The NATO Reference Mobility Model NRMM1 is the primary mobility software used by the US Department of Defense, its contractors and NATO countries to evaluate various metrics of proposed vehicle systems for acquisition. The NRMM is a vehicle mobility performance model developed in the 1970s2 that combines mobility related technologies into one comprehensive software package designed to predict the physically constrained vehicle and terrain interaction while operating in both on and off road environments. The empirically based relationships within NRMM are measurements taken from actual vehicles run over a variety of terrains and are geared towards vehicles weighing more than 1500 pounds. As the Army focuses on a lighter, faster and more mobile fighting force, standard military vehicles are decreasing in size with many new ultra lightweight autonomous systems being designed. This fundamental shift in the size and weight of military vehicle systems, questions, the NRMM predictions for on and off road performance. The following paper describes a case study comparing NRMM predictions of the current Future Combat System FCS Small Unmanned Ground Vehicle SUGV, This paper defines required extensions in the existing data fields for the terrain and vehicle to support predictions of SUGVs in NRMM.
