[3][4] Work on the second strand of development was carried out in parallel by a team led by A.A Andreyev, with MiG directed to build a variable-geometry prototype, the "23-11" in 1965.Based on the RP-22SM Sapfir-21 radar with an ASP-PFD-21 lead computing gunsight, it could carry only four R-3/K-13 (AA-2 "Atoll") air-to-air missiles (typically two SARH R-3Rs and two IR R-3Ss) in addition to a Gryazev-Shipunov GSh-23L autocannon.[14][15] The MiG-23's ejection seat, the KM-1, was built with extreme altitude and speed in mind: leg stirrups, shoulder harness, pelvic D-ring, and a 3-parachute system.Engaging the ejection seat could take a long time, as the pilots had to place their feet in the stirrups, let go of the control column, grab the two trigger handles, squeeze and lift them.The first parachute, the size of a large handkerchief, was deployed out of a telescoping rod which would pop out of the top back of the seat as it started to clear the windscreen windbreak area.This required that the fighter be flown very close to the target's altitude and well ahead of it to be picked up, necessitating good ground-controlled interception (GCI) instructions.In the summer of 1977, after a political realignment by its government, Egypt provided a number of MiG-23MSs and MiG-23BNs to the United States; these were evaluated under a pair of exploitation programs codenamed HAVE PAD and HAVE BOXER respectively.These and other MiGs, including additional MiG-23s acquired from other sources, were used as part of a secret training program known as project Constant Peg to familiarize American pilots with Soviet aircraft.[27] Initially, American intelligence on the MiG-23 assumed that the fighter could turn well and had reasonable acceleration capability, but testing during HAVE PAD proved this assumption to be incorrect.While its turning capability was comparable to an original F-4E Phantom, newer American fighters like the F-15 Eagle or F-4E upgraded with slats could easily out-turn the MiG-23 in a dogfight.In the training environment the Blue Air pilots would do their intercepts at 350 to 400 knots, so when they all of a sudden get this Flogger coming at Mach 1.5, it really changes the geometry of things.The second was to simulate the MiG-25 Foxbat, a high, fast flyer which would be going after high-value targets such as aerial refueling or airborne early warning and control aircraft like the E-3 Sentry.[30] According to the MiG-23ML technical manual, the MiG-23ML has a instantaneous turn rate of 16.7 deg/s and a sustained of 14.1 deg/s at 1 km (3,300 ft) of altitude and at a speed of 490 kn (900 km/h); and at maximum 7g load factor.Stability issues and limited maneuverability resulted in numerous flight restrictions placed on the fighter as efforts to rectify these concerns began in the mid-1970s.However, throughout the 1970s and early 1980s Soviet pilots continued to train and operate the MiG-23 in the same inflexible manner as the MiG-21: a high-speed point defense interceptor closely guided by GCI.This developed into a disaster when the MiG-23s failed to provide adequate air cover and the strike force accidentally crossed into Iran, losing several helicopters to Iranian F-4 Phantoms.[47] Sorties with dumb bombs and cluster munitions were flown against a wide range of targets, while more sophisticated weaponry was not often employed because of the difficult terrain and threat of MANPADs and AA.The second instance of MiG-23s serving with the Soviet Navy occurred from 1990 to 1994, when nine MiG-23UB trainers were attached to the 88th Separate Fighter Bomber Regiment of the Northern Fleet's aviation component to train pilots for their MiG-27s.The first interceptor variant to be exported, the MiG-23MS, was equipped with the same weapons system as the older MiG-21S, and its radar was particularly vulnerable to electronic countermeasures (ECM), at which the Israelis were especially proficient.[52] On 13 April 1974, after almost 100 days of artillery exchanges and skirmishes along the Golan Heights, Syrian helicopters delivered commandos to attack the Israeli observation post at Jebel Sheikh.Thanks to the decreased presence of IRIAF interceptors and to the much-improved protection offered by escort, SEAD and electronic countermeasures aircraft, losses were much lower than during the first months of the war.South African ground forces shot down a MiG-23, which was prosecuting a raid on the Calueque Dam, by using the Ystervark (porcupine) 20 mm AA gun.[89][90] One Libyan MiG-23MS was shot down by an Egyptian MiG-21 fighter during and immediately after the Libyan–Egyptian War in 1977 while supporting a strike on the airfield at Mersa Matruh, forcing the remaining MiG to abort the mission.The Libyan pilots made the mistake of trying to outmaneuver the more nimble Egyptian MiG-21s, and one MiG-23MS was shot down by Maj. Sal Mohammad with an AIM-9P3 Sidewinder missile, while the other used its superior speed to escape.[103] On 15 March 2011, a rebel website reported that opposition forces started using a captured MiG-23 and a helicopter to sink 2 loyalist ships and bomb some tank positions.[106] On 26 March 2011, five MiG-23s together with two Mi-35 helicopters were destroyed by the French Air Force while parked at Misrata airport, early reports misidentified the fixed wing aircraft as G-2 Galebs.[109] On 23 March 2015, a New General National Congress operated MiG-23UB was shot down while bombing Al Watiya airbase, controlled by the Libyan House of Representative probably with an Igla-S MANPADS.[119] The jet was hit over the Yarmouk frontline in southern Tripoli and crashed in Al Zawiya city and the pilot, Amer Jagem was detained after ejecting.According to a 1990 Human Rights Watch report, the attacks, often using napalm or phosphorus and cluster munitions, were not only aimed at the rebels, but against civilian populations (in both Eritrea and Ethiopia) and humanitarian convoys in a deliberate fashion.They quickly entered service fighting against the South Sudan People's Defence Forces (SPLA) in 1988 during the Second Sudanese Civil War.
