Lockheed Martin gets Trident II contract
16 December 1999
The U.S. Navy recently awarded the Lockheed Martin Missiles & Space Strategic Missile Programs a $589 million contract for the follow-on production of 12 Trident II D5 missiles, deployed system support and related service efforts.
This contract is one of several scheduled to be awarded to LMMS until 2005 for production of D5 missiles for retrofit into four of the Ohio-class submarines stationed at the navy submarine base in Bangor in Washington State.
Missile production will begin in 2000, with an expected delivery to the Navy in 2002. Since initial production began in 1987, the U.S. Navy has purchased 372 Trident II D5 missiles.
Recently, two D5 missiles were successfully launched in a test conducted at the Eastern Test Range off the Florida coast. These two missiles represented the 86th and 87th consecutive successful launch of the Trident II D5 missile and continue the string of successful test launches that began in December 1989.
Ohio Class Submarine
These missile assets are to support deployments aboard the Ohio-class submarines USS Henry M. Jackson (SSBN-730), USS Alabama (SSBN-731), USS Alaska (SSBN-732), and USS Nevada (SSBN-734), which are to begin conversion to carry Trident II missiles starting in 2000. These submarines currently carry Trident I C4 missiles.
The Strategic Arms Limitation Treaty, (SALT), limits the number of re-entry vehicles to eight per missile, but Trident II is capable of carrying up to 12 MIRVs, multiple independent re-entry vehicles, each with a yield of 100 kilotons. The Circular Error Probable, i.e. the radius of the circle within which half the strikes will impact, is less than 150 metres.
An improved inertial navigation/global positioning system provides the higher accuracy navigation and guidance required for the development of a conventional (non-nuclear warhead) version of Trident. The conventional version of Trident will be capable of delivering a kinetic energy warhead to targets such as underground missile silos.
The Navy selected Lockheed Martin Missiles & Space as its prime missile contractor in 1956. Since then, the FBM team has produced the Polaris (A1), Polaris (A2), Polaris (A3), Poseidon (C3), Trident I (C4) and the Trident II (D5) missile.
