Commentary: J-20 gun armament
Background:
The Chengdu Aircraft Company (CAC) J-20 5th generation stealth fighter made its first flight on 11th of January, 2011.

EA-18G Growler, an electronic warfare variant of the F/A-18F Super Hornet. Many minor differences exist between the two, with one of the more significant ones being the removal of the F/A-18F’s internal gun on the EA-18G
