According to unconfirmed information, this reactor generates 210 megawatts [MWth], which helps to drive a pump-jet propulsion system with 30 MW. The reactor is corrosion resistant, has significantly reduced life cycle costs, and provides the submarine with energy density. According to the reactor manufacturer, 33 years is the maximum life cycle that a submarine can reach with this reactor if it is not replaced.

The USS Oregon [SSN-793] is armed with 12 long-range, all-weather, jet-powered, subsonic Tomahawk cruise missiles, which are launched from 12 vertical launch systems integrated into the submarine. Additionally, the submarine has 4 21-inch torpedo tubes through which Mk48 torpedoes are fired.

25 knots is the maximum speed of the vessel, which is 115 meters long. It can be submerged to a depth of 244 meters and remain underwater for a maximum of 3 months. The crew consists of 15 officers and 120 sailors.
