1. Initial Salvo Error
Of the ~50 main battery missions fired by
USS New Jersey on San Clemente during the week of 27 July 1968, 16 had an estimated Initial Salvo Error (ISE).
All but three of the 16 reported missions were fired at ranges comprised between 8,000 and 12,000 yards. For those 13 missions, mean ISE was 115 yards (std dev. = 71 yards).
Three of the reported 16 missions were fired on 30 July 1968 at ~20,000 yards ranges. For those 3 missions, mean ISE was 268 yards (std dev. = 103 yards).
2. Cratering Effectiveness
During the week of 27 July 1968,
USS New Jersey also fired four rounds (either quick or base detonating fuzing) to obtain the dimensions of the craters produced by 16" HC projectiles.
The observed craters were shallow (max. depth at the center of 3 feet) and small (max. 27 x 7 feet), contrasting with the larger craters later observed in Vietnam.
This was probably due to the difference in soil consistency between the hard desert soil of San Clemente and the wet soil of Vietnam.
