Trident D-5 SLBM Maintenance: Rocket Motors, Guidance
Apr 06, 2006 04:22 EDT
Carried on SSBN-726 Ohio Class submarines, The Trident II D-5 is the US Navy’s submarine launched nuclear missile, with exceptional range for a sea-launched weapon and accuracy figures that rival or even exceed land-based ICBMs. These missiles are arguably the most important and effective component of the US nuclear deterrent, and they constitute Britain’s entire nuclear deterrent as well. They were first deployed in 1990, and are planned for continuous deployment to 2042.
The US Navy’s Strategic Systems Programs in Washington, DC and Lockheed Martin recently issued over $100 million in contracts related to the Trident II D-5 SLBMs, in order to maintain their propulsion and guidance systems.
Alliant Techsystems received a $76 million contract from Lockheed Martin to produce solid propulsion systems for all three stages of the U.S. Navy’s Trident II (D-5) missile. Under the terms of the contract, ATK will continue to supply Trident solid propulsion systems to Lockheed Martin Space Systems Company in Sunnyvale, CA through 2010. LMSS is the Trident II (D-5) Missile System’s Prime Contractor,
ATK has a 50-year history of producing solid propulsion systems for submarine-launched ballistic missiles, beginning with the original Polaris missile. The company’s solid rocket portfolio ranges from 3-inch diameter spin motors to the Space Shuttle’s Reusable Solid Rocket Motors (RSRM).
Meanwhile, the Charles Stark Draper Laboratory in Cambridge, MA received a $26.9 million cost-plus-incentive-fee contract to provide repair and recertification of MK-6 guidance systems, including pendulous integrating gyroscopic accelerometers, inertial measurement units, electronic assemblies, inertial measurement units electronics, repair parts, test equipment maintenance, and related hardware. Work will be performed in Cambridge, MA and is expected to be complete September 2006. The contract was not competitively procured by the US Navy’s Strategic Systems Programs in Arlington, VA (N000-30-06-C-0002).
DID has covered work on the aging MK-6 guidance systems before, including key subcontracters to Draper’s efforts. We have also noted the efforts underway to develop a modernized Mk6 LE guidance system that dispenses with obsolete 1980s era electronics, and how that fits into overall Trident II modernization activities.
