The replacement Canadian Underwater Mine Warfare Apparatus (CUMA) system will provide the RCN with the capability to investigate underwater contacts to a depth of 81 Metres for 20 minutes (time on task) without incurring decompression stops. The system will use a mixture of 3 different breathing gasses – TRIMIX, instead of the current Helium, Oxygen mix (HELIOX). The re-breather will feature an emergency Bail-out System, Auxiliary Gas Supply and communication and tracking system will be incorporated into the Canadian Underwater Minewarfare Apparatus.
