===1965 Indo-Pakistani War: Eastern Theater===
The air forces of both countries launched attacks against each other's bases in the eastern theater as soon as hostilities commenced in September 1965. The IAF bombed airfields and airstrips located in East Pakistan (at [[Chittagong]], [[Dhaka]], [[Lalmunirhat Airport]], and [[Jessore (city)|Jessore]]), while the PAF managed to launch two celebrated raids on the Indian Air Force base at [[Kalaikunda Air Force Station|Kalaikunda]], near [[Kharagpur]], in [[West Bengal]].<ref>Gp Capt NA Moitra VM</ref> The PAF raids, a five-plane strike which had achieved total surprise, was followed up by a four-plane attack, which was opposed by Indian Interceptors, took place on 7 September, destroying several [[English Electric Canberra]] bombers and [[Vampire|de Havilland Vampire]] aircraft on the ground,<ref>* [http://www.bharat-rakshak.com/IAF/History/1965war/Appendix2] {{Webarchive|url=https://archive.today/20130117205845/http://www.bharat-rakshak.com/IAF/History/1965war/Appendix2|date=17 January 2022}}</ref> while the IAF claimed 2 aerial kills (Pakistani sources record 1 F-86 lost).

[[English Electric Canberra|Canberra]] bombers struck [[Tejgaon Thana|Tejgaon]] repeatedly in the early hours of 4 December. The PAF No. 14 operated only [[Canadair Sabre|Sabres]], which lacked night fighting capability, so the bombers were opposed only by the guns of the Pakistani light ack-ack regiment.  IAF Hunters attacked Chittagong in the morning and [[Narayangunj]] fuel depots in the afternoon. Pakistani sources claim IAF lost two Canberras over Chittagong.<ref name="Salik, Siddiq p134">Salik, Siddiq, "Witness to Surrender" p134</ref> Tejgaon was repeatedly attacked by [[Hawker Hunter|Hunters]] of the [[No. 7 Squadron, Indian Air Force|No. 7]], and Squadrons No. 14, No. 17, and No. 37, [[Su-7]]s (No. 221 Squadron), and [[MiG-21]]s (No. 28 Squadron) on throughout the day. PAF was on full alert and Sabres flew Combat Air Patrols, resulting in several dogfights with Indian jets. The first daytime raids were flown by Hunters of No. 17 Squadron, and these were given top cover by four MiG-21s from No.28 Squadron. No. 14 Squadron also struck [[Kurmitola]] AFB, hitting the hangars and other installations with rockets. [[Mikoyan-Gurevich MiG-21|MiGs]] from 28 Squadron struck Tejgaon in the afternoon, destroying a [[De Havilland Canada DHC-6 Twin Otter|Twin otter]] on the ground.

PAF lost two Sabres in dog fights over Dhaka - to IAF Hunters striking Kurmitola. Wing Commander S. M. Ahmed and Flight Lt. Saeed [[ejection seat|ejected]] safely over the village of Ghazipur, but were not found by search parties. They were listed as "missing" for the duration of the war and then assumed killed by a hostile local populace.{{Citation needed|date=May 2022}} Wing Commander Nadrinder Chatrath of No 17 Squadron and Flight Officer Harish Masand each are credited with a Sabre kill. Squadron Leader K.D. Mehra of IAF No. 14 squadron was shot down by a Sabre. Later in the day PAF Flight officer Sajjad Noor was shot down by IAF NO 14 Squadron Leader Sundaresan, who lost his wingman when PAF Squadron Leader Dilawar Hussain shot down the Hunter of Flight Lt K. C. Tremenhere during the same dogfight.  Flight Lt. K. C. Tremenhere and Sajjad Noor ejected safely, and both were rescued and Tremenhere became a POW.<ref>Mohan, P.V.S.

PAF had flown Thirty two operational sorties against IAF incursions on 4 December, expending 30,000 rounds of ammunition, while the ground-based weapons had fired 70,000 rounds on the same day, the highest expenditure per day per aircraft of ammunition in the history of the PAF. Pakistani authorities claimed between 10 and 12 IAF planes were destroyed, and took measures to conserve ammunition in anticipation of a long war.<ref name="Salik, Siddiq p134"/> IAF claimed five Sabres shot down and another three destroyed on the ground. India's only aircraft carrier INS ''Vikrant'' (with its Sea Hawk fighter bombers and Breguet Alize ASW aircraft) mounted attacks against the civilian airport at Cox's Bazar and Chittagong Harbor.

IAF focus shifted on supporting the Mitro Bahini advance following the grounding of PAF after 7 December 1971. [[Folland Gnat|Gnat]] squadrons, previously employed in flying combat air patrols over IAF bases, now began attacking targets inside Pakistani territory along other IAF squadrons. The IAF flew interdiction missions for the remainder of the war, shooting up ammunition dumps and other fixed installations. Gnats and Sukhoi Su-7s flew many missions in support of army units as they moved swiftly towards Dhaka, delivering ordnance (such as iron bombs) to take out enemy bunkers which occasionally posed an obstacle to the advancing infantry. Canberras repeatedly struck Jessore, forcing the enemy to abandon this strategic city. The IAF also bombed other airfields, including the abandoned World War II airfields of [[Comilla]], [[Lal Munir Hat]], and [[Shamsher Nagar]] throughout the war, denying their use to PAF planes that may be moved by road, as well as to any external aerial reinforcement. {{INS|Vikrant|1961|6}}, the [[Indian Navy|Navy's]] sole aircraft carrier, periodically sent [[Hawker Sea Hawk|Sea Hawks]] to bomb the [[Chittagong]] harbor and airport throughout the war, while also sent bombing missions to [[Cox's Bazar]], [[Barisal]], Khulna and Mongla ports, and to Chandpur and other Pakistani positions between 7–14 December 1971.
