I'm sorry to take up some of your time. I'll try my best to make the suggestions easy to understand. If there is any tone problem, please forgive me.
Some version updates are recommended for 2.0
Now that it's time to update 2.0, why not make a big update?
Part damage
Now that the cannon has been added, the game has a richer playing method, but the powerful weapons and fragile works seem to be a little inconsistent, so I suggest adding a "collision and explosion damage coefficient (1)" to all parts to make the parts stronger (0) or more fragile (+ ∞), so that the players can make stronger works to increase the fun of the war.Or simply add options that will not affect other parts after the parts are destroyed.
Visual enjoyment
At present, the effect of cannon seems to be a little unsatisfactory. I think it will look good to increase the smoke of cannon. If the effect of weapon explosion in water is water column, it will be better. In addition, can underwater camera mod be considered?
weapons
I suggest removing weapons such as bombs and missiles that will disappear in deep water, adding the option of hiding the somke tail to missiles or rockets, and adding the option of exploding when bombs fall into the water after being launched.
AI
Can you add some new sea targets? For example, World War II large aircraft carrier, transport ship. Plus, USS beast is twice as big and the destroyer is smaller than real size.
Parts
Like adding an engine that doesn't need air and works underwater?
Thank you for taking the time out of your busy schedule to read. I hope you can consider some of my suggestions.
