USA Begins Production of Nuclear Warhead 24 Times More Powerful Than Hiroshima Bomb. Project Reignites Discussions on Armament and Global Balance

The United States will start production of its newest nuclear bomb earlier. The weapon, named B61-13, was developed by Sandia National Laboratories (SNL) and is part of the country’s nuclear arsenal modernization plan.

According to an official statement, the total production of the B61-13 will begin seven months ahead of schedule. The SNL stated that this was only possible due to an “innovative program planning,” which accelerated the timeline by over 25%.

This advancement reinforces the USA’s efforts to maintain its nuclear deterrence capacity amid international tensions. Even with the reduction in the number of nuclear weapons since the end of the Cold War, the USA, Russia, and China continue to invest in advanced military technology.

A New Generation of Nuclear Warhead

The B61-13 is a gravity nuclear bomb. This means it is dropped from an airplane and does not have self-propulsion. According to the National Nuclear Security Administration (NNSA), the project started in 2023. The total investment in the weapon reached US$ 92 million.

The new model is a variant of the older B61-7. The difference lies in the safety systems and the embedded technology. The B61-13 will have a tail kit that allows it to guide itself to the target after being launched.

Moreover, it is a variable yield nuclear bomb. This means its destructive power can be adjusted before launch. The yield can vary from 10 to 360 kilotons. For comparison, the bomb dropped on Hiroshima had a yield of 12 to 18 kilotons. The one on Nagasaki, between 18 and 23.

With this new capability, the bomb can be used more precisely, targeting specific objectives and reducing collateral damage. The B61-13 surpasses earlier models, such as the B61-12, which has a maximum yield of 50 kilotons.

Modernization of Arsenal Without Increase in Warheads

The introduction of the B61-13 is part of a replacement process. It will replace older versions, such as the B61-7 and B61-12. This way, the USA can maintain a more efficient arsenal without raising the total number of warheads.

The B61 bomb is the oldest nuclear weapon of the United States still in use. It has been active since 1968 and has undergone several life extension programs. The new version represents a continuation of this history, now with more modern technology.

Initially, the B61-13 will be transported by the B-2 Spirit bomber. Later, it will be incorporated into the new B-21 stealth bomber from manufacturer Northrop Grumman.

Strategic Role in Global Tension Scenario

The early arrival of the B61-13 occurs at a time of global instability. The war in Ukraine, China’s advancements in its nuclear capability, and the recent political stances adopted by the USA heighten the atmosphere of alert.

Even with the number of nuclear weapons declining in recent years, the arsenals of the USA and Russia still hold about 5,000 warheads each. The introduction of the B61-13 marks an important update in this race for cutting-edge military technology.

The development of the new warhead indicates that the United States intends to maintain its deterrent strength with more precise, modern, and secure armament.

Strategic Role in Global Tension Scenario

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

A giant brown band visible from space, approximately 8,850 kilometers long, connected Africa to America in the Atlantic Ocean, and satellites revealed that it is neither land nor pollution, but the largest accumulation of seaweed in the world, which broke records in 2025.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

In just one cast, fishermen are surprised to capture 14,096 mullets in Bombinhas and close a historic season with 58,000 fish; scene recorded in the Santa Catarina paradise marks the last day of the 2026 season.

Using high-resolution satellite images, archaeologists rediscovered the Egyptian city of Imet, buried for centuries in the Nile Delta, revealing rare multi-story houses, granaries, and a sacred road linked to the cobra goddess Wadjet, from about 2,400 years ago.

Greek island offers free housing for volunteers, but there’s a condition: you need to take care of rescued cats.

Motorcyclist sees excavator arriving at the edge of a river in Bosnia, calls neighbors in minutes and turns a hydroelectric project into a resistance lasting more than 10 years with five expired concessions.

A mother who worked as a recycler took money from her own food to put credit on her daughter’s broken-screen cell phone; now Débora has been accepted into medical school at two universities and wants to save hearts in the operating room.

The government opens the budget to pay pensions and ends up targeting precisely the FAB’s Gripen fighter jet; the reason for the R$ 800 million block reveals a fragility that has haunted the country’s defense projects for decades.

A property that once had more than 1,000 hectares now operates with 73 hectares and invests in coffee, cattle, photovoltaic energy, and hydroponic corn to prove that a small farm can also be profitable.

A potato-shaped object over a mountain and orbs multiplying in the sky are among the 72 new files from the Department of Defense that do not prove extraterrestrial life.

Family struggling with the electricity bill at the end of the month finds an air conditioner that consumes little and costs only R$ 21 per month; LG device cools the room 40% faster and also comes with a detail that grabs attention.
