Navy Test-Fires Trident II D5 Sub-Launched Nuclear Weapons

The Navy test-fired two unarmed Trident II D5 nuclear missiles March 26, as part of an effort to assess various upgrades and sustain an undersea nuclear attack option amid a quickly-changing threat landscape, service officials said.
The weapons were fired off the coast of Southern California from the USS Nebraska, a nuclear-armed ballistic missile submarine.
