Sky's defence and security analyst Michael Clarke noted that the site in Faslane is "the biggest military base in Scotland", with around 6,000 to 7,000 people there, "both civilians and military".
"Faslane is probably Britain's most important single installation", he added. "We have seven attack submarines. And if they're all out of maintenance, then this is where they operate from."
