with air traffic control (ATC) warnings; an IAF AH-64A fired on the Cessna, resulting in its disintegration. The second air-to-air kill occurred on 10 February 2018, after an Iranian UAV entered Israeli airspace from Syria, an AH-64 destroyed it with a missile. United Kingdom The UK currently operates a modified version of the AH-64D Block I Apache Longbow; initially called the Westland WAH-64 Apache, it is designated the Apache AH1 by the British Army. Westland built 67 WAH-64 Apaches under license from Boeing, following a competition between the Eurocopter Tiger and the Apache for the British Army's new Attack Helicopter in 1995. Important deviations made by AgustaWestland from the U.S. Apache variants include changing to more powerful Rolls-Royce engines, and the addition of a folding blade assembly for use on naval ships. On 11 July 2016, the Ministry of Defence confirmed a U.S. Foreign Military Sale (FMS) worth $2.3 billion for 50 AH-64Es to be built in Mesa, Arizona. Leonardo Helicopters in the UK is to maintain the current fleet of Apaches until 2023–2024, with a long-term plan for Leonardo and other UK companies to "do most of the work" on the new fleet. The deal includes an initial support contract for maintenance, spare parts, and training simulators; components from the older WAH-64s "will be reused and incorporated into the new helicopters where possible." The type is due to enter service with the British Army in 2022. Approval for the re-manufacture of fifty of the UK's WAH-64 Mk 1 fleet to AH-64E Apache Guardian standard had been given by the Defense Security Cooperation Agency in August 2015. They will utilize the General Electric T700 engine rather than the Turbomeca RTM322 of the WAH-64; the first off-the-shelf purchase of a GE engine by the Ministry of Defence. The first two AH-64Es were delivered to the British Army on 26 November 2020. Netherlands The Dutch government initially showed an interest in acquiring Apache helicopters in the late 1980s, when it stated that it may purchase as many as 52. A competition held in 1994 against the Eurocopter Tiger and the Bell AH-1 SuperCobra led to the Royal Netherlands Air Force ordering 30 AH-64D Apaches in 1995. Deliveries began in 1998 and ended in 2002. The RNLAF Apaches are equipped with the Apache Modular Aircraft Survivability Equipment (AMASE) self-protection system to counter infrared (IR) missile threats. The RNLAF Apaches' first deployment was in
