Without doubt it has to be the proxy torps. Even though SS is easy mode, the proxies make
it even easier to get attack without aiming.

Also, it's a partial fix for the under-ship-torp bug. If the enemy ship is turning, or
their heading is close to that of the torp it will proxy on the other side after going under.

The other great thing about KM subs, is you get to level the crew in a Moltke - what more
can you ask?

tiny size, fast turning and with mine launcher and proxy torps. Stay with your BB's and if
you see enemy sub, force him to crash dive and them drop a mine over where he dived. He
cant move when in crit so he'll have to surface into your mine

personally, i hate the SS1. i just spent lots of time AAing in an emden to SS2.

i thought it had almost no air, and was really slow. along with only 3 torps.

Although it can carry mines, which is fun, for 2 minutes. ^^

Smallest ship in the game...

Proxy torps...

Mine Launcher with a 1.5 second reload...

Did I miss any?

the turning force, makes them great defensive subs, the ss1 has mine launchers, which
give the ss1 a nice advantage.
