The Russian FAB-3000 with Extended 200 km Glide Kit: A Devastating Precision Weapon The FAB-3000, or Fugasnaya Aviabomba 3000, represents one of Russia's most formidable unguided aerial bombs from the Soviet era, now revolutionized by modern glide kits. Originally developed in the 1950s as a high-explosive demolition weapon, the FAB-3000 weighs approximately 3,000 kilograms (6,614 pounds), with a length of 3.84 meters and a diameter of 680 millimeters. Its warhead contains about 1,370 kilograms of TNT or a similar high-explosive filler, capable of generating a blast radius exceeding 200 meters and penetrating up to 1.5 meters of reinforced concrete. Designed for strategic bombing, it was historically dropped from heavy bombers like the Tu-22M3, but its revival in contemporary conflicts stems from integration with advanced guidance systems. The key transformation comes from the Universal Module for Planning and Correction (UMPK), a tail-mounted kit produced by Russia's Bazalt Design Bureau. The standard UMPK equips the bomb with folding wings spanning up to 3 meters when deployed, a streamlined fairing for aerodynamic stability, and a satellite-navigation system using GLONASS for mid-course corrections. This converts the inert FAB-3000 into a standoff glide bomb, extending its effective range from a mere free-fall drop to 50-60 kilometers when released from altitudes of 5,000-12,000 meters. Guidance achieves a circular error probable (CEP) of 10-30 meters, allowing strikes on bunkers, fortifications, and urban targets with minimal collateral risk compared to unguided variants. The kit adds roughly 200-250 kilograms, including control surfaces and inertial sensors, and is compatible with Su-34 fighter-bombers, which carry it externally on the centerline pylon. Recent upgrades have pushed the envelope further with the jet-powered UMPK-PD variant, achieving an extended range of up to 200 kilometers. This iteration incorporates a compact turbojet engine—sourced from commercial Chinese suppliers like the SW800Pro-Y—mounted in a tubular rear section, providing thrust for powered gliding. The design features enhanced aerodynamics with a curved, sloping tail and lighter composite materials, reducing drag by 20-30%. A 12-antenna controlled reception pattern antenna (CRPA) array bolsters resistance to electronic warfare jamming, ensuring reliable terminal guidance even in contested airspace. Released from high altitudes, the bomb rotates 180 degrees post-drop, deploying wings and igniting the engine for sustained propulsion, reaching speeds of 800-900 km/h. In operational terms, the FAB-3000-UMPK-PD has been combat-tested in eastern Ukraine since mid-2025, targeting deep rear-area logistics and command nodes. Its 1.4-ton explosive yield can level multi-story buildings or crater runways, while the standoff capability shields launch aircraft from ground fire. Production ramps up at facilities like the Izhevsk Mechanical Plant, with monthly outputs exceeding 500 units. However, challenges persist: the bomb's mass limits fuel efficiency, capping practical range at 150-180 kilometers under load, and vulnerability to advanced air defenses remains a concern. Nonetheless, this evolution underscores Russia's shift toward affordable, mass-produced precision munitions, blending Cold War brute force with 21st-century lethality.

“One of the most complicated hostage rescue missions in history.” The operation to rescue the hostages from Nusayrat was named "Summer Seeds" and is defined by the IDF as one of the most complex ever for hostage rescue. The hostages were held in a heavily civilian populated area, above ground, in buildings of 3-4 stories. The forces stormed the two separate targets where the hostages were held, with Noa held on the first floor and Andrey, Shlomi, and Almog on the third floor of another building, hundreds of meters apart. Hamas moved the four hostages from apartment to apartment, and the concern was that if the forces only stormed one building, the terrorists would escape with the hostages in the second building. The Air Force gathered intelligence from the air in the last few days, and the IDF and Shin Bet created conditions to reach the targets without the terrorists shooting the hostages first, which was key to the operation's success. The models built by the Yamam (Israel's counter-terrorism unit) reminded senior military officials of the models established for the Entebbe operation, with buildings, streets, and small areas for practice. The main problem was in the apartment where Andrey, Almog, and Shlomi were held, and where Yamam fighter Arnon Zamora was killed. The rescue took place under heavy fire, and during the disengagement, dozens of terrorists with RPGs and machine guns ran through the alleys towards the targets. As a result, uninvolved Gazan civilians were also killed in the dense fire exchange. The military said, "The difference between success and failure in such an operation is a hair's breadth, and we relied on exceptional technology from the Intelligence and Shin Bet. Without ground activity and maneuvering in the Gazan area, it would not have been possible to succeed in such operations." The IDF also noted that the rescue was made possible by Commander Zamora's heroism. "Shin Bet and Intelligence Directorate fighters entered the lion's den in the refugee camp and dismantled houses in areas where we hadn't maneuvered," they said. "This is bravery on the level of Judah Maccabee. The operation was planned for weeks with drills, rescue plans, and fires executed, alongside scenarios of cases and responses." The forces simultaneously broke into the two houses with special weapons developed for the operation. Immediately after extracting the hostages, the forces began to withdraw while fighting dozens of terrorists, but a vehicle with the three hostages got stuck and came under heavy fire. Division 98 forces jumped in to assist in the vehicle rescue battle, and rescue helicopters entered deep into the strip in daylight. Three brigades participated in the rescue battle, during which Zamora was also evacuated to the hospital: Brigade 7, Paratroopers, and Kfir with Flotilla 13, along with other special forces. "The fire plan that was executed was focused but extremely powerful," the IDF added. "The cooperation with Shin Bet and Yamam rose to several levels into a single operational system, under the direction of the Shin Bet chief and the Chief of Staff. Four keys to the operation: deception, surprise, determination, and power." To maintain the secrecy of the operation, thousands of soldiers in the brigades that participated in the rescue were unaware of the nature of the operation before it happened to preserve the element of surprise. Only a handful of commanders were exposed to the operation yesterday, at various levels. These forces were positioned at the correct launch points without revealing the secret. During the operation, soldiers were also lightly injured, mainly from shrapnel.
