Actually, depends on your POV, but A-Wings were possibly even at Yavin in a prototype "spearhead" form (See the ICS books, and X-Wing.
), so I'm not sure... I'm ok with it maybe... I've always viewed them as pre-ANH vehicles, but barely pre-ANH. The XW and YW fighters were the backbone till the battle of Yavin.... and I've always envisioned like dozens of other fighter types used, by any number of cells and outposts.
I even have toyed with a repaint (and some reworking) of the V-19 to a Rebel deco, but taking it a step further and stripping it down in some ways, and armoring it up in others, to make it look like it fits in with another TCW era ship that's seeing new life in the Alliance... I figure the V-19's were AW's when AW's weren't widespread or even designed yet. I figure the V-19's were early "intereceptors" for the Alliance... no Hyperdrive, but shields and a lot of them in surplus around the galaxy... Kinda like the YW.
Anyway, that all always kinda tied to the AW in my mind, and lineage in a way... Or at least if not lineage, necessity for the AW to come into being so the Alliance had fast nimble craft capable of interception since their fleets wouldn't want to engage if possible to avoid it.
Yeah I can talk about this stuff all night.
And upon watching, YES, those appear to be prototype A-Wings, which I believe were called Spearheads or Arrowheads, I forget. It's in the ICS for Yavin Base... And they're using the McConcept Art for the early A-Wing too! Or so it seems anyway. I love it! Another thing I've had on my custom "to-do list" for a long, long time. One can only hope they crank out some of that stuff.
I love that Corellian ship design for Phoenix Squad too (assuming that's part of it). A Corellian variant of a CR90? Or a whole other designation? Is that where they launch attacks from? There was a CR-type vessel in Mysteries of the Sith that had hangar bars aboard instead of traditional cargo holds and carried a squad of X-Wings. I love that stuff.
