On its own.
Meanwhile, the New START treaty which came into effect in 2011 imposes additional limits on the number of deployed nuclear weapons. The current plan is to keep twelve Ohio-class subs active at time with twenty Trident IIs each, while two more boomers remain in overhaul, keeping a total of 240 missiles active at a time with 1,090 warheads between them. Don’t worry, restless hawks: that’s still enough to destroy the world several times over!
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.
