The type designation does not use any spaces or hyphens (so "M-16" and "M 16" are incorrect). An example given is "PROJECTILE, 105 MILLIMETER: HE, rocket assisted, M547A3". The Approved Item Name is "PROJECTILE, 105 MILLIMETER"; the extended modifier(s) "HE, rocket assisted", and the type designation is "M547A3".
HFCs replaced older chlorofluorocarbons such as R-12 and hydrochlorofluorocarbons such as R-21. [2] HFCs are also used in insulating foams, aerosol propellants, as solvents and for fire protection. They may not harm the ozone layer as much as the compounds they replace, but they still contribute to global warming --- with some like ...
If released, HFCs stay in the atmosphere for decades and both PFCs and SF 6 can stay in the atmosphere for millennia. The total atmospheric concentration of F-gases, CFCs, and HCFCs has grown rapidly since the mid-twentieth century; a time which marks the start of their production and use at industrial scale.
Prior to the creation of the DHFCS, the Royal Air Force (RAF) and Royal Navy (RN) operated their own independent high frequency (HF) communications systems. The RAF's Strike Command Integrated Communications System (STCICS), later known as Terrestrial Air Sea Communications (TASCOMM), operated from six sites within the UK whilst the RN system had twelve sites.

As a result of CFCs contributing to ozone depletion in the upper atmosphere, the manufacture of such compounds has been phased out under the Montreal Protocol, and they are being replaced with other products such as hydrofluorocarbons (HFCs) and hydrofluoroolefins (HFOs) [1] including R-410A, R-134a and R-1234yf.
