The concept for the Space and Naval Warfare Systems Center, Pacifc (SSC Pacific) USV was rapid production of a low-cost reliable platform to develop technology for transition to other unmanned assets and programs. The USV platform was chosen for its low cost, ease of systems integration, low maintenance, and similarity in performance characteristics to operational USVs. The platform itself is not the focus of the program but simply a convenient host for the core USV technologies being developed that will then be transitioned to other USV efforts in the Navy.
The platform selected for this development effort is a SEADOO Challenger 2000 sport boat with a jet drive. The platform, configured as an unmanned vessel, is shown in Figure 1. Much of the technology and equipment that make up the basic components of the USV were transitioned directly from on-going unmanned ground vehicle (UGV) programs at SSC Pacific.
