I found this incredibly interesting Kantai Collection fanfic the other day, written by someone on the spacebattles/sufficient velocity crowd. It's called 'The Greatest Generation', and it's set in a slightly next-sunday-AD setting where the Abyssal fleets are appearing and terrorizing most of the world, and the shipgirls, correspondingly, are awakening to handle them... except they're under the jurisdiction of the UN, they're spread thinly, and an awful lot of them have... opinions, or even worse lack of understanding, about the actual historical background of WW2.

And then a naval intelligence officer named Yvonne Swanson gets involved to try and find out why the Kanmusu aren't responding to US summons for help, and things get... interesting.

You can check it out at https://www.fanfiction.net/s/11187030/1/Kantai-Collection-The-Greatest-Generation , and tvtropes has links to its in progress threads at http://tvtropes.org/pmwiki/pmwiki.php/Fanfic/TheGreatestGeneration. It's ongoing, though.
