The Soviet Union decided the best way to show up the West was to build the biggest version of any given object. The following are just seven of the largest examples.

1. A Palace for the People

In 1931, Joseph Stalin ordered that the largest Orthodox Christian cathedral in the world— 335 feet high, the product of 44 years of back-breaking labor by Russian peasants—be dynamited so he could build an enormous "Palace of the People," to celebrate the Communist Party. Stalin wished to replace the church with a new structure taller than the Empire State Building, and capped with a gilded statue of Lenin taller than the Statue of Liberty. But the "Man of Steel's" mad scheme never came to fruition. Although the first phase was completed (the dynamiting was the easy bit), the construction never took place as necessary resources were diverted to fighting World War II. After Stalin died, his successor—Nikita Khrushchev—ordered a large swimming pool built where the cathedral had stood. Old women who remembered the original cathedral could be seen standing at the edge of the swimming pool, praying to forgotten icons. Recently Yury Luzhkov, Moscow's autocratic mayor, tried to make up for Stalin's mess by ordering the construction of a tacky reproduction of the original cathedral using precast concrete.

2. Avant-garde Design for a Funkier Parliament

Designed by Vladimir Tatlin (1885"“1953) in 1920, the Monument to the Third International was a gigantic spiraling iron structure intended to house the new Soviet government. Taller than the Eiffel Tower (and the yet-to-be constructed Empire State Building) at more than 1,300 feet, this curving, funnel-shaped structure was meant to encase three successively smaller assembly areas rotating on industrial bearings at different speeds, faster or slower according to their importance. Rotating once a year in the lowest level was a giant cube for delegates attending the Communist International from all over the world. A smaller pyramid, rotating once a month above it, would house the Communist Party's executives. The third level—a sphere rotating once daily—would house communications technology to spread propaganda, including a telegraph office, radio station, and movie screen. Unfortunately the giant structure would have required more iron than the entire Soviet Union produced in a year, and was never built. [Photo courtesy of Wikipedia.]

3. Magnitogorsk

Whether it was for guns, tanks, ships, railroads, or bridges, Stalin, whose name means "Man of Steel," knew he needed one thing above all else for his 1920s Soviet Union: steel. He also knew that to the east, in the southern Ural Mountains, there was a unique geologic oddity named Magnitka—an entire mountain of pure iron ore, the key ingredient for steel. In 1929, Stalin decreed that a city, "Magnitogorsk" (see what he did there?), be built from scratch around said mountain to mine the ore and turn it into steel. So began one of the largest construction projects ever undertaken. With expertise provided by Communist sympathizers from the West, a ready-made city for 450,000 inhabitants was constructed in about five years. Of course, Stalin saved on labor costs by having the heavy lifting done by political prisoners. In fact, 30,000 people died in the effort. Steel production began in 1934, but shortly after World War II the city's economy collapsed. [Photo courtesy of Katardat.org.]

4. The Baltic"“White Sea Canal

Ever the optimist, this time Stalin wanted to connect the Baltic Sea, with its key port of Leningrad, to the White Sea's port of Archangelsk. The idea was that he could move the Soviet navy fleets back and forth. So Stalin had more political prisoners sent to work on the canal—there was a seemingly endless supply from the gulags—and after a few brutal years it was completed in 1933. Disease, poor nutrition, and brutal conditions took a huge toll, though, with as many as 250,000 of the slave laborers dead by the end of it. The icing on the cake? The canal was completely useless when finished. For most of its length it was too shallow to admit anything larger than a small barge. Later a book of propaganda detailing the biographies of "heroic" workers and engineers, intended for distribution in capitalist countries, had to be recalled because in the downtime Stalin had ordered all the main characters shot.

5. The World's Largest Hydrofoil

The world's largest hydrofoil wasn't really a hydrofoil at all. In fact, it was one of a series of unique machines called "ground effect" vehicles built by the Soviet Union beginning in the 1960s. The Soviets had a monopoly on this fascinating technology, relying on a little-known principle of physics—the "ground effect"—in which a dense cushion of air hugging the ground can provide more lift to a vehicle than air at higher altitudes. Hovering about 3"“12 feet above the ground, these vehicles resemble Luke Skywalker's levitating craft from Star Wars, and are far more fuel-efficient than airplanes, helicopters, hydrofoils, or cars. And at 58 feet, the largest of these, the "Caspian Sea Monster" was given its distinctive name after CIA analysts saw it at the Caspian port of Baku in photos taken by spy satellites. The craft traveled at speeds of up to 240 mph, had a swiveling nose cone for cargo loading, and could carry up to as many as 150 passengers. [Photo courtesy of Wikipedia.]

6. The World's Largest Hydrogen Bomb

Truth is always stranger than fiction, so it's no wonder that Stanley Kubrick's absurd comedy Dr. Strangelove is actually premised on fact. The strange truth here was that Nikita Khrushchev and company had actually been plotting to build a "doomsday" device. The plan called for a large cargo ship anchored off the Soviet Union's east coast to be loaded with hundreds of hydrogen bombs. If at any point the radiation detectors aboard the ship measured a certain amount of atmospheric radiation, indicating that the Soviet Union had been attacked, the bombs would detonate. Soviet scientists persuaded Khrushchev to drop this mad scheme. He did, however, order the construction of the world's largest nuclear bomb in 1961, the so-called "Czar Bomba" ("King of Bombs"), which weighed in at about 100 megatons—equivalent to 100 million tons of TNT. The largest nuclear test involved a smaller version of "Czar Bomba" that measured somewhere between 50 and 57 megatons—the Soviets weren't sure themselves.

7. World's Largest Icebreaker, the Yamal

Confronted with the world's largest piece of ice—the Arctic Ocean—the Soviets had no intention of letting nature stand in their way. So, they came up with a simple solution: the world's largest icebreakers. The first included the Lenin and Arktika class of nuclear-powered icebreakers, introduced in 1959 and 1975, respectively. The Arktika ice-breakers had not one but two nuclear reactors, powering 75,000-horsepower engines. None compare with the newest vessel, however—the Yamal—launched in 1993. Also powered by two nuclear reactors, it measures in at 490 feet long, displacing 23,000 tons of water, with a crew of 150 and an armored steel hull 4.8 centimeters thick. Recently reoutfitted for tourist operations, it has 50 luxury cabins, a library, lounge, theater, bar, volleyball court, gymnasium, heated indoor swimming pool, and saunas. A helicopter is stationed on the ship to conduct reconnaissance of ice formations. [Photo courtesy of ikzm-d.de.]
