They're unique. Originally designed to power fast torpedo boats during WW2, three of these powerful and compact engines would churn out plenty of power for the boat up to 50 kt.

They're still in use by our UK navy. Nine minesweepers still on active duty.

I just realised they re-engined them with cat engines in 2008. Pity.
