Pioneer Operations Nine Pioneer systems are operated by the Navy and Marine Corps. The Navy's five systems are assigned to VC-6, located at Webster Field, St. Inigoes, MD. The Marine Corps' two systems are assigned to VMU-1 and VMU-2, located at the Marine Corps Air-Ground Combat Center (MCAGCC), Twentynine Palms, CA, and Marine Corps Air Station (MCAS) Cherry Point, NC, respectively. Both Services have one or more deployments under way most of the time. The remaining two systems are located at Ft. Huachuca, AZ (see p. 10). Pioneer continued its ten-year history of mission support in both operational and acquisition arenas. FY 1997 operational activities are tabulated below. They begin with a return from Bosnia and continue with land- and sea-based deployments throughout the year. Meanwhile, several Marine remote receiving station (RRS) teams remained in Bosnia to help with imagery collection, to include monitoring of potential trouble areas during the September 1997 elections. Pioneer's system test and payload support activities are detailed on pages 36 and 39. Pioneer Operational Deployments and Support Pioneer's continuing utility is reflected in the fleet's flying time, increased readiness, and decreased accident rate.
