Direct proof of use
The SH-60 Seahawk family is directly documented in the 1990 Gulf War through U.S. Navy HH-60H strike-rescue and combat search-and-rescue activity during Operations Desert Shield and Desert Storm. Naval History and Heritage Command's Desert Storm overview identifies the conflict as the first combat operations for the HH-60H Seahawk strike-rescue helicopter.
A public archive record sourced to the U.S. National Archives shows an HH-60H Sea Hawk from Helicopter Combat Search and Rescue/Special Warfare Support Squadron 4 prepared for a search-and-rescue mission at the start of Operation Desert Storm. An official HSC-85 history also traces HCS-4 and HCS-5 to the HH-60H transition and records combat search-and-rescue strip alert during Operations Desert Shield and Desert Storm.

Combat chronology
HCS-4 and HCS-5 had transitioned to the Sikorsky HH-60H before the war, combining their special-operations support lineage with the combat search-and-rescue mission. HSC-85's official history says both squadrons transitioned to the HH-60H, known unofficially as the Rescue Hawk, as they continued special operations support and assumed the combat search-and-rescue mission.
During Desert Shield and Desert Storm, the HH-60H provided a rescue and force-protection role rather than a documented strike role in the sources used here. The HSC-85 history specifically describes combat search-and-rescue strip alert for the Desert Shield and Desert Storm period, and the NARA-derived photo record ties an HCS-4 HH-60H to a search-and-rescue mission at the start of Desert Storm.
Together, the official Navy history and archive record support treating the Gulf War entry as documented U.S. Navy Seahawk use, with the clearest mission evidence centered on HH-60H rescue support.

Operational role
The documented user was the U.S. Navy on the coalition side. The most specific variant in the conflict-use sources is the HH-60H Seahawk, operated by specialized Navy reserve squadrons for strike rescue, combat search and rescue, and special-operations support.
The cited sources support deployment, alert posture, and search-and-rescue mission use in the Desert Shield and Desert Storm theater. They do not, by themselves, support a broader claim that SH-60-family helicopters fired weapons in the Gulf War, so this record keeps the role to force protection, personnel recovery, and maritime support.
