The Department of Defense, through the Naval Air Systems Command, intends to issue a delivery order to Sikorsky, A Lockheed Martin Company, for the provision of Illustrated Parts Breakdown (IPB) technical manuals for the CH-53K airframe and structural components. This procurement is being conducted on a sole source basis due to Sikorsky's unique position as the sole designer, developer, and manufacturer of the H-53 airframe, which necessitates their specialized knowledge and experience to meet the Government's requirements effectively. The technical manuals are critical for the maintenance and operational readiness of the CH-53K aircraft, ensuring that all components are accurately documented for use by military personnel. Interested parties may express their interest and capabilities, but the Government retains discretion over the competitive process. For inquiries, contact William A. Hess at william.a.hess@navy.mil.
