The Naval Air Systems Command intends to issue a sole-source contract modification to L3Harris Technologies in Salt Lake City, UT, to continue development of the NGJ-LB system to full capability. The work includes delivering test articles, implementing cybersecurity requirements, and providing product support, logistics, and testing. The justification for a sole-source award is that L3Harris is stated to be the only source with the necessary technical data, skills, and knowledge to perform the work without substantial cost duplication. This synopsis is for informational purposes only and is not a request for competitive proposals, though the government will consider capability statements from interested parties. The performance location is Salt Lake City, UT.
