a Hawker Hunter. Iraqi Hunter pilots were officially credited for shooting down a further four Israeli aircraft, and another one was credited to anti-aircraft guns. Thanks to its Hunters and MiG-21s, the IrAF was successfully able to defend its bases in western Iraq from additional Israeli attacks. 1970s and the Yom Kippur War Throughout this decade, the IQAF grew in size and capability, as the 20 year Treaty of friendship with the USSR signed in 1971 brought large numbers of relatively modern fighter aircraft to the air force. The Iraqi government was never satisfied with the Soviets alone supplying them, and while they were purchasing modern fighters like the MiG-21 and the Sukhoi Su-20, they began persuading the French to sell Mirage F1s fighters (which were bought) and later Jaguars (which were however never ordered). Before the Yom Kippur War, the IQAF sent 12 Hawker Hunters to Egypt where they stayed to fight; only 1 survived the war. The IQAF first received their Sukhoi Su-7s in 1968; they were originally stationed in Syria. Aircraft deployed to Syria suffered heavy losses due to Israeli aircraft and SAMs. In addition, they were hit with friendly fire from Syrian SAMs. A planned attack on the 8th of October was canceled due to these heavy losses as well as disagreements with the Syrian government. Eventually, all aircraft besides several Sukhoi Su-7s were withdrawn from bases in Syria. During the war in October 1973, the first air strike against Israeli bases in Sinai was composed of Iraqi planes; they hit artillery sites and Israeli tanks, and they also claimed to have destroyed 21 Israeli fighters in air combat. Shortly after the war, the IQAF ordered 14 Tupolev Tu-22Bs and two Tu-22Us from the USSR as well as Raduga Kh-22 missiles and by 1975, 10 Tu-22Bs and 2 Tu-22Us were delivered. The 1970s also saw a series of fierce Kurdish uprisings in the north of the country against Iraq. With the help of the Shah of Iran, the Kurds received arms and supplies including modern SAMs as well as some Iranian soldiers. The IQAF suffered heavy casualties fighting the Kurds, so they began using their new Tu-22s in combat against them (using 3 tonne bombs from high altitude to avoid the Iranian HAWK SAM batteries that the Shah had set up near the Iraqi border to cover the Kurdish insurgents) as they were able to avoid
