The Performance Assessment (PA) Department of the Naval Surface Warfare Center Corona Division intends to award a sole-source, firm fixed price contract to General Dynamics Satellite Communications (GDSATCOM) for a 7.3m Ku-band satellite antenna to provide high data rate transfer between ships and the Ground Station in Corona CA. Purchase of a 7.3m Cassegrain Ku-band Antenna System and turnkey installation service will provide a backup antenna for the first three 7.3m antennas which PA has already purchased from GDSATCOM. The 7.3m Ku-band antenna is a key component of the Ground station, which provides secure voice communications and high speed data transferring. This antenna will be used to communicate with navy's ships during Ballistic Missile Defense (BMD) and Combat Ship System Qualification Trial (CSSQT) events. The cost associated with a new model number would not be recouped as a result of a competitive procurement and are not in the government's best interest. No additional units are anticipated, as this buy will complete the inventory objective. The Government intends to award a sole-source, firm fixed price contract to General Dynamics SATCOM Technologies, 2600 N. Longview Street, Kilgore, TX 75662. This procurement is commercial item IAW FAR Part 13. The associated NAICS Classification is 334220 and the size standard is 750 employees. No solicitation will be issued but responsible sources may submit inquiries to Walter Knapp at walter.knapp@navy.mil or interested parties may inquire by phone at (951) 393-4047. THE GOVERNMENT INTENDS TO SOLICIT AND NEGOTIATE WITH ONLY ONE SOURCE IN ACCORDANCE WITH THE STATUTORY AUTHORITY 10 U.S.C. 2304(C)(1) AS IMPLEMENTED BY FAR 6.302-1 FOR THIS PROCURMENT ACTION. INTERESTED PARTIES MAY IDENTIFY THEIR INTEREST AND CAPABILITY TO RESPOND TO THE REQUIREMENT, OR SUBMIT CAPABILITY STATEMENTS. THIS NOTICE OF INTEREST IS NOT A REQUEST FOR COMPETITIVE QUOTES OR PROPOSALS.
