America updates its nuclear bombs


A $100 billion dollar project to upgrade the United States’ largely outdated nuclear arsenal is underway.

Since the Cold War, the U.S.’s stockpile of weapons built during the arms race with Russia stands at about 1,500 nuclear bombs and warheads today. Although the Obama administration has promised not to build more nuclear weapons, major efforts are being made at labs around the country to improve the accuracy and security of existing bombs, like the B-61.

A lightweight two-stage thermonuclear weapon, the B-61 was first developed in the 1960s and relied on an out-of-date parachute guidance system and obsolete analog components. An $8 billion plan to upgrade the B-61 — the U.S.’s most expensive bomb project ever — will improve its technology, making it a more accurate and reliable weapon with less nuclear fallout and fewer casualties.

“If we have a weapon that is lower-yield and greater accuracy, and our adversaries know that, it’s my own belief that that weapon then is a more effective deterrent,” said Donald Cook, deputy administrator at the National Nuclear Security Administration.

Nuclear engineers at Los Alamos National Laboratory in New Mexico have developed a more easily controllable material used to detonate the nuclear chain reaction in the B-61. The “insensitive high explosive,” as it is called, creates a safer bomb by making it harder to detonate.

Few people argue that making safer bombs is bad, but opponents of the project criticize the considerable cost and say weapons laboratories working on the upgrades have a conflict of interest since they stand to profit from the government contracts.

Although the total cost of the project has already doubled and could end up costing even more, those in the military argue that the long term benefits of better protecting Americans outweigh the costs.
