Same with the P2 Neptune ASW aircraft which had equipment with tubes. Also, there the A3 Sky Warrior had equipment with tubes.I got to fly on Nimrods a few times whilst serving in the RAF and was astonished to learn that some of the onboard kit still ran on tubes. That was in the 90's; if it ain't broke don't fix it, and they're pretty robust against EMP apparently.
