1993) in its McDonnell Douglas F/A-18 Hornet squadrons. The Russian Air Force counterpart of AMRAAM is the somewhat similar R-77 (NATO codename AA-12 Adder), sometimes referred to in the West as the "AMRAAMski". Likewise, France began its own air-to-air missile development with the MICA concept that used a common airframe for separate radar-guided and infrared-guided versions. Operational history United States The AMRAAM was used for the first time on December 27, 1992, when a USAF General Dynamics F-16D Fighting Falcon shot down an Iraqi MiG-25 that violated the southern no-fly-zone. This missile had been returned from the flight line as defective a day earlier. The AMRAAM gained a second victory in January 1993 when an Iraqi MiG-23 was shot down by a USAF F-16C. On 28 February 1994, a Republika Srpska Air Force J-21 Jastreb aircraft was shot down by a USAF F-16C that was patrolling the UN-imposed no-fly zone over Bosnia. In that engagement, at least three other Serbian aircraft were shot down by USAF F-16Cs using AIM-9 missiles (Banja Luka incident). At that point, three launches in combat had resulted in three kills, resulting in the AMRAAM's being informally named "slammer" in the second half of the 1990s. In 1994, two USAF F-15 fighters patrolling Iraq's Northern No-Fly Zone mistook a pair of US Army Black Hawk helicopters for Iraqi helicopters, and shot them down. One was downed with an AIM-120, and one with an AIM-9 Sidewinder. In 1998 and 1999 AMRAAMs were again fired by USAF F-15 fighters at Iraqi aircraft violating the No-Fly-Zone, but this time they failed to hit their targets. During spring 1999, AMRAAMs saw their main combat action during Operation Allied Force, the Kosovo bombing campaign. Six Serbian MiG-29s were shot down by NATO (four USAF F-15Cs, one USAF F-16C, and one Dutch F-16A MLU), all of them using AIM-120 missiles (the supposed kill by the F-16C may have actually been friendly fire, a man-portable SA-7 fired by Serbian infantry). On 18 June 2017, a US Boeing F/A-18E Super Hornet engaged and shot down a Sukhoi Su-22 of the Syrian Air Force over northern Syria, using an AIM-120. An AIM-9X Sidewinder had failed to bring down the Syrian jet. Some sources have claimed the AIM-9X was decoyed by flares, although the F/A-18E pilot, Lieutenant Commander Michael Tremel stated it was unclear why the AIM-9X failed, mentioning no use of flares by the Su-22,
