What are DISNEY rockets?
"'Disney' Rocket-Assisted Bomb
Designed by Captain Terrell RN of the UK, this 4,500 lb (2040 kg) hard-case streamlined bomb was intended to be used against U-boat pens and other super-hardened targets.
Dropped from 20,000 ft (6096 m) the bomb had a barometric fuze which activated at 5,000 ft (1525 m.) At this point a rocket in the tail of the bomb fired bringing the impact velocity up to 2,400 ft/sec (730 m/sec.)
Carried on B-17 bombers in pairs under-wing this weapon was first used on Febuary 10, 1945. Nine B-17s of the 92nd BG dropped eighteen Disney bombs on U-boat pens at Ijmuden in Holland, scoring one direct hit. The weapon saw further use but suitable targets were often either too far away (such as in Norway) or already over-run by Allied troops. Still by the end of the war a total of 158 Disney Bombs had been used in combat. "
