Just came across this in the September issue of DRDO's monthly newsletter. The Navy has put the DRDO-developed Submarine Escape Set (SES) through extensive trials and accepted the product. Developed by the Defence Bioengineering and Electromedical Laboratory (DEBEL), the SES consists (see photo) of a hydrosuit and closed-circuit breathing apparatus.According to the DRDO newsletter, "This set can be used for escape from an abandoned submarine from a depth of 100m." The hydrosuit, made from rubberised buoyant fibre, floats the submariner to the surface -- no surface decompression necessary. Built for tropical condictions, and apparently less cumbersome than hydrosuits currently in inventory, the suit is geared with automated breathing apparatus. Pretty cool, this.
