Chatham Main and Medway Valley Lines - Hidden Destinations

I only stumbled on this last night when creating a scenario for the new Chatham Main and Medway Valley Lines route. Although i'm not really a fan of Star Wars, I did find it mildly amusing.

Having now looked at the route manual and in particular the section for the Class 375 destinations, I can now see that entries are missing for the T, U & V destinations. It turns out they are the following:

T = Death Star via Tattoine

U = USS Enterprise NCC 1701 

V = USS Defiant NX 74205

Despite not being a fan I do recognise the Death Star and Tattoine, along with the USS Enterprise. I'm clueless as to what USS Defaint is though, along with the letters and numbers.
