The Propulsion Integration Division, AFLCMC/LPZ, intends to award three sole-source contracts for the Engine Component Improvement Program to RTX Corporation (Pratt & Whitney), General Electric Aerospace, and Rolls-Royce Corporation. Market research determined this is a sole-source requirement because these firms are the original equipment manufacturers and only they possess the necessary knowledge, experience, and technical data. This notice is not a request for proposals and no solicitation is available, but capable firms may respond in writing with clear and convincing evidence of their ability to provide timely and effective services, which will be considered solely to determine whether to compete the action. The anticipated award date is 29 October 2027. Subcontracting opportunities are available through contacts at each OEM, and the NAICS code is 541715 with a size standard of 1,500 employees.
