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.
This is referencing the absurd crash from the very end of Formula E's debut race, the 2014 Beijing E-Prix. Nicolas Prost scored pole for Renault at the event and remained in first position until the final lap, at which point Nick Heidfield (who had worked his way up from 8th) made a pass for the lead in his Venturi. Prost practically rammed Heidfield as they were side by side, which sent the Venturi skidding into a sausage curb that launched it into the air, while also damaging his own Renault into immobility - ultimately allowing Lucas di Grassi's third place Audi to slip into the lead and claim FE's maiden victory.
The clip can be seen on YouTube here - everyone walked away unharmed from the incident, but it's still a pretty gnarly crash so be warned. It starts off with the incident itself, and then does a replay from Prost's POV at 1:53.
