Titan was not a submarine…it was a submersible.
The difference is a submarine has enough power to leave port and come back to port under its own power, according to the experts.
A submersible like the Titan has very limited power reserves so it needs a mother ship that can launch it and recover it.
This means it does not, unlike a submarine, have the power to dive down to the bottom of the ocean and come back under its own steam.
That alone would indicate, the whole thing was doomed from the start…a suicide mission.
The mother ship Polar Prince escorted Titan to Newfoundland, which is the nearest point to the Titanic.
The mothership lost contact after two hours, so that is another telling fact.
