NOTE: HCS-4 and HCS-5 combined to two, two-plane detachements. They flew 461 sorties lasting 750 hours combined.
They combined their forces with Saudi AB-212s, the Saudis flying daytime missions up to 125 miles out, and HH-60Hs flying nighttime missions using NVGs and up to 210 miles.
The HH-60Hs were armed with door mounted M60Ds.
Info from Internet:
The Navy also used the S-70B airframe as the basis for its own covert operations / CSAR variant, the "HH-60H Rescue Hawk".
Unlike its Army and Air Force counterparts, it does not have an inflight refueling probe, though it can be fitted with external tanks.

It does have:
countermeasures suite, including HIRSS exhaust suppressors, an AN/ALQ-144 disco light jammer, AN/ALE-47 chaff-flare dispensers, and an AN/APR-39A(XE)2 RWR
ESM gear in noticeable blisters on each side of the forward tailboom. This system is used to locate downed pilots
RAST gear to support SEAL commando operations off of frigates and other smaller vessels. The RAST gear is removeable and not always fitted
NVG compatible cockpit
external rescue hoist on the right side of the machine
7.62 millimeter M-60D machine gun was originally fitted on a pintle mount in each door (the HH-60H has doors on each side but no forward window in which to mount a gun), but these were upgraded to more potent GECAL 12.7 millimeter machine guns. Initial flight of the HH-60H prototype was on 17 August 1988, with initial service deliveries in 1989. A total of 45 Rescue Hawks were ordered.

Info from Internet:
A total of 150 SH-60Bs had been delivered by the mid-1990s against a total requirement of 260. During operations in the Persian Gulf from 1987, a total of 25 SH-60Bs were fitted with countermeasures and other enhancements under the "Middle East Force Modification (MEF-MOD)" program, which included:
provisions for two AN/ALQ-144A IR jammer - one aft of the main rotor and the other forward of the tail wheel
two Tracor AN/ALE-39 chaff/flare launchers on either side of the aft fuselage
front/tail/side mounted AN/ALQ-156 MAWS antennas (similar to EH-60A)
door-mounted M-60D 7.62 millimeter machine gun
Texas Instruments AN/TAS-6A FLIR, hung from a bungee cord in the crew cabin, plus stabilized binoculars. Seven other machines also carried an AN/AAS-38 externally mounted FLIR pod

The Seahawk served with distinction in the Gulf War, flying boarding parties to support blockade operations; flying mine patrols; performing CSAR operations, rescuing an F-16C and an AV-8B pilot; transporting SEAL teams on special operations; and providing defensive sensors for US Navy surface elements. Seahawks carried an oversized chaff round named an AIRBAC that was ejected from a sonobuoy tube, providing a heavy cloud of chaff to frustrate Iraqi antiship missiles, which actually did not turn out to be much of a threat.
Even before the Gulf War, a "Block I" SH-60B upgrade was underway, featuring avionics enhancements such as a GPS navigation receiver and dual MIL-STD 1553B digital avionics buses; provision for mounting a GECAL 50 12.7 millimeter machine gun; and support for the improved "Mark 50 Barracuda" torpedo, which can dive deeper and has a smarter seeker than the older Mark 46, and for the AGM-199B Mark 2 Mod 7 Penguin antiship missile. The left stub stores pylon was extended to allow carriage of an external fuel tank along with the traditional two stores. The right stub pylon could not be extended since it would get in the way of the rescue hoist.
