Do the assault ships have drones that can deploy from their decks? If so, why not simply use drones for surveillance, and if necessary, drop a rocket or two.
My son was on the USS Kearsarge, the same class ship (Wasp) as the Boxer and I don't remember seeing or hearing about any drones. They indicated that the USS Bainbridge did use drones but they were small and used for surveillance only, way to small to support any serious weapon.
I'm sure Wasp class ships could support larger drones that carry weapons.
