Helicopter Mine Countermeasures Squadron 15 (HM-15) is a United States Navy helicopter squadron established in 1987 and based at Naval Station Norfolk, Virginia. Nicknamed the “Blackhawks” and flying the MH-53E Sea Dragon, it is staffed by both active duty and reserve personnel. It is the sister squadron to HM-14, the “Vanguard”, based a half-mile away at Naval Station Norfolk, VA. This is one of their detachment patches (unsure which det), but says “World Famous Blackhawks Since 1987” (along the top) and “Once a Blackhawk, Always a Blackhawk” (along the bottom) and does not have velcro attached.
