United Launch Alliance

ULA was formed by the union of Boeing and Lockheed Martin in 2005, using the Delta IV Heavy launcher to get large payloads into space. But the price tag for that rocket is high, several times more than SpaceX’s Falcon Heavy platform. That’s why ULA is working on a more powerful and semi-reusable launcher known as the Vulcan. The recyclable portion of the Vulcan system will be the engines.
