In accordance with FAR 6.302-1(a)(2), the Government has deemed the requirements listed above to be available only through the original source and award to any other source would result in substantial duplication of cost to the Government that is not expected to be recovered through competition. BAE Systems is the Original Equipment Manufacturer (OEM) of both the hardware and software of the LPIA, to include the RT-1805/APN-02, RT-1805/APN-04, RT-1805/APN-05, and software for each system. As the sole designer, developer and OEM, BAE Systems is therefore the only company that has the ability, resources, technology and documentation necessary to modify, develop, produce, maintain and support these systems. Therefore, BAE Systems is the only responsible source and no other supplies or services will satisfy agency requirements. THIS NOTICE OF INTENT IS NOT A REQUEST FOR PROPOSALS. The Government does not intend to fund the development or qualification of other sources for fulfilling this requirement. However, interested parties may identify their interest and capability by responding to this requirement.
