VP-21

Patrol Squadron 21 (VP-21) was a U.S. Navy patrol squadron established in 1943 during World War II. Originally equipped with PBM Mariner seaplanes, VP-21 conducted anti-submarine warfare, maritime patrol, and reconnaissance missions in the Atlantic and later in the Pacific theaters. The squadron played a vital role in protecting Allied convoys from German U-boats and participated in search and rescue operations. VP-21 continued its service during the early Cold War period, eventually being disestablished in 1969 after numerous redesignations and decades of distinguished operational history.
