Sunnyvale CA: The U.S. Navy supported the May 26 launch of a U.K. Royal Navy Trident II D5 Fleet Ballistic Missile (FBM) built by Lockheed Martin. The unarmed missile was launched from the submerged Royal Navy submarine HMS Victorious (UK SSBN 06) in the Atlantic Ocean.
The Trident II D5 missile now has achieved 127 consecutive successful test flights since 1989 – a record unmatched by any other large ballistic missile or space launch vehicle.
“This performance has been achieved in tests conducted by the U.S. Navy and the Royal Navy over the past two decades,” said Melanie A. Sloane, vice president of Fleet Ballistic Missile programs, Lockheed Martin Space Systems Company, the Trident missile prime contractor.
“The cooperation of both governments, supported by industry, provides a credible strategic deterrent.”
The test was part of a Demonstration and Shakedown Operation following an overhaul of the submarine. For the test, a missile was converted into a test configuration using a test missile kit produced by Lockheed Martin that contains range safety devices and flight telemetry instrumentation.
First deployed in 1990, the D5 missile is currently aboard U.S. Navy OHIO-class and Royal Navy VANGUARD-class submarines. The three-stage, solid-propellant, inertial-guided ballistic missile can travel a nominal range of 4,000 nautical miles and carries multiple independently targeted reentry vehicles.
