Veteran rock act AC/DC is to headline this year's edition of U.K. metal/rock festival Download.

Other acts confirmed for the three-day festival, which takes place at the Donington Park motor racing circuit June 11-13, include Them Crooked Vultures, Stone Temple Pilots, Deftones, Wolfmother, Megadeth, Bullet For My Valentine and Motorhead and Stone Temple Pilots, who will be making its first U.K. live performance since reforming in 2008.

Download festival was launched in 2003 as a replacement for the long-running Monsters of Rock festival, which was established in 1980 and ran at the site until 1996.

AC/DC's appearance at this year's event will mark the fourth time that the veteran Anglo-Australian rock act have played the historic site, although the first time in its current Download guise. The event is produced and promoted by Live Nation.

It has also been confirmed that the festival's daily capacity will be increased this year from last year's 85,000 sell-out. In a statement, it was claimed that this year, Download would be the U.K.'s second-biggest festival (behind Glastonbury), although a spokesperson says the final capacity has not yet been confirmed.

Download festival promoter Andy Copping said in a statement: "Download 2010 will be one for the history books. It will see the return of the world's greatest rock band to the most legendary and spiritual home of rock."

Praising the Donington site for "its continuing flexibility", Live Nation COO John Probyn added in a statement: "We are thrilled that our 30-year association with the site will be marked not only with a superb line-up, but also by the expansion of Download 2010 to accommodate more festival-goers than ever."

Tickets for Download 2010 go on sale Jan. 29 through www.downloadfestival.co.uk.
