What is a SIGINT loop? B1 Doesn’t collect that, unless there is a assigned bird up. Basic training, probably refueling practice.
SIGINT Loop is a series of circles made over a target to collect electronic signals. (sorry for being pedantic, you know this).
I just see patterns and apply general knowledge.
These loops appeared to tight to be re-fueling or such practice. Plus, there wasn’t a K35 nearby.
Yes, B1 isn’t fitted for SIGINT...officially?
MILINT has some Dornier turbo-prop “shuttle” planes flying SIGINT on occasion.
