The Service Respirator No. 6 (S6), also known as Respirator NBC S6 No. 1 Mark 1 was a protective gas mask issued to the British Armed Forces. It was developed in the 1950s and issued for general service from 1966 to 1986, when it was replaced by the S10. Currently, the S6 is not used by the British military.
It's usually worn in conjunction with the NBC No. 1 Mk III CBRN protective suit.[2]
History[edit]
The S6 was developed by the Chemical Defence Experimental Establishment (CDEE) from the 1950s and manufactured by Avon Rubber in Melksham, Wiltshire and the Leyland and Birmingham Rubber Company.[1][3] Although made obsolete by the introduction of the S10, production of the S6 continued in Turkey after the adoption of the new mask by British forces. During the widely documented Iranian Embassy Siege of 1980, the S6 is the mask seen being worn by SAS troops.
The Turkish military adopted its own version of the S6 in 1990 with the name SR10 under license by MKEK.[4] SR10 and its newer version the SR10-ST with a D12 drinking tube attached.[5]
