Description

The Naval Sea Systems Command (NAVSEA) intends to utilize other than full and open competition to award a contract modification to the existing awarded contract N00024-22-C-5231 to extend the period of performance through fiscal year (FY) 2028. The base contract was awarded to Leidos, Inc. of Reston, Virginia (1750 Presidents Street, Reston, Virginia 20190-5661) for installation, spares procurement, integrated logistic support, fleet maintenance support, and lifecycle sustainment of the U.S. Navy’s AN/SQQ-89 Surface Ship Undersea Warfare Combat Systems in support of Portfolio Acquisition Executive Mission Systems PMW 650. The proposed contract action is for supplies and services for which the Government intends to solicit and negotiate with only one source under authority FAR 6.103-1. No other company could make these supplies on a timeline that would serve the Government’s needs. This notice is not a request for competitive proposals. Interested persons may identify their interest and capability to respond to the requirements. However, all expressions of interest received within fifteen (15) days after the date of publication of this synopsis, will be considered by the Government. Any submission will not be reimbursed by the Government and the entire cost of any submission will be at the sole expense of the source submitting the information. A determination by the Government not to compete this proposed contract, upon receipt of responses, is the sole discretion of the Government. Note:
