In May 2026, the VKS (Russian Air Force) dropped, on average, roughly 240 UMPK-guided bombs per day, for a monthly total of 7,496 bombs. Such an effort would have required approximately 60 Su-34 sorties per day, with each fighter-bomber carrying four bombs. Assuming two sorties per day per aircraft, a minimum of 30 fighters would have had to be serviceable every day. Assuming a 50 percent serviceability rate, the bombing effort suggests that the number of Su-34 fighter-bombers committed to the Special Military Operation exceeds 60.
Open-source estimates suggest that, as of early 2025, the VKS operated between 150 and 180 Su-34s.
Each Su-34 strike mission is reportedly provided top cover by a Su-35 mission.
From the above, it would be reasonable to conclude that VKS participation in the ongoing conflict is substantial and creditable, but still well short of its full potential.
Kometa-M and Improved Bomb Accuracy
Notably, the accuracy of Su-34 strikes has improved considerably over the past few months, most likely because of the use of more EW-resilient SATNAV modules.
Russia has reportedly developed a 12-channel satellite-navigation system known as Kometa-M. Each Kometa module uses real-time signal processing to automatically "null out" (cancel) electronic-warfare jammers attempting to overwhelm satellite signals. It does so while maintaining clear reception from genuine satellites in other directions. As long as the number of separate jammers targeting the module remains below approximately 12, the system continues to provide accurate navigation. Similarly, when encountering spoofing attacks, the module checks the direction of incoming signals and rejects fake transmissions originating from the ground rather than from orbit.
Scale of VKS Bombing Operations
The scale of the bombing campaign is made possible not only by the size of the Su-34 fleet but also by the aircraft's unusually strong payload-range characteristics.
The Su-34 can reportedly carry six bombs, instead of just four. However, it cannot carry six UMPK bombs because of stability issues. Instead, the fighter-bomber can be configured to carry a combination of four UMPKs and two UMPB D-30SN bombs. (UMPB stands for Universal Interspecific Glide Ammunition. UMPB can be dropped by fighters or launched using Tornado-2 MLRS rockets.)
According to the Fighterbomber Telegram channel, the VKS is currently dropping approximately 10,000 bombs per month. If Su-34s could be routinely configured to carry six bombs, monthly bomb delivery could potentially increase to 15,000–16,000 bombs.
Why the Su-34 Is an Effective Strike Aircraft
Another interesting point is that the Su-34 has one of the longest ferry ranges of any fighter aircraft in the world, estimated at between 4,800 and 5,000 km on internal fuel alone. Fitted with three 3,000-litre drop tanks, its ferry range increases to an estimated 8,000 km.
The Su-34 is an adaptation of the Soviet Su-27 air-superiority fighter optimized for the strike role. The fighter-bomber is approximately 50 percent heavier than the Su-27. However, the performance penalty associated with the additional weight is mitigated by an aerodynamically refined airframe, the use of the more powerful and fuel-efficient AL-31FM2 engine, and a greater use of composite materials.
The AL-31FM2 is a non-thrust-vectoring engine that delivers better overall performance than the thrust-vectoring AL-31FP fitted on the Su-30SM. It produces 14.5 tonnes-force (142 kN) in afterburner compared with the AL-31FP's 12.5 tonnes-force (122.6 kN), giving the Su-34 superior acceleration, climb rate, and payload-range performance in its strike-bomber role.
Besides its extraordinary range, the Su-34 also stands out as the only twin side-by-side seat fighter aircraft of the world.
Despite side by side seating, there is space between the pilot seats to spread a mattress, allowing one of the crew members to rest during a flight. Space behind the pilots’ seats allows them to stand up to their full height.
There is a microwave oven, an air conditioner, an electro-massage system built into the pilots’ seats and even a bio toilet aboard the bomber.
Reconnaissance Variant
In a statement released on July 7, 2025, Rostec stated, "the Su-34 can also be used to perform aerial reconnaissance tasks."
For tactical reconnaissance missions, the Su-34 uses the Sych family of externally mounted modular pods to enable the aircraft to perform electronic, radar, and optical intelligence gathering without compromising its primary combat capabilities.
The Sych family comprises 3 pods - UKR-RT, UKR-RL and UKR-OE.
UKR-RT: This variant is dedicated to signals intelligence (SIGINT). It intercepts and analyzes enemy radio and radar emissions, identifying electronic signatures of ground-based and airborne systems.
UKR-RL: Focused on radar reconnaissance, this pod houses a side-looking synthetic aperture radar (SAR). It can map terrain and moving targets in all weather conditions, day or night, offering detailed battlefield awareness and enabling strike planning even in GPS-denied or obscured environments.
UKR-OE: This electro-optical pod combines TV, infrared (IR), and laser rangefinder/designator systems. It is used for high-resolution imagery of ground targets, surveillance of enemy positions, and target acquisition—particularly useful in precision strike missions or battle damage assessment.
Together, these Sych pod variants transform the Su-34 into a multi-role ISR platform capable of supporting deep strike, situational awareness, and electronic warfare missions.
