J.R.CUMBERLAND, INC.

J.R. CUMBERLAND, INC. specialized in the manufacturing of glass products from purchased glass, focusing on custom fabrication and assembly processes aligned with defense-grade specifications. Their technical expertise centered on precision glass cutting, tempering, lamination, and edge finishing to meet stringent military and industrial performance standards. Though limited in contract volume, their work demonstrated capability in producing specialized optical, structural, or protective glass components for defense applications, likely supporting equipment enclosures, sensor housings, or vehicle glazing systems requiring durability under extreme conditions. The company’s approach emphasized material integrity and dimensional accuracy, with modifications to existing contracts indicating adaptability in production scaling and cost control within tight federal supply chains. The Department of Defense was the sole known customer, suggesting a narrow but focused engagement with defense logistics or maintenance, repair, and overhaul (MRO) supply networks. Work performed appears to have supported niche hardware systems requiring certified glass components, possibly for radar housings, communication terminals, or armored vehicle applications. The relationship suggests a supplier role embedded within defense production pipelines, likely under direct or indirect prime contractor oversight. The primary NAICS code, 327215, reflects a niche manufacturing vertical focused on transforming raw or semi-finished glass into functional end-use products, distinct from float glass or container manufacturing. This positions the company within the defense industrial base’s specialized materials sector, serving applications where optical clarity, thermal resistance, or impact resistance are mission-critical. Their market positioning was that of a low-volume, high-precision supplier serving specialized defense subsystems. J.R. CUMBERLAND, INC. operated as a small business under the 2L structure, with no federal certifications on record. Located in Temple Hills, Maryland, the firm was positioned within the Mid-Atlantic defense supplier corridor, though recent award data indicates the company is no longer active. Historical performance reflects a narrowly scoped, technically specific contribution to defense glass component supply chains.
