About Southern Gear & Machine Inc.
Southern Gear & Machine Inc., a veteran-owned, SBA-certified HUBZone small business located in Miami, Florida, manufactures precision-machined mechanical power transmission components — spur gears, bevel gears, antibacklash gears, helical gears, sprockets, shafts, and gear assemblies — as a prime contractor (86% of awards) and subcontractor to major defense primes. The company operates as a for-profit manufacturer under primary NAICS 333613 (Speed Changer, Industrial High-Speed Drive, and Gear Manufacturing) and PSC 5340 (Gears, Pulleys, Sprockets, and Transmission Chain).
Customer concentration is extreme and narrowly focused on defense logistics. The Defense Logistics Agency Land and Maritime accounts for 436 of 561 total awards (78%) with $4.6 million in combined potential value — the vendor's entire active footprint is built on a single-award indefinite delivery contract with DLA L&M valued at $350,000 (HUBZone set-aside, awarded January 8, 2026, expiring January 12, 2026) and a prior single-award IDC valued at $250,000 (total small business set-aside, expired April 2025). The remaining 88% coverage of awards flows through a handful of secondary customers: the Department of the Army Materiel Command Aviation and Missile Life Cycle Management Command (15 awards, $205 thousand), Department of the Navy Naval Sea Systems Command (20 awards), and Department of the Army PEO Ground Combat Systems (13 awards). This customer concentration exposes the vendor to acute recompete and runway risk — only one award completes within the next twenty-four months, and the active HUBZone IDC with DLA expires in January 2026 (in effect, already expired as of this writing in July 2026).
On the prime side, Southern Gear supplies DLA depots nationwide through a consistent stream of firm-fixed-price purchase orders for gear components ranging from $1,300 to $103,940. Representative prime awards include a $103,940 order for spur gears (March 11, 2025), a $62,164 order for spur gears (January 21, 2025), a $64,471 total small business set-aside for spur gears (October 9, 2024), and a $61,825 order for rigid shaft couplings (May 22, 2023). Most DLA awards carry no set-aside designation, though several cite total small business set-asides. Award volume has trended upward year-over-year (23 awards in 2022–2023, 51 in 2024) but dropped sharply to 26 in 2025 and only 7 in 2026 — a signal of declining order flow.
Southern Gear's subcontract footprint anchors it to four major defense primes: BAE Systems Land & Armaments (material and service deliveries on Bradley A4 production, MK 45 upgrades, and self-propelled howitzer systems), Lockheed Martin Corporation (gear pinions and spur gears for HIMARS, M270A2 MLRS, and Apache M-TADS/PNVS modernization), Hamilton Sundstrand Corporation (drive gear clusters), and General Dynamics-OTS (gear assemblies for ammunition drums and guided missile directors). Raytheon Company receives sub orders for precision-machined gears supporting CIWS production and MK 144 guided missile launcher systems. These sub relationships represent ongoing, high-volume exposure to Army and Navy platforms. The vendor also works as a sub to Raytheon on Navy programs and to Electric Boat Corporation on submarine systems work.
Regarding parent vehicles, Southern Gear operates under multiple Army IDIQs: W56HZV22D0083 (10 task orders), W58RGZ23D0011 (6 task orders for Apache TADS/PNVS), and W52P1J17D0043 (5 task orders). The vendor also holds positions on Navy vehicles N0002420D5109 (3 task orders) and Army SPM7A208D5L91 (3 task orders, $30 thousand combined potential value). These vehicles represent the structural foundation for sub work delivery to prime contractors.
The vendor has maintained federal contractor status since 2002 SAM.gov registration. Activity reflects strong historical alignment with DLA but accelerating concentration risk — the loss of the expiring HUBZone IDC and absence of visible pipeline beyond DLA creates acute recompete exposure. Award dates spanning 2022–2026 show peak volume in 2024, with sharp pullback in 2025–2026, suggesting either customer inventory management or competitive loss.
