The Naval Air Systems Command intends to issue a sole-source delivery order to the Bell Boeing Joint Program Office for V-22 avionics software support activities. The work includes engineering, management, and technical efforts to sustain existing software and develop future releases. The statutory authority for other than full and open competition is cited, as the Bell Boeing JPO is deemed the only responsible source with the requisite knowledge and data. Subcontracting opportunities may exist, and contact information for both companies is provided.
