No, and the devs have never once said they’re even considering adding A-150 at the time of writing. OP just got fooled by Gaijin’s “passed to developers” chaff and decided to post a lie on the forum, then didn’t correct it.
As it stands, all we have to go on is precedent. Every single ship that has been added to the game since naval came out had at least part of the hull built. A-150 did not. The only reason it was accepted as a suggestion is because those guidelines are different and allow for ships that had any unique part of it built. In this case, it was the guns.
