britannic wreck

Considering that Britannic's wreck has been on the ocean floor since November 21st 1916, and to this day she is still considerably intact and retaining her full 94 foot beam, does it decisively prove that all three Olympic Class liners were robust ships that were built to last?

Anyone know how to get the to Britannic via submersible? I located a yacht with Triton submarines that has offered submersible trips to the wreck in the past and I have reached out to them through multiple emails but I can't get an answer.

Is there a Britannic wreck mosaic?

I know that this is not about titanic but rather her well-preserved sister ship but i cannot find answers anywhere so please tell me

how much of britannic has been "eaten" by undersea organisms? or are the organisms just living on the wreck?
