About the company
Greisen Aerospace, LLC is a HUBZone-certified small business manufacturer based in Brunswick, Maine, registered with the federal government since May 2015. The company specializes in precision manufacturing of custom-fabricated equipment and components primarily for the Department of Defense and other federal agencies. Greisen Aerospace operates as a sole proprietorship and limited liability company, focusing on the production of specialized defense equipment, technical support apparatus, and transportation equipment tailored to military and scientific applications. The company has established itself as a reliable supplier to multiple federal agencies through a diverse portfolio of federal contracts spanning nearly a decade.
Greisen Aerospace's federal contract history demonstrates extensive expertise in fabricating specialized military equipment and support apparatus. The company has provided gun tube roller stands to the U.S. Army's TACOM Life Cycle Management Command through multiple contracts, including a $57,000 purchase order awarded in September 2025 and a $56,077 contract for ten units awarded in August 2023. The company has also manufactured spillway gate lifting chains for the U.S. Army Corps of Engineers, including a substantial $6.5 million contract awarded in September 2024 for Lake Barkley Dam and a $274,135.53 contract in June 2024 for Orwell Dam, both designated as total small business set-asides. Additional Department of Defense work includes C-5 engine pylon stands for the Air Force Materiel Command's Warner Robins Air Logistics Complex ($197,250, August 2023), D5 static fire test equipment for Hill Air Force Base ($490,100, January 2021), mounting hardware and frames for Surface-to-Surface Missile Module shipping containers for Naval Sea Systems Command ($232,723.88, September 2022), and shipping containers for Naval Sea Systems Command ($286,984, November 2022).

The company received a single non-defense contract from the National Oceanic and Atmospheric Administration for a marine mammal transport crate ($5,000, June 2024). The majority of Greisen Aerospace's contracts have been designated as total small business set-asides, reflecting the company's status as a certified small business, though some non-set-aside awards have also been received from Naval Sea Systems Command and TACOM.
