The Mark 101 Lulu was an airdropped

patrol planes. Neither the Lulu nor any other kind of nuclear antisubmarine or antiship weapon was ever used in combat by any country.

The Mk-101 "Lulu" started to be replaced by the multipurpose B57 nuclear bomb during the mid-1960s. The B-57 was a bomb that could be used by tactical aircraft against land targets, as well as a nuclear depth charge.[1]

The Mk-101 "Lulu" had a length of 7 ft 6 in (2.29 m), diameter of 1 ft 6 in (46 cm), and weighed 1,200 lb (540 kg). In RAF service for carriage by Shackleton MR2 and MR3 maritime patrol bombers it was known as Bomb, AS, 1200 lb, MC.

The Lulu lacked an important safety/arming device: it had no sensors to detect the freefall from an aircraft that would follow from the depth charge's being intentionally dropped. As a result, if an armed Mk 101 bomb accidentally fell off an aircraft while it was parked on the deck of a warship, and then it rolled overboard, it would detonate at the preset depth.[2]

The weapon's

W34 nuclear warhead was also used in several other weapons such as the Mark 45 torpedo and Mk 105 Hotpoint. An Anglicanised version, codenamed "Peter", was used as the primary for the thermonuclear Yellow Sun weapon, and with the codename Python in the American B28 nuclear bomb
