“Realistic training ranges are one of the most valued assets the military has in preparing its personnel for their missions. Realistic training requires access to areas and environments that closely match the locations where the military may face combat or complex situations” – Brian J. Lepore, Director, Defense Capabilities and Management

The system provides U.S. Marines with temporary, transportable radio capabilities for post-disaster, infrastructure restoration and other missions.

Targets on the lake will allow Scoring Systems Engineering personnel to assess system accuracy in a controlled environment over water as they prepare for technical refresh of Weapon Impact Scoring Sets (WISS) at naval tactical training ranges.

NSWC Corona designed the self-contained solar power systems for a pair of range microwave towers in advance of installation to minimize training schedule impact.

The Range Systems Engineering Department builds, instruments and supports DoD test and training ranges worldwide. The department provides systems engineering and technical guidance to range commanders and managers across the Navy and Marine Corps and serves as the technical agent for operation, maintenance and engineering of Navy and Marine Corps Tactical Training Range (TTR) systems. RS has personnel assigned throughout the world and has offsite offices across the country, including a major installation on Naval Weapons Station Fallbrook, located just 60 miles south of Corona by Marine Corps Base Camp Pendleton, that specializes in expeditionary systems engineering of ammunition and weapons for the Marine Corps, Navy and Army to improve performance through systems, test, reliability and warfighter-scientist integration. NSWC Corona has a long history of designing and operating range systems, to include the famed Top Gun school for fighter pilots designed to improve air-to-air combat proficiency. “We help the Fleet get better every day,” said Dan Bergstrom, Range Systems Engineering Department Head. “There is a lot of pride in the department but we all know we are part of a much larger team.” The department has 335 civilians and 1,165 contractors based worldwide with nearly 300 projects ongoing at any given time.
