Kelvas repair facility

From Memory Alpha, the free Star Trek reference.

The Kelvas repair facility was a Cardassian space station located in the Kelvas system in the 24th century.

In 2375, Breen engineers were installing energy dampening weapons aboard Jem'Hadar attack ships at the repair facility. A five-person team from the Cardassian Rebellion was able to infiltrate the station and steal one of the retrofitted attack ships, bringing the weapon back to the Federation for study.
