Full Specifications

GBU-72 Advanced Penetrator Bomb

The GBU-72 Advanced 5K Penetrator is a next generation U.S. precision guided bunker buster bomb developed to destroy hardened and deeply buried targets. Designed for modern high intensity warfare, the weapon provides improved penetration capability over older systems such as the GBU-28. The bomb is intended for use against fortified underground facilities, command bunkers, weapon storage sites, and protected infrastructure.

The GBU-72 combines a heavy penetrating warhead with precision guidance technology, allowing U.S. and allied air forces to strike hardened targets with greater accuracy and survivability. The weapon is compatible with several advanced combat aircraft, including stealth platforms capable of penetrating contested airspace.

Manufacturer

The GBU-72 was developed primarily by Northrop Grumman for the United States Air Force. The bomb integrates a BLU-137 penetrating warhead and advanced guidance systems designed to improve accuracy during high speed delivery missions.

The United States accelerated development of the bomb to address evolving underground threats and heavily fortified military infrastructure. Testing has included deployment from aircraft such as the F-15E Strike Eagle and evaluations for compatibility with the F-35 Lightning II.

Speed and Range

The GBU-72 itself is an air dropped gravity bomb and does not possess independent propulsion. Its operational range depends on the launch altitude, speed, and delivery platform. When released from high altitude fighter aircraft, the weapon can travel significant stand off distances using guidance fins and glide characteristics.

The bomb uses a GPS aided inertial navigation guidance system, enabling accurate strikes in all weather conditions. Its penetrating warhead is engineered to defeat reinforced concrete and underground facilities before detonation.

Cost/Price

Exact unit pricing for the GBU-72 remains classified. However, defense analysts estimate the cost of each bomb and associated guidance kit to be several hundred thousand U.S. dollars depending on configuration, procurement volume, and integration requirements. Development and testing programs have involved multi million dollar contracts awarded by the U.S. Department of Defense.
