About Ridge Machine Shop Inc.
Ridge Machine Shop Inc., a for-profit machine shop based in Halifax, Pennsylvania, supplies precision-machined industrial hardware and components to the Department of Defense as a prime contractor on a high-volume, small-order basis under total small business set-asides. The vendor competes exclusively under small business reserves and holds no parent vehicle positions; all 474 recent awards are individual purchase orders, not task orders against IDIQs or GWACs.
Ridge manufactures fasteners, mechanical hardware, hydraulic and pneumatic components, sealing products, and specialized machined assemblies in direct support of naval logistics and fleet readiness. Representative work includes a $4,794 purchase order from Naval Supply Systems Command in April 2026 for precision-machined axle-related hardware; a $29,326.50 order in February 2025 for a hydraulic cartridge meeting military configuration-control and shelf-life standards; a $21,088 contract in June 2024 for shear bolts; and ongoing orders for cap screws, self-locking fasteners, o-rings, springs, connectors, brake valves, and specialized components such as captive bolts and lock pins. All work is performed at the Halifax facility on firm fixed-price terms.
Customer concentration is extreme and narrow. The Naval Supply Systems Command (NAVSUP) accounts for 419 of 474 awards (88% of volume) and $1.5 million of the $1.7 million combined potential value. The Defense Logistics Agency Land and Maritime division represents 31 awards ($189 thousand), Aviation represents 9 awards ($15 thousand), and the Troop Support Hardware division represents 3 awards ($6 thousand). NAICS concentration skews toward guided-missile propulsion-unit parts (62 awards), miscellaneous general-purpose machinery (43 awards), machine shops (38 awards), and fastener manufacturing (37 awards). PSC concentration shows heavy weight in launchers and guided-missile equipment (144 awards) and specialized missile maintenance and checkout equipment (99 awards), signaling that Ridge's work supports submarine-based strategic missile system supply chains — consistent with cited contracts for components destined to Strategic Weapons Facility Pacific and the Trident Refit Facility.
Activity has declined from 43 awards in 2022 to 22 in 2024 and 22 in 2025, with only 4 awards recorded in 2026 to date. The recompete cliff is minimal: only 1 award with ultimate completion in the next twenty-four months carries $5 thousand in potential value. Obligated dollars ($2 million) exceed combined potential value ($1.7 million), indicating the vendor has invoiced more than the contracts' stated ceiling values — a pattern typical of small-order, as-needed supply relationships where actual spend overshoots initial estimates.
Ridge operates as a 100% prime contractor with no recorded subcontract footprint. The vendor has been registered in the System for Award Management since 2001 and maintains continuity as a long-standing Navy supplier, but the sharp year-over-year decline in order volume and the absence of forward pipeline visibility create exposure to procurement cutbacks or consolidation in the naval supply chain.
