Summary
Fall 2026 is when the Army expects to start releasing proposal requests for the ISV-Heavy, which acquisition official Jesse Tolleson told lawmakers is being accelerated as a top priority.
60 kW of continuous high-voltage DC power is the centerpiece requirement, alongside 15 kW of 28V DC and 4.8 kW of 120V AC, to turn the vehicle into a mobile energy source for command posts.
Late-March market outreach already opened the competition through a commercial solutions opening, and the Army is steering bidders toward commercially available or non-developmental vehicles with minimal modifications.
606 vehicles are the planned buy over time, including 34 in fiscal 2027; budget documents point to a contract award in September 2027 and first delivery in January 2028.
GM Defense, which supplies the current ISV, has said it will offer a militarized Chevrolet Silverado HD 3500, though Army officials said they expect broader competition.
