10 Times Star Trek Didn't Think It Through
5. Kronos One At The Fleet Museum
The official explanation for Kronos One's presence at Starfleet's Fleet Museum is that it was 'on loan' from the Klingon Empire. This feels a bit tongue-in-cheek, and we're on board with that. But that's really think about this.
Kronos One played a pivotal role in the Federation-Klingon peace talks, so its presence for posterity makes sense. It is also not the only foreign vessel on display - the HMS Bounty and a Romulan-Bird-Of-Prey also adorn these space halls. The Bounty was stolen by Admiral Kirk, whereas there is no Romulan Empire left to demand the return of the Bird-Of-Prey - those we can more-or-less understand.
Kronos One was the Klingon flagship. Allowing for Klingons not being particularly sentimental, it was also the site of the assassination of their Chancellor. Putting it on display feels a bit morbid. Retiring it from service makes more sense but loaning it out to Starfleet - for what purpose?
It was wonderful to see the ship on display, but it doesn't make a lot of sense for it to be there. Still, it was great to see the refit NX-01 in the same shot!
