Flight test vehicle for Exoatmospheric Re-Entry Interceptor Subsystem, an anti-ballistic missile hit-to-kill interceptor warhead. The ERIS vehicle itself consisted of surplus Minuteman ICBM second and third stages. Lockheed was awarded a five year contract in November 1985 worth at that time $ 490 million that included integration of the rocket. Four test vehicles were built. First launch was made on 28 January 1991 from Kwajalein Atoll against an Aries sounding rocket. A second test on 13 March 1992 against a Minuteman I was considered successful enough that no further tests were planned. Further develoment of the technology was to be accomplished by the Orbital Sciences' Aries test vehicle with spectacularly poor results.
