 In August 2015, the UK requested through a Foreign Military Sale, the upgrade of 50 of its Apaches to AH-64E standard. In July 2016, the UK placed an order for 50 AH-64Es through the US Foreign Military Sales (FMS) programme instead of upgrading their AgustaWestland-built AH-64s. Leonardo Helicopters (formerly AgustaWestland) will continue to lead the support the existing Apache AH1s until they are retired from service in 2023 – 24.
