 On April 26, 2021, the 30th Space Wing and United Launch Alliance launched a Delta IV heavy rocket from Space Launch Complex 6, Vandenberg Air Force Base, California, with a national security payload. Launch preparations began over a year ago when Team Vandenberg and ULA received the interest of the Delta IV that arrived via the RS rocket ship, a cargo vessel specifically designed to transport components of space launch vehicles. In addition to its mission assurance responsibilities of checking and double-checking the flight worthiness of the launch vehicle, the second Space Launch Squadron led practice sessions with Team Vandenberg and ULA, ensuring that all members were 100% ready for the big day when the Delta IV lifts off. The liquid-entered Delta IV, made of an upper stage with one main booster and two strap-on boosters, is capable of lifting more than 62,000 pounds into low-Earth orbit, or 30,000 pounds into geostationary transfer orbit. Today's lift-off shows Vandenberg is the premier West Coast launch site, and Team Vandenberg continues to provide secure access to space while keeping public safety in the forefront of every mission.
