Inner Range — 10,000 yards long and 2,750 yards wide, depths vary from 60 feet to 20 feet. The range is a Restricted Area and can be patrolled during tests to eliminate commercial or recreational craft interference with testing. It is in a protected and relatively calm area, thus creating more opportunities for good operating conditions. The range’s close proximity to shore facilities allows quick, low-cost response to emergent situations.

Hole Test Area — 1,760 yards long and 880 yards wide, with a maximum depth of 127 feet.
