W67 (nuclear warhead)
The W67 was an American thermonuclear warhead developed from June 1966 but then cancelled prior to any production or service use approximately 18 months later.[1]
Developed by Los Alamos,[2] the warhead was in the megaton range[3] and was to have a yield comparable to that of the W56.[4] It was housed in the Mark 17 reentry vehicle and one of the warhead's design goals was the highest maximum output temperature possible. Only one partial yield test of the warhead was performed before the warhead was cancelled in January 1968.Template:Sfn Hansen identifies this test as Crosstie Zara.Template:Sfn
The Mark 17 RV had a difficult development. The planned total RV and warhead weight was Script error: No such module "convert"., but by November 1966 it weighed Script error: No such module "convert". due to the higher than anticipated levels of hostile weapons effects protection needed. The actual warhead weight was Script error: No such module "convert"..[5]
After its cancellation, the W68 warhead was developed for Poseidon and the W62 warhead for Minuteman III.Template:Sfn
The W67 was briefly revived in 1970 for the CAFE (C-3 Alternative Front End) program for Poseidon. CAFE was a contingency program for in the event that MIRV warheads were banned and Poseidon needed to be fitted with a single warhead. Two W67 designs were examined and would use the Mark 1 Prime reentry body. Total warhead weight was Script error: No such module "convert"..[6]
