RDX, abbreviation of Research Department Eplosive or Royal Demolition Eplosive, formally cyclotrimethylenetrinitramine, also called cyclonite, hexogen, or T4, powerful explosive, discovered by Georg Friedrich Henning of Germany and patented in 1898 but not used until World War II.

Q. What is the full name of RDX?
Answer: For security reasons, Britain termed cyclonite as "Research Department Explosive" (R.D.X.). The term RDX appeared in the United States in 1946.

RDX also is known, but less commonly, as cyclonite, hexogen (particularly in Russian, French, German and German-influenced languages), T4, and, chemically, as cyclotrimethylenetrinitramine. In the 1930s, the Royal Arsenal, Woolwich, started investigating cyclonite to use against German U-boats that were being built with thicker hulls. The goal was having an explosive more energetic than TNT. For security reasons, Britain termed cyclonite as "Research Department Explosive" (R.D.X.). The term RDX appeared in the United States in 1946. The first public reference in the United Kingdom to the name RDX, or R.D.X., to use the official title, appeared in 1948; its authors were the managing chemist, ROF Bridgwater, the chemical research and development department, Woolwich, and the director of Royal Ordnance Factories, Explosives; again, it was referred to as simply RDX.
