In late 2374, Benjamin Sisko, Miles O'Brien and Julian Bashir used the Chaffee to enter the atmosphere of a Class L planet to rescue Lisa Cusak. The use of the pod was preferred because its power systems did not utilize antimatter, and made it possible for the pod to survive travel through the exotic energy field surrounding the planet. (DS9: "The Sound of Her Voice")
The Chaffee was designated as Defiant shuttlecraft 1. 
According to Deep Space Nine series of novels, the shuttle Chaffee could have survived the destruction of the Defiant at the Second Battle of Chin'toka in 2375, as it was mentioned being assigned to the second USS Defiant also.
