It's a USN term afaik. If you are protecting a convoy and
they turn to avoid a sub, you, the destroyer or frigate, needs to
make up considerable ground to get between them, the targets, and
the bad guys. You needed to maintain a flank position between
the two.

I think your sub guys used it in WW2 to move as fast as they could
to get to their target positions. Although, in those days, almost
anything could outrun a sub. But they sure were hard to find
