Here are the facts:


The ouroboros was never designed for the military specifically. An EOD version was built and tested but was never offered to anyone.

The ouroboros is used by the Danish Navy on operations (as far as we know) in its' standard form.

The Ouroboros was offerred to the RN. It was not rejected, they considered CCRBs support infrastructure too small for a multi-million £ contract with a 10 year life.

The Sentinel was not designed as a military rebreather and has never been sold to the military. The USN has seen units but currently that is as far as it goes.

There will be an EOD version of the Sentinel in development for this year so this may change.

There are certain enhancements in the Sentinel that although they give required improvement (for the target market) in one area they reduce performance (over Ouroborous) in another. This is the case with Sentinel. It is designed for a different user than the Ouroborous
