New UNSC air vehicle?

I keep seeing things all over the web about a new UNSC “airship” in halo 4. I have no idea where people are getting this from. Can anyone provide a link to a picture or video?

I would also like to see it.

From what Ive heard it is called the AV-22 Sparrowhawk/Sparrow
Originally in Halo Wars.
Sparrowhawk

That would be excellent!
