Are the variants mentioned "officially announced"?

The variants mentioned in the post exist in our fiction, and we hope to build out all of them down the line. We likely will not have a 'Starliner variant' launch, but instead will premiere them as they are needed for the wider universe. We're especially excited about the military variants, which were part of the inspiration for building a durable ship chassis. These variants are still under construction, and we hope as the ship continues to evolve that we can offer more and more variants and options.
