The Bombardment Aircraft Rocket, also known as BOAR, the Bureau of Ordnance Aircraft Rocket, and officially as the 30.5-Inch Rocket, Mark 1, Mod 0, was an unguided air-to-surface rocket developed by the United States Navy's Naval Ordnance Test Station during the 1950s. Intended to provide a standoff nuclear capability for carrier-based aircraft, the rocket entered operational service in 1956, remaining in service until 1963.
==Design and development==
Following a specification developed during 1951,〔Babcock 2008, p.321-324〕 the development of the BOAR rocket was started in 1952 at the Naval Ordnance Test Station (NOTS), located at China Lake, California.〔Parsch 2003〕 The project was intended to provide a simple means of extending the stand-off range of nuclear weapons delivered using the toss bombing technique, as some slower aircraft still faced marginal escape conditions when delivering ordinary gravity bombs even with the use of this technique.〔
The rocket that emerged from the development process used a single, solid-fueled rocket motor mated to the W7 nuclear weapon, which had a yield of .〔Polmar 2001, p.527.〕 This provided a stand-off range of when released in a steep climb, the aircraft then completing the toss-bombing pullout to escape the blast; the rocket, lacking guidance, would follow a ballistic trajectory to impact following rocket burnout.〔
