So my question: why there is no more DECK GUN installed on modern submarines? You gotta have it for personal defence or to take a pot shot at small ships right?

If its not a  good sub, there will be no new customers for the manufacturer. Till now 4 countries are using scorpene. What makes it good is..... the hydrodynamic shape of the hull which among the most silent sub ever built. It can carry many weapons compared to other conventional subs.

But dont compare with SSN.....its in other class. They have forever powerplant & speed

Almost all of us said heavier....which is true. But wrong reason... only u gave the closest answer.

Here is the answer....

As we know fuel oil is lighter than water. When we consumed oil, we cant leave the tank empty. The vapour inside, with the pressure effect can create diesel effect which can cause explosion. So, the avoid that, seawater will be filled inside, hence sub becomes heavier. To compensate, we have to drain some other water tanks. Balancing a sub is a trickier job.....
