The NOTS-EV-1 Pilot, better known as NOTSNIK (pronounced notsnik a play on "sputnik") was an expendable launch system and anti-satellite weapon developed by the United States Navy's United States Naval Ordnance Test Station (NOTS).[2] NOTSNIK began as an in-house project using available NOTS funds. The Advanced Research Projects Agency later supplied some funds for the program.[3] The program involved creating transistorized sensors to detect nuclear explosions from the Operation Argus tests. Ten were launched during July and August 1958, all of which failed. It was the first air-launched rocket to be used for an orbital launch attempt; however, none was recorded as having reached orbit. Following the third orbital launch attempt a NOTS engineer at the tracking station in Christchurch, New Zealand reported receiving a weak signal from the spacecraft;[4] This was never confirmed,[5] and the launches were not catalogued as having reached orbit.[6] The Pilot rocket was part of Project Pilot.[7]
