Editing RDX (section)

==Name==
RDX is also less commonly known as '''cyclonite''', hexogen (particularly in Russian, French and German-influenced languages), '''T4''', and, chemically, as '''cyclotrimethylene trinitramine'''.<ref name= Davis/> In the 1930s, the [[Royal Arsenal]], [[Woolwich]], started investigating cyclonite to use against German [[U-boat]]s that were being built with thicker hulls. The goal was to develop an explosive more energetic than [[TNT]]. For security reasons, Britain termed cyclonite "Research Department Explosive" (R.D.X.).<ref name="MM-18">{{Harvtxt|MacDonald and Mack Partnership|1984|p=18}}</ref> The term ''RDX'' appeared in the United States in 1946.<ref>{{Harvnb|Baxter III|1968|pp=27, 42, 255–259}}</ref> 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.<ref name= sfb/>
