Lrip OTA 125B

Naval Air Systems Command awarded an Other Transaction IDV to Undersea Sensor Systems, Inc., Ultra Maritime Division (operating as Ultra Sonobuoy Systems) on February 11, 2026, with a ceiling of $99.996 billion. This multiple-award OTA sits outside the FAR and supports low-rate initial production of advanced undersea sensor systems for anti-submarine warfare and maritime surveillance.

Undersea Sensor Systems manufactures sonobuoy variants including AN/SSQ-53H, AN/SSQ-62G, SSQ-101B, and ER-DIFAR models, along with hydrophone assemblies, radio receivers, preamplifiers, and signal processing components. The company operates manufacturing facilities in Columbia City, Indiana and Victor, New York. LRIP 125B is one of three multiple-award OTA IDVs supporting production transition; the Q53H LRIP vehicle (awarded August 7, 2024, $99.999 billion ceiling) and SSQ-125A prototype development vehicle (awarded March 27, 2024, $7.698 million ceiling) form the companion portfolio. These OTAs complement the $1.653 billion MADOC IDIQ, which anchors the vendor's largest concentration of future work through 29 task orders.

Recent ordering activity under related vehicles reflects sustained production demand: a $236.5 million firm-fixed-price delivery order for AN/SSQ-53H sonobuoy production (completion March 2028), a $153.4 million order for AN/SSQ-53H sonobuoys with Pho-Tronics H & T Global Circuits subcontracting on printed wiring board assemblies (completion June 2, 2027), and a $136.9 million order for active-passive combo sonobuoys with Mack Technologies supplying GPS receiver modules (completion September 17, 2027). A $98 million OTA for AN/SSQ-62G low-rate initial production (awarded June 14, 2024, completion May 28, 2026) demonstrates the vendor's prototype-to-production transition role.
