The TIE Advanced Prototype, designed by Seinar Fleet Systems, was an improvement upon the classic TIE fighter. Not only did it carry a missile launcher, but a hyperdrive, folding panels for improved hanger storage, and shielding. Arguably the most noticeable difference to the TAP when compared to a TIE fighter is the panels themselves, in addition to folding, they also only have solar panels on the inside, allowing for armored external sections....
Armored....
Extra armor...
Added armor plating...
More armor plating than standard TIEs...
Why the **** does the TAP have DECREASED hull compared to a LESSER armored TIE fighter?
