PACIFIC OCEAN (Sept. 28, 2023) U.S. Navy Capt. Bill Dull, Deputy Branch Head for Strategic Systems Program's (SSP) Weapons, Systems, Operation, Evaluation and Training delivers a presentation on the facets of SSP's submarine-based flight-testing program to distinguished visitors and guests aboard the Arleigh Burke-class guided-missile destroyer USS Halsey (DDG 97) off the coast of San Diego, California, Wednesday. USS Halsey participated as a support vessel in the Demonstration and Shakedown Operation (DASO 32) for the Ohio-class ballistic missile submarine USS Louisiana (SSBN 743). The primary objective of DASO is to evaluate and demonstrate the readiness of the SSBN’s Strategic Weapon System (SWS) and crew before operational deployment following the submarine’s engineered refueling overhaul. DASO-32 is the final DASO conducted by an Ohio-class SSBN coming out of engineering refueling overhaul (ERO), marking the completion of all post-ERO DASOs for the Ohio-class SSBNs. The Trident II D5LE strategic weapon system is the system that will provide the initial SWS capability for the Columbia-class SSBN.
