PACIFIC OCEAN (Sept. 28, 2023) - U.S. Navy Sailors stand watch in the bridge aboard the Ohio-class ballistic missile submarine USS Louisiana (SSBN 743) Demonstration and Shakedown Operation-32 (DASO-32). DASO 32 is the last 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. The Trident II D5LE strategic weapon system is the system that will provide the initial SWS capability for the Columbia-class SSBN.
