Auxiliary Fuel Tank

The NAVAIR PMA-276 H-1 Light/Attack Helicopter is seeking information for potential sources regarding in-cabin, auxiliary, fueling and storage capability for the UH-1Y aircraft. During deployment, UH-1Y aircrews require an increase in fuel capability to facilitate extended aircraft range and loitering time. The intention is to procure the material on a competitive basis if two or more capable responsible sources exist in the marketplace.

3.0 SPECIAL REQUIREMENTS AND REQUIRED CAPABILITIES
