Helicopter Mine Countermeasures Squadron 15 (HM-15) is a USN helicopter squadron established in 1987 and based at NAS Norfolk, VA. 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 NAS Norfolk, VA. This is the ‘DET3A’ version of their squadron patch by one of their ‘Korean’ suppliers, has the red/blue “swirls” around the Hawk, and does not come with velcro attached.
