The NOTS-EV-1 Pilot, also known as NOTSNIK was an expendable launch system and anti-satellite weapon developed by the United States Navy's United States Naval Ordnance Test Station (NOTS). 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 first and third orbital launch attempts, a tracking station in New Zealand reported receiving weak signals from the spacecraft, however this was never confirmed, and the launches were not catalogued as having reached orbit. The Pilot rocket was part of Project Pilot.
