About Mahr Inc.
Mahr Inc., a large, foreign-owned manufacturer of precision dimensional metrology equipment based in Providence, Rhode Island, operates exclusively as a prime contractor (100% of awards) supplying specialized measurement instruments, calibration services, and equipment upgrades to the Department of Defense and federal measurement standards agencies on a full-and-open basis — the company holds no SBA set-aside designations across its federal portfolio, with the sole exception of one recent Total Small Business purchase order from the Defense Logistics Agency for air comparator gages.
Mahr's capability footprint centers on precision gage systems, calibration services, and measurement equipment maintenance. Representative work includes a $890 thousand firm fixed-price definitive contract from the Air Force Materiel Command to upgrade twenty Short Gage Block Comparator systems at Wright-Patterson Air Force Base (August 2021); a $268.8 thousand delivery order from Naval Sea Systems Command for dial indicator calibrators supporting Navy shipyard and depot maintenance (September 2021); a $91.5 thousand Army Primary Standards Laboratory purchase order for commercial factory repair, recalibration, and software upgrade of a Model 828 CIM Universal Length Measurement Machine (May 2025); and a $215.8 thousand Defense Logistics Agency Land and Maritime purchase order for fourteen air comparator gages under Total Small Business set-aside (March 2026). Additional work spans aircraft gage sets, roundness testers, circular geometry machines, CNC machine repairs, and software upgrades across Defense and civilian metrology customers.
Customer concentration is heavily weighted to defense metrology operations. The top five customer categories account for 73% of combined potential value, anchored by the Air Force Materiel Command (nine awards, $5.4 million combined potential value; plus a separate Wright-Patterson Lifecycle Management Center line with seventeen awards totaling $3.3 million), the Naval Sea Systems Command (24 awards, $2.2 million), the Army Aviation and Missile Life Cycle Management Command (27 awards, $1.6 million), and the Army TACOM Life Cycle Management Command (13 awards, $1.1 million). The Department of the Air Force leads by award count (61 awards) and the Department of the Navy by volume of named sub-commands. Mahr also places work with the Naval Air Warfare Center, National Institute of Standards and Technology, and Defense Contract Management Agency.
Mahr operates under five named indefinite delivery vehicles, the largest being FY233306D0003 with ten task orders totaling $1.6 million combined potential value, followed by F4160889D1389 (four task orders), N6426720D0037 (two task orders, $299 thousand), and single-task IDVs under Army and Air Force frames. The majority of Mahr's awards are discrete purchase orders rather than task orders under larger vehicles.
Award velocity has declined from nine awards in 2022 to one in 2026 year-to-date, reflecting a contraction in federal buying activity; however, the source reports a 45-year award history dating to 1980. Only one award is scheduled to complete within the next twenty-four months, presenting minimal near-term recompete exposure. Work is performed at Mahr's Providence, Rhode Island headquarters and at customer sites including Wright-Patterson Air Force Base, Tinker Air Force Base, Rock Island Arsenal, and overseas locations such as Jubail, Saudi Arabia, under Foreign Military Sales arrangements. The company's NAICS footprint aligns tightly with precision instruments manufacturing (117 awards under the measuring, displaying, and controlling instruments category) and inspection gage tools (60 awards), with minor exposure to aircraft parts and equipment repair work.
