    The SDBA armed forces rebreather

    1): http://www.therebreathersite.nl/Zuur...t_sdba_mk5.htm

    2) https://en.wikipedia.org/wiki/SDBA

    Is this breathing set still being made?

    Link 1 says that it could be supplied with a fullface mask :: does anyone have a picture of that fullface mask?

    What rebreather do British armed forces divers (combat divers and work divers) use now?

    The US uses the MK-25 CCR for combat swimmers. It is a chest mounted 100% O2 system, with dragger DSV so kind of limited in its application. They use standard masks no full face.
    Most deep stuff is done open circuit as far as RECON/MRF is concerned. The Navy side a bit more dynamic, the ISC Meg version MK-28 is still at Experimental Dive Unit, I have not heard of it being in application yet. Other than that the KB helmet is used for tethered ops/salvage.

    Re: The SDBA armed forces rebreather

    I websearched for "MK-25 CCR" and I found 2 pages, one being http://www.therebreathersite.nl/08_W..._2005_2006.htm , and in a thanks list it says about somone: "... / Rebreather: LAR-5 / Organization: U.S .Navy Diver / PADI / Level: MK-16, MK-25 CCR/UBA / ...". Is the MK-25 CCR the same as the LAR-5? http://www.therebreathersite.nl/Zuur...eger_lar_v.htm

    The SDBA armed forces rebreather

    On the VMS facebook page there was a photo of a bunch of new VMS Sentinels being shipped for a military contract. It didn't specify what military however.

    I suspect that the SDBA rebreather


    https://en.wikipedia.org/wiki/File:A...ebreathers.jpg



    went out of use and sale because armed forces found that when used as a frogman's set for furtive infiltration, climbing over walls and edges of quays and gunwales of boats was much impeded by the big cylindrical absorbent canister across the front of the lower abdomen. (And it would also have caused hydrodynamic drag in swimming.)
