World of Warships Supertest: Japanese Supercarrier Sekiryu
5 min readHistorical Background
Sekiryu is a fictional follow-on design to Hakuryu. In essence, it is an upscaled Hakuryu with thicker armor protection and a much stronger secondary and anti-air armament. Hakuryu herself is a mix of the G14 and G15 designs from the Imperial Japanese Navy. Said designs were meant to be improved versions of the Taiho.
Sekiryu herself is going in a fairly different direction from the United States and Eagle. Unlike the others, she keeps all the standard squadrons of Hakuryu and they don’t get JATO rockets for the early deployment speed increase. For the tactical squadrons, the ship gets Attack Aircraft and Torpedo Bombers.
Ship’s preview
For the classic reminder, this is a ship in testing, anything can change so don’t look at her like she would already be released.

Personal Opinion
Welp.
Sekiryu looks particularly spicy and it’s putting it lightly. The ship has identical standard squadrons as Hakuryu in every way but on top of that, she gets tactical squadrons as additional striking power. By design alone, she is fascinating as, unlike United States or Eagle, she doesn’t lose any of her standard squadrons, making it a lot more comfortable for rotations and reserves management. This also means that with her standard squadrons alone, we are already looking at a powerful carrier as Hakuryu herself is one of the top dogs at tier X.
As for the tactical squadron, one is a squadron of attack aircraft firing the same rockets as the standard counterpart but with more rockets and far shorter firing delay. Considering that Hakuryu’s rockets were already a great weapon against most cruisers, these jets are going to be nasty. Depending on their maneuverability, they might also end up being useful against destroyers.
The torpedo bombers are also going to be a force to fear (unless they somehow get horrible spread) as it’s the damage of 2 attack runs from standard torpedo bombers packed into a single strike for a potential damage of around 30 000.
Needless to say that I absolutely can’t wait to try this thing on the live server.

Not sure why a ground-based high-altitude interceptor got shifted to a carrier-based attack craft (both J5N and J7W3).
Same kinda goes for the land-based recon airplane (R2Y2).
Conveniently ignoring the part where IJN jets were… quite experimental at the end of the war.
Makes me wonder if the flight deck is long enough for take-off; either with or without the catapults as aid.
