Northrop Grumman Corp. recently supported the successful test of the Minuteman
III Propulsion System Rocket Engine (PSRE) at NASA's White Sands
Testing Facility in Las Cruces, N.M.
PSRE is the liquid post-boost upper stage of the Minuteman III
intercontinental ballistic missile. This was a designated product
quality assurance (PQA) test, which is a full mission duty ground
static test conducted in NASA's altitude test cell. The PQA test is
performed to verify the quality of the PSRE after it is refurbished
by the PSRE life-extension program (LEP). This test represents the
last of seven PQA static tests for the PSRE LEP program.
PSRE LEP program, initiated in 2000, is managed under a joint
partnership between Northrop Grumman and the U.S. Air Force. Aerojet and Boeingalso support the program. The
program is responsible for refurbishing the entire Minuteman III
fleet of PSREs and extending its service life through 2030. Upon
completion of the program last month, 558 PSREs will have been
delivered to the Air Force.
