"Comrades, 23 years they’ve hidden away from us, they ignored our peace offering, they shot down many of our pilot, sunk many of our ships, killed an uncountable amount of people, somehow victory has always been on their side. But now, thing has changed, we’re currently having an unmeasurable amount of firepower in our hand, why should we have to follow the order from above? To me, this ship isn’t a tool, this ship has a purpose, it is meant to end this war in a quick and elegant way, we will kill people, and they will have to be horrified by the amount of lives we will take, only then, they will let go off their weapons and surrender to us. We will bring justice to our land!!! FOR THE EMPEROR!!!” *cheering in the background “Change course to 345!!!” *audio becomes more and more distorted to the point what’s left is only static.
-Touhou Jet: Broken Border~Gensokyo Invasion (Episode 10)-

The Basilisk is one of the Doomsday projects of the *Imperial Japanese Empire, created for the main purpose of taking over the world by force, but the Empire primarily aims for Gensokyo. After the death of Orochi Squadron (Shinigami's squadron), the Basilisk was surfaced in order to attack Gensokyo. However, the crazy captain had another idea, he knew that Gensokyo was weak without the help of Russia, so he planned to detonate the Doomsday nuclear missile on Moscow, killing millions of civillian and to completely messed up Russia, so Japan could have one less enemy force to deal with. Unfortunate for him, his plan was stopped as he was intercepted by 3 battleships and 3 super submarines, one of the subs is also a half carrier. The Basilisk was completely overpowered by the Russian ships. In a desperate attempt to continue his plan, he fake surrendered. After his crew left the ship, took advantage of the Russians distracted by the leaving crew, the captain launched the Doomsday targeted to Moscow city. But his plan was finally failed as Victor had already launched a Zircon III hypersonic missile beforehand from Gensokyo to destroy the Doomsday, the missile detonated before even reaching the shore. The Basilisk took a RSM-56 from the Typhoon-class right in the middle, split in two and sunk to the bottom of the ocean.

*Imperial Japanese Empire: In the Touhou Jet universe, Japan did not take the 2 nuclear bomb and part of the Axis force was still hiding in the goverment. The Imperial Empire was planning to take over the world by force. Then a peaceful leader, Yamamoto became the president, the Imperial force didn't like him so they used his wife to lure and kidnapped him, then they took him to the far North of Russia and imprisoned him there.

I tried to make a controllable Doomsday nuclear missile like in the story, however, it was completely broken so it isn't in the ship, though there's still a hollow part in the front of the ship. Oh and the ship's main hull doesn't have disable collision on so you should be able to land planes on it, as long as the gears don't have disable collision on.

Basic ship and submarine controls (Throttle, Yaw, VTOL)

Anyway, have fun!
