The ITEP plans to re-engine over 1,300 Sikorsky UH-60 Black Hawk and more than 600 Boeing AH-64 Apache, and to power the Future Attack Reconnaissance Aircraft, beginning after 2025.

[1] The T900 was developed by the Advanced Turbine Engine Company (ATEC), a joint venture between Honeywell Aerospace and Pratt & Whitney.

[4] In August 2016, the Army awarded ATEC a $154 million, two-year preliminary design review contract to further support development of the replacement engine.

[8] On 1 February 2019, the US Army selected the General Electric T901 as the winner of the ITEP program, awarding the Engineering and Manufacturing Development (EMD) contract for $517 million.

[13] The engine's increased power is designed to allow Black Hawk and Apache helicopters to fly higher and longer with more soldiers or payload in hotter climates.
