Nothing really new here. I read about this idea in the sixties. It was a two stage torpedo. The first stage was a 'conventional' electric torpedo that approached stealthily until close enough to launch the rocket powered second stage which closed at high speed. As I recall, the idea of venting gasses to reduce friction on the second stage was discussed at length in the article.

i'll admit i know jack didley about naval warfare.
is there such a thing as a stealthy torpedo?
are these 2 stage types you a reality?
sounds like this could be a devastating.
