to the passage below and then answer the question afterwards in the same language as the passage: Passage: The Israeli Air Force was the largest foreign operator of the Phantom, flying both newly built and ex-USAF aircraft, as well as several one-off special reconnaissance variants. The first F-4Es, nicknamed "Kurnass" (Sledgehammer), and RF-4Es, nicknamed "Orev" (Raven), were delivered in 1969 under the "Peace Echo I" program. Additional Phantoms arrived during the 1970s under "Peace Echo II" through Israeli "Peace Echo V" and "Nickel Grass" programs. Phantoms saw extensive combat during Arab-Israeli conflicts, first seeing action during the War of Attrition. In the 1980s, Israel began the "Kassurn 2000" modernization program which significantly updated avionics. The last Israeli F-4s were retired in 2004.
