B83 (nuclear weapon)

B83 gravity bombs have the highest yield of any deployed U.S. nuclear weapon. They are carried aboard B-52 and B-2 bombers, as well as tactical aircraft incuding the F-16 Fighting Falcon, F-18 Hornet and F-18 Super Hornet, and AV-8 Harrier. Called the "modern strategic bomb", it has a yield adjustable between the "low kiloton" range and 1.2 megatons.

The bomb can be dropped at high or low altitude, and has a Kevlar parachute that allows low-altitude delivery from a supersonic aircraft. It was the first U.S. nuclear weapon designed with insensitive high explosive and has a Category D permissive action link.
