About the company
Tower Systems, Inc., doing business as Minnesota Tower Systems, is a woman-owned small business based in Watertown, South Dakota that provides tower installation, maintenance, repair, and antenna services to federal agencies as a prime contractor (61% of recent awards) and as a subcontractor to defense primes. The vendor holds SBA certification as a Women-Owned Small Business and competes predominantly under WOSB set-asides on its prime work; the most recent prime award, a $43,950 firm fixed-price contract from the Western Area Power Administration awarded March 12, 2026 for urgent repairs to the Bijiou Repeater and Lake Andes Turnbuckle facilities in South Dakota, was issued under WOSB sole-source designation.
Tower Systems' capability portfolio centers on telecommunications and power infrastructure work. Prime work spans tower re-lamping, inspection, and maintenance across military and civilian facilities — a $43,670 definitive contract with the Air Force's Air Combat Command for tower re-lamping at Minot Air Force Base (completed October 2023), and a $5,900 purchase order from the National Oceanic and Atmospheric Administration for tower inspections at the Barrow Observatory in Utqiagvik, Alaska (completed July 2023). The vendor also performs subcontract work on antenna installation and communications equipment services under defense primes including Rockwell Collins, Northrop Grumman Systems Corporation, and Amentum Services, Inc. Recent sub-award activity includes multiple antenna installation tasks on the Rockwell Collins IGF TCTS Increment II program at sites in South Carolina, Florida, and Georgia (March 2025), maintenance and operation services for the Atlantic Undersea Test & Evaluation Center under Amentum (November 2025), and weapons systems modeling and simulation fiber services under Mantech TSG-2 Joint Venture (May 2025).
Customer concentration spans twelve agencies, though the top five (Department of Homeland Security Customs and Border Protection, Department of Energy Western Area Power Administration, Department of the Air Force Air Combat Command, Department of Justice Federal Bureau of Investigation Headquarters Division, and Department of Commerce National Oceanic and Atmospheric Administration) account for 78% of combined potential value. CBP anchors the dollar profile with three awards totaling $675,000 in combined potential value. The Department of the Navy Naval Air Systems Command Naval Air Warfare Center leads by award count with four awards. Two parent vehicles support recent task orders: One Acquisition Solution for Integrated Services (three task orders) and the Information Analysis Center Multiple-Award Contract (one task order). The vendor's award activity shows volatility — one award in 2018, five in 2023, one in 2024, five in 2025, and one in 2026 — with combined potential value across all twenty-three awards (prime and sub) totaling $1 million and combined dollars obligated at $1.1 million.
Tower Systems operates primarily through its parent entity, with one named subsidiary, Tower Systems South, Inc., also designated as a woman-owned small business. Service Contract Inventory reporting covers minimal federal service activity — a single SCI record from fiscal year 2022 in a subcontractor role, reflecting only a narrow slice of the vendor's federal work and no reliable basis for characterizing workforce scale or rate posture across the broader prime and sub footprint.
