The Hammer Drones were the result of Justin Hammer enlisting Ivan Vanko to render Iron Man obsolete. Hammer wanted manned suits, but Vanko created remote-controlled drones instead, wishing to use them to attack Tony Stark. Hammer brought the drones to the Stark Expo in the hopes of regaining his contract with the government. Vanko sabotaged Hammer's efforts by activating the drones and making them wreak havok across the site of the Expo. Iron Man and War Machine were eventually able to defeat the drones, as well as Vanko himself.
