HMS D6 Submarine (Malin Head — 280 fsw)

The HMS D6 submarine is located in deep waters off Malin Head. It is notable for being the first British submarine with a deck gun. The D6 sank after being hit by a torpedo from UB-73 in 1918. Only two of its crew survived the sinking. Diving this wreck can present challenges due to its depth and low light conditions, but the experience is unique and memorable.
