Republic of Avista

The Republic of Avista is a country that resides on floating metal landmasses. Birds live there, and they are technologically advanced that they developed jet fighters during World War 2, and sent the first living Earthling to the moon in 1949, sending one eagle and two peregrine falcons to the Moon. The Republic of Avista is maintaining strong ties with the United States of America and Russia, since they never have been at war with a human and animal country, ever.
== History ==
At April 9, 1870, bird scientists managed to invent Dove Levitators, named after Christopher F.A Dove which can basically lift anything at any altitude. The bird scientists decided to keep it a secret from humans. Being (secretly) the first animals to become self aware at 1811, they did not want humans to learn about this feat.
They started making a flying artificial island, made out of steel grass and soil, over the area which is now called Point Nemo, or Nemo Sea building it behind the human eye. The construction took years, and they managed to finish 10 floating Columbia-sized islands at 1911. They afforded the project by trading in a secret stockpile of diamonds from trusted humans, to get equipment, etc. In 1913, millions of birds moved there, making homes immediately.
A year later, January 1914, 1 billion birds have moved in to Avista. Months later, unfortunately, fear rose in Avista when the humans started fighting in World War One. The Avistan government did not care for now since their location was still unknown to the humans, Well, until December 1918, when an asteroid with magical properties made almost all animals (except animals humans eat, insects and bacteria) self aware.
Avista decided to reveal themselves to the public, shocking every human (and animals) on earth.
It's been years since peace until World War Two. This time fought by dogs, serving in the human countries, which are divided in two groups. The Allies and the Axis. This time the government took action. This time a solution has arised by one of the top scientists in Avista City University, inventing jet-powered aircraft and targeting systems.
They managed to make the first secret jet-powered fighter armed with missiles, a very advanced plane in it's time. The plane was armed with 4 guided missiles. It was then called the AV-1 Peregrine.
They also kept their state-of-the art aircraft a secret.
They then survived many wars by staying neutral; became richer through the ages, doubled the population, till today, 2021, they are the global superpower, richer than the United States and Brazil combined.
== Military ==
The Avistan Air Army and Air Force is undoubtedly the most strongest and advanced military aircraft in the world. They operate fighter jets and helicopters and have 3.9 million bird soldiers in service, and 1 million in reserve. They have a few warships, they also operate 15 Zumwalt-class destroyers in service. Their helicopters are basically still a prototype in the United States. The Avistans operate AV-4000 Petrel and RAH-66 Comanche attack helicopters, B-2 Spirit bombers, and they have various fighter jets, the AYF-23 Black Sparrow, the Avistan variant of the YF-23 Black Widow, the FA-99 Seagull, the Avistan variant of the still prototype F/A-XX in the United States, they also operate the MiG-41.
Wait, they are operating prototypes? Why don't the other countries follow suit. It's not that simple. Avista and the United Nations signed the Bird City Purchase Treaty, which is made that Avista can only buy, not sell, advanced technology, so humans and animals won't get too ahead of themselves.
Their soldiers are made up of birds, mostly flying birds, and they wear sky-blue uniforms to be disguised in the sky. They are usually armed by TR-7 assault rifles, which can fire faster than an AK-47. 
Their special forces are basically called the Avistan Ravenguard, because they are made up mostly by ravens. They may be smaller than dog soldiers,soldiers of the human countries, but they are much more dangerous.
