About this opportunity
The Naval Air Warfare Center Weapons Division has awarded a sole-source contract to ThinKom Solutions for procurement of cylindrical antennas on August 4, 2026, with an estimated value of $809,000.
The award is justified under 10 U.S.C. 3204(a)(1), only one responsible source and no other supplies or services will satisfy agency requirements. ThinKom is the original designer, developer, and manufacturer of the proprietary cylindrical elevation beam scanning antenna subsystem utilizing Continuous Transverse Stub technology, having completed initial design and prototype development in 2005 under contract N6893606C0012. The procurement covers 11 cylindrical antenna subassemblies for the PATRIOT Radar Program supporting the United States Navy Virginia Class Fleet of submarines. A sources sought notice was posted to SAM.gov on February 6, 2026, and a presolicitation synopsis on February 18, 2026; no viable alternative sources submitted complete capability submissions. The contracting officer determined that redesigning the antenna to enable competition would require a minimum two-year effort by five engineers at an estimated cost of $1.6 million and would necessitate redesign of the entire PATRIOT Radar Program. The contract is a Firm Fixed Price SF 1449 solicitation/RFQ pursuant to FAR 12.204(a)(1), with a delivery lead time of 34 weeks after contract receipt. Place of performance is China Lake, California. ThinKom's prior awards for this antenna include contracts dated September 25, 2024 and September 27, 2023. The contracting officer has no current plans to compete future contracts unless another potential source emerges.
