This is a procurement for 264 Vane Segment Assemblies, which are critical safety items requiring first articles and qualification, with delivery requested on or before March 15, 2027. The government intends to solicit and negotiate with only one or a limited number of sources, specifically identifying Rolls-Royce Corporation and Pacific Sky Supply as approved sources. A previous contract for 12 units was awarded at a unit price of $5,882.71. While this is a notice of intent and not a formal request for competition, proposals received within 45 days of the synopsis publication will be considered. The solicitation will be available electronically, and an ombudsman is appointed to address concerns during the proposal phase.
