Bombs came in a variety of types depending on the target. Among them were air-laid mines, high-explosive bombs ranging up to the twelve-thousand-pound Tallboys and the twenty-two thousand pound Grand Slams, incendiary bombs and target indicators. Some were designed for blast effect, others for penetration. The fusing and loading of bombs was under taken by ground crew armourers. Bombs were delivered under the aircraft on trolleys towed by tractors such as the David Brown VIG 1/462.

Main bomb types included:
