Browsing: Delta IV

The Delta IV is an expendable launch system that was designed to launch payloads into orbit for the United States Air Force, commercial satellites, and NASA missions. Developed by Boeing and later operated by United Launch Alliance (ULA), a joint venture between Lockheed Martin and Boeing, the Delta IV was first launched in 2002. The rocket comes in multiple configurations, each designed to carry different types of payloads based on their size and orbit requirements. One of the notable versions is the Delta IV Heavy, which is among the world’s most powerful rockets, capable of carrying large payloads to high orbits, including missions to deep space. The Delta IV family of rockets is known for its reliability and has been used for critical missions, including satellite deployments and national security launches. As of the mid-2020s, ULA has been transitioning to the Vulcan Centaur rocket, planning to phase out the Delta IV to make way for this more cost-effective and versatile launch system.
