Stuffy
can gas up from the Navy's large fleet of boom-equipped tankers. Wait, what?
There are no RAF tanker aircraft fitted with the boom system.
Obviously you don't get humour and irony either!
I'm glad that you understand the difference between range and endurance, perhaps you might now explain why 4 hours on task at 1200 nm from base (that's probably about 2 - 2.5 hours flying time) means the P8 "has a poor endurance for maritime patrol"?
