What was the purpose of the ares V rocket?

The Ares V rocket was designed as part of NASA's Constellation program, intended to support crewed missions to the Moon and eventually Mars. Its primary purpose was to deliver large payloads, including the Orion crew vehicle and lunar landers, into low Earth orbit and beyond. The Ares V was envisioned to enable deep space exploration by providing the necessary lift capacity and reliability for human spaceflight missions. However, the Constellation program was ultimately canceled in 2010, and the Ares V was never built.
