The principal bomb used by the A4B/C during the war was the Mk-17.
The Dagger used also Mk-17 and Spanish built BR-250.
Finally the A4Q (Navy Aviation) were using Mk-82 with Snake tail.
Most of the Mk-17 did not explode after impact. One of the reasons was the high mass of the bomb wich after hitting the not so strong ships go through it to the sea.
As you can remember during May 25th attack to the HMS Broadboard at least one bomb hit the ship helicopter hangar, distroyed the helicopter and made a hole before exploding in the sea.
The other problem was the very very low level at the pilots were flying before lunching the bombs. So the fuses could not have time to arm the bomb.
The Mk-82 were more effective, those were disign for the job and the Navy Pilots were trained for the job well before the war.
I don't understand why my country army forces didn't cooperate giving the Navy Mk-82 Snake to the Air Force....
