Top Ten Submarines....

[subvers4]

Nice one Danlisa, well spotted. It depends on what you call a " proper submarine " I guess. My own personal opinion is that submarine warfare ( according to effectiveness ), peaked during the second world war. The theory was immaculate, the enemy was an island nation, surrounded by sea, cut off the sea routes and the supply routes are stopped. your enemy is then reduced to a small nation engaged in a siege situation. Provided this is not diluted, it is only a matter of time before you emerge victorious. Patience is a virtue. But as we all know, things can and do change, and success depends on how you adapt to changes. However, the type V11 was a very effective and efficient " bogey man ". Perfect for the period, and type of warfare it was used for.
