In 2370, the Valor and the USS Regal were assigned to escort the antimatter tanker Phoenix to Deep Space 9. Nearing the space station the Valor and the Regal were attacked by Klingon mercenaries in Birds of Prey.
The Valor was badly damaged and one member of its crew was killed by a radiation leak. Miles O'Brien and Julian Bashir beamed aboard to repair the ship and treat its crew. The ship remained disabled and was unable to help DS9 and the Regal fight off a squadron of Cardassian fighters. (DS9 novel: Antimatter)
