"Large" to one may not be so large to another. I was once a proposal leader on a contract valued at $175M, in 1980's dollars. I thought that was really large. But it was just a piece of a major program contract valued at around $8B. Now THAT's large!

As for info on the value/scope of the contracts, I doubt that you'd find much, if anything. Being for security measures, these are probably classified contracts (SECRET), so little if anything is announced, as any tid-bit of info could reveal too much to adversaries.

FWIW,
