Description

Portfolio Acquisition Executive Mission Systems (PAE MS) PMW/A 520 intends to utilize other than full and open competition to award an AN/WSN-12 Full Rate Production (FRP) contract to Northrop Grumman Systems Corporation (NGSC). The AN/WSN-12 FRP contract will be a follow-on contract to the existing AN/WSN-7/7A Ring Laser Gyro Navigators (RLGN) and AN/WSN-7B Ring Laser Gyrocompasses (RLG) production contract (N00024-20-D-5230) and AN/WSN-12 Inertial Sensor Module (ISM) contract (N00024-23-C-5234). The N00024-20-D-5230 contract was awarded to NGSC for AN/WSN-7 Inertial Navigation Systems (INS) production in September 2020. The N00024-23-C-5234 contract was awarded to NGSC for AN/WSN-12 ISM component FRP in December 2022. The AN/WSN-12 Inertial Navigation System (INS) has two main components, the Inertial Sensor Module (ISM) and the Navigation Processor Module (NPM). The planned AN/WSN-12 FRP contract will provide the necessary production, engineering support, training, First Article Testing (FAT), and spares for the AN/WSN-12 ISM and NPM surface configuration and includes the procurement of AN/WSN-12 submarine ISMs. This contract will address the United States Navy’s INS requirements by satisfying new construction ship and backfit deliveries, along with Foreign Military Sales (FMS) deliveries from FY 2031 through FY 2036. Note: The proposed contract action is for supplies for which the Government intends to solicit and negotiate with only one source under the authority of FAR 6.302-1.
