The A-Wing seems awfully fragile. The X-Wing can take 4-5 hits from a TIE fighter, but the A-Wing is blown apart after only 1-2 hits!
The rebel craft should all be designed so that PCs can feel bad-ass flying them. As it is, it's hard to imagine a PC stepping into one of these deathtraps. Even the sensor jammer doesn't help protect against other silhouette 3 ships, which I believe is what interceptors generally are supposed to go up against.
To make matters worse, they cost even more than an X-Wing, which seems pretty hard to justify.
