The name comes from the remora, a small fish that can attach itself to larger marine life, and has the backronym "Really Excellent Method of Rescuing Aussies".
[1][2] Remora was constructed by OceanWorks International of North Vancouver, British Columbia for the RAN, based on a diving bell.
[5] The entire setup (Remora, control centre, and recompression chambers) could be transported by road or sea, or loaded into C-130 Hercules aircraft.
[2] Although repairs were completed, Remora did not reenter service as the Det Norske Veritas classification society refused to certify the submersible; the launch and recovery equipment did not meet updated safety standards.
[2] To cover the capability loss, the Department of Defence arranged for the British LR5 submersible to be flown to Australia if submarine rescue was required.
