Boar Atomic Rocket

Mk1 Boar naval nuclear weapon The Boar (Bureau of Ordnance’s Atomic Rocket) was an early-1950s USN attempt to enable carrier-borne single-engine propeller warplanes (and first-generation naval jets) to employ atomic weapons in a tactical anti-ship context. It was also envisioned for supporting amphibious landings. The Boar was completely unguided. The tail rocket was simply a very crude self-contained combustion chamber which burned for three seconds. The warhead was the 20kT W7, which was a uranium fission model (TX-7E fissile component). The US Navy also used the same W7 warhead in the Mk90 atomic depth charge.
