"W41 was the designation of an American nuclear warhead, which was investigated during the late 1950s. Intended for use in the SM-64 Navajo cruise missile, the program was cancelled in 1957. The program was brief, considered at the same time as the TX-29, WX-15-X1 and XW-21 warheads. All were eventually replaced as the proposed Navajo warhead by the 39. The W41 was an adaptation of the B41 (Mk-41) thermonuclear bomb which was produced in large numbers and served in stockpile for 15 years."@en . . "yes"@en . "W41"@en . . . . "0"^^ . .
