Sparoair

Sparoair was a family of air-launched sounding rockets developed by the United States Navy in the late 1950s and early 1960s.

Based on the Sparrow air-to-air missile, three versions of the rocket were developed;[1][2][3] all launches were from Point Mugu and although some were successful,[4][1][2][3] the system did not enter operational service.

[5][6] Propelled by two Sparrow rocket motors mounted in tandem,[7] the Sparoair could be launched from F3H (F-3) Demon and F4D (F-6) Skyray fighter aircraft, and was capable of lifting a 40 pounds (18 kg) payload to an apogee of 65 nautical miles (120 km; 75 mi).

[8][6] The Sparoair I was the original version of the rocket, launched using an ejection system and a lanyard for firing; after that proved unreliable in flight testing, the Sparoair II was developed that utilised a rail launch with ignition prior to release from the aircraft.

[5] The first Sparoair III was launched on 8 July 1965; it proved a partial failure as the second stage failed to ignite.
