During mid-2011, it was postulated that an evolved 'Europeanised' upgrade of the Vega rocket could be developed in the medium-to-long term future. Following the successful first launch, various improvements for the Vega were postulated. The German Aerospace Center (DLR) was reportedly enthusiastic on the prospects of developing a European alternative to the Vega's final, fourth stage; however, it was widely believed that there should be no change to Vega hardware for roughly 10 years in order to consolidate operations and avoid unnecessary costs early on. European Space Agency (ESA) was also keen to take advantage of potential commonalities between the Vega and the proposed Ariane 6 heavy launcher.
