The British Atomic Bomb existed in three different variants :
WE177 B - introduced in 1966 by RAF units, dropped by parachute and planned for use against enemy airfields.
WE177 A - planned for the Royal Navy, introduced in 1969, planned for use as an anti-submarine depth charge. The size of the loadout was variable, as was the detonation time setting.
WE177 C - introduced in 1973, a smaller version of the above to meet NATO size restrictions on nuclear weapons.
The WE177 development programme was terminated in 1995.
