Overview of the GBU-76/B Bomb Development The article discusses the development of the GBU-76/B, a next-generation bunker-busting bomb by the U.S. military, designed to target deeply buried underground facilities. This weapon is an evolution of the GBU-50, a precision-guided bomb already in use, with enhanced capabilities to destroy hardened targets like bunkers, command centers, and underground storage facilities. --- Key Features and Capabilities Precision Guidance System: The GBU-76/B employs advanced GPS and inertial navigation systems for high accuracy, ensuring it can strike targets with minimal collateral damage. It is equipped with a retrograde propulsion system, allowing it to penetrate up to 30 meters of reinforced concrete or rock, making it effective against underground structures. Targeting Underground Facilities: The bomb is specifically designed to neutralize subterranean bunkers, tunnels, and underground storage sites—targets that are traditionally difficult to destroy with conventional munitions. Its ability to "crush" hardened targets makes it a critical tool for counterterrorism and strategic deterrence. Cost and Deployment: Cost per bomb: The GBU-76/B is significantly more expensive than the GBU-50, with estimates ranging from $13 million to $15 million per unit (equivalent to 100 crore to 150 crore rupees). Delivery Platform: Only the B-2 stealth bomber can carry this weapon due to its size and weight. A single B-2 can carry up to two GBU-76/B bombs, with each mission costing $20–30 million (160–250 crore rupees) due to fuel, maintenance, and operational costs.#us_air_force #gbu_76_b #b_2_stealth_bomber #underground_facility #gbu_50
