Technical Evaluation of the 8-Inch Major Caliber Lightweight Gun Mount, Mark 71 Mod 0
Abstract
The evaluation included determining performance parameters of the laying and loading systems, electrical power consumption levels for the mount, checking misfire and regunning provisions, a safety analysis, and firing tests. During the firing tests: (1) The mount proofed satisfactorily; (2) Rate of fire of the mount was determined to be 11.7 to 12.6 rounds per minute; (3) Accuracy data gathered indicate that round-to-round accuracy was satisfactory; although, a new 8-inch range table is recommended; (4) Barrel life and velocity loss data were too limited to be conclusive, but do not indicate barrel wear and velocity loss to be excessive; (5) A gun blast profile for the gun was established as being slightly less severe than that of an 8-inch bag gun; (6) Smoke and carbon monoxide measurements taken indicate it would be unsafe to circulate the air from within the mount to a ship's manned space during firing, or for maintenance personnel to enter the mount after firing until the mount is purged. Problems were encountered which required minor design changes. Performance of the mount was judged acceptable and certification for release to operational evaluation was recommended.
