Ukraine has expanded its campaign of long-range strikes against Russian Su-34 bomber fleets and UMPK glide bomb production facilities throughout May 2026. This strategy seeks to neutralize the Russian Federation’s most destructive tactical weapon by eliminating the launch platforms and munitions before they reach the front lines.
The conflict in Ukraine has entered a phase where the Russian Aerospace Forces (VKS) rely heavily on the UMPK (Universal Glide and Correction Module). These kits convert standard “dumb” bombs, such as the FAB-500 and FAB-1500, into glide munitions capable of striking targets from distances that keep Russian aircraft largely outside the reach of most Ukrainian short- and medium-range air defenses.
Because these bombs lack the precision of cruise missiles and are difficult to intercept once released, the Ukrainian General Staff has shifted its focus from point-defense to a strategy of attrition targeting the entire launch chain. This approach targets the Su-34 aircraft, the airbases where they are stationed, and the factories where the UMPK modules are fitted to old Soviet-era munitions.
Targeting the Su-34 Launch Platforms
The Su-34 full-back serves as the primary delivery vehicle for glide bombs. By operating from airbases deep within Russian territory—specifically in the Voronezh and Belgorod regions—these aircraft can release their payloads and return to base without entering Ukrainian airspace. To counter this, Ukraine has increased the use of long-range precision munitions and domestically produced drones to strike these airfields.
The objective is to force the VKS to move its aircraft further away from the front. Increasing the distance between the launch point and the target reduces the effective glide range of the bombs and increases the flight time for the bombers, making them more vulnerable to detection and attack. Military analysts note that the loss of a single Su-34 is significantly more costly for Russia than the loss of several glide bombs, as the aircraft are harder to replace than the munitions.
Recent operations have focused on the runways and hardened aircraft shelters of these bases. By damaging the infrastructure, Ukraine limits the number of sorties the VKS can conduct daily, directly reducing the volume of tonnage falling on Ukrainian fortifications in the Donbas.
Disrupting the UMPK Production Chain
The UMPK is not a new bomb but a modular kit consisting of wings and a guidance system attached to existing FAB (high-explosive aviation bomb) or KAB (guided aviation bomb) stocks. This allows Russia to utilize massive quantities of Cold War-era munitions with modern accuracy. The “remedy” identified by Ukrainian intelligence involves striking the facilities where these conversions occur.
Ukraine has targeted assembly plants and storage depots where the UMPK modules are paired with the heavy bombs. These sites are high-value targets because they represent a bottleneck in the Russian logistics chain. If the conversion process is disrupted, the VKS is forced to return to “dumb” bombing, which requires flying directly over targets and exposes pilots to a much higher risk of being shot down by man-portable air-defense systems (MANPADS).
The goal is to break the cycle of production and delivery. We cannot stop every bomb in the air, but we can stop the bomb from being built or the plane from taking off.

The Role of Long-Range Munitions and Drones
The shift toward deep strikes has been enabled by a combination of Western-supplied missiles and indigenous Ukrainian technology. The use of ATACMS (Army Tactical Missile System) and Storm Shadow/SCALP-EG missiles allows Ukraine to hit command centers and airfields deep inside Russia with high precision.
Alongside these, Ukraine has deployed the Palianytsia
rocket-drone, a long-range weapon designed specifically to strike strategic targets in the Russian rear. These drones provide a low-cost alternative to expensive missiles, allowing Ukraine to maintain a constant pressure campaign against Russian aviation infrastructure without depleting its stockpile of precision missiles.
This multi-layered approach creates a dilemma for the Russian military. To protect their airbases, they must divert air defense systems from the front lines to the rear. If they do not, they risk losing the Su-34 fleet. If they do, the Ukrainian ground forces face less pressure from Russian air superiority during offensive operations.
Strategic Impact on Frontline Fortifications
The UMPK glide bombs have been the primary tool used by Russia to dismantle Ukrainian defensive lines. The sheer mass of a FAB-1500, which carries a payload of roughly 1,500 kilograms of explosives, can destroy reinforced concrete bunkers that are otherwise impervious to standard artillery.
By reducing the frequency of these strikes, Ukraine is attempting to preserve its manpower and structural defenses. The ability to maintain intact fortifications allows Ukrainian forces to hold positions longer and reduces the need for costly retreats under the pressure of aerial bombardment.
However, the effectiveness of this counter-strategy depends on the scale and consistency of the strikes. Russia continues to produce UMPK kits in large numbers, and the VKS possesses a significant fleet of bombers. The battle is now one of industrial and operational attrition: whether Ukraine can destroy Su-34s and production plants faster than Russia can replace them.
Remaining Uncertainties
Several variables remain that could alter the effectiveness of this strategy. First, the extent of Western permissions for the use of long-range weapons inside Russian territory continues to fluctuate, which affects the frequency of strikes on airbases. Second, Russia may attempt to develop more advanced glide munitions with even longer ranges, further pushing their aircraft away from the danger zone.
Furthermore, the integration of more advanced air defense systems, such as the Patriot and SAMP/T, provides a secondary layer of protection, but these systems are primarily designed for missiles and aircraft, not the low-signature glide of a FAB bomb. The primary defense remains the destruction of the bomber before it ever reaches the release point.
