The Department of Defense, through the Naval Surface Warfare Center (NSWC) Crane Division, is seeking to modify an existing contract for Contractor Sustainment Support (CSS) Services related to the Target Sight Systems (TSS) provided by Lockheed Martin Corporation. The modification aims to extend the period of performance for engineering, logistics support, and Foreign Military Sales (FMS) associated with the AN/AAQ-30 series of TSS until September 30, 2025, with an anticipated value of approximately $10 million. This procurement is critical as Lockheed Martin is the sole designer and manufacturer of the TSS, possessing the unique technical expertise and resources necessary to fulfill the government's requirements. Interested parties can direct inquiries to Valerie Smith at valerie.c.smith25.civ@us.navy.mil, with the proposal anticipated to be awarded by September 30, 2024.
