Past, present and beyond

Delta rockets have been built and launched since 1960. Delta’s origins go back to the Thor intermediate-range ballistic missile, which was developed in the mid-1950s for the U.S. Air Force. The Thor, a single-stage, liquid-fueled rocket, was modified to become the Delta launch vehicle, which later evolved into the Delta II. Today, the Delta IV blends advanced and proven technology to launch virtually any size medium-to-heavy class payload to space.
