I don't know about Virginia but I read a book by one R.V.Jones called "Most Secret War" that was most instructive wrt. $SUBJ in another context. I am sure that they have made great progress meanwhile. NLJDs come to my mind in this context. So they must not emit anything although it is helpfull probably.
