The USS Denver (LPD-9) was an Austin-class amphibious transport dock built for the United States Navy. Laid down on July 7, 1964, at Lockheed Shipbuilding and Construction Company in Seattle, Washington, she was launched on January 23, 1965, and commissioned on October 26, 1968. As an Austin-class vessel, Denver was designed to support amphibious assault and transport operations, featuring a robust hull and capabilities suitable for a variety of missions. Over her 46 years of service, Denver played a significant role in various military and humanitarian operations. She was actively involved in the Vietnam War, notably participating in Operation Frequent Wind in April 1975, which was the evacuation of Saigon. She contributed to combat actions, including attacks on North Vietnamese barges in 1972, and was a key asset in maritime interdiction and support operations in the Asia-Pacific region. In 1970, Denver was dispatched to intercept the mutinous SS Columbia Eagle, highlighting her role in maritime security. In addition to combat and evacuation missions, Denver also engaged in humanitarian efforts. She rendered aid to Taiwan following Typhoon Morakot in 2009, supporting disaster relief by airlifting supplies and heavy equipment. The vessel also participated in recovery efforts after the 2009 Sumatran earthquakes and supported operations in Somalia in 1993. Denver continued her service with deployments throughout Southeast Asia, including a patrol of the western Pacific in 2011, and endured repairs after boiler damage during a 2012 patrol. Her long service culminated in her decommissioning at Joint Base Pearl Harbor–Hickam on August 14, 2014. She was the oldest active warship in the U.S. Navy at that time, and one of the last ships with Vietnam War service. On July 22, 2022, Denver was sunk during a multinational RIMPAC 2022 exercise, participating in a sinking exercise involving advanced missile and gunfire, sinking her in deep waters off Hawaii.
