One of the Defiant-class ships bears the registry NS-47205, denoting it as the USS Defiant, the hero ship from Star Trek: Deep Space Nine (1993). Given the timeline, this would be the second Defiant of its class, which was originally designated the USS Sao Paulo.
The Starfleet fleet seen here consists entirely of Sovereign-class, Defiant-class, Akira-class, and, oddly, Centaur-type ships, plus the Protostar and the USS Dauntless. While the other ship classes appeared prominently in the Star Trek franchise, the Centaur-type only appeared briefly in the later seasons of Star Trek: Deep Space Nine (1993). The Centaur was a "kitbash" ship, built by the special effects team out of parts of commercially available Excelsior and Miranda-class model kits. It is so obscure that it was never given an official class designation, being referred to as a Centaur-type based on the name of the first example to appear on screen, the USS Centaur.
Around 6:00, when Janeway mentions a Voyager event, an excerpt of the Voyager main theme is heard.
The female Bridge officer (who is voiced by Dee Bradley Baker) that gets Janeway out of the brig is a female Brenari.
