The Steamrunner class was my number one desire for an addition, Crytic just showed it really cares about getting all the canon ships in, which one would you like to see next?

My vote goes to the Springfield class, it's the best thing they ever did with the Galaxy style imo.

Oh, and the Ambassador doesn't count, we already have a guarantee that it's coming.

Andorian Battle cruiser....

Dauntless

In an alternate timeline, the Federation appeared to have adopted this design by the 26th century, with at least one Dauntless-class starship participating in the pivotal Battle of Procyon V. (ENT: "Azati Prime")

Kumari aka Andorian battlecruiser.

The Andorian ship is confirmed as well.

I'd have to say New Orleans for starfleet , K'vort for KDF

Dauntless class

was not made by starfleet and ive not seen it in any thing other then the one EP from Voy

and to "Although created by alien technology, the ship was modified to resemble Federation starships on the interior and exterior by the means of particle synthesis."

You want to re-watch the Enterprise episode "Azati Prime".

When Archer is taken to the future, the battle of Procyon V, there are at least 2 shots of Federation Dauntless classes outside the window.

Reused models made to just fill the scene? Yes! But that still makes it a canon federation ship

It's also an absurd future where the Federation builds (built? while have built? will be building?) ships that are armed with Phase Cannons and look like Deep Space 9 on the inside.

It's also an impossible future since they destroyed the Spheres at the end of Enterprise's third season.
And it already took them 1000 years to create the expanse which had a diameter of 2,000 light years while the expanse in the in th 26th century had a diameter of 50,000 light years.

Assuming the rate of growth of the expanse increases over time, it might have been possible for it to grow to that size if the process had not been interrupted and totally reversed by Enterprise.
But it's one of those futures that can't come to pass, given later developments and because obviously the technology of that Federation developed into totally different directions from the one in our timeline at a very early stage, probably before TOS.
