Lockheed Martin And ATK Test New Propulsion Technologies For Navy Strategic Missiles
The U.S. Navy, Lockheed Martin and Alliant Techsystems have tested new propulsion technologies for strategic missiles atNaval Air Weapons Center China Lake, Calif. A static test fire was conducted of the Third-Stage Application Program-3 (TSAP-3) motor, a modified Trident II D5 motor that incorporates cost-saving technologies. The motor features a new low-cost, low-erosion ceramic rocket nozzle throat, a new low-cost, high-performance propellant, and a lighter weight motor case and insulator to increase missile range. "The Navy's Strategic Systems Programs organization never rests in seeking to improve upon an already excellent record of efficient, cost-effective performance," said Joe Woo, Strategic Missile Technologies program manager, Lockheed Martin Space Systems Company. "This test supports our customer by showing the potential of new technologies to increase motor performance while reducing cost." Lockheed Martin developed the ceramic throat for solid rocket motors under company-funded independent research and development. By withstanding the extreme heat of rocket exhaust, the ceramic throat increases thrust and can be fabricated at a lower cost than nozzle throats currently in use. ATK developed the new RDX-NEPE solid propellant for the TSAP-3 motor. This fuel provides performance comparable to the propellant currently used in Trident II D5 motors at a lower cost. All of the components and materials tested are applicable to first-, second- and third-stage motors for strategic and conventional ballistic missiles, including those for Prompt Global Strike missions. U.S. Navy Strategic Systems Programs awarded Lockheed Martin Space Systems Company, Sunnyvale, Calif., the Strategic Missile Technologies prime contract in 2004 to demonstrate alternative technologies for propulsion, controls, ordnance and electronics subsystems.
