The Ohio-class ballistic missile submarine USS Louisiana (SSBN 743) launched an unarmed life-extended Trident II (D5LE) missile on 27 September on the Western Test Range off the coast of San Diego, California for a scheduled missile test flight, the US Navy (USN) confirmed on 28 September.

This test marked the 191st successful Trident II (D5 & D5LE) strategic weapon system (SWS) missile launch since starting operations in 1989, USN officials said.

The tests help sustain the weapons system and ensure the United States sea-based strategic deterrence capability through 2084, Vice Admiral Johnny Wolfe Jr, the director for Strategic Systems Programs, said in a statement.

The navy purchased over 530 D5 missiles to support the Trident fleet, the Congressional Research Service (CRS) noted in a report released in May on US strategic forces.
