I'm interested in weaponry - we talk a lot about aircraft and what they can and can't do, but we do tend to leave weaponry aside sometimes.
Personally I don't at all expect the RAF to be facing Russian Air Force fighters. However they do sell their stuff to buyers who might turn out to be our adversaries. So how do we see this article, not bothering ourselves about who wrote it or their motives, what do we think of the "facts"?
