LONDON, — May 21, 2026 : GE Aerospace has been awarded a three-year contract by Boeing Defence UK to provide engine support services for the British Army’s fleet of AH-64E Apache Guardian attack helicopters.
The agreement covers maintenance and support for the T700-GE-T701D turboshaft engines powering the AH-64E fleet and establishes a localized support network within the United Kingdom intended to improve aircraft availability and operational readiness while reducing dependence on overseas repair channels.
The contract is structured under a Performance Based Logistics (PBL) model, under which compensation is tied directly to operational performance metrics such as fleet readiness and aircraft availability rather than the number of labor hours performed or spare parts supplied. The arrangement is designed to align industrial support with the British Army’s operational requirements by incentivizing reduced downtime and sustained mission capability.
As part of the agreement, GE Aerospace will permanently station a field service representative at Wattisham Flying Station, the British Army’s primary Apache operating base in Suffolk. The on-site support presence is intended to provide immediate technical assistance to military maintenance crews and flight operations personnel.
Major repair and overhaul work for the engines will be carried out at StandardAero’s facility in Gosport on England’s south coast. The site serves as a major rotary-wing maintenance, repair, and overhaul hub supporting several UK military aviation programs.
Paul Ferraro, Vice President and General Manager for Defense Engines and Services at GE Aerospace, said the contract strengthens regional support and services for the UK Apache fleet while helping ensure readiness and availability.
The T700-GE-T701D is the latest production variant of the T700 engine family, which has remained in continuous production since the late 1970s. The engine produces approximately 1,800 shaft horsepower and incorporates full-authority digital engine control (FADEC), improving fuel efficiency, engine management, and pilot workload compared with earlier variants.
According to publicly available program data, the T700 engine family has accumulated more than 100 million flight hours worldwide, with over 25,000 engines delivered to approximately 130 operators across 50 countries. In addition to the Apache, the engine family powers platforms including the UH-60 Black Hawk and the SH-60 Seahawk.
The British Army is currently transitioning from the earlier AH-64D Longbow Apache to the AH-64E Guardian under a government-to-government agreement signed with the United States in 2020. The modernization effort follows two decades of operational service by the AH-64D fleet, including combat deployments in Afghanistan. The UK plans to field a fleet of 50 AH-64E helicopters.
The AH-64E variant incorporates upgraded avionics, improved networking capability, enhanced sensors, and greater interoperability with allied forces. The aircraft is also capable of coordinating operations with unmanned aerial systems.
The UK Apache modernization effort aligns with broader allied procurement trends. Australia is also acquiring the AH-64E under Project LAND 4503, reflecting continued allied investment in the Boeing platform and its support infrastructure.
Because the T700 engine family supports a significant portion of NATO and allied helicopter operations across missions including close air support, air assault, medical evacuation, maritime patrol, and search and rescue, maintaining regional maintenance and supply-chain capability remains an important operational requirement for allied forces.
The three-year contract provides the British Army with a dedicated domestic repair and support framework intended to sustain Apache fleet readiness and ensure consistent engine maintenance aligned with operational requirements.
