Helicopter Mine Countermeasures Squadron Twelve (HM-12), known as the "Sea Dragons," was established by the United States Navy on April 1, 1971. As the Navy’s first dedicated airborne mine countermeasures (AMCM) squadron, HM-12 played a crucial role in developing and deploying helicopter-based mine-sweeping techniques, primarily using the CH-53 Sea Stallion helicopters. The unit provided vital mine-clearing support during operations such as the Vietnam War and later the Persian Gulf conflicts. HM-12 was instrumental in training personnel and establishing doctrine for modern mine countermeasures before its deactivation in 1994, with its legacy continued by successor squadrons.

Helicopter Mine Countermeasures Squadron 16 (HM-16) was a United States Navy helicopter squadron established in 1971. The unit specialized in airborne mine countermeasures (AMCM), utilizing the CH-53 Sea Stallion and later the MH-53E Sea Dragon helicopters to detect and neutralize naval mines. HM-16 played a key role in various operations, ensuring safe maritime passage for U.S. and allied vessels, particularly during conflicts and heightened tensions in strategic waterways. The squadron was based at Naval Air Station Norfolk, Virginia, until it was disestablished in 1994 as part of post-Cold War force reductions.
