US Accelerates Development of Nuclear Bomb 24 Times More Powerful Than Hiroshima

The United States has expedited the production of its B61-13 gravity bomb, a nuclear weapon with a destructive power 24 times greater than the atomic bomb dropped on Hiroshima in 1945. Weighing just 824 pounds, the bomb is capable of devastating a city center and causing catastrophic loss of life, with estimates suggesting up to three million casualties in an instant.
Originally slated for production in 2026, the timeline for the B61-13 has been accelerated by seven months due to what officials describe as a “critical challenge and urgent need” for a modern nuclear deterrent. Scientists at Sandia National Laboratories in New Mexico are leading the development of this advanced weapon, which relies on gravity for deployment from aircraft.
The urgency surrounding the B61-13 comes amid a global nuclear arms race, with nations such as Russia, China, North Korea, and Britain expanding their arsenals. While the total number of nuclear warheads worldwide has decreased since the Cold War, the number of combat-ready weapons has risen, signaling a renewed focus on nuclear capabilities.
Experts warn that this new era of nuclear competition is more complex and dangerous than the Cold War, as the number of nuclear-armed states has grown. Discussions about acquiring nuclear capabilities have emerged in countries like Germany, Poland, South Korea, Japan, and Saudi Arabia, further heightening global tensions.
Joseph Cirincione, a former national security advisor, has cautioned that the proliferation of nuclear weapons could lead to a “nuclear nightmare,” with ripple effects extending beyond Europe to Asia. Nations like Japan, South Korea, and Taiwan face growing concerns about the reliability of their defense agreements with the United States.
As geopolitical tensions rise, the development of the B61-13 underscores the United States’ commitment to maintaining its nuclear deterrent. However, the acceleration of its production highlights the growing urgency to address the challenges posed by an increasingly multipolar and nuclear-armed world.
