1) So, we have to go to an alternate timeline to find a weapon powerful enough to stand an SSD? SSD's have hundreds of turbolaser batteries, ion cannons, proton torperdoe, and concussion missile launcher, of which I'm sure are capable of intercepting a missile. Turbolaser batteries are large enough to envelop an entire X-wing starfighter, so I'm sure it would be powerful enough to wipe out a missile.

In the one of the novel series, Imperial Admiral Zsinj was able to cloak one ship, by placing sattelites around it that effectively cloaked a small area, but this device was destroyed easily by destroying a couple of the sattelites. So, no cloaking technology was ever really discovered that actually worked...
