About Group Four Transducers Inc.
Group Four Transducers Inc., a for-profit manufacturer of precision calibration equipment and load-cell systems headquartered in East Longmeadow, Massachusetts, operates as a prime contractor on defense supply contracts with no participation in federal IDVs, GWACs, or set-aside programs. All sixteen federal awards in the source are firm fixed-price or purchase order transactions under full-and-open competition, with combined potential value of $4.3 million across a five-year span.
The vendor's customer footprint is highly concentrated with the Department of the Navy. The Naval Supply Systems Command (NAVSUP) accounts for 13 of 16 prime awards and $4.2 million of the $4.3 million combined potential value — effectively 100% of the vendor's Navy exposure. The Defense Logistics Agency Aviation holds 2 awards valued at $34 thousand combined, and the Naval Sea Systems Command holds 1 award for $13 thousand. NAICSCAT concentration aligns with the calibration-equipment core: Physical Properties Testing and Inspection (PSC 4920, 8 awards) and Aircraft Maintenance and Repair Shop Specialized Equipment (PSC 4931, 7 awards) dominate the procurement profile.
Representative work includes a $2.27 million definitive contract from NAVSUP awarded April 14, 2025, for manufacture and delivery of calibration kits and cabinets (completion November 20, 2025); a $1.08 million definitive contract from NAVSUP awarded October 6, 2023, for calibration kits and cabinets (completed June 15, 2024); and a $499 thousand definitive contract from NAVSUP awarded February 27, 2023, for similar calibration kits (completed August 1, 2023). Recent purchase orders include a $63 thousand calibration unit from NAVSUP (awarded February 10, 2026, completion July 1, 2026) and a $5.6 thousand calibration cell from DoD Aviation (awarded November 17, 2025, completion June 29, 2026). All awards carry no set-aside designation. The vendor performs all work at its East Longmeadow facility and has maintained active federal registration since August 2015.
Activity trajectory is flat. Awards averaged 2 per year from 2021 through 2023, dropped to 2 awards across 2024 and 2025, and 1 award in 2026 year-to-date. The vendor operates exclusively as a prime contractor with no subcontract footprint. The source does not identify this vendor as holding 8(a), HUBZone, SDVOSB, WOSB, or other SBA designations, nor does it indicate minority or women ownership.
