The Sikorsky MH-53 is a variant of the CH-53 except for a few particulars such as fuels and weights. It combines the power of the 3-engined CH-53E with the minesweeping capabilities of the RH-53D and enables it to drag heavier minehunting sleds through rougher seas. It also has upgraded adverse weather avionics allowing it to operate in the worst of conditions. This is the large, black, anniversary patch created that says “40 YEAR OF HEAVY METAL” and does come with velcro attached. The date at the bottom says DECEMBER 23 1981.
