Setra Systems, Inc.

Setra Systems, Inc., doing business as Gems Sensors, manufactures precision electronic monitoring components—liquid transmitters, switches, flow meters, cable assemblies, and circuit card assemblies—for defense and maritime customers as a prime contractor on full-and-open Department of Defense contracts and as a subcontractor to major defense primes. The company is a for-profit limited liability corporation headquartered in Plainville, Connecticut, and a subsidiary of Advanced Sterilization Products Italia S.R.L. Gems Sensors competes exclusively on unrestricted awards with no set-aside participation across its prime footprint.

Gems Sensors' customer concentration is heavily weighted to Defense Logistics Agency (DLA) components. The top five funding agencies account for 91% of recent awards by count and 95% by combined potential value. DLA Aviation leads by a wide margin—1,307 awards totaling $43.6 million combined potential value—followed by DLA Land and Maritime (992 awards, $18.3 million). The Department of the Navy's Naval Sea Systems Command and Naval Supply Systems Command together represent 726 awards and $8.1 million, while the Department of Homeland Security U.S. Coast Guard contributes 92 awards and $1.1 million. The dollar and award-count rankings align closely, indicating Gems Sensors has achieved consistent positioning across its customer base without large-dollar outliers skewing concentration metrics.

Recent capability work includes a $223,900 firm fixed-price purchase order from Naval Sea Systems Command awarded March 26, 2026, for precision electronic monitoring components including liquid transmitters, switches, flow meters, and cable assemblies for military platforms with completion by November 2026; a $201,250 sole-source purchase order from Naval Sea Systems Command for monitoring panels with 4-digit receiver capability; a $267,306 firm fixed-price delivery order from DLA Aviation for receiver and indicator components; and a $129,100 sole-source purchase order from Naval Air Warfare Center for oil level indicators supporting the Electromagnetic Aircraft Launch System on the CVN 80 aircraft carrier. The company holds multiple single-award indefinite delivery contracts with DLA Aviation and DLA Land and Maritime collectively valued up to $1.25 million, supporting recurring orders through 2025 and 2028. A new DLA Aviation IDC awarded October 3, 2025, carries a ceiling of $287,233.93 through October 2, 2030, enabling streamlined procurement of electronic monitoring components for military aviation platforms.

Activity has contracted significantly in recent years—222 awards in 2022 declining to 31 in 2024 and 31 in 2025—signaling either market contraction, customer consolidation, or portfolio shift. Only two awards face completion inside the next twenty-four months, totaling $239 thousand combined potential value, resulting in minimal recompete pressure in that window. The vendor's product category concentration reflects its core capability: Liquid and Gas Flow, Liquid Level, and Mechanical Motion Measuring Instruments account for 1,896 awards (the largest single PSC grouping); Switches represent 610 awards; and Other Measuring and Controlling Device Manufacturing accounts for 1,200 awards across the NAICS portfolio.

Gems Sensors serves as a subcontractor to major defense shipbuilding and systems integration primes. Named subcontracting relationships include Huntington Ingalls Incorporated (DDG 51 destroyer and LPD 30 amphibious transport dock construction; CVN 80 aircraft carrier engineering and steel work, providing tank level indicators, receiver indicators, and circuit card assemblies), General Dynamics Information Technology, Inc. (C5ISR systems support task orders under the NAWCAD WOLF contract), and Oshkosh Defense LLC (military vehicle electrical component supply). A single sub-award to an unnamed prime in September 2025 noted a transducer and motional sensor ASU level component at a 25% milestone payment for long-lead material, indicating Gems Sensors' role in supplying specialized sensors for naval platforms with extended procurement cycles.

Place of performance for all work is Plainville, Connecticut. The vendor holds no government-wide acquisition contracts, GSA Schedules, or multi-agency IDIQs; all vehicle positions are agency-specific or single-award IDCs with DLA. Gems Sensors does not appear in GWAC portfolios or federal schedule rosters in the source data.
