What Makes Silent Depth Submarine Sim Stand Out

Welcome to Silent Depth, the first real 3d submarine simulation for mobile devices. Being a member of the Silent Service of the US Navy you take command of a Gato/Balao class submarine and go on extended patrols in the dangerous waters of the Pacific in world war II. Your task is to attack Japanese merchant ships without being caught by destroyer escorts either using your torpedo weapons or your deck gun in a realistic environment. Control your submarine, use your strengths and find the weak spots of your enemy. Only that way you have a chance to survive this thrilling 3d simulation. Run silent, run deep!

No ads, no in-app purchases, just the full game for one price. Free updates for the life time – and there will be much more content to come! Attacking war planes, medals, achievements, missions to name a few.

Player Experience Highlights

Community Insight:

Game is tons of fun Some ideas Needs a pause button in menu Every once in a while there are still ships that are going zero knots and cant be sunk and you cant escape the game No way to see the deck gun remaining ammo in the information screen Please keep on updating the app.


Its a good game but we think it needs a graphic overhaul and being able to go below test depth because the fleet submarines could usually go below test depth relatively safely.


We tried App Support but no Contact Us there. So we get these generic Ships that move at 0 knots when Im pretty sure they are supposed to be warships. We get them where there should be an escort mostly. Or when a cruiser and destroyer might be traveling together. But the worst is when they show up in a battle group. There will be a carrier and a battleship and Ships that do nothing. So the carrier/battleship are just sitting ducks. Hope you can help. Otherwise, a fun game.


It took us a while to figure this out.but this is a game where you MUST NOT DIE, or you lose everything and literally start from scratch. So if youre even close to being killed,close the app and start your saved game again. People claim that getting medals is impossible. Not truebut you wont get them if you keep getting killed.


We want to like this game. Starting out, driving the sub out of harbor, so exciting. But the excitement quickly ends. You sail towards your patrol area, and will suddenly encounter a small target. Not only in the middle of nowhere, but technically in US waters. What is this freighter doing way out here? When you do encounter a ship, suddenly they are barely 2nm away if not closer. The game takes away the entire skill and thrill of stalking a convoy. And the graphics! The map view, has glyphs for your sub and other contacts, looking wildly out of place for a WWII simulator. It should look like grease pencil markings, instead it looks like a modern naval simulator on top of a cheap reproduction of a map. The worst part of the map view, is it doesnt show the torpedo tracks! So while it shows accurate glyphs of each ship, you have no idea where your torpedoes are. Then the worst part, which should be a celebration, is when you sink a ship. Nothing happens. You check the map, the red glyph is just gone! XO not gonna confirm the tonnage sunk?! He confirmed every single rudder change saying rudder amidship but when you finally sink something hes weirdly silent? The single moment you are playing the game for, and theres zero recognition or celebration. And it gets worse! If you are stupid enough to keep playing it, you literally run out of targets. Its as if theres a fixed number of ships in its universe, and after 4 or 5 patrols, they are just all gone. Ive driven patrols around Japan without a single contact. And over Japan. You can just directly sail over Japan. Why worry about where there is land? Just sail right across! And we can keep going. The toolbar at top is weirdly complicated. Separate buttons for periscope view and top of sail view. Should just be a single button. And a pointless 3D view button – looks great, but doesnt make sense, how is this 3D view even possible? We have to carefully set every throttle and rudder and depth setting, but somehow we can freely fly around the ship with a 3D view? To fix, its really not much: – map view should look more like an actual map, with grease pencil markings for ships and torpedo tracks – scratch the 3D view – only a single binocular view button in toolbar, which goes to periscope if up, or sail view if surfaced – ship systems button is pointless, certainly not needed at top toolbar – binocular and deck gun view are wildly difficult to keep on target. Need an ability to keep locked on – engage targets at more like 8nm, let us enjoy the hunt – why no missions to pick up airmen or other special missions? Overall would be great to feel more like a Captain, and just direct things, rather than having to press every button correctly. And why are there never any aerial threats/targets? The overall engine is close, Id be endless thrilled with something only a little bit better. But this isnt it.


Bad equipment false data but over all the game is ok.


Paid 5 bucks for this game as it made us think of Silent Runner, an old console game. This could be a great game if it were not full of bugs: ships that dont show on the screen, inaccurate distance indicators, ship not turning when rudder is full right or left often we had to restart the game, lose progress to continue game play. Game could also benefit from improvements such as target zoom, ability to attack docked ships, AA Gun. As it is, it is not worth the investment.


The game resets to the beginning after getting passed 2 months. We paid for this app so please fix it.


We love this naval combat submarine game, but however, it would be a lot better to have infinite reloads for the deck gun on the submarine, especially missions to escort allied aircraft carriers and including other friendly vessels like allied destroyers, battleships, cruisers and allied submarines, attacking enemy aircraft carriers, enemy cruisers, torpedoing enemy battleships, battling against enemy submarines, destroying enemy destroyers and infiltrating enemy naval ports.


We are getting unidentified ships that travel at 0 knots- but still can increase distance while sub is standing still (The ships view like cruisers or destroyers) Sometimes on the bridge view the rudder is missing Bring back oil debris and junkcounter measures- that the PC game had Please dont abandon the game on IOS.


Love this game a ton and play it all the time, the only reason we stopped playing was because when we set a certain depth, the sub went down but when we tried to re-surface it would not do anything. Its a glitch maybe? Please fix.


In addition to the comments others have made, we have experienced encounters were none of the ships are identified. They are clearly destroyers and light cruisers, but they are identified in the game as simply ship. When sunk they go the correct tonnage. But it worse they dont attack. They usually accompany carrier and battleships in the large targets, but we have had it happen in medium too. Another fix is that sometimes the crew will not reload torpedos. We have had to run from large targets because we empty the FWD and AFT tubes, but it wont reload. There are usually a couple more destroyers to sink and we can do anything about with torpedos. Great start to a game, but needs many fixes.


This is by far one of the better WW2 simulator games Ive played on a device. We love that we dont have to calculate exactly when to fire the torpedoes based on distance speed and trajectory. However a few notes 1) we feel like the patrol zone should change every time you return to port to refuel and rearm. Half the time when Im supposed to patrol a zone on the other side of the map, we use up have our fuel getting from Wake/Midway Islands just to the patrol zone. We even engage some ships as well, making our stay in the zone even shorter. 2) Some of the large Japanese fleets that Ive encountered, numbering around 10-12 ships, glitch. To the point where it doesnt even identify what type they are, it just says ship. It also doesnt give a speed reading, it says 0 kts. Which is fine we suppose but when we try to sink them they wont go down. 3) Air cover. We recently attacked an aircraft carrier in the game in broad daylight. We were even surfaced. And we sank it easily (minus dodging defending destroyers and cruisers). One addition we would like to see is the addition of Japanese planes actually attacking. Whether from carriers, or, if the patrol zone is closer to Japan, then from the sky. This would incorporate the use of the anti aircraft gun on your sub, instead of it just being there and us not being able to use it. 4) Decoys. Decoys were a staple of submarine warfare of that time, so maybe and additional button for us to launch decoys in case we get swarmed too heavily by Japanese ships would be a plus. Otherwise, awesome game.


This game is great overall but an update is needed to fix the submarines you command in war patrol so they can be actual to real us subs used in the Pacific during World War II.


Could you please add first person so you can walk around the submarine as you do in the PC game Wolfpack and please keep the 360 button while you add free roam.


First this is a good game keep up the good work. But the AI are like not that smart. And most of the time we just stay on the surface when theres a destroy.


Can you add Japanese submarines.


This is the only real sub game in the App Store Crash dive is good but more of an arcade game. This game will have you playing for years .:we dont bother attacking small or medium targets only large because the map is to big and we dont want to go back to resupply our sub taking on a large group ( carrier) with destroyer escorts will test you every time its never the same , this is the only real sub game we love this game and Ive been playing since it came out we end our night every nite playing this game.


This game is great. Is it perfect? No. Like the feet that if you lock your phone you have to load back in. But it is a mobile game. Its basically silent hunter 4 on mobile. Its open world, Saves once you leave the game, and has pretty good sound design and graphics for a mobile game. Probably our favorite mobile game.


This is like silent hunter 5 battle of the Atlantic lots of boats best game ever please reply.


We enjoy many aspects of this simulation however after the latest upgrade the game now automatically takes the boat to 600 feet when resuming from a saved game. The game will not Let you correct the depth and continues with the loss of boat and crew posting: Game Over! We have tried deleting and reinstalling the game with no success in eliminating this action.


This is a very high quality & realistic sub sim in our opinion. Everything from the physics to details is impressive as are the 3D views. Please add a Battle of the Atlantic campaign. Keep up the great work.

We were looking for a submarine sim that didnt take a week to learn to play, but had enough sim strategy in it. We found this one. It reminds us of Silent Service, which we played in the 80s on our Atari 800. We will one day soon get a more in-depth sim for the PC, but we enjoy this on our PC and IOS. Good graphics on iPad and PC. We hope the developers keep this up to date.


This game was everything we expected, we really wanted a simple submarine sim that wasnt too easy nor too hard. Though this game is already fun, it would be cool to see some more content. For example, adding Japanese submarines you can use like the type b or we-400 would be a great addition, now you could be able to play from both sides. We believe that if you add more and different submarines, you can get some with anti aircraft capabilities that come with them. This brings us to our last addition. It would be cool to see recon aircraft that try to attack you and bomb you when you are at surface- periscope depth. We believe these two additions would make this game even more enjoyable and am looking forward to the future.


We just got the game last week and Im really enjoying it. What it does well, it does very well. But there are some strange missing elements. 1) no radar. Radio was instrumental in the submarine battle in the Pacific during the World War II. 2) we cannot seem to find any clear isothermal layers to hide under. 3) once discovered by destroyers, it seems impossible to hide from them. Even at the easiest level. And related to that, its strange that the depth charges make no sound. That kind of explosion would riddle through the hull . 4) there seems to be no way to raise or lower the periscope without changing your depth. Subs could stay at periscope depth only raising the periscope when needed. This seems like a strange omission. Still however we love the game and Im hoping that there will be updates to address many of the missing elements coming in the future.


Last update still didnt put torpedoes on our maps, but otherwise a nice diversion.


Game play is very good, aided by good graphics and sound. Launchable counter measures, oil slick and debris decoys, and more specific, more limited, more targeted missions could improve the experience. The only major software glitch is frequent uncommanded, instant, excursions below test depth or to the surface, both of which happen at the least opportune moments.


This is one of the best submarine simulators for mobil devices that we have found. The last update brought some great new features and graphics however it also added several bugs that were not there before. There is discrepancy between map view and periscope view. Ships are not in the same bearing or range as the map shows. If we pause or save a game while engaged in battle the game resumes with the sub suddenly on the surface, being shelled. These bugs are frustrating and have resulted in abandonment of the game until the next update when we hope these issues will be corrected. We also hope to see new features and missions with new upgrades.


Not what we expected game to slow graphics not very good not sharp ,not real ,had a game called Silent hunters was a great game graphics were excellent and was fun to play ,this cant wait to get over ,or punch stop.Sorry Chris12 also wish we could get our money back.


We dont like it and wants our money back no offense but the graphic is not as good as we thought.


Nice try…but not completely bug free. Relative position and motion of targets tend to become less and less accurate during play to the point that the targets disappear even though still in map view thus making it unplayable. Had to remove it.


Numerous problems since last update. Not reliably playable at present.


We can see there is potential but it just seems to be incomplete.


Is it a perfect game? No. Is it a game we play often? No. But it is a good game, for mobile. You cant expect the world from a mobile game. It is a fun semi realistic submarine sim.


Our grand son loved this game so much that we installed it on his iPad, but it won't play. Is there a memory requirement.


What is there is awesome. The graphics are good and it is fun to play but you always want more. 1) No medals, it has a place for medals but never have seen one. 2) we were led to believe there would be two classes of subs and more variety of enemy ships. 3) except for home base there are no graphics for islands or ports. Silent hunter 1 (the only good one) had opportunity to infiltrate enemy ports. 4) no specific missions 5) Silent Hunter 1 had a "ward room" or something where you could go in anytime and check your log book and keep track of progress and past missions. We would recommend an update that has been promised but never came.


Deck gun has no range finders thus its useless. No torpedo computer thus lots of wasted torpedoes. No ping sounds from enemy ship. Destroyers magically swerve around most torpedoes. Too few torpedoes on board. Takes far too many torpedoes to sink enemy ships. No log book to review and analyze. Difficult to see.


The graphics are nicely done and the game leans more towards simulation than a Call of Duty on water knock-off some of the other comments complain about. Overall we have gone on several patrols and enjoyed the weather effects, fog of war etc…its all there. Our only request would be a higher variety of missions (sandbox atm) and war targets.


Wish you guys would update it more often. We would pay. Cant find any submarine simulators out there that are this quality.


Love the game, works fine on iPhone sound is great, but just bought a new iPad Pro and the sound doesn't work tried menu everything was set for sound and volume was turned up but still no sound,any ideas.


You have done a great job starting this sim out. Of course everyone wants more, more, more. We're sure as time goes on, with more interest, things can and will be improved. Graphics are great, having served upon this class Sub back in the day. Have to say great job all around. Just waiting for our medals to show up. Wait we all ready got the real ones. Keep up the great work. Take her Down, Take Her Deep.


After last update game no longer works. Problem fixed with new update.


The latest update fixed everything. Well done! We would like to see a campaign mode but this game rocks without it. Great simulator.


Would be good to add missions like search and destroy where one has to do recon to identify and sink certain vessels (if discernible) or interdict certain convoys at a probable location. Also, and this is critical, we should be able to see the torpedo load/ready state on the ship info/damage page as well. Unless we're missing something we can only get that info currently if we're at periscope depth. Strategically, there are battles where we don't want to raise the scope UNTIL the torpedoes are re-loaded and ready to fire.


This is a great game but there are a couple of issues with it. 1.You can't walk around your submarine which we think would be great. 2.You can't get off your submarine or upgrade it. 3.You can't choose missions. 4.The crush depth isn't labeled so we're afraid to go below 200ft which you can still very well be depth charged at.


We've been waiting a long time to play Silent Hunter on a Mac OS. This is a great start! But compared to Silent Hunter 4, it has a ways to go. On the big map, too much time is wasted finding challenging encounters, we.e. Big targets along with destroyers and cruisers to protect them.


Great game, good graphics, easy to use. Only reason why we have it two starts is due to attacking any kind of destroyers. It doesn't matter how many torpedoes, or how well you are trying to evade them, they seem to find you and destroy you with you unable to kill them.


It is a decent app, but like a lot of comments said, could use more. Also would be great if they would fix the bug that causes the sim to not reload torpedoes.


We wish we could rate this game higher, but who puts out a WWll Sub-Sim without sonar? Targets must be acquired, and attack runs executed, visually. There is auto-targeting of the torpedoes, but not of the deck gun. Using the deck gun requires approaching to within less than 800 yards, and then guessing at the range. Also, using the deck gun frequently causes the inadvertent selection of reverse thrust because of an overly sensitive thrust selector located within the deck gun sight picture. There is great potential here, if these problems are addressed, we will re-submit a new review.
