The air battle of Mansoura was an air battle that took place during the Yom Kippur War between the Egyptian Air Force (EAF) and the Israeli Air Force (IAF) near the town of El Mansoura, in the Nile Delta. The Israeli air force launched air strikes on October 14 against the Egyptian air bases at Tanta and Mansoura. Israeli aircraft were spotted approaching from the Mediterranean Sea. The 104th Air Wing of the Egyptian air force scrambled its fighters, receiving additional reinforcements from other air bases. The air battle began at 15:15 and lasted 53 minutes. The Egyptian commander was Hosni Mubarak. According to Egyptian sources, multiple Israeli fighters were shot down; this is disputed by Israeli sources. Background The 104th Air Wing had three squadrons equipped with MiG-21MF fighters; two squadrons were stationed at Mansoura, tasked with interception and air defense, and the third was stationed at the Tanta air base to defend both air bases. The IAF had made several attacks on the Mansoura air base from October 6 onwards, but failed due to dense Egyptian SAM defenses. At dawn on October 14, when Egyptian forces made their advance towards the Sinai Mitla and Gedy Passes, the ground forces were given ground support by MiG-17s, Su-7s, Su-20s and Mirage III fighter bombers. These in turn were given fighter cover by the 104th's MiG-21s. Although the Egyptian offensive on October 14 was a failure and culminated in heavy losses, the IAF was determined to destroy the 104th Air Wing's capabilities. A massive air strike would be launched against air bases in Salihiya, Mansoura and Tanta. In the aftermath of the Six-Day War, when the EAF lost almost all its aircraft on the ground to an Israeli preemptive strike, the Egyptians constructed 500 concrete shelters on 20 major airbases to prevent the aircraft from being destroyed on the ground in a future conflict. Initial contact On October 14, when the Egyptians advanced from their bridgeheads along the Suez Canal, an Israeli air strike was expected to come against the Mansoura air base sooner or later, and consequently a number of MiG-21s were kept at full alert at the end of the runway with their pilots, ready for immediate take-off. As of 15:00, there was still no indication of an impending enemy attack. At 15:15, air observation posts on the Mediterranean Sea notified EAF command that 20 Phantoms were approaching in
