Additionally, the company has received contracts from the U.S. Army's Communications Electronics Command for cover assemblies and mounting plates, as well as from the Joint Munitions Command for sabot production. The company's contract values have ranged from approximately $4,000 to $152,000 per individual purchase order, with the majority of awards designated as total small business set-asides under NAICS code 332710 (Machine Shops). Notable recent contracts include an $96.9K award for flared base group antenna assembly components (August 2025), an $80K cartridge case production contract (August 2025), a $157.6K MK 22 hardware award (July 2025), and a $129.9K contract for Tomahawk lead discs with delivery extending through 2027. The company's contracts are typically firm fixed-price purchase orders and delivery orders with completion dates ranging from several months to multiple years, reflecting both immediate procurement needs and longer-term supply relationships.

Constellation Machining holds a single-award Indefinite Delivery Contract (IDC) valued at $294,600 with the U.S. Army's Joint Munitions Command for the production of sabots, which are critical components for military munitions and weapons systems.
