About the company
Southwest Greene International, Inc. is a woman-owned manufacturer of metal-stamped ammunition components and ammo strip-links that operates exclusively as a subcontractor to large defense primes, supplying lightweight 30mm cartridge assemblies, closures, and related ordnance components to the Department of the Army and the Department of the Navy across sixteen sub-awards totaling $5.6 million obligated.
Based in Oceanside, California, Southwest Greene is a for-profit manufacturer classified under NAICS 338220 (Ammunition, except Small Arms Manufacturing) with a pure subcontractor posture — all sixteen awards in the source are sub-awards; the vendor holds no prime contracts or IDVs. The woman-owned business designation appears across its federal profile but does not anchor the award footprint to set-aside vehicles; all work flows through prime contractors' compliance and contract vehicles rather than through woman-owned-business set-asides.
The customer base is narrow and defense-focused. The Department of the Army Acquisition Support Center, PEO Ammunition accounts for 14 of 16 awards, with the Department of the Navy Naval Sea Systems Command accounting for the remaining 2, yielding 100% concentration against two military customers. The prime contractor footprint centers on two large defense industrial primes: General Dynamics Ordnance & Tactical Systems, Inc., which anchors 3 sub-awards for miscellaneous M789 and M788 cartridge components and ammo strip-links, and Northrop Grumman Systems Corporation, which holds 4 sub-awards spanning metal-stamped closures, crowns, and stampings for the same 30mm lightweight cartridge families. Southwest Greene's capability stack — metal stamping, closure manufacturing, and assembly of lightweight 30mm high-explosive dual-purpose (HEDP) and target-practice (TP) ammunition — is specialized to ordnance production and does not extend to broader manufacturing or systems integration.
Activity has been episodic. The vendor recorded two awards in 2021, one each in 2022 and 2023, then four awards in 2025, with one award in the first quarter of 2026. The most recent award (January 2026) was a metal-crown and closure stamping sub from Northrop Grumman for the M789 HEDP cartridge. Four sub-awards fall under Indefinite Delivery Contract W52P1J18D0093 (8 task orders total), with the balance scattered across three other Army and Navy IDCs. No recompete cliff is identified in the source, and the episodic award pattern suggests work is driven by customer ammunition demand signals rather than by contract option renewals at fixed intervals.
