Malachowski class

The Malachowski class was a type of Federation vessel, a starship class in Starfleet service in the 23rd century. In the mirror universe, this ship class served Imperial Starfleet. 

Technical data
The Malachowski-class sported a compact hull design. Instead of a secondary hull, the saucer section expanded into a wedge at the rear. A pair of nacelle pylons was attached on the rear ventral hull, behind the layers of decks extending from the ventral center of the saucer. Hanging below the sacuer, and at the front of the ventral decks, was the deflector dish. The lowermost point of the saucer section was the sensor dome. Impulse engines marked the rear of the hull. The warp nacelles on the pylons were long and rectangular.

The basic color was two-toned metallic gray. The ship's registry sat atop a half circle of darker metallic paint. The same paint formed a triangle between the half-circle and the bridge lights. Two trapezoid blocks were on the extended aft section of the saucer. These were reminiscent of the. Overall, the ship's design echoed elements of the Miranda- and es.

Two ships of the class, the USS Clarke (NCC-1661) and the USS Sioux (NCC-1621), particiapted in the Battle of the Binary Stars on May 11th, 2256. The Clarke was lost early in the battle with the Klingons. 

Weeks after the Battle at the Binary Stars between Starfleet and a Klingon fleet that heralded the Federation-Klingon War of 2256-2257, the Malachowski was one of the ships of its class that served as Starfleet Academy training cruise ship for the class of 2256 under the auspices of Captain Anton Shaefer.

Six months later, a picture of the Clarke adorned a mess hall wall of the USS Discovery (NCC-1031).
