This paper will present the results from four series of Fragment Impact (FI) tests on TOW 2B warhead utilizing multiple Particle Mitigation Sleeve (PIMS) configurations. Previously it has been demonstrated that addition a plastic, typically ULTEM® 1000, PIMS reduces sensitivity munition to FI threat. The mechanism by which is reduced reflection shockwave at interface between and case material. munitions this protection scheme applied previously use PBXN-9 as main fill explosive are therefore easier protect using single component than 2B, uses LX-14 fill. more sensitive PBXN-9, requires additional material in shotline reduce shock pressure via reduction velocity, breakup incoming fragment, PIMS. test demonstrate can be protected plastic combination with second layer hard spaced break fragment slow down prior impact
