You think you do, but you're a huge sitting duck while you're up there.
Still, if you can sneak far enough away, it could be useful.
One of the fights it became 4 vs. me, after I had managed to take down three the last one was far away and we had a good two minutes+ before contact. Searched for the supply ship but could only find the other team's, and lost the last sliver of health I had from a collision with the last sub .
