About the company
South East Machine LLC, a Stuart, Florida-based small-business manufacturer, supplies precision-engineered piston rings to the Defense Logistics Agency's Land and Maritime division as a prime contractor under total small business set-asides and full-and-open delivery orders, and manufactures rocket-engine components for the Space Launch System as a subcontractor to Aerojet Rocketdyne.
South East Machine LLC is a for-profit limited liability company and manufacturer of goods classified as a small business. The vendor competes under total small business set-asides on its DLA prime contracts but also accepts full-and-open delivery orders under the same IDCs. Recent prime activity with DLA consists of piston-ring procurement across multiple National Stock Numbers, with individual delivery orders ranging from $1,650 to $24,750. The company holds two active single-award Indefinite Delivery Contracts with DLA Land and Maritime: one awarded May 8, 2024, with a $250,000 ceiling running through May 8, 2025, and a renewal awarded May 1, 2025, with a $250,000 ceiling running through May 1, 2026. Both IDCs anticipate approximately 12 orders annually with a guaranteed minimum of 8 orders. Delivery locations include the DLA Distribution Center in San Diego, California, and South East Machine LLC's Stuart facility.
Customer concentration is narrow and heavily weighted to defense logistics. The Defense Logistics Agency Land and Maritime accounts for all 13 prime awards ($586 thousand combined potential value, 100% of the potential-value total). The National Aeronautics and Space Administration Marshall Space Flight Center represents the remaining five awards, all placed as sub-awards under Aerojet Rocketdyne. Recent prime awards with DLA include a $9,100 delivery order (December 11, 2025) for piston rings under the May 2025 IDC, a $7,700 delivery order (March 13, 2025), a $4,400 delivery order (January 23, 2025), an $8,800 delivery order (January 9, 2025), a $1,650 delivery order (February 20, 2025), and earlier purchase orders for piston rings in 2023 and 2022 ranging from $1,450 to $24,750.
In its subcontractor role under Aerojet Rocketdyne, South East Machine LLC manufactures precision components for RS-25 rocket-engine production restart and Space Launch System recertification, including duct segments, bellows liners, fuel technical air data (TAD) components, and main fuel-preburner liners. Five sub-awards are documented between June 17, 2024, and December 15, 2025. Activity accelerated sharply in 2025 — nine awards across both prime and sub roles — following two awards in 2024 and three in 2023. The vendor's combined dollars obligated ($3.3 million) significantly exceed the combined potential value ($586 thousand), a signal that invoiced work on prior delivery orders under the two DLA IDCs has substantially exceeded their stated ceilings or that earlier contracts have been executed at higher values than the current source captures.
