I wonder if they are B-61’s?
Heh, those things always looked like Buck Rogers weapons to me. All silver with fins that looked like they were designed back in the late fifties...
I remember when the older B57s were replaced by the first B61s, which was a big upgrade at the time. As an Emergency Actions Team member I spent many hours practicing manual unlocking, disabling, dis-enabling, and other permissive action link procedures on the new B61s. They were pretty sophisticated and had features that are probably still classified so I won’t elaborate. My guess is that these also have some more highly classfied features that we will never be privy to.
