The Vulkan Fighter, as it's named by Omochao, is a G.U.N. fighter jet that appears in Sonic Adventure 2 and the Nintendo 3DS version of Sonic Generations. It looks like a bigger Blue Eagle, and is part of the Fighter series.
Sonic Adventure 2
The Vulkan Fighter makes an appearance in Radical Highway, and is triggered by Shadow using the lower route of an incomplete suspension bridge through the updraft. As Shadow reaches the end of the updraft section, it will hover down and fire its machine gun. If Shadow took the higher route across the bridge and down the suspension rails, the jet will not appear.
Sonic Generations (Nintendo 3DS)
The Vulkan Fighter makes a return in the second Act of Radical Highway, the same stage it was originally encountered in. This time around, the ship can be seen hovering stationary in the air at certain points, peppering Modern Sonic with bullets from its machine gun. It is out of the player's reach, and thus it cannot be attacked in this game.
