The United States Defense Security Cooperation Agency (DSCA) has advised to Congress that there may be a potential foreign military sale (FMS) of AH-64E Apache Guardian attack helicopters, along with all of the associated equipment, to the United Kingdom. Under this sale, which is estimated to have a value of $3 billion, the United Kingdom’s government has requested the remanufacture of 50 WAH-64 Mk1 attack helicopters into AH-64E Apaches equipped with 110 T-700-GE-701D engines.
