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 their detachment patch created for Det-2 on the USS PONCE. It says “QUAL’ED BUT NOT TRUSTED” at the bottom.
