Astonishing.
The French seem to use the same name for their current 155mm gun whatever vehicle it's mounted on, which is a bit confusing the other way.
Buddy tankers have been around a long time. They're not full-time tankers. New fighters having radars & EW systems which outclass old types with an E prefix isn't new, either. We can't load every type up with everything it can or might be able to do.

The E for F-15, F-16 & F-18 (& now for JAS39) is weird. It started with the F-15E, & IIRC just happened to be the next spare letter for a new mark - & then got used to indicate a major redesign. It's not part of the official designation system.All the modernized F15, F16 and F/A18 should also be getting E prefixes because their new AESA Radars and Electric warfare self defense systems are already far more sophisticated than what was found on previous generations of E/A6 or EF111. As well as R due to the SAR modes.
