The Mariinsky Theatre is a historic theatre of Opera and Ballet in St Petersburg. Opened in 1860, the Mariinsky Theatre (renamed the Kirov Theatre during the Soviet period) is one off the most famous theatres in the world, with many famous composers, ballets/ dancers and operas/singers premiering here. Including the works of Tchaikovsky, the ballets Swan Lake and the Nutcracker and many of the world’s most important dancers, for example Anna Pavlova, Vaslav Nijinsky, Galina Ulanova, Rudolf Nureyev, Natalia Makarova and many more. The theatre is currently home to the Mariinsky Ballet, the Mariinsky Opera, and the Mariinsky Orchestra. A second stage was recently completed to add to the original theatre and the 2007 Mariinsky Theatre Concert Hall.
Designed in 1957 at the Kirov factory in Leningrad, Object 279 had a unique elliptical design to withstand overpressure and blast waves generated by nuclear detonation without overturning. Armor was extremely thick for the time, with 269mm in front, 182mm on the sides, and 319mm in the turret. A 130mm gun was the main armament. The four crawler undercarriage was unique, allowing the tank a greater ability to breach vertical obstacles and spreading ground pressure out so that deployment in deep snow and swamps was possible.
Testing of the tank began in 1959, but the high cost soon rules out serial production of the model. One tank was built, and is on display at the Kubinka Tank Museum in Russia.
