The war between Concordia and the United Nations, led by the Russian Directory, became one of the largest astropolitical upheavals of the third millennium. Armored armadas converged in space. Hundreds of combat starships - battleships, aircraft carriers, frigates, monitors - rained down streams of steel and fire on each other. Concordian landings, taking advantage of the factor of operational surprise, captured the key planets of the borderland - Grozny, Clara, Lucia, Machaon. In these terrible days, when the fate of the Fatherland hung in the balance, combat weathervane pilots stood up to defend Russia. Reflecting massive enemy raids, attacking enemy starships through murderous anti-aircraft fire, they buried the Concordians' hopes for a quick victory. And then came the turn of the general battle - the Battle of the Eight Hundred and First Parsec... Lieutenant Andrei Rumyantsev - in the active fleet. What awaits him and the pilots of the 19th separate air wing in the fateful battles of 2622?
