By contrast, the non-VT fuzed 127mm results showed an expenditure of 2,000 rounds per plane, slightly less for regular attacks (probably related to the swift rate of change of the kamikaze's altitude, which the VT fuze needn't care about). Proximity fuzes are designed for elusive military targets such as aircraft and missiles, as well as ships at U. The near-fuse fuze does not need the projectile to directly collide with the target. Both the 40mm and 20mm guns killed more planes, but their range was much shorter, especially when The document summarizes the design of the XM1158 proximity fuze for the XM1112 Airburst Non-Lethal Munition (ANLM) system.
