Re: Why No Romulan Ships?
Speaking of Cloaks, why did the Defiant have a Romulan cloaking device, rather than Klingon?
Not entirely clear, but we know that the Federation agreed to provide the Romulans with intelligence reports on the Dominion in exchange for using the device. It may be that the Romulans reached out to Starfleet first wanting information, and Starfleet asked for the cloak in return.
