Not heard anything about the USN jackets. I know Ken has made significant changes to at least some of the A2 patterns (though the photos haven't, to my knowledge, been updated on the website to reflect this), so it's entirely possible he's done the same with the USNs. I think they're still pitched online as generics of the design as distinct from specific contract repros (again, no idea whether the site is up to date on that), but they may have changed 'em up a bit so they more reflect a particular contract. [huh]
A couple have been updated. Particularly like the aniline steer:
