", and I turn, just as a >!Reaper Leviathan!< about 30x my size snaps my sub in its jaws, throw my light source and my heart into disarray. I scream FUCK before beginning to mutter the same thing over and over again as I leave my sub for lost, pulling out my handheld Diver's Propulsion Vehicle and praying praying praying that it chooses the sub over me.

Fear.

For the next 15 or so minutes, I sat in my base. And then went out into the shallows. but never so far that I couldn't see my base. Thinking back, I can feel my mind recreating last night's feeling and my adrenaline still spikes recounting this.

The Aftermath

Now, I think it's probably clear from that story that I'm not a horror guy. I don't watch horror movies, I avoid games like Soma and RE7 like the plague. Subautica, though...the bright colors and beautiful atmosphere made it feel approachable, and safe. How wrong I was. And I'm so thankful I was wrong.

If I'd never tried Subnautica, I never would have felt this emotion so viscerally. I never would have been willing to explore it - I would have remained afraid of fear itself continually. And, honestly, I never would have experienced the thrill of seeing a >!Reaper!< up close - and surviving.

So, to all you patient gamers out there like me, I have a recommendation: give Subnautica a try. The experience is something incredible, and you might end up learning something about yourself in the process.

(That having been said, I think once I finish Subnautica, I may need a while before I hit up Below Zero...)

The Disappearance of Scuba Diver, Ben McDaniel, Part 4(A): Bens Gear

On August 18th 2010, Ben McDaniel, a 30 year old scuba diver, vanished 115ft under water from the cave at Vortex Spring diving resort, in Ponce De Leon, FL. Ben was last seen by two Vortex Spring (VS) employees, Eduardo Taran and Chuck Cronin, around 7:30pm at the gate blocking untrained and non-certified divers from entering the most dangerous parts of the cave. Ben did not have the certification and training required to rent the gate’s key from the dive shop, though he was suspected of tampering with the gate and breaking into the gated area after hours. Fearing Ben would have an accident getting tangled up or over exert himself trying to force his way through the gate, Eduardo decided it would be safer to unlock the gate for the determined diver. That was the last time anyone saw Ben. Recovery divers exhaustively and painstakingly searched every nook and cranny of the deepest, most dangerous areas of the cave. A world-renowned cave diver went as far back into the cave as humanly possible- further than anyone else had ever gone, but found absolutely no evidence of Ben ever being back there. The diver explained to Ben's terrified family that at 6’1" and 210-220lbs, Ben could not have physically gone any further into the cave- that it was spatially impossible for Ben and his gear to even fit through the dangerous 4th restriction, let alone the final fissure at the β€œEnd of the Line”. If Ben, in some ludicrous superhuman feat, managed to squeeze his large frame and 200+lbs of gear into the crack just 4 to 6 inches tall, far enough to not be visible, no diver would ever be able to follow. Divers began to wonder if Ben was ever even in the furthest reaches of the cave. If he isn't in the cave, where could he be? Maybe it was a hoax. Maybe he's not even dead…


Hello all, welcome to part 4(A) of a comprehensive, multi-part series about the disappearance Ben McDaniel. Part 4 was getting too long for reddit’s character limits, but not long enough for two different parts, I've decided to make two posts, labeled Part 4(A) and Part 4(B).

RoE Season 6 predictions.

With RoE season 6 right around the corner, the Devs has made subtle teases about features being added next week. They've released photos of the new battle boats and teased messages seemingly about building cover and holograms.

-Can't hit your enemies? Hit your teammates! -No cover? No problem. -Outnumbered? Use an illusion.

Recently, they've updated their twitter banner which shows icons of equipment which seem to relate to these messages. Bare in mind this is all speculation but I think the details are adding up.

https://preview.redd.it/b2nsw9q2s6t31.jpg?width=1500&format=pjpg&auto=webp&s=5e49ecfa26720b465922d54859ba6752bce2ca03

From left to right; 1.) Deployable shield 2.) DPV (diver propulsion vehicle) 3.) Drone 4.) Hologram 5.) Med-Gun? 6.) Repair tool (vehicle upgrade kit?)

It seems item #2 looks very much like a top-down view of the DPV. Since it's already part of every class, I can only guess that it has something to do with the other equipment.

I predict that these items will be selectable equipment to go along with your existing traversal loadout. I doubt they will be loot drops throughout the match considering how much equipment you can already pick up, but I could be wrong. This could make great opportunities for team play! I can already imagine teammates picking roles like a scout or a medic or even an organized team setting up a road block.

With that in mind, considering battle boats are confirmed, I doubt Mt. Dione will relaunch with season 6. But I am hopeful. During an interview at gamescom, a representative said Mt. Dione was getting revamped and promotional art would be shared eventually. I hope it'll be available later season 6 or the next, just in time for Christmas season!

Is the DPV broken?

The Diver Propulsion Vehicle they introduced recently is still an enigma to me. I mean, I know how to use it, and I know how to shoot the gun in the DPV, but it seems that every bullet takes about 1hp from the opponent and every time I get shot, half my life goes away. Once, in a Duo game, me and my partner shot a guy 10 times each, and he still managed to survive. But then, another duo appeared, and 3 or 4 shots after we were both dead. I mean, how can this be so unbalanced? Do I have to unlock something to enable real damage on the DPV? Feels so frustrating playing this game, hitting so many shots and get zero kills, and die to only 2 or 3 shots.

Science AMA Series: I’m Elliott Jessup, Head of Scientific Diving at the California Academy of Sciences. Using advanced diving technology, I lead scientists to some of the least-explored areas of the oceanβ€”deep coral reefs between 200 and 500 feet. AMA!

Hi Reddit,

I split most of my time between training scientists how to dive, organizing expeditions, and wrangling the scientists actually on those expeditions (read: herding cats). My main focus is coral-reef exploration, especially this incredible sweet-spot between 200 and 500 feet called β€œthe twilight zone," more officially/specifically referred to as mesophotic coral ecosystems. While I’ve become a scientist through osmosis, my expertise is really in the technology and training required to make scientific exploration happen. That means I spend a lot of time playing with fancy high-tech tools such as mixed-gas closed circuit rebreathers and diver propulsion vehicles, and spend a lot more time doing decompression than actual exploration. I eat bananas underwater, have dreams of a roving research vessel, and am committed to advancing scientific exploration.

Some recent press on our twilight-zone team via Gizmodo and Scientific American, plus some extra underwater expedition and banana-eating footage here: https://vimeo.com/elliottjessup. I'm also on Twitter @scidiving

UPDATE: Thanks for all the questions, be back at 2pm PST to answer more questions, faster. (Had to start off slow due to scheduling, thanks for your patience!)

**UPDATE: Thanks again Reddit! I have to sign off for now, I'll try to sign on tomorrow to answer some more questions if my flight has wifi!

HUGE Update coming to ROE Garena on 4/24

Source (gamer.com.tw is Garena's official forum for those wondering)

Video preview from BryaaNz

Its basically most of the stuff previewed in the most recent Face-to-Face. While they have stated a date for the patch for the Garena client, generally they receive patches a week later than the Steam client. While it could come sooner for Steam, its still possible Garena will be ahead of patches yet again seeing as we don't have upcoming patch notes yet.

Updates included in the "second stage" of Season 3:

β€’ Flintlock update and change to the pirate ship mechanic. Instead of "riding" the boat like before, you and other players can be on the boat and fight other players over the onboard treasure chest. Video

β€’ 3D Map selection

β€’ Underwater treasure hunt, which will be part of the main modes (as confirmed in BryaaNz's video). Article showcases a new gadget ( Diver Propulsion Vehicle ) to be included in ALL combat packs. It includes an built-in weapon (possibly SMG class) with 500 rounds which cannot be refilled or reloaded. The DPV (and the weapon) can be used under and below water. 1 2 Video

β€’ Final art for the new weapons to be included: P90 & Skorpion

β€’ New helmet/armor tier surpassing 'Superior' ones, no official name yet. Let's call it Ultimate Armor/Helmet for now. Currently found in Treasure Chests. Screenshot / Video

β€’ Healing while above or below water. Video

While they have not stated the other stuff mentioned in the recent Face-to-Face (move to DX12 and Vehicle Suspension updates), its still possible it could come but don't hold your breath just yet.

EDIT: Updated with more concrete info from u/BryaaN13's video. And no, DX12 wasn't included in the test client, but it could still come since the new SMGs and 3D map selection weren't in the test client as well.

So people want Hijacked out in all that wasted space in the water?

How about scuba gear all along the beach and a sunken Hijacked map? Maybe that and at least one other new boat that can swap locations and either or both can be sunken or afloat?

All I know is anytime I dropped into the staging area in the water, I swam as far as I could and found nothing. I liked the "emptiness" of the desert/turbine/rocky area, but the water was basically unused space.

With or without Hijacked, let's get some scuba gear and maybe some diver propulsion vehicles and somewhere to use them.

As a novice diver which 'speciality courses should I avoid ?

Hey everyone how's it going I am a novice diver with only open water, advanced open water and side mount courses under my belt and only a few diver like not even double digits. Being the dumb gullible novice I was I was sucked into a sales pitch and bought $5000 aud worth of hollis side mount gear (sms75) but since my buoyancy is still bad I feel like a tool now since I'm using tech diver gear but keep crashing into everything. Anyway I want to avoid this kind of mistake in the future and want to know what courses to avoid(I've heard boat diver or underwater photography are useless courses) ? My goal is to stay in the recreational limits, dive exotic nice locations and take pretty pictures and that's it. The speciality courses that interest me are deep diver, nitrox, rescue diver, wreck, search and recovery and dry suit. Maybe one day rec rebreather so I can get closer to marine life and take better pictures but the price, maintenance and work needed is a huge deterrent. Or even cavern but stay outside since cave diving falls into technical diving and have little interest going down that path. Anyway sorry for my rambling I'm very new to the sport and very keen. Any advice and thoughts ? Thank you for your time and have a nice day. Edit: Sorry forgot to add Diver Propulsion Vehicle as well as a speciality Im interested in. Only because it looks cool.

Q: Certification models, BSAC vs PADI.

I was trained and certified in a student branch of BSAC and have always been confused about the training model PADI provides (there are probably other organisations that do similarly but I am not too familiar with those).

BSAC training provides everything needed to safely dive at that level, this includes a lot of things that PADI has split off into "specialty diver courses". Some of the ones I see there make sense as they are outside of the scope most people will most likely encounter like: Diver Propulsion Vehicle and Ice Diver, or are there to educate you for tangential things related to diving that may be of interest: Underwater Photographer and Fish Identification. But a lot to me seem very fundamental skills which are integrated into the BSAC courses. Examples are: Boat Diver, Drift Diver, Drysuit Diver, nitrox, navigation and many more.

BSAC does have the concept of Skills development courses for the courses that are outside the scope of normal diving, more for interest or for courses that you'd need specialized instructors. In the last case they are still required to get the certification (examples are PRM and O2 adiministration for Dive Leader).

On top of this the PADI model of very short 1

Additional content request for R*

At the expense of looking like I don't have a life, I would like to share some ideas that I have been collecting to submit to Rockstar Games as additional content.

Over the past year whenever I had the thought "ya know what... this would be tits!" I wrote it down. This is nothing more than a giant spit ball list but I am curious to see what you guys/gals think or if there are any ideas of your own.

This can be more than a simple request list... PC is just around the corner. Many of these can become reality by the modding community.


β€’ Please bring back more amphibious aircraft like the Leviathan and Sea Swallow (with and without the gun). Since you've brought back the Dodo seaplane it seems that you guys are developing alternative ways to play the game. These vehicles are pivotal for different transportation scenarios and mission possibilities. Imagine flying 8 players in a Leviathan a half mile out to sea, diving/jumping/RAPPELING out of the side panel doors (slidable similarly to the Swift), diving 30 meters down for retrieval of... whatever (briefcase/loot/dead body) off the ocean floor (by purchasable scuba gear option added in the inventory menu, works like the parachute), maybe an underwater battle (knives and harpoons), followed by a massive arial battle/chase (cops, military, rival gang npcs, or other players), pursued by boats and other aircraft over the sea and escaping to land. (Mission). Just the thought that you could have cooperative or competitive players face off in the sea is brilliant. Let's start crossing boats and planes against or with each other and we can start putting that knife to use against other scuba divers. Smoke bomb signals (like the crate drops)? Underwater laser cutters/torches? Flair sticks underwater? Diver propulsion vehicles? The best part about it is you expand the playable map and sandbox experience with content you have already created; the open sea.

β€’ The Flight School update was/is amazing! Please bring back the Rustler (with gun) and the Little Willie gyroplanes/gyrocopters/rotaplanes (would make for some fun tight races) for more arial diversity. Tight gyroplane races would rejuvenate aerial competition.

Description of the recent cave-accident in Norway

Description of the dive in Plurdalen, Norway, February 2014

The plan was to dive in two teams. The first team consisted of two divers (hereafter β€œdiver-1 and 2”), and the second team consisted of three divers (β€œdiver-3, 4 and 5”). The second team was supposed to enter the water two hours after the first team’s start. The planned diving route went from Plura to SteinuglefΓ₯get, overnight in the rented house near the Plura entrance (while gears in the cave), and dive back the following day.

The estimated dive time was five hours, with maximum planned depth of 129 meters. A bail-out plan was communicated with the both teams, and adequate bail-out gas and bailout rebreathers were carried along.

Preparations:

The first team begins to make a hole in the ice at the Plura start site. The second team transports the exchange clothes and gears to SteinuflΓ₯get end. The second team returns to Plura dive starting site and helps the first team to start their dive. After this, the second team starts with their own preparations and begins their dive approximately two hours after the first team.

Dive:

The first team:

The first part of the dive was uneventful. After passing restrictions, which are located just before the maximum depth of 129 meters, the team started to ascend. Diver-2 gets stuck in a restriction at about 110 meters. Despite every effort, diver-2 can’t get out, and faces simultaneously problems with the rebreather.

Diver-1 tries in every way to help, but despite these efforts, diver-2 dies at the restriction. Diver-1 has to continue ascending alone to SteinugleflΓ₯get. Due to the excess time spent at the depth, diver-1’s estimated total dive time increases now from five hours to more than eight hours. This uses all the margins in the dive plan. Diver-1 has to cut about 45 minutes out of the last six-meter decompression stop, but survives without decompression sickness symptoms. Diver-1 stays at the SteinuflΓ₯get waiting for the diver-3, who was already visible in the water during the last decompression stops.

The second team:

The first part of the dive was uneventful. After passing restrictions, which are located just before the maximum depth of 129 meters, the team started to ascend. At 110 meters, diver-3 discovers the body of diver-2. Diver-3 tries to free diver-2, without success. Diver-3 starts to take off own equipment in order to negotiate through the restriction, the deceased, diver-2. At the same time, diver-4 has

Missed Collab Oppurtunity - Subnautica X Fortnite

With this season being ocean-themed, a Subnautica crossover would’ve been perfect!

New Weapon: Stasis Rifle - press or hold down the RMB or Left Trigger to charge the weapon. The longer the charge, the longer the AOE. After release, it will release a ball of energy that once it hits something, it will be frozen or 2 - 10 seconds depending on charge time. Uses a new ammo type, batteries.

New Weapon: Propulsion Cannon - use the RMB or left trigger to select a small object in the environment and pick it up. Then either hit the RMB or Left trigger again to drop it, or hit the LMB or Right trigger to launch the object at high speeds. First structure hit is destroyed no matter what, but the second structure the object hits will be halved in health and the object will disintegrate. Uses new Batteries ammo type.

New AI enemy: The Warpers The Warpers are a half robot-half animal creation of the Almanac designed to container the Kharaa, a deadly virus found on 4546B, where Subnautica takes place. If one spots you, it would fire a rift right at you that is easily dodgable, but if it hits, you will be teleported next to the Warper and it will hit you for 30 health/shield before it wraps somewhere else

New AI enemy: The Sand Shark Sand Sharks are ambush predators that wait in the sands of deeper biomes on 4546B. They would hide under the sand in the waters of the map, and you can tell where they are from their large fin that gives them their name. If you still get too close, it will pounce. It’s not very fast, so you can swim away from it before it gets you, but it will do 20 damage per bite to either your health and shield.

New POI: The Aurora The Aurora is the main ship of Subnautica that you escape from after its shot down by what I like to call the G.U.N. It serves as a landmark and important story piece in the main game, but in Fortnite, it would feature special chests that would drop Shields, Health, Food, and the new weapons I talked about. It would contain lots of metal resources, but it would also contain another AI enemy, the Cave Crawlers. Annoying pests in the main game that can crawl on anything. They are easily dealt with, but if they group up on you, F. The Aurora would be located burning wear The Yacht used to be near Steamy Stacks.

New Vehicle, the PRAWN suit. The prawn suit is a large, mechanical suit the player can use both underwater and on land. It would function as a useful vehicle with three arm attachments you can swap between.

[SECRET] Better late than never

The Second American Civil War has delayed modernization of both the Bradley Fighting Vehicle and M113 Armored Personnel Carrier to such an extent that even the proposed replacements for these vehicles are considered woefully outdated. Given all contenders are now considered unsuitable for modern battlespace standards, the American Republic Department of Defence has commissioned General Dynamics Land Systems and Raytheon for replacement of legacy systems with a new family of IFVs and APCs.

##Pallas Unified Platform System

The Pallas Unified Platform System (PUPS) is an advanced modular heavy military tracked vehicle platform constructed around a hybrid diesel-electric propulsion and drivetrain, with a common armor system, active protection system, and battlespace management artificial intelligence. By sharing the same fundamental chassis, vehicles constructed on PUPS share similar operational characteristics, allowing them to easily maintain organic formations while reducing their maintenance and logistical support footprints. This commonality also allows any factory designed to produce any model in the Pallas family to be quickly retooled for automated production of other members of the series.

Each Pallas hull is constructed around a boron nitride nanotube composite monocoque chassis. In addition to providing high tensile strength and low flammability/conductivity, the structure of the PUPS platform weighs a trivial 500kg, allowing internal volume to be maximized for carrying capacity. The frame is also designed to be self-healing, featuring a layer of BNNTs suspended in quick-hardening polymer resin designed to reinforce cracks and scab over holes in the event of structural damage.

PUPS inherits several key features from the GDLS M1A3A OCU. Propulsion for the Pallas family uses a lightweight derivative of the Abrams’ diesel-electric transmission system, combining a 0.8 MW diesel engine with an Li-air nanowire battery bank protected by a graphene-BNNT composite liner. These are supplemented by several modular quantum glass battery packs, which provide extremely-rapid, on-demand discharge for sudden maneuvers. The hull’s continuous tracked system depends on sixteen road wheels in an 8x8 configuration an

so as an update on BFR on it's own

The production design of the BFR is different in some important ways. from what I presented about a year ago. (2017)

overall it is 118 meters long the payload is similar, about 100 metric tonnes. actually technically 100 metric tonnes all the way to mars with of orbital refueling. BFR is designed to take 100 metric tonnes to Mars, maybe Ceres.

[mentions refueling on Mars to hop to the astroid belt to Jupiter and planet-moon hop to the outer solar system]

BFR is intened as an interplanetary transport system that is capable of getting from earth to anywhere in the solar system as you establish propellant depots along the way.

https://youtu.be/zu7WJD8vpAQ visuals on the payload section

we've increased the payload section to be over a 1000 cubic meters [estimating that the final volume will be around 1100 cubic meters]

there are forward actuated fins and rear actuated fins

the way that BFR flies is somewhat counterintuitive.

there are the two foreward actuated flaps, and two rear actuated... wings... fins... flaps... they aren't exactly comparable to anything else out there.

but you want 4 control surfaces to be able to control the vehical through a wide range of atmospheric densities and velocities

the way it operates is more like a sky diver than an aircraft

for the majority of it's descent it is trying to brake. it's doing everything it can to shed velocity while distributing that force over the most amount of surface area possible.

so 2 of the 3 rear fins actuate like giant wings. it requires an enormous amount of force to move them, in the meganewton class of force. the third fin, does not actuate. it i

[R&D]EDA First Set of Projects Announced

The European Defense Agency has announced the first set of projects jointly developed by member nations. It is expected that this new trend will continue for the foreseeable future, but only time will tell if it turns out to be a success.

The first is a twin-engine 4.5 generation fighter aircraft, meant to be supported by the Eurofighter Squall. It will be partially based off of Sweden's Gripen aircraft line, should they wish to contribute. The Eurofighter Cyclone will have a vtol navalised version designed to launch from aircraft carriers, called the Sea Cyclone. The only difference between the Sea Cyclone and the Cyclone is that the former is a bit smaller and has a slightly reduced range.

Length: 18m

Wingspan: 12m

Height: 4.25m

Wing Area 38 m2

Weight

  • Empty 12,750 kg

  • Typical Load 15,200 kg

  • Max. Takeoff 21,500 kg

Performance

  • Max. Speed: 3,115 kph

  • Initial Climb-Rate: 25,400 m / min

  • Service Ceiling 32,200 m

Range

  • 6,700 km (typical)

  • 4,400 km (max payload)

Engine: Same powerplant used in the Eurofighter Squall.

Armament

Hardpoints: 8 on the wings total, each with a max payload of 500 kg, and 4 internal storage bays with max payload of 800 kg for each bay

Cannon: x1 35mm autocannon with 2,500 RPM

Avionics: Special electronic warfare suite, specialising in jamming other aircraft and ships not on the correct channel

Radar: Same present in Eurofighter Squall

Infrared Sensors: Regular IRST

Touchscreen To be developed for cockpit

Missile defense: Countermeasures present on the Eurofighter Squall

Stealth Systems: Small focus on this, this aircraft will rely on speed to avoid threats

Misc: Due to requests from Scandinavian nations, the Eurofighter Cyclone will be especially adept at remaining operational in arctic or otherwise maleficent weather conditions.

This project will be completed by 2023 and will cost a total of 14bn to develop, with a first time unit cost of 110 million USD, to fall to 85 million USD after 5 years of production.


The next project announced is the Eurocopter Jaguar, a new all weather attack helicopter. It is designed with two purposes in mind: one to destroy large and clumped armoured forces and the other is to provide close air support in low intensity environments, such as those encountered in Afghanistan.

[R&D] Gotland Class Midlife Update

The Gotland-class submarines of the Swedish Navy are modern diesel-electric submarines. They are the first submarines in the world to feature a Stirling engine air-independent propulsion (AIP) system, which extends their underwater endurance from a few days to weeks. This capability had previously only been available with nuclear-powered submarines. It's due to receive a mid-life update in 2019. These new capabilities will solidify the Gotland Class as the stealthiest Diesel Submarine in the World.

Gotland Class Midlife Update

Engine and Stealth

Engine Stealth will be further upgraded. These will include a new extremely resilient platform technique incorporating extensive rubber mountings and baffles is used to minimise noise from operating machines and transient noise, as well as absorbing shocks. To further reduce emitted noise, the space between the frames is equipped with acoustic damping plates.This approach is used in combination with, for example, encapsulated Stirling and diesel engine modules; flexible hoses and compensators; and specifying maximum flow speed in air ducts, minimum bending radius on cables and pipes, and the design of out-board holes and cavities.

The target strength of the Gotland-M submarine will be minimal thanks to a new type of surface acoustic absorption and reflection coatings. This highly optimized design also cuts the hydrodynamic signatures and flow noise around the submarine, both in deep water and near the surface.

The magnetic signature is suppressed by an advanced degaussing system that is controlled by external sensors to facilitate compensation in all geographical locations and headings. Galvanic signatures, primarily electrical but including secondary magnetic signatures are reduced by a specially designed cathodic protection system and careful material selection that minimise electrical signatures without compromising the corrosion protection of the submarine.

The Torpedo tubes will be fitted with a new development from SAAB, a water ram expulsion system, which ejects the torpedo with water pressure to avoid acoustic detection.

Sensors and Detection

The Gotland-M will use the new SAAB UME-250 Sub-Surface Tactical ESM and ELINT System. The systems are all capable of operating in blue water or in the littorals, and feature a multi-receiver parallel architecture, with integrated CW immunity, Β providing the capability of rapid reaction time, in high pulse densities with high sensitivity, and ELIN

[R&D] Type 334 Minehunter (Marburg class)

As a replacement for the 30-year-old Frankenthal-class minehunters (Type 332), the German Navy has commissioned the development and construction of a new class for the role: The Type 334, alternatively known as Marburg class, will be built by the shipyard Abeking & Rasmussen.

As a first for the German Navy, the Type 334 will be built in a catamaran design made of degaussed steel and composite materials. These measures will minimize the magnetic, acoustic and pressure signatures to ensure safe navigation in mine-infested waters.


The Type 334 is primarily intended to execute its role as command and sensor post for the operations of unmanned vehicles, both on and below the surface. Two new unmanned vessels will be developed for the German Navy to fit this role: The Seefuchs 2 UUV and the Delfin USV. Both will be developed by Atlas Elektronik based on existing models.

  • The Seefuchs 2 (Seafox 2) unmanned underwater vehicle will be the successor to the successful original Seafox. Compared to its predecessor it will receive a greater range, improved maneuverability and much better sensors (new synthetic aperture sonar, etc). These upgrades will allow significant improvements to anti-mine capabilities with superior identification and destruction ability.

  • The Delfin (Dolphin) unmanned surface vehicle will be a purpose-engineered improvement of the ARCIMS system. ARCIMS is a modern, modular platform for mine counter-measure and other operations. Delfin will receive some general spec improvements to its range and payload capacities, as well as other crucial features to optimize it for counter-mine utilization.
    Delfin will be optimized for several functions: Detect mines and threats using on-board and towed sonars, eliminate mines by sweeping with synthetic magnetic fields and acoustic signals, and remotely deploy or retrieve Seefuchs drones.

Like the original ARCIMS, Delfin will of course also be compatible with modular components to perform hydrography, coastal patrol, ASW and other missions.
It will shine with a high speed (40+ knots), allowing great mobility. Furthermore, it will be simple to move separate from the ship over land and by aerial

[TECH] SSN(NG) Program.

The Virginia class was designed as a lower cost alternative to the Seawolf, as a result of the end of the Cold War and the reduction in need for such a capable submarine. However, the PSA now sees the situation changing - with the international threat profile rising, the PSN now needs the most capable submarine possible.

The SSN(NG) program is the result. Led by General Dynamics NASSCO, the SSN(NG) is designed around the innovations that have happened in autonomous underwater vehicles, allowing it to operate at longer range and lower risk.

Tethered AUVs were never particularly well-liked by submariners, because their tether means that the submarine cannot turn to some angles without the risk of tangling the propeller. While very thin and light tethers reduce this risk somewhat, their use is still rather fraught.

To solve this problem, the SSN(NG) has an accompanying AUV, called the tether tug, that is launched from the SSN(NG)'s torpedo tubes amidships and then runs on electrical power from the submarine. When an AUV is launched from the SSN, the tether tug automatically picks up the tether from the launched ROV, and keeps the tether away from the propellers.

This system, while complicated, allows the SSN(NG) full freedom of movement, even while operating numerous ROVs at potentially extreme range.

Building off of the Virginia, the SSN(NG) will also offer a much larger special forces/operations bay, with spacious areas that can be flooded and opened to the sea, both for employment of divers and for the use of technical equipment in the open water. This system allows the SSN(NG) to operate numerous mission modules, including an underwater cablelaying module and ROV maintenance space.

Acoustic stealth will be accomplished through both specially designed acoustic materials and shaping, as well as new active cancellation systems, allowing the submarine to effectively mimic the ambient noise. Moreover, the SSN(NG) will support flow noise and anomalous current reduction features, allowing the submarine to avoid making submarine wakes.

Lastly, the SSN(NG) innovates in its optronics and ESM suite through the use of a second type of utility AUV that carries the periscope and ESM system, allowing the submarine to stay deep while the AUV carrying the surface protrusions allows surveillance at the surface. The submarine will carry 3 of these optronics AUVs, providing the ability to surveil potentially quite distant locations at low ownship risk, and they can co

Squad's next mission: Kerbal Maritime Engineering?

Even though 1.0 isn't out yet, I'm already thinking about what the folks at Squad could do next with their talents. I love the basic formula of Kerbal Space Program, but the two most striking features of the game for me are the incredible buzz of exploration and its engagement with real world scientific principles. I've had some of my greatest thrills from reaching the surface of another planet in KSP, and all this without deliberately killing anyone for once. I've also learned a bunch of interesting and important concepts and come away with a renewed interest in space exploration and astrophysics.

So, for Squad's next game, there's one obvious way to extend the KSP model: take it underwater. The same basic game mechanics could see us sending our Kerbals (Merbals?) surfing the waves and descending to the depths of the ocean in pursuit of Science and Funds. Think about some of the cool stuff this could involve -

  • A bunch of different propulsion methods with their pros and cons: sail, steam, diesel turbines, hovercrafts, and nuclear reactors.

  • Lots of environmental hazards, from treacherous weather conditions on the surface to decompression issues and oxygen crises in the depths.

  • A variety of techniques and technologies for specialized exploration (you might need to research things like tri-mix and rebreathers for your kerbals to go underwater, or ice-breakers and dry suits for polar research).

  • Deep water exploration in mini-subs and diving suits.

  • Fun mini-vehicles like jetskis, speedboats, and surfboards.

  • Tons of fun contracts, from simpler oceanographic surveys, transport missions, and races in surface vessels to underwater recovery and exploration missions, or even construction of underwater bases.

Imagine how cool it would be to explore the Challenger Deep in a minisub, plow through frozen ice to reach the north pole, or send a highly-trained diver to retrieve science samples from an undersea vent! Plus I can imagine this kind of game teaching people a lot of cool scientific and engineering principles - from simple stuff like how to tack a sailboat to more complicated ideas like navigation and the need for [decompression stops](http://en.wikipedia.org/wi

Welcome to /r/oceandrones

Welcome to /r/oceandrones. Oceandrones was started to give people a place to talk about aquatic drones. The main purpose is for designing an ocean drone project that will ultimately scan the entirety of the ocean floor and figure out what is going on down there using DIY thinking and ingenuity.

The initial conception is to have a moving base that gathers the drones data and refuels the power of the drones that go out and scours the ocean floor and ocean itself.

The drones themselves will dock inside the moving base. Each drone will have responsibilities and act automonomously for the most part. There will be times that drones will be remote controlled in order to gather more specific data or for other purposes that have yet to be determined.

The main job of the subscribers to this sub-reddit will be to aid in the development of the ocean drone design stages. If you are a mechanical engineer, electrical engineer, marine biologist, diver, RC boater, RC submarine enthusiast, RC aerial vehicle enthusiast (might be some use for air missions / needs), programmer, communication enthusiast, or anyone with an ability that might provide aid to this project, we are welcome to have you.

Current topics to cover:

  • Power supply on the drones
  • Power generation methods
  • Data storage of the drones
  • Data storage on board the docking station
  • Autonomous programming
  • Vision technologies to utilize (color nightvision, 3D sonar, etc.)
  • Propulsion methods of the drones
  • Propulsion methods of the mobile docking station
  • What pieces of data to collect
  • Problems that we will encounter (go for it people with an axe to grind)
  • Control / communication methods underwater and above water

What else do we need to cover?

Questions Answers
How does your body feel after being in space for 6 months? Adapted. You feel like a spaceling. You feel completely normal, and don't even remember that you're flying. There is no up or down. You are really no longer an earthling, but a spaceling.
Are you excited to meet the ISS robot: Humanoid Kino Bot in 2013? I know of Robonaut on board, but I'm more excited to see Canadarm 2 again. It is a much more capable robot.
How did it feel when your saw earth from space for the first time? It feels like someone's revealing a secret to you. Like you're getting to see something magic for the first time. It feels like an honour. Like a huge privilege.
How does the humanoid robot move around the station i can find any information on that. Robonaut works in a fixed location inside ISS. We put it in place. There are plans to bring up legs for it, and eventually it will be able to move on it own, but it's still in early testing and certification.
How bright are the lights on Earth when you are in orbit at night? How does it compare to the stars we see on the surface of Earth? Yes, it looks like stars from the surface of the earth, but not nearly as bright as the moon. The brightest things are lightning storms. You can see lightning storms at night for thousands of kilometers. Regular lights just look like stars from the earth. Big cities stand out as one big local glow.
This is an excellent question. Nobody ever asks this.

[To facilitate getting less repeat questions from the last AMA, what I've done is answered a number of the "standard" interview questions up front, including those sent to my son in PMs the other day. I will provide them below in i
