Armament
Guns
- one 12-in 40 cal Mark IX, 50 shells
The 12-in gun could train 15 degrees to either side, elevate 20 degrees or depress 5 degrees.
It proved remarkably workable, and even after the war the British were considering how this might be preferable as an anti-submarine weapon to firing a spread of torpedoes. The submarine was able to transition from periscope depth to firing depth in 25 seconds, and to return to periscope depth after firing in 15 seconds.[2] Unfortunately, the gun had to be reloaded in the surface.
Torpedoes
M 1, M 2:
- four 18-in tubes forward, eight torpedoes
M 3:
- four 21-in tubes forward, eight torpedoes
Mines
M 3 was converted to a minelaying submarine in 1927. She had a capacity for 100 mines, which were laid off the stern.
