Placing the Bell P39 Aircobra.

[Juha]

"The statistic about failures to explode are irrelevant to anti-tank warfare, where solid-head shot is used."

Graham, that was original intention, 60lb HE against ships and 25lb solid head against tanks but after tests that was switched to 60lb HE warheads against tanks and 25lb solid head against ships and subs.

Reasons: solid head didn't have enough penetration power against Tigers and solid heads had passable underwater trajectory and were effective to hole hulls under waterline.
