Iran–Iraq War: The Islamic Republic of Iran Air Force mounts an attack on H-3 Airbase and destroys about 50 Iraqi aircraft.

The Iran–Iraq War was an armed conflict between Iran and Iraq that lasted from September 1980 to August 1988. Active hostilities began with the Iraqi invasion of Iran and lasted for nearly eight years, until the acceptance of United Nations Security Council Resolution 598 by both sides. Iraq's primary rationale for the attack against Iran cited the need to prevent Ruhollah Khomeini—who had spearheaded the Iranian revolution in 1979—from exporting the new Iranian ideology to Iraq. There were also fears among the Iraqi leadership of Saddam Hussein that Iran, a theocratic state with a population predominantly composed of Shia Muslims, would exploit sectarian tensions in Iraq by rallying Iraq's Shia majority against the Baʽathist government, which was officially secular but dominated by Sunni Muslims. Iraq also wished to replace Iran as the power player in the Persian Gulf, which was not seen as an achievable objective prior to the Islamic Revolution because of Pahlavi Iran's economic and military superiority as well as its close relationships with the United States and Israel.

The Islamic Republic of Iran Air Force is the aviation branch of the Islamic Republic of Iran Army. The present air force was created when the Imperial Iranian Air Force was renamed in 1979 following the Iranian Revolution. The IRIAF was heavily involved in the Iran–Iraq War, carrying out major operations like Operation Kaman 99, Operation Sultan 10, the H-3 airstrike, and the first attack on a nuclear reactor in history, Operation Scorch Sword.

The H-3 airstrike was a surprise air attack by the Iranian Air Force during the Iran–Iraq War on 4 April 1981 against the Iraqi Air Force's H-3 Air Base in western Iraq. The Iranians destroyed at least 48 Iraqi aircraft on the ground with no losses of their own. Based on the results achieved, it is considered one of the most successful raids in the history of aerial warfare.
