US ballistic missile submarine successfully tests Trident II D5 Missile

United States Ohio-class ballistic missile submarine USS Nebraska (SSBN 739) along with the US Navy Strategic Systems Programs (SSP) conducted successful test flights of two Trident II D5 Missiles in the Pacific Test Range off the coast of Southern California on March 26, the US Navy said.

Trident II D5 Missiles launched were unarmed.

“The missiles were launched as a double mission test and were the key element of DASO 28, which marked the 166th and 167th successful test flights of the Trident II D5 missile since its introduction to the Fleet in 1989,” the US Navy said.

“The primary objective of the DASO (Demonstration and Shakedown Operation) is to evaluate and demonstrate the readiness of the SSBN’s strategic weapon system and crew before operational deployment following midlife refueling overhaul,” it added.

SSP Deputy Director Captain Mark Behning said the successful completion of DASO 28 was not only an important milestone in USS Nebraska’s return to service, but also an important demonstration of the reliable and credible sea-based leg of the US nuclear deterrent triad.

Assigned to Submarine Group 9, USS Nebraska is one of eight ballistic-missile submarines homeported at Naval Base Kitsap-Bangor, Washington.
