E-40 Egg Fortress

Following the subsequent destruction of his original headquarters, Dr. Eggman reappeared from under the wreckage with a new mobile air fortress. Purple in color, the ship was designed with a trio of massive drills, one on the prow and two on the wings. A retractable bridge and three gigantic rocket engines added to this ships appearance. Armed with a battery of flak cannons and missile launchers, the Egg Fort also carries a pair of high-powered Egg Blasters, which in it's initial usage nearly destroyed the X-Tornado outright. After numerous defeats and repair work, Eggman retired the Egg Fort in Episode 20 in favor of the Egg Fort 2. The Egg Fort was resurrected in Episode 47, having been commandeered by GUN forces into a airship of their own to combat Eggman's new Egg Battleship. It is uncertain what happened to the craft after the assault on the equator.
