British Aerospace/McDonnell Douglas Harrier GR.Mk5.
The British version of the AV-8B differs from the USMC aircraft in many details, and is designated Harrier GR.Mk5.
It features much British equipment including a Ferranti Inertial Navigation System and moving map display.
The Harrier GR.Mk5 has two 25mm Aden Cannon in underbelly pods, each with 100 round of ammunition. The AV-8B has only one cannon with the starboard pod housing 300 round of linkless ammunition.
sure they can do the same, but they are not nearly as cool or groundbreaking as the harrier. also the others can be flown by some wannabe's, while the harrier has a very high minimum weight for the pilots ballz
