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.

Good but could be better

I just got the game last week and I’m 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) I 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, it’s 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 I love the game and I’m hoping that there will be updates to address many of the missing elements coming in the future.

Everything I wanted, but has room for further development

This game was everything I expected, I really wanted a simple submarine sim that wasn’t 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 I-400 would be a great addition, now you could be able to play from both sides. I believe that if you add more and different submarines, you can get some with anti aircraft capabilities that come with them. This brings me to my 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. I believe these two additions would make this game even more enjoyable and am looking forward to the future.

Needs specific missions

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 I'm missing something I can only get that info currently if I'm at periscope depth. Strategically, there are battles where I don't want to raise the scope UNTIL the torpedoes are re-loaded and ready to fire.
