The flak tank gets an extra 20% range boost whan defending, making the range 468.

“ Flak Tanks exist for one purpose: the total annihilation of enemy aircraft. They fire explosive clouds of shrapnel that chew through clusters of enemy air units. Flak Tanks get a 20% range increase against aircraft.” — In-game description
