Pentagon Reveals Plans for an Even Heavier and More Precise Bomb than the MOP, Capable of Destroying Fortified Underground Facilities with Surgical Impact.
The United States Air Force has taken a new step in the race for high-precision and mass destruction weaponry. The recent revelation of the operational use of the GBU-57/B bomb, also known as the Massive Ordnance Penetrator (MOP), marks a significant shift in the U.S. military’s posture towards fortified targets.
Now, plans point to an even bigger and more powerful weapon: the Next Generation Penetrator (NGP), which promises to raise penetration and destruction capabilities to a new level.
First Combat Use of the MOP
The MOP, weighing about 30,000 pounds, was first launched in real operations last weekend. During the action, called Operation Midnight Hammer, B-2 stealth bombers dropped 14 bombs on Iranian nuclear facilities. Twelve hit the Fordow complex, and two others were directed at Natanz.

The weapon carries a warhead of about 5,000 pounds and was designed to penetrate deeply buried structures, such as reinforced bunkers. It is estimated that it can penetrate over 60 meters of reinforced concrete.
Despite its weight and size, the attacks demonstrated precision, with post-operation images confirming that the targets were hit accurately.
Currently, only the B-2 Spirit bomber is authorized to carry and drop the MOP. Tests have also been conducted with the B-52, but the future of the weapon is linked to the B-21 Raider bomber, which is still under development.
New Generation of Warheads Underway
Despite the demonstrated effectiveness, the MOP has limitations. One of the main issues is the lack of propulsion, which requires a direct approach to the target, increasing risk for the aircraft.
Because of this, the Pentagon is already working on a more advanced successor: the Next Generation Penetrator.
According to documents released in February 2024, the Air Force requested proposals for a warhead weighing up to 10 tons, capable of causing multiple impacts: explosion, fragmentation, and deep penetration. The total weight and exact size of the new system have not yet been revealed.
More Precision, More Resilience
The new design does not focus solely on weight and destructive power. The precision of the new bomb must also surpass current standards.
The Air Force’s requirement is that the NGP have a Circular Error Probable (CEP) of only 2.2 meters, which means hitting the target with a 90% chance within 2.2 meters of the desired point.
This is a considerable leap compared to other systems, such as conventional JDAMs, which can have errors of up to 30 meters without GPS signal.
In addition, the weapon should be equipped with smart fuzes capable of withstanding impact and triggering the explosion at the exact moment, within the ideal depth.
Fuzes with sensors to count floors or detect internal spaces are deemed essential for hitting compartmentalized and protected targets.
Inspiration from Previous Studies
The foundation of the NGP project lies in analyses conducted since 2012, with updates in 2019. Unlike the MOP, initially created as an emergency response by the Defense Threat Reduction Agency, the new weaponry is planned as a complete system with potential for prolonged use.
Among the objectives is the inclusion of propulsion systems, possibly rockets, which would provide greater range to the bomb and reduce the need for aircraft to approach the target.
The idea is that the NGP can be launched from long distances, offering more safety and flexibility in operations.
Family of Weapons for Deep Attacks
The NGP may not just be a weapon but a new family of systems with different configurations, all integrated into the U.S. Long Range Strike strategy. This strategy includes other modern platforms such as the AGM-181A Long Range Stand Off (LRSO) missile and the B-21 Raider bomber.
The goal is to maintain U.S. superiority against highly protected targets, including underground complexes, at least through the 2030s.
The recent use of the GBU-57/B showed that deep penetration weapons have evolved beyond being mere deterrence tools.
Now, with the development of the Next Generation Penetrator, the U.S. makes it clear that they intend to expand their offensive capabilities with extreme precision weapons, great destructive power, and adaptability to the challenges of the modern battlefield.
The next generation of bombs will not only be larger—it will also be much smarter.
