I think Riyo stuck gold with Baobhan Sith. Unlike Liz, Baobhan's a natural enemy of some of the most popular servants like Artoria, Castoria, Mordred and Gareth.
The artist isn't likely to be on Danbooru, so you're better off contacting them through their Twitter. Also I was not expecting the N-word from that link.
The Halford was outfitted with a catapult meant to launch scout planes, but was deemed unfeasible before she was converted into a standard DD.
The WoWS version, which this one is based off, basically asked "but what if it works?". In simple terms, she's a fanfic version of a real ship.
USS Steven, Halford's sister actually launched a plane on an operational mission, while Halford was only on sea trials in this configuration, the concept worked but it wasn't deemed necessary what with the sheer amount of carriers we had on stocks. Honestly I'd rather have seen either one as an event ship and something more silly for this PR slot, the problem is the US simply lacks truly silly blueprint ships, if only world of warships implemented some of the ridiculous US WW1 or interwar designs like the Tillmans or the S-584-166 submersible 8" cruiser.
