The Ursini spaceships are large vessels, simmilar to appearance (from an birds eye view) to an elongated hexagon. The ships are colored gray with wide red lines on the edges of each of its surfaces. Its engines are located on the rear of the ship, and consist of 3 Sublight engines. It is possible that the Ursini haven't yet discovered FTL or a hyperdrive system and relie on Stasis pods to keep the crew alive for longer travel. The ships' form is defined by two large wings.(SGU: "The Greater Good")
The ships are equipped by some sort of weapons system, as they were also used against the Berzerker drones. Little is known about the ships' shielding technology, only that it is ineffective against the Berzerker drones.(SGU: "Resurgence")
The Destiny expedition encountered a damaged Ursini spaceship floating in space in an unknown galaxy. The Derelict ship appeared to be heavily damaged as the result of the battle with an unknown force.
After inspecting the ship with a Kino, the expedition sent Colonel Everett Young and Dr. Nicholas Rush to investigate it. They used the Ancient space suits to enter through a hull breach into the ship. Even though the ship's bridge was destroyed, Rush managed to locate a control console, and use it to activate the ship's life support. While doing so he unintentionally activated the ship's sublight drive causing it to drift away from the Destiny.
When the Destiny manages to catch up with the ship, they attempted to dock with it. But due to the pilot's error Destiny collided with the ship. Although the Destiny remained undamaged, due to its force shields, the ship started to wobble. (SGU: "The Greater Good")
Later, the expedition came across the wreckage of 5 Ursini space ships, which were apparently destroyed in a battle with the drones. Unknown at first, a number of attack drones were laying dormant in the debris field and started attacking Destiny, which was then forced to leave the battlefield. (SGU: "Resurgence")
