Draper Lab gets $131.1 million contract to upgrade the guidance systems on the Trident II D5 missile. (Feb 2/10)
The year that the Trident II D5 ballistic missile was first deployed, 1990, saw the beginning of the end of the missile’s primary mission – to deter a first nuclear strike by the Soviet Union.
Nuclear tipped missiles were first deployed on board US submarines in the 1960s at the height of the Cold War to deter a Soviet first strike. The deterrence theorists argued that, unlike their land-based cousins, submarine-based nuclear weapons couldn’t be taken out by a surprise first strike by the Soviet Union because the submarines were nearly impossible to locate and target. Thus, Soviet leaders could not hope to destroy the weapons before they could be launched against Soviet territory.
But by the time the latest version of the submarine-launched ballistic missile was deployed, the existence of the Soviet Union itself was in doubt. The previous year, the Soviet’s Eastern European client states began to fall, symbolized by the destruction of the Berlin Wall. The Soviet Union itself began to crumble with various Soviet republics rebelling against the central government in 1990. Then, in 1991, a failed coup attempt against Soviet reformer Mikhail Gorbachev brought to power Boris Yeltsin, who promptly dissolved the Soviet Union…

The end of the Soviet Union and the easing of the Soviet first strike threat did not end the need for a nuclear deterrent. The unpredictability of a nuclear-armed Russia and the threat of nuclear-armed rogue states and non-state actors necessitated US retention of a nuclear deterrent capability.
To ensure the US deterrent capability was maintained at peak readiness, the US Navy undertook a program in 2002 to replace aging components of the Trident II D5 missile called the D5 Life Extension (LE) Program. The program involves updating the missile’s electronics, guidance and reentry systems.
The Trident II D5 LE Program is intended to extend the service life of the weapon system until 2042 to match the hull life of the Ohio-class submarine. Under the program, 108 additional missiles [pdf] are being purchased in order to meet long-term inventory requirements associated with the LE of the Ohio-class nuclear submarines.
The prime contractor [pdf] for the Trident II D5 program, as well as all of the US submarine-launched ballistic programs since the first generation Polaris missile, is Lockheed Martin.

Unless otherwise noted, the US Navy’s Strategic Systems Programs in Arlington, VA issued the contracts.
Feb 2/10: Charles Stark Draper Laboratory in Cambridge, MA received a $131.1 million cost-plus-incentive-fee contract for the Trident II D5 MK6 life extension guidance system. This contract is to procure long lead materials and circuit card assemblies to support the delivery of 20 MK6LE guidance systems.
Draper Lab will perform the work in Bloomington, MN (59%); Clearwater, FL (22%); Cambridge, MA (15%); and Pittsfield, MA (4%), and expects to complete it by June 30/15. This contract is a sole source acquisition by the US Navy’s Strategic Systems Programs in Arlington, VA (N00030-10-C-0015).
Dec 28/09: Lockheed Martin announces that the US Navy conducted a test flight of a Trident II D5 missile from the USS Alaska (SSBN 732) in the Atlantic Ocean. The test, conducted Dec 19/09, marks the 130th successful test flight of the Trident II D5 missile since 1989.
The Navy launched the missile as part of a Demonstration and Shakedown Operation (DASO) to certify USS Alaska for deployment, following a shipyard overhaul period. For the test, a missile was converted into a test configuration using a test missile kit produced by Lockheed Martin that contained range safety devices and flight telemetry instrumentation.
Dec 14/09: General Dynamics Advanced Information Systems received a contract from Charles Stark Draper Laboratory to produce integrated circuits for the Trident II D5 submarine-launched ballistic missile program. This is a 3-year contract with a total potential value of $110 million including the pre-priced options.
The contract is part of the Trident II D5 LE program. General Dynamics is also providing circuit card assemblies for the Trident II D5 missile and guidance systems. The principle subcontractor to General Dynamics for the wafer foundry services is Honeywell International and work will be performed at its Plymouth, MN facility.
Dec 8/09: Lockheed Martin Space Systems in Sunnyvale, CA received a not-to-exceed $851 million cost-plus-incentive-fee/ cost-plus-fixed-fee contract to provide support for production of Trident II D-5 ballistic missiles as well as maintenance of deployed D-5 and C-4 missiles.
Under the contract, Lockheed Martin is providing D5 missile hardware production support and reentry system hardware, as well as operations and maintenance to support the readiness and reliability of missile systems deployed aboard the US Navy’s Trident II Ohio-class SSBNs. The contract also continues the D5 LE effort, which updates electronic components to support the extended service life of the Ohio-class SSBNs
Mature D5 production efforts will transition to a fixed-price-incentive contract in fiscal year 2011. Lockheed Martin expects to complete the work by Dec 30/13. Contract funds in the amount of $284,965 will expire at the end the current fiscal year. The contract was not competitively procured (N00030-10-C-0100).
Dec 4/09: Charles Stark Draper Laboratory in Cambridge, MA received a $133.3 million modification (#P00003) under a previously awarded cost-plus-incentive-fee, cost-plus-fixed-fee contract (N00030-09-C-0008) for the Trident II D5 guidance system tactical engineering support and guidance applications program.
Specific tasks include:
- provide tactical engineering support;
- provide Mk6 LE field support services;
- develop a strategic guidance application program;
- develop a GPS receiver design approach;
- provide support for the Extended Navy Test Bed (ENTB) and ENTB derivative reentry body experiments (ENTB [pdf] is a special Trident reentry body used to test performance of the missile’s reentry vehicle guidance using GPS); and
- assess maintaining the accuracy of the existing reentry systems.
The contract modification increases the total contract value to $290.7 million. Work will be performed in Cambridge, MA (73%); Pittsfield, MA (21%); El Segundo, CA (4%); Clearwater, FL (1%); and Andover, MA (1%). Work is expected to be complete by Sept 30/11.
Dec 4/09: Charles Stark Draper Laboratory in Cambridge, MA received a $109.7 million modification (#P00009) under a previously awarded cost-plus-incentive-fee, cost-plus-fixed-fee contract (N00030-08-C-0010) for repair of the Trident II D5 Mk 6 LE guidance system.
Specific tasks include guidance system repair and the delivery of Mk6 LE pre-production units to support 3 planned proofing test missile flights. The modification increases the total contract value to $547.6 million. Work will be performed in Cambridge, MA (82%) and Pittsfield, MA (18%) and is expected to be complete by Sept 30/12.
The Mk6 LE guidance system is a replacement for the aging Mk6 guidance system, which used 1980s technology that isn’t in production any more. The Next Generation Guidance (NGG) program aims to develop the Mk6 LE as a modern replacement that can achieve the same or better performance as the guidance systems that are breaking down. This requires development of precision instruments, sensors, and radiation hardened architectures, in order to adapt the underlying commercial technologies for use in a must-not-malfunction nuclear weapons system.
