Supporting mission readiness for the South Dakota National Guard

The new Watertown Vehicle Maintenance Shop will provide modern maintenance, repair, inspection, and operational support facilities for the South Dakota Army National Guard and the 147th Field Artillery in Watertown.

Designed by TSP, Inc. to improve equipment readiness and long-term mission support, the state-of-the-art military maintenance facility will support ground vehicles, tactical equipment, and weapons systems used by the South Dakota National Guard.

Administrative, training, and operational support spaces

The project includes three primary areas:

• administrative offices
• maintenance work bays
• equipment and operational support spaces

The 5,400-square-foot administration area will include offices for facility management and staff support.

A 1,300-square-foot break room and classroom space will accommodate presentations, instruction, and training activities. Support spaces throughout the facility will provide centralized access to supply and large tool storage, lubrication rooms, and battery storage areas. The building will also include a dedicated bay to support washing and warm-up maintenance operations during harsh South Dakota winter conditions.

Maintenance facilities designed for long-term performance

Maintenance work bays will make up the largest portion of the facility. The 14,800-square-foot maintenance area will feature four full-length work bays and one extended-length bay designed to accommodate larger military vehicles and specialized equipment within the National Guard fleet. The high-clearance maintenance bays will also include two overhead cranes for handling heavy vehicle components and equipment safely and efficiently.

The Watertown Vehicle Maintenance Shop was designed with long-term flexibility to support evolving state and federal missions while maintaining high levels of operational readiness for the South Dakota Army National Guard.

Site improvements include parking connections to the adjacent National Guard Readiness Center to improve facility access and circulation.

Construction began in May 2026 and is expected to be completed in late 2027.
