Northrop Grumman Supports Propulsion System Rocket Engine Test

Jul 10, 2013 (SPX)

Herndon VA - Northrop Grumman 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.

The PSRE is the liquid post-boost upper stage of the Minuteman III intercontinental ballistic missile (ICBM). 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.

"The entire ICBM team, including our Aerojet and Boeing teammates and the Air Force, celebrate the success of this program as it comes to an end with this final accomplishment," said Tony Spehar, Northrop Grumman vice president and program manager for the ICBM Prime Integration Contract.

"These PSRE tests have ensured the reliability of the nation's deployed Minuteman fleet."

The PSRE LEP program, initiated in 2000, is managed under a joint partnership between Northrop Grumman and the U.S. Air Force.

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.
