If I already have an original ship(tier B), can I upgrade it to tier A or S by collecting debris ?

Oh. This should not be possible..... I want to delete this comment.....

Sonar is more used for target detection. Surface ships have the same radar system for target detection, but this does not mean that they have the same sight range. Submarine's attack on surface targets relies more on periscope, so their sight range can not be too wide, and deep diving can not see anything.

We can changed it to continue to scan the target at the radar interface of the upper right corner when the submarine is diving , just like a radar on a normal surface ship.

In fact, these proposals will not cause too much damage to the submarine. A skilled, seasoned and conscious player can play a huge role as usual. At the same time, the significance of reconnaissance will be more important

Hello everyone, I think the submarine should make some preliminary reasonable balance correction.

1) Reduce the sight range of the submarine and further reduce it after diving. And deep dive have no sight range (similar smoke bomb)

2) When the HP is less than 85% (or more reasonable proportion value), diving will slowly reduce hp , deep dive will double speed to reduce the HP .

The main purpose of the above two points is to increase the operation difficulty of the submarine without reducing damage, speed and oxygen, and is more interesting and fair. Most players should be able to accept it

Hi! I want to make a suggestion to the chat channel. I think the public chat channel should be divided into 3 parts, the global channel, the local channel and the fleet channel (like the picture in the following). The local channel is grouped according to the language chosen by the player in the settings.This will be more reasonable and useful than the East and West channels.

PS:I'm very, very, very much looking forward to updating 4.0.0.

PS2:Sorry for my poor English.
