Helicopter Mine Countermeasures Squadron 15 (HM-15) is a US Navy helicopter squadron established in 1987 and based at NS 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 also at NS Norfolk, VA. This patch shows the BLACKHAWK (their mascot) carrying a MK-50 Series(?) in it’s talons and does not come with velcro attached.
