The AH Mk.1 Apache is a British license-produced version of the American AH-64D, assembled by AgustaWestland from Boeing-supplied kits and featuring more powerful Rolls-Royce Turbomeca engines. Entering service in 2005, the Apache replaced the Lynx in British tactical operations, seeing combat in operations in Afghanistan from 2007 and Libya from 2011. Unlike their American counterparts, some AH Mk.1s were partially navalised, including a folding-blade mechanism, allowing them to operate from ships in addition to land-based roles. The existing AH Mk.1s in service are planned to be retired and refitted to the AH-64E standard from 2024.

Introduced in Update 1.97 "Viking Fury", the AH Mk.1 is the pinnacle of the British helicopter tree, featuring more powerful armaments, advanced avionics, and better survivability over the preceding Lynx, while maintaining similar levels of speed and manoeuvrability. Even compared to its Apache brethren, the AH Mk.1 is distinguished by its Rolls-Royce Turbomeca engines, making it the fastest AH-64 variant in the game. Additionally, the domestic Starstreaks, while manually guided and lacking in explosive filler or proximity fuse, are certainly not a downgrade compared to the AIM-92 Stingers, as they are not decoyed by countermeasures, making them highly effective against other helicopters, and are able to run a dual purpose in the anti-tank role against lightly armoured targets with their high speed, low visibility, and reasonable armour penetration.
