👉 The APC-12 "Appendix" missiles are a class of short-range, intermediate-range ballistic missiles developed by the United States during the Cold War. They were designed to provide a flexible and cost-effective means of deterring potential adversaries, particularly in the context of the U.S. Southern Command's responsibilities in the Caribbean and Central America. These missiles were notable for their simplicity, with a single-stage design that included a solid rocket motor and a subscale warhead. The APC-12 missiles were launched from mobile launchers, often placed on ships or in fixed positions, allowing for rapid deployment and a wide range of operational flexibility. They were primarily used to counter threats from the Soviet Union and its allies in the region, serving as a deterrent and a rapid response capability.
