On 21 March 2011, an F-15E from the 492d FS crashed near Bengazi, Libya. Both crew members parachuted into territory held by resistance elements of the Libyan population and were eventually rescued by US Marines. Equipment problems caused a weight imbalance and contributed to the crash when leaving the target area. USAF F-15Es have participated in Operation Inherent Resolve against Islamic State (IS) militants in Iraq and Syria. On the morning of 23 September 2014, numerous American and Arab aircraft conducted air strikes in Syria against IS fighters, training compounds, headquarters and command and control facilities, storage facilities, a finance center, supply trucks, and armed vehicles. The Pentagon releasing videos of targets hit by ordnance deployed by F-15Es, taken by their own AN/AAQ-33 Sniper targeting pods. Between August 2014 and January 2015, F-15Es flew 37 percent of all USAF sorties. USAF F-15Es based at RAF Lakenheath in the United Kingdom performed several long range surgical strikes against IS camps and prominent figures in Libya. On 13 November 2015, a pair of F-15Es killed Abu Nabil al-Anbari, the leader of the Islamic State of Iraq and the Levant in Libya, in a strike near Darnah, Eastern Libya. On 20 February 2016, USAF F-15Es hit an IS training camp near Sabratha where foreign fighters were based, reportedly killing Noureddine Chouchane, a 36-year-old Tunisian jihadist linked to the 2015 Sousse attacks. Sources said that 49 people were killed and 6 wounded; two Serbians kidnapped by IS in 2015 were also reportedly killed. On 8 June 2017, an F-15E shot down a pro-Syrian Regime UAV near Al Tanf, Syria; according to OIR officials, it was downed after deploying "one of several weapons it was carrying near a position occupied by Coalition personnel... [It was] similar in size to a U.S. MQ-1 Predator". The drone may have been a Shahed 129; on 20 June 2017, a second Shahed-129 was downed by an F-15E near the 50 mile exclusion zone around Al-Tanf. The F-15I is operated by the Israeli Defense Force/Air Force No 69 Squadron, succeeding the F-4 Phantom II. It is used akin to a strategic bomber due to its long range, high munition capacity and advanced systems. After the Gulf War in 1991, in which Israeli towns were attacked by SCUD missiles based in Iraq, the Israeli government decided a long range strike aircraft was needed, issuing a Request for Information (RFI).
