The U.S. Navy's Trident II D5 Missile Reaches 150 Flights

June 9, 2014

The U.S. Navy's Trident II D5 Fleet Ballistic Missile, built by Lockheed Martin, has achieved 150 successful test flights, setting a new reliability record for large ballistic missiles.

The Navy launched two unarmed missiles June 2 in the Atlantic Ocean from a submerged Ohio-class submarine, marking the 149th and 150th successful test flights of the missile since design completion in 1989.

According to a release from the company, the test flights were part of a demonstration and shakedown operation, which the Navy uses to certify a submarine for deployment following an overhaul. The missiles were converted into test configurations with kits containing range safety devices and flight telemetry instrumentation.

The operation included the first flight of two modernized avionics subsystems that control key missile functions during flight. The subsystems were updated under the D5 Life Extension program, which incorporates current technologies into the missile's electronics to cost-effectively prolong the service life of the D5 missile design on current and next-generation submarine platforms.

"The success of this Life Extension flight is a tribute to the dedication and innovation of the entire government and industry team," said Doug White, Fleet Ballistic Missile programs vice president, Lockheed Martin Space Systems Company. "In partnership with Navy Strategic Systems Programs, we set the bar high to provide a credible, reliable and affordable sea-based strategic deterrent for the nation."

Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company.
