This is a notice of the government's intent to award a sole-source contract to Rolls-Royce Corporation for the manufacture of a specific Hydraulic Actuator for the RQ-4 Global Hawk program. The justification is that Rolls-Royce is the original equipment manufacturer and the government lacks the technical data needed for another company to produce the compatible part. Other interested parties may identify their interest and capability to respond to the requirement. This is a sources sought notice for market research and is not a formal solicitation.
