Steel's Ship (UE-44)

John Henry Irons utilized a ship during his vendetta against Superman as Captain Luthor, also known as The Stranger.

New World
Luring Superman to outer space, he attacked the ship and damaged its ballistic shields, leaving John vulnerable to attacks. He was then brought to Earth-Prime in a wormhole after firing a Red Solar Rocket at Superman.

Search for Kryptonite
After defeating Superman with his final shard of Kryptonite, John Henry Irons returned to his ship and was asked by his A.I. if he needs to search for more.

Later, he flew the ship to Moldova in search for Kryptonite and realized that it was gone before his search. This flight and attack later caught the attention of the D.O.D.. They were able to build a device to track the ship when it goes airborne afterwards.

In Mongolia, Irons flew the ship to the location and fought Superman. As a method of distraction, Irons placed explosives on the ship and sent it to nearby cities. Superman was forced to stop the bombs and tossed the ship away from the atmosphere of Earth, preventing a devastating explosion from happening.
