The End of MIRVs for U.S. ICBMs

The United States last week finished removing the last MIRV (multiple independently targetable reentry vehicle) from its Minuteman 3 intercontinental ballistic missiles (ICBMs); these missiles will now each carry a single warhead. The move was the fulfillment of a promise the Obama administration made in its 2010 Nuclear Posture Review, which stated that it would “enhance the stability of the nuclear balance by reducing the incentives for either side to strike first.”  Read More
