Russia deployed heavy FAB-3000 glide bombs against Ukrainian positions on March 17, 2026, escalating its air campaign as mass air strikes become the primary weapon against Ukrainian fortifications. The upgraded bombs, converted from Soviet-era gravity bombs with glide kits, can be launched from aircraft outside Ukrainian air defense range. The FAB-3000 carries approximately 3,000 kilograms of explosives, making it one of the most destructive weapons in Russia’s arsenal.
The use of heavy glide bombs represents a significant escalation as Russia seeks to break through prepared Ukrainian defensive positions. These weapons can destroy hardened fortifications and underground facilities that would survive smaller munitions. Ukrainian military officials have warned that defending against mass glide bomb attacks requires resources that are in short supply.
Russia is using the heaviest conventional bombs available to destroy our fortifications. These strikes can reduce entire defensive positions to rubble.
Air Campaign Strategy
Russia has increasingly relied on air-delivered glide bombs as its primary weapon for attacking Ukrainian fortifications. The glide bombs can be launched from aircraft operating at high altitude outside the range of most Ukrainian air defense systems. This allows Russia to attack targets deep behind Ukrainian lines without risking aircraft.
Defensive Challenges
Ukraine faces significant challenges defending against mass glide bomb attacks. Air defense systems capable of shooting down aircraft launching these weapons are in short supply. Ukrainian forces have been forced to dig deeper fortifications and create redundant defensive positions, but the sheer size of the FAB-3000 makes most shelters inadequate.
