The DV-20 Vasilisa is a multirole fighter by the Desya Vladimir Fighter factory.
This particular version of the Vasilisa is a heavily modified version to combat the Kawaseki's Cicada.

It features large wings, 2 rear wings that act both as the rudders and elevators, 2 cameras, one facing to the rear behind the cockpit, and one on the bottom facing forward, to help identify ground targets and landing. The original version of the Vasilisa had smaller wings, and no cameras, and wasn't even carrier capable.

During the Silver Sea Conflict in 1965, right at the end of the Age of Industry, the Tsardom invaded the eastern islands, hearing rumours of precious resources that are untapped by the de-jure owners of those islands, the Kawaseki Shogunate. Believing in their superior industustrial capacity, and sheer numbers, the Tsardom planned a full invasion of Kawasakura, the home islands of the Kawaseki Shogunate. However, the plan was postponed, and ultimately trashed when they learned just how fierce Kawaseki soldiers are, as well as the deceptive nature of Kawaseki's Main fighter, the Cicada.
It also didn't help that the Tsardom's navy was vastly inexperienced, as most of the wars the Tsardom fought were land wars. All the navy really did was park their ships in front of the enemies harbours and twiddle their thumbs. A stark contrast to the greatly feared Kawaseki navy, which during the Kawa-Valeran war in 1897, sunk the Grand Holy Valeran Fleet of 1200 Ironclad ships, with only 200 old Wooden battleships, at the command of Admiral Hideo Tomosuka. As well as completely maintain "Sea safety" for hundreds of years from the horrors that lurk in the deep, such as leviathans, Bull-faced Mouthfins, and other monsters over 100 meters long.
The Silver Sea conflict ended in armistice, both sides being thoroughly beaten at different aspects. Kawaseki yielded around 130 of the 2232 islands under their control, while the Tsardom was to disarm a third of its military assets for a period of 30 years.

An ace pilot with a record of 30 kills a sortie, by the name of Boris Fedeaushka, was personally commended by the Shogun of Kawaseki, Mamoru Kawaseki, for his noble endeavour to spare every Kawaseki who were in the process of retreating, even going as far as to commit friendly fire if anyone were to give chase.
