The Dome, in Brussels, attempted to recreate the Super Soldier serum that created Captain America, much like the Americans, with little luck. They opted to go the Bio-Mechanical route instead and created a Harness and Power-Belt that provided the wearer the with the abilities of flight, Super-Strength and limited Invulnerability. The test subject, Thorlief Golmen, a psychiatric nurse, was fitted with the suit. However during the testing process he started ranting about how he now believed he was actually the God of Thunder, Thor. He was institutionalized as the delusions worsened.
The team working on the Harness made several modifications to the suit using inspiration from Thorlief's rantings, adding weather control and teleportation to the Harness and Belt. The only problem was how to include the power source. It was Thor himself who suggested nestling it inside a Hammer, which fit nicely into the Norse Iconography the suit now had. When Loki was freed from his Asgardian prison cell by an aged Helmutt. He used his trickery and illusions to place himself on the team and took on the alias of Gunnar Golmen, Thorlief's brother.
Eventually Thor broke free from the facility and began his life as a super-powered humanitarian. Loki managed to convince both the European Defense Initiative and S.H.I.E.L.D. that Thor was insane and a powerful threat. The Ultimates were then charged with finding and apprehending him.  In reality, Thor really was a god reborn in human form; powerless. The Ultimates managed to find and arrest Thor, stripping him of the suit. Thor would later reclaim his actual powers, ending his need for the suit.
The Russian government somehow got their hands on the suit and used it to aid, along with the Chinese government, in their invasion of America. The technology was fitted to one of their soldiers and was given the code-name Perun, the Slavic God of Thunder, to fit the theme of the powers the suit provided. The shape of the hammer was altered, but retained all of it's abilities. He was also given a Sickle to match the Hammer to add to his Soviet symbolism. The Russian and Chinese governments created a team of super-powered individuals to lead the invasion, called the Liberators, and Perun was placed on this team.
Two years later, Perun was working for S.H.I.E.L.D. as a Black Ops agent on the Avengers. During an attack on the Triskelion by a Vampire Army, Perun was killed by a Vampire Banner. The hardware has yet to be assigned to a new host.
Tony Stark fully upgraded the hardware to make it better than it's previous versions. When Asgard was destroyed by the Children of Tomorrow, Stark offered the hardware to Thor, who has once again been transformed into a mortal man.. This version of Mjolnir is fully compatible will "all Iron Man power sources".
