Abstract:

This document analyzes landing craft vulnerability to enemy action, and provides methods for the combination of all vulnerability factors into usable attrition rates. Vulnerability of landing craft to enemy action has been estimated using two complementary methods. The first, which has wide applicability, estimates the extent to which a craft is exposed to attack or damage as a function of exposed area and time, and considers all types of weapons at all ranges but does not consider accuracy in detail. It provides values that are proportional to the number of fragments that might be taken during one round trip to the beach. Provision is made for extension of the method to more elaborate models and for the conversion of the vulnerability values to attrition rates. The second method of narrower applicability is a probability analysis of the craft in a very specific artillery environment. It provides values for the probability of a hit, the probability of a kill, and attrition rates, and also provides a method for estimating the downtime resulting from attrition. Results are presented for seven out of over 40 craft that were examined in detail. Data are included on craft unloading times and artillery shell fragmentation.
