Marine Heavy Helicopter Squadron 463 (HMH-463), known as the "Pegasus," was first activated in 1944 during World War II to support operations in the Pacific Theater. Reactivated during the Vietnam War, HMH-463 became renowned for its heavy-lift capabilities, operating the CH-53 Sea Stallion helicopters to conduct troop transport, supply missions, and combat support. Over the decades, the squadron played a vital role in major conflicts and humanitarian missions, including Operations Desert Storm, Enduring Freedom, and Iraqi Freedom. After decades of distinguished service, HMH-463 was deactivated in 2022 as part of the Marine Corps’ force modernization efforts.
