U.S. officials are certain the rocket fuel used by North Korea in its Hwasong-12 intermediate-range ballistic missiles came from China and Russia, and now it may be too late to stop Kim Jong-un’s advances.
This fuel, unsymmetrical dimethyl hydrazine, or UDMH, is extremely expensive to manufacture but is appealing for use in military rockets because it can be kept loaded in fuel systems for long periods. It is used primarily in missiles deployed by Russia, China, and India, particularly in the Russian Proton and Kosmos-3M and the Chinese Long March-2 space launch rockets.
