I believe that the foreign ones and the Customs ones are all technically S-70's, which is just the Sikorsky designation.
The two main subdivisions of the helicopters are the UH-60 and the SH
The UH-60 is the main Army variant. There are a couple of variations, the original A, the up rated L and a medivac Q version. The MH
-60's and the HH
-60G's are based on this model. The Maple Hawk was a proposed Canadian version of the HH
-60G that lost to the EH
-60 is a naval version. It features a folding tail and rotor system. The SH60B is the original naval anti-sub version, the SH
-60F is equip with a dipping sonar and replaces Sea Kings on carriers for the anti-sub role. The HH
-60H is designed with seal team transport and insertion in mind. It has the same small doors that the SH
-60 has, The HH
-60J is the USCG rescue variant and is pretty similar.
There has also been flown a proposed CH
-60 for the navy. This combines the Army UH-60 cabin with the rotor system of the SH
-60. This is intended, if adopted, to replace the Ch-46 in the VERTEP role. This variant is unique among naval models since it retains the army tailwheel.
Also I forgot to mention that the forestry people in California have to "Firehawks" that are S-70's equipped with an internal tank system for firefighting.
You also have the HH
-60H with is the SH
-60 Airframe meant for
OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.
