Designed to replace the venerable Bell 
         Huey series , the S-70 had not yet the export success of them but 2000 
         Hawks were built by 1994.  
          
         The YUH-60 was the winner of the 1972 's US Army UTTAS program ( 
         Utility Tactical Transport Aircraft System ) against the Boeing Vertol 
         YUH-61 for a new helicopter that contemplate the Vietnam era lessons.
          
          
         Configured in more than 10 different versions for the US armed forces, 
         had became more famous every day since 1978 when the first unit was 
         given to the US Army.

         US Navy Seahawks 
          
         The Seahawks for the US Navy come in three versions, SH-60B, SH-60F,and 
         HH-60H.  
          
         The SH-60B was the first of the bunch and can be distinguished by its 
         surface search radar underneath the cockpit, between the wheels. Also 
         all SH60B's have a sonobouy launcher on the left side that looks like a 
         five by five set of tubes. SH60Bs are used off cruisers and destroyers 
         for antisubmarine warfare and surface search and surveillance.  
          
         The SH-60F is the next in line and is the carrier based version of the 
         Seahawk. It has a dipping sonar (unique in the Seahawk family), it is 
         used to find submarines. It is also the "slickest" of the group having 
         very little things sticking out of it. It has no surface search radar 
         or side mounted sonobouy launcher. It is most often confused with the B 
         model, not the H.  
          
         The HH-60H is the final version. It has the two sliding windows on the 
         left side. It also has the special HRSS nozzles on the exhaust to 
         reduce heat signature. Some times, the HH-60H can be seen with a nose 
         mounted FLIR ball and HELLFIRE missiles. It is used for Cargo, Combat 
         Search and Rescue, and other missions.  
          
         Currently the US Navy is buying the SH-60R (remanufactured SH-60B/F) 
         and CH-60S (new ones, now renamed the MH-60S Knighthawk) which will 
         eventually replace the three models.  
         US Air Force HH/MH-60G Pavehawks 
          
         There is (was) virtually no difference between the MH-60G Pave Hawk and 
         the HH-60G Pave Hawk with a few minor exceptions. The biggest 
         difference (and determining factor in the designation) is the command 
         that they were assigned to. The 10 MH-60G's were assigned to AF Special 
         Operations Command (AFSOC) and hence the "MH" designation for "multi 
         mission". The MH-60G's also had a different paint scheme -- a dark gray 
         similar to the other AFSOC aircraft like the MH-53J/L Pave Low and the 
         MC-130's. The remaining HH-60G's were assigned to rescue duties with 
         Air Combat Command (ACC) and painted woodland camouflage.  
         The other minor 
         differences are that the MH-60G's had "Sea Hawk" windows long before 
         the HH-60G's, the (former) MH-60G's all have rotor breaks, and they 
         have windshield washer reservoirs and motors. When the USAF had both 
         designations in service, there was only one Operator's Manual ("Dash 
         1") and it was for the "MH/HH-60G Pave Hawk". With the closing of the 
         only AFSOC MH-60G unit in the late 90's, the MH-60G's were transferred 
         to ACC, painted woodland camo, and redesignated HH-60Gs. The USAF 
         currently has no MH-60G Pave Hawks in service -- they are all now 
         HH-60G Pave Hawks... though that may change with the move of ALL 
         HH-60G's to AFSOC on October 2003.
