Testing intercontinental ballistic missiles (ICBMs) is not uncommon. The United States tested an LGM-30G Minuteman III ICBM off the coast of California as recently as Feb. 25, its second Minuteman III test that month. Though nuclear testing has largely ended (the exception being North Korea) since the Comprehensive Nuclear-Test-Ban Treaty was adopted in 1996, testing of the delivery vehicles for nuclear warheads continues unabated. Testing ensures that nuclear-capable missiles continue to work and have not deteriorated with age. It also broadcasts reliability to potential enemies, conveying a country's still-active capability to launch a nuclear strike. Finally, even though countries such as Russia and the United States are restrained by the New START (Strategic Arms Reduction Treaty) and the Intermediate-Range Nuclear Forces (INF) Treaty , launches help modernize nuclear arsenals. As new missiles and bombs are built, they require tests to see whether they can effectively reach their target.
