Bomb, 750 lb Fire, Mk 77 Mod 1
Description
The 500 lb Fire Bomb Mk 77 Mod 1 is a 75 gallon capacity bomb obtained by modifying Fire Bomb Mk 77 Mod 0. The modification of Bomb Mk 77 Mod 0 consists of cutting approximately two inches off the nose and tail body sections and approximately 12 inches from each end of the center section. These modified sections are welded together to give a 75 gallon capacity, 500 lb bomb.
Two suspension lugs are mounted on the body 14 inches apart. Identifying nomenclature is stenciled in red letters on the modified bomb body.
Two gasket sealed filler holes are located on the upper bomb surface.
Hazardous Components
Igniters and fuzes are used in the nose and tail of Fire Bomb Mk 77 Mod 1. Three igniters, M15, M16, and M23, may be used. The bomb is designed for primary use of Igniter M23 with Fuze M173 in both the nose and tail. Adapters are furnished with the bomb so that Igniter M15 with Fuze M157 can be used in the nose or tail of the bomb. Igniter M16 with Fuze M157 can be used in the tail of the bomb only, because the nose cone will not accommodate this larger igniter.
Filler is 75 gallons of napalm.
