|Owner:||United Federation of Planets|
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.
