// Союз нерушимый республик свободных
// Сплотила навеки Великая Русь.
// Да здравствует созданный волей народов
// Единый, могучий Советский Союз!
// Славься, Отечество наше свободное,
// Дружбы народов надёжный оплот!
// Знамя советское, знамя народное
// Пусть от победы к победе ведёт!
// Сквозь грозы сияло нам солнце свободы,
// И Ленин великий нам путь озарил:
// вырастил Сталин — на верность народу,
// труд и на подвиги нас вдохновил!
// Славься, Отечество наше свободное,
// Счастья народов надёжный оплот!
// Знамя советское, знамя народное
// Пусть от победы к победе ведёт!
// Мы армию нашу растили в сраженьях.
// Захватчиков подлых с дороги сметём!
// Мы в битвах решаем судьбу поколений,
// Мы к славе Отчизну свою поведём!
// Славься, Отечество наше свободное,
// Славы народов надёжный оплот!
//Знамя советское, знамя народное
//Пусть от победы к победе ведёт!
