JAKARTA The United States launched airstrikes against three major Iranian nuclear facilities on Saturday, June 21, using the B-2 Spirit stealth bomber, one of the most advanced military aircraft in America's Arsenal. US President Donald Trump called the attack "very successful", and confirmed that Fordow's most important facility in Iran's nuclear program has disappeared.

The B-2 Spirit, which is designed to evade radar and penetrate the world's most advanced air defense system, was flown from the Whiteman Air Force Base in Missouri. The aircraft has a range of more than 11,000 kilometers without refueling and is capable of reaching any target in the world by refueling in the air.

In this mission, B-2 is equipped with a number of high-tech weapons designed to destroy facilities on the surface as well as those hidden deep underground. Among the main weapons used were the GBU-57A/B Massive Ordnance Penetrator (MOP), a 13-6 tonne bunker destroyer bomb, which was reportedly used by six units in destroying Fordow's site.

Massive Ordnance Penetrator is the largest conventional bomb in US weapons, developed specifically to destroy reinforced concrete bunkers and underground facilities. With more than six meters long and advanced GPS guidance systems, the bomb was capable of penetrating more than 60 meters of concrete before exploding with a high explosive power.

Delayed detonation technology allowed the bomb to reach its optimal depth before the explosion actually occurred, ensuring maximum destruction of targets protected underground.

Weight: 30,000 pounds (13,600 kg)

Length: 20.5 feet (6.25 meters)

Type: Bandster bunker destroyer (buker charter)

Technology:

GPS Guide System: Enables high precision targeting of underground bunkers.

Hulu Leak Delayed (Delayed-Action Fuze): Explodes after penetrating certain depths, not during the initial collision.

Special Penetrator Materials: Super Strong steel shells that allow penetration of up to 200 feet (61 meters) of reinforced concrete or hard rock.

How to work:

Launched from the height by B-2.

GPS directs the bomb to an underground target.

The bomb penetrates the surface of the ground and concrete.

The explosion occurred after reaching a maximum depth, destroying the underground facility directly.

In addition to MOP, B-2 also carries JDAM (Joint Direct Attack Munition) smart bombs, namely conventional gravity bombs modified with GPS and inertia guide systems. This technology allows bombs to hit targets with high accuracy within a radius of just a few meters. With the ability to strike multiple targets simultaneously, JDAM is the ideal choice to destroy static facilities such as command buildings or uranium enrichment centers.

Weight: 500 to 2,000 pounds (227 907 kg)

Type: Conventional bombs guided by precision

Technology:

Kit JDAM: The stupid bomb (dumb bomb) was turned into a smart bomb by adding a GPS and inertial (INS) module.

Inertial Guidance + GPS System: Ensure accuracy within a radius of 510 meters.

How to work:

JDAM was dropped from a height.

The INS/GPS system is active during free fall.

The bomb is directed automatically to the predetermined target coordinates.

To keep a safe distance from Iran's air defense system, the B-2 also launched the JSOW (Joint Stand-Off Weapon), an engineless glide bomb designed to glide remotely before hitting the target. With the folding wing and aerodynamic design, the JSOW can glide for more than 140 kilometers, while maintaining accuracy through the GPS navigation system.

Type: No engine long-distance glide bomb (glide bomb)

Jangkau Distance: Up to 80 nautical miles (148 km)

Technology:

Folding Wings: Open after launch to extend flight range.

INS/GPS Guideline System: Self-implementing the bomb to the target.

How to work:

Released from a safe distance beyond the reach of the enemy's defense system.

The open wing and the bomb glide aerodynamically to the target.

Avoid radar and air defenses because they are launched from outside the perimeter.

Meanwhile, the JASSM-ER (Joint Air-to-Surface Standoff Missile Extended Range) missile can also be deployed. This cruise missile has its own stealth design and is capable of reaching the target as far as 800 kilometers. With infrared sensors and radar avoidance technology, JASSM-ER is the ideal weapon to destroy strategic targets without having to enter enemy airspace.

Type: Long-range stealth cruise missile

Jangkau JASSM-ER Distance: Up To 500 miles (805 km)

Technology:

Stealth design: Shapes and materials are designed so that radar is not easily detected.

GPS/Inersia Driver + Infrared Image Sensor: For final correction and high accuracy.

Hulu Leak Penetrator: Effectively hitting a hard target or bunker.

How to work:

Launched from B-2 remotely.

Low-speed and low-speed glide missiles to avoid radar.

Infrared sensors help recognize and lock targets before hitting them with precision.

B-2 also has the ability to carry strategic nuclear weapons such as the B83 bomb, which can be configured for variable explosive power up to 1.2 megatons. Although nuclear weapons were not used in this attack, its presence strengthened B-2 status as the spearhead of American strategic beating power in its nuclear triad.

Type: Strategic nuclear gravity bomb

Explosion Power: Up to 1.2 megatons (can be regulated)

The number that B-2 can bring: Up to 16 units

Technology:

Daya Leak Settings (Variable Yield): Can be adjusted from small explosions to a maximum of 75 times stronger than the Hiroshima bombing.

Double Safety System: It won't be active unless it's in a strictly programmed condition.

How to work:

Dropped from the air like an ordinary gravitational bomb.

Exploded either when it touched the ground or at some level according to mission arrangements.

Its explosive power destroys very large areas, used only in strategic nuclear scenarios.

All of these advanced technologies are united on the B-2 stealth platform, which with an angular design and radar absorbing material, has radar tracks the size of a small bird. The aircraft is designed to enter undetected, destroy targets with precision, and exit enemy territory before ground radar or fighter aircraft can react.

The attack on Iran not only marks the use of the US's most advanced air force, but is also a serious signal of rising tensions in the Middle East region. For many observers, this operation shows that the United States still maintains its global air dominance through a combination of stealth technology, precision weapons, and layered military strategies.
