Replacement of SR 4990 by Barium Styphnate in the Mk 24 Actuator

Abstract

SR-4990, a single-base propellant used in Navy explosive actuators, is no longer produced. This necessitated a search for an adequate replacement for the SR-4990 in the Mk 24 Actuator. Experimental work was performed with barium styphnate, lead mononitroresorcinate, and two manufactured powders. Candidate materials were first screened using a pressure bomb. Final testing was performed in the Mk 24 Actuator design. Test results showed that of the four candidates, barium styphnate is the best material for the Actuator Mk 24.
