The ancient Kryptonian Scout Ship 0344 is the base of operations of Kal-El. It was originally commissioned for Kryptonians of the Kryptonian Explorer Guild to travel the stars and scout out planets during their time of expansion. It's former captain, Kara Zor-El, abandoned the ship after arriving on Earth, where it remained for thousands of years before its discovery and repossession by Clark Kent.


After capturing the murderer Dev-Em, Kara Zor-El was assigned as the vessel's designated commander for the scout ship. Soon after they left disembarked from Krypton on their scouting mission, Kara's crew placed themselves into a 10-year stasis. While in stasis, stowaway Dev-Em murdered all crew save for Kara. Ten years later, Kara awoke, coming across Dev-Em, who had diverted the ship's course to the Milky Way system.

During the ensuing confrontation, the two discovered they possessed newfound powers due to yellow sun radiation, eventually destroying integral parts of the ship as they fought. Because of this, they were forced to crash land on a Pre-Historic era Earth. Afterwards, following the death of Dev-Em, Kara abandoned the planet, leaving the derelict scout ship to eventually become entirely covered in ice throughout the ages.[1]

Discovered by NASA

Clark found the ship froze in ice.

After colonial policies were abandoned, it lay dormant on Earth for 18,000 years until it was discovered by Dr. Emil Hamilton, and the United States and Canadian militaries. Whilst traveling in North America, Clark Kent learnt of the craft's existence when he overheard Canadian soldiers talking about it, and so journeyed to the Arctic to investigate. Once the opportunity presented itself he forged a path through the ice with his heat vision and entered the ship.[2]

Flying Fortress

Inside, he placed his command key inside a port, activating an artificial intelligence hologram of his Kryptonian father Jor-El. He revealed Clark's origins to him and passes on advice to his son, and gave Clark a Kryptonian skinsuit telling him to set great examples for humans to follow. Unbeknownst to Clark, his activity on the ship sent a signal that was picked up by General Zod's forces.[2]

After Zod's arrival on Earth, the ship was reprogrammed by General Zod, who erased Jor-El's programming and attempted to use the ship's genesis chamber embryos to rebuild Krypton's population on earth. However, Zod was ultimately stopped by Superman, and the Fortress crashed into the city of Metropolis.[2]

Creating the Kryptonian abomination Doomsday

The wreckage of the Solitude ship sealed off.

Subsequently following General Zod's defeat, the United States government took control of the ship and built a containing facility around it. Lex Luthor manages to gain access to the site after striking a deal with a U.S. Senator with influence. Lex went to the ship and entered using General Zod's fingerprints. He then gained access to the onboard Genesis Chamber and used it to re-create a forbidden Kryptonian abomination creature that he later named Superman's Doomsday using his own blood and the remains of General Zod.[3]

Steppenwolf appears before Lex Luthor

Lex Luthor communicates with Steppenwolf within the Fortress.

After Doomsday battled Superman, Batman and Wonder Woman, seemingly killing the Man of Steel, a SWAT unit infiltrated the Scout Ship, interrupting communication between Lex Luthor and Steppenwolf, as they took Luthor into custody.[3]

After Superman's Death

Months after the death of Superman and during the invasion of Earth by Steppenwolf and his Parademons, the Fortress of Solitude was still kept within the containment facility.[4]
