LRALT


American air-launched target rocket. Air-launched anti-ballistic missile target composed of two surplus SR19 states in tandem.

The LRALT program was managed by the Missile Defense Agency Targets and Countermeasures Directorate and developed for MDA by the US Air Force Space and Missile Systems Center and L3/Coleman Aerospace Corp. LRALT is based on two Minuteman II second stages taken from deactivated assets. The delivery system is air-extracted from a C-17 for launch on any azimuth. LRALT was developed as a target for realistic testing of the Ballistic Missile Defense System using air-launch as a method to relieve the test constraints imposed by fixed ground launch sites.
