Those 'Hawks are not SH-60s, nor are they MH-60Rs, instead they're MH-60S Knighthawks, which is a navalized derivative of the Army's UH-60L Blackhawk airframe, blended with the folding main rotor blades of the SH-60 Series, the T700GE-400 engines, and folding tail rotor pylon. Also, the tail wheel of the UH-60 airframe was moved forward from its original location in order to allow the tail to fold. Plus, the MH-60S is compatible with the RAST System used by the Navy,'s Cruisers, and Destroyers, which allows an assist to help the aircraft land on the flight deck, when the weather doesn't allow unassisted landings. Oh, and one more feature from the Seahawk that was added to the Knighthawk, is a Rotor Brake. Another way to tell the two apart from each other, is to look for larger cabin doors, and Infrared Suppressors on the exhaust of the Knighthawk. The Strikehawk has the same cabin as the SH-60B/F, and the same dual wheel tail wheel, along with no suppressed exhaust, and smaller cabin doors.
