Carter Machinery Company, Incorporated

Carter Machinery Company, Incorporated, doing business as Carter Machinery Co Inc., is a for-profit subsidiary of Caterpillar Inc. headquartered in Salem, Virginia that supplies Caterpillar-branded diesel engines, power generation equipment, parts, maintenance services, and technical training to federal agencies as a prime contractor (72% of recent awards) and subcontractor. The vendor operates as an authorized Caterpillar dealer with no SBA set-asides across its prime footprint; it competes full-and-open on all named recent work.

Carter Machinery's capability portfolio centers on heavy equipment maintenance, repair, and parts supply for Caterpillar diesel engines and generators, diesel engine components (fuel systems, injectors, turbochargers, cylinder heads), power generation equipment (alternators, switchgear, control modules), and field service support. Representative prime work includes a $2.1 million power plant upgrade in Baghdad (Bureau of Overseas Building Operations, awarded September 2024); a $983.9 thousand five-year preventive maintenance and load bank testing contract for 17 emergency diesel generators at Martinsburg VA Medical Center (Veterans Integrated Service Network 5, October 2024); a $368.5 thousand delivery order for four Warrant Officer Basic Courses on engine maintenance and hydraulic/pneumatic systems repair (Army Training and Doctrine Command, January 2024); and a $602.7 thousand track loader purchase order (Department of the Army, September 2023). Carter Machinery also holds a $12 million ten-year Blanket Purchase Agreement for heavy equipment maintenance and repair across U.S. Fish and Wildlife Service Region 4 (awarded August 2025) and a $3 million Department of the Army spare parts BPA (October 2023).

Customer concentration splits across defense and civilian agencies. The top five customers by award count account for 50% of recent awards and are led by Defense Logistics Agency Land and Maritime (104 awards, $1.1 million combined potential value), the Department of Homeland Security U.S. Coast Guard (69 awards, $1.7 million), and Naval Sea Systems Command (51 awards, $109 thousand). By potential value, the Department of the Army anchors the portfolio ($3 million across 17 awards), followed by Army Training and Doctrine Command ($2.5 million across 10 awards) and the Department of State Bureau of Overseas Building Operations ($2.4 million across 14 awards). The two rankings diverge moderately: DLA and Coast Guard drive award volume but carry lower individual values, while Army and Army Training and Doctrine Command concentrate larger dollar awards.

Prime contract vehicles include the Naval Sea Systems Command Indefinite Delivery Contract SPE7LX-21-D-0087 (70 task orders), Complex and Non-Complex Maintenance on Surface Combatant and Amphibious Class Ships—Norfolk (12 task orders), Army Indefinite Delivery Contract W91QF-521-D-0001 (6 task orders, $1.4 million combined potential value), and multiple Blanket Purchase Agreements with DLA and Army logistics commands. Activity has grown significantly—18 awards in 2022 to a peak of 108 in 2024, then declining to 61 in 2025 and 14 year-to-date in 2026. Ten awards (combined potential value $1.8 million) face ultimate completion in the next twenty-four months, representing recompete opportunity.

Carter Machinery operates predominantly as a prime: 72% of recent awards are prime contracts and IDVs. On subcontract work, the vendor supplies diesel engine components, generator parts, and equipment rental to major Navy and Army ship repair primes including Atlantic Diving Supply (high-volume supplier of engine injectors, cylinder heads, and turbochargers), Marine Hydraulics International (generator and electrical equipment rental for fleet maintenance), Metro Machine Corp (generator and equipment rental for surface ship availabilities), Huntington Ingalls (generator rental and nuclear support for submarine and carrier overhauls), East Coast Repair & Fabrication (heavy equipment rental for destroyer and amphibious-class ship maintenance), and M.C. Dean (preventive maintenance for power systems and uninterruptible power supplies). Service Contract Inventory data shows minimal SCI-reportable invoicing ($0 prime, across FY2022–FY2025) and fractional FTE presence (0.1 FTEs in FY2025), indicating Carter Machinery's federal work is primarily goods and products rather than labor-based services above the $150,000 SCI threshold.

The vendor's corporate structure includes multiple subsidiary entities carrying the Carter Machinery and Alban Tractor names; the source does not specify distinct operational roles among them. Carter Machinery's market position rests on its exclusive dealer status for Caterpillar products and its logistics advantage as a Virginia-based distributor serving Coast Guard, Navy, and Army installations across the eastern seaboard and overseas.
