Mack Defense announces JWF Defense Systems (JWFDS) will provide the armored cab system for the M917A3 Heavy Dump Truck (HDT) contract the U.S. Army recently awarded to Mack Defense. JWFDS will be responsible for fabricating and painting the complete armored cab system, which will then be installed by Mack Defense. 

“JWFDS has an excellent reputation in the industry when it comes to working with armor fabrication to support military vehicles,” says David Hartzell, President of Mack Defense. “We’re pleased to be able to partner with JWF, and we look forward to delivering reliable Mack vehicles that meet and exceed the Army’s high standards.”

Mack Defense was awarded the U.S. Army contract in May 2018 to provide up to 683 HDTs. Mack’s winning bid was based on the company’s commercially available Mack Granite axle forward model. A key differentiator between the commercial offering and the HDT is the latter requiring a force protection capability.

The armored cab was designed by Tencate Advanced Composites of Morgan Hill, CA, and will be manufactured by JWFDS in Johnstown, PA, and will be fitted with Jankel BLASTech seating. Work has already begun and is expected to continue through May 2025.

“We are pleased to enter into this agreement and work with Mack Defense, another Pennsylvania-based defense contractor,” says Chief Operating Officer John Polacek of JWFDS. “This represents another long-term contract for vehicle builds and extends JWFDS’ capability in manufacturing armor-based vehicles.”
