The F-15I is operated by the Israeli Air Force where it is known as the Ra’am (רעם – “Thunder”). It is a dual-seat ground attack aircraft powered by two Pratt & Whitney F100-PW-229 engines, and is based on the F-15E.
The F-15I features different avionic systems to USAF F-15E to meet Israeli requirements. Initially, Sharpshooter targeting pods designed for IAF F-16s were fitted for night-time strikes, but were less capable than the LANTIRN pods used on USAF F-15Es; Israel later bought 30 LANTIRN pods. The F-15Is initially lacked Radar Warning Receivers; Israel installed its own Elisra SPS-2110 electronic warfare equipment as well as a new central computer and embedded GPS/INS system. All sensors can be slaved to the Display and Sight Helmet (DASH) helmet-mounted sight, providing both crew members a means of targeting which the F-15E lacks. The F-15I uses the APG-70I radar; its terrain mapping capability can locate targets difficult to spot while under adverse weather conditions and can detect large airliner-sized targets at 150 nautical miles (170 mi; 280 km), and fighter-sized targets at 56 nmi (64 mi; 104 km); it has a reduced resolution one-third below the APG-70. In January 2016, Israel approved F-15I upgrades such as structural changes, an AESA radar, updated avionics, and new weapons.
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). In response, Lockheed Martin offered a version of the F-16 Fighting Falcon, while McDonnell Douglas offered both the F/A-18 Hornet and the F-15E. On 27 January 1994, the Israeli government announced their intention to buy 21 modified F-15Es, designated F-15I. On 12 May 1994, the US Government authorized the purchase of up to 25 F-15Is by Israel. In November 1995, Israel ordered four extra F-15Is; 25 were built from 1996 to 1998. Some of the air-to-air missiles aircraft can carry: the AIM-9L, Rafael Python 4 and the Rafael Python 5 infrared-homing missiles; and the AIM-7 Sparrow and the AIM-120 AMRAAM radar-guided missiles. In 1999, Israel announced its intention to procure more fighters and that a possible contender was the F-15I. However, the contract went to the F-16I.
