Why Russia and China Fear America's Ohio-Class Submarines

They might be old, but they could wipe out an entire country in less than an hour.

Nine years after the atomic bombings of Hiroshima and Nagasaki, Ishirō Honda’s Godzilla depicted a monster awakened from the depths of the ocean to wreak havoc on Japanese cities. A giant fire-breathing reptile, however, was less horrifying than what was to come. In less than a decade’s time, there would be dozens of real undersea beasts capable of destroying multiple cities at a time. I’m referring, of course, to ballistic-missile submarines, or “boomers” in U.S. Navy parlance.

The most deadly of the real-life kaiju prowling the oceans today are the fourteen Ohio-class ballistic-missile submarines, which carry upwards of half of the United States’ nuclear arsenal onboard.

If you do the math, the Ohio-class boats may be the most destructive weapon system created by humankind. Each of the 170-meter-long vessels can carry twenty-four Trident II submarine-launched ballistic missiles (SLBMs) which can be fired from underwater to strike at targets more than seven thousand miles away depending on the load.

As a Trident II reenters the atmosphere at speeds of up to Mach 24, it splits into up to eight independent reentry vehicles, each with a 100- or 475-kiloton nuclear warhead. In short, a full salvo from an Ohio-class submarine—which can be launched in less than one minute—could unleash up to 192 nuclear warheads to wipe twenty-four cities off the map. This is a nightmarish weapon of the apocalypse.

The closest competitor to the Ohio-class submarine is the Russia’s sole remaining Typhoon-class submarine, a larger vessel with twenty ballistic-missile launch tubes. However, China, Russia, India, England and France all operate multiple ballistic-missile submarines with varying missile armaments—and even a few such submarines would suffice to annihilate the major cities in a developed nation.

What possible excuse is there for such monstrous, nation-destroying weaponry?
