"From now on, every missile that we fly will be a D-5 life-extended missile with a new guidance subsystem and a new set of missile electronics.”

Although when most people think of the Trident life extension, they think of the missile, much of the work his office has been doing is on the shipboard systems, “which, I think, is much more complicated,” he said.

That work is upgrading fire control, communications and navigation systems and the launch tubes, he said."

"The admiral added that his office, “in cooperation with” the Energy Department, is working on life extension of the Tridents’ nuclear warheads, which also will arm the replacement submarines. And he is supervising tests of future missile launch tubes at ground test facilities at China Lake, Calif., and Cape Canaveral, Fla., that will enable production of the launch tubes in Columbia and Dreadnaught."

"Strategic Systems Program (SSP) Director Vice Adm. Terry Benedict said on Nov. 2 that “I’m very proud to report that at 0300 on Monday night SSP flew from Hawaii [Pacific Missile Range Facility] … the first conventional prompt strike missile for the United States Navy in the form factor that would eventually, could eventually be utilized if leadership chooses to do so in an Ohio-class tube. It’s a monumental achievement.”"
