Kriosian battle cruiser

From Memory Alpha, the free Star Trek reference

The Kriosian battle cruiser was a type of warship used by the Kriosians during the mid-22nd century. Along with protecting Krios space, the Kriosian battle cruiser was also assigned the duty of protecting the First Monarch and the Royal family, which was known across hundreds of worlds.

In September, 2152, a Kriosian battle cruiser rendezvoused with Enterprise NX-01 to receive and transport First Monarch Kaitaama. (ENT: "Precious Cargo")

The Kriosian battle cruiser is a re-use of the CGI for the Akritirian patrol ship, and even still has the emblem of the Akritirians.
