### Description

<p>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.</p>

<p></p>

<p>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&rsquo;s INS requirements by satisfying new construction ship and backfit deliveries, along with Foreign Military Sales (FMS) deliveries from FY 2031 through FY 2036.</p>
