Abstract:

Arrowshells, superior to standard 3-in.50 rounds as regards muzzle velocity and range, can be adapted to a revised 3 in.50 gun system. The recommended system for initial effort would include a 3 in. smoothbored barrel with loader and fire control revised to handle only arrow rounds. Rifled barrel arrowshells are feasible however, they are desirable only as a means of achieving interchangeability of arrowshells with standard rounds from the same gun. Such a system would require major revision to the automatic loader as well as a more complicated fire control system. Arrowshell designs, however, for both the rifled and smoothbored barrels are presented. Space limitations in the arrow and the high gun acceleration do not permit use of the VT fuze as presently developed. This is not considered a drawback, however, since the arrows lethality is dependent primarily on internal blast rather than flying metal fragments, making a delayed-acting PD fuze preferable to a VT fuze.
