Vice President Joe Biden will be the guest speaker at the Air Force Academy graduation in May.
Biden's appearance was announced Monday. He also addressed cadets at the 2009 graduation.
Graduation is May 28 at Falcon Stadium on the academy campus north of Colorado Springs.
About 1,000 cadets are expected to get their diplomas and be commissioned as second lieutenants.
Air Force Secretary Michael B. Donley spoke to cadets last year. President Barack Obama was the 2012 speaker.
