Whenever I activate my airbrake in GRB when flying the American F-15E, it is completely see through from the rear. Frontal aspect it is visible, but this has been an issue for me for a few months.
it is special cloaking american technology the government doesnt want you to know. We are lucky the chinese and russians were able to give this info to gaijin without the us govenrment knowing. soon all american aircraft will get it to balance out the russian bias
plus you can use the airbrack and the enemy wont see it so you can slow down faster
