Army resumes testing for its family of medium tactical vehicles January 21 Upgraded FMTV, both four and six-wheel variants, have resumed government testing after running into problems requiring some redesign in 2020. (Oshkosh) WASHINGTON — The Army has resumed product verification testing for the latest variant of its Family of Medium Tactical Vehicles (FMTV), Wolfgang Petermann, project manager of transportation systems in the Program Executive Office Combat Support & Combat Service Support, told Defense News. The A2 variant ran into problems during PVT testing and the Army program office stopped the effort about 50,000 miles into a 170,000-mile reliability test in May 2020, Petermann said. The upgraded A2 variant include an adjustable suspension system, increased payload, improved ride quality, electronic stability control, and an underbody protection kit.
