US submarine service had about 20% , merchant marine had 4% according to this report. Guess they are comparing Navy, Airforce and Army. But roll the subs off into their own and its highest

Good point - and I read that the German U-boats lost about 70% of their crews.

Yeah they were all bad Germany had the most, then Japanese and then american. Other countries were just statistical blips due to relative low usage

By the end of the war the allies had figured out how to deal with submarine technology of the era. Escorted Convoys made attacks dangerous and near constant aerial patrol by heavy bombers meant that as a submarine surfaced to recharge its battery and replenish its air it'd be reported and hunted.

Another overlooked measure that significantly reduced the threat of U-boats was improvements to radar that allowed ships to detect the conning towers of submarines from beyond the horizon and even their periscopes.

By mid-war the British had air based radar that could detect a periscope or snorkel in the water, by the end it was just damn unsporting.

I think that's the UK's Bomber Command. US Army Air Corps 8th Air Force losses were in the 7% range.
