High and low temperature reliability tests were conducted on the Pershing missile 309, in the environmental test chamber to determine the systems reliability, ruggedness, and related human factors during conditions of high and low temperature extremes. The Pershing missile 309 consisted of an inert warhead, guidance and control unit, and dummy first and second stage motors elevating launcher, including the cable mast and a set of electrical blankets for the missile. Malfunctions of the warhead fuze during extreme phases of temperature testing proved it unacceptable. Oil pressure on two hydropacks dropped during the low temperature cycles on one hydropack froze, rendering it inoperable. Equipment became too hot to handle comfortably without protective clothing during checkout procedures at high temperatures. During low-temperature test, the warhead section drained off heat generated by blankets covering the guidance and control section, thereby causing the guidance and control compartment to drop below operation temperature. It was recommended that studies be continued on warhead fuze operation at extreme temperatures.
