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.
