Direct proof of use
The C-5 Galaxy is directly documented in the 1990 Gulf War through official Air Mobility Command and U.S. Air Force historical accounts of Operation Desert Shield and Operation Desert Storm. Air Mobility Command's C-5 chronology states that C-5s moved 84,385 passengers and 201,685 short tons of cargo to the Persian Gulf region during the deployment phase that ended on March 10, 1991.
Official AMC reporting also identifies the C-5 as one of the main strategic airlift aircraft in the campaign. Across Desert Shield and Desert Storm, C-5s flew 3,770 strategic airlift missions, and C-141 and C-5 aircraft together accounted for 361,147 tons, or 66 percent of the cargo airlifted in support of the Gulf War.

Timeline
The C-5's documented Gulf War use began during the August 1990 Desert Shield deployment. AMC reporting says the first Military Airlift Command mission arrived in Saudi Arabia on August 8, 1990, and that all airlift control elements were in place by the end of that day after being carried on C-141, C-5, and C-130 missions.
On August 29, 1990, a C-5A crashed after takeoff from Ramstein Air Base, Germany, while departing on a Desert Shield mission to Dhahran Air Base, Saudi Arabia. The chronology records the aircraft carrying rations, maintenance equipment, medical supplies, and other general cargo. On January 19, 1991, after Iraqi missile attacks on Israel, USTRANSCOM directed Military Airlift Command to deploy Patriot missile batteries; thirty C-5s and nine C-141s moved missiles, launchers, personnel, and related equipment to Israel.

Operational role
The source-backed Gulf War role was mobility and logistics, not direct attack. C-5 aircraft moved people and cargo into the Persian Gulf region, including outsized loads that matched the aircraft's heavy strategic airlift mission. AMC's chronology describes the C-5 as the U.S. Air Force's sole organic outsize airlifter before the C-17 became operational in 1993, which explains why the aircraft was central to heavy theater deployment.
The same chronology also records limits on C-5 availability during the campaign. C-5s flew at three times their normal rate during Desert Shield and Desert Storm, but maintenance delays and fleet readiness shortfalls kept the aircraft from meeting every outsize airlift requirement.

Operators and locations
The directly documented operator was the U.S. Air Force mobility system, then organized under Military Airlift Command and directed through USTRANSCOM tasking. The source-backed locations include Saudi Arabia, the Persian Gulf region, Ramstein Air Base in Germany, Dhahran Air Base in Saudi Arabia, and Ben Gurion International Airport in Israel.
These sources support cataloging the C-5 Galaxy on the coalition side of the 1990 Gulf War. They document U.S. C-5 use for strategic deployment, sustainment, and Patriot-related airlift, not Iraqi operation of the aircraft.
