It’s like the ADM-20 “Quail” pretending to be a B-52 bomber.
Take a look at the small thing under the big thing in this picture:

So, yeah — it’s a one-time use thing, although you might be able to recover it and re-attach it, and find a way to refuel or recharge it, so that you can use it again.
It’s bigger than a cruise missile, but smaller than most fighter aircraft of the time. And it’s got all the electronics hardware necessary to be able to pretend to be a much larger ship.
