also suffer from fewer malfunctions and other problems (high, 70–75% non-error index). It is also the only aircraft in Polish inventory equipped for electronic intelligence, warfare, and support of ground systems. The Polish Air Force had retained a large stockpile of air-to-ground weapons for use with the Su-22. By some estimates, the cost of destroying these resources would be higher than the projected cost of continuing Su-22 operations. It was decided that starting from 2015, only 12 Su-22M4s and 4-6 Su-22UM3Ks out of 32 remaining would undergo a refit, increasing their lifespan for another ten years. For economical reasons the aircraft are not modernized, apart from fitting an additional RS-6113-2 C2M radio with a blade antenna on the top, but they receive a new grey multishade camouflage, similar to other Polish aircraft. Several Polish Su-20s and Su-22s have since been donated to various museums, including the Polish Army Museum in Warsaw, the Armament Museum in Poznań, the Museum of Polish Arms in Kołobrzeg and the Polish Aviation Museum in Kraków. Other were placed on monuments or donated to schools as technical aids. Following the acquisition of 48 KAI T-50 Golden Eagle aircraft from South Korea in 2022, Su-22 will be successively phased out and retired. Syria The Syrian Air Force (SyAAF) used Su-20/-22s to attack Israeli forces in the Yom Kippur War and 1982 Lebanon War. Several Su-20/-22s were shot down by the Israeli Air Force. From mid-2012, in the Syrian Civil War, Syrian Air Force Su-22s were involved in combat operations against Syrian insurgents. Videos showed Su-22s using unguided munitions like other SyAAF fixed wing aircraft; mostly general-purpose bombs, cluster bombs and incendiary bombs and unguided rockets. Attack tactics were low to medium-altitude flat bombing runs with pull up after rocketing or bombing, with decoy flares deployed for self-defense. As of the end of 2015, the SyAAF Su-22s suffered a limited number of losses compared to the SyAAF MiG-21 and MiG-23 during the same period. The first confirmed loss of an SyAAF Su-22 was recorded on 14 February 2013, when rebel forces shot it down using a MANPADS. On 18 June 2017, a US F/A-18E Super Hornet engaged and shot down an SyAAF Su-22 for dropping munitions on US-backed forces. According to the wingman of the Super Hornet that made the kill, the Syrian pilot was able to eject and was later returned to the Syrian government. On 24
