Summary: Ukrainian forces have reportedly intensified their military tactics against Russian air capabilities, claiming to have downed 11 Sukhoi Su-34 fighter-bombers and two Su-35 jets in Eastern Ukraine over a two-week period.

-Additionally, Ukraine has adopted aggressive strategies such as using drones to target Russian aircraft on the ground, including a notable attack on the Morozovsk airbase, housing Russia's 559th Bomber Aviation Regiment.

-The Su-34, known as "Fullback" by NATO, is a key asset in Russia's air force, capable of Mach 1.8 speeds and carrying a significant payload, but has not performed to expectations in the conflict. Despite these claims, the total impact and verification of these losses remain under scrutiny, highlighting the ongoing challenges Russia faces in sustaining its air operations against Ukraine.

Ukrainian officials earlier this spring claimed their forces took out at least a dozen of Russia’s most advanced fighter platforms over a two-week span. According to these claims, 11 Sukhoi Su-34 fighter-bombers and two Sukhoi Su-35 jets were shot down in Eastern Ukraine.

To make matters worse for Russia, Ukrainian forces have reportedly started to target these airframes on the ground. A flight of one-way explosive drones in April struck a Russian airbase in Morozovsk, one of Kyiv’s most unique attacks reported to date. The airbase is home to Moscow’s 559^th Bomber Aviation Regiment, making the lethal drone swarm especially significant. While these reports have not been verified, Ukraine’s drive to take out as many Sukhoi fighters as possible has clearly evolved.

An Overview of the Su-34

Designated by NATO as the “Fullback,” the Su-34 is one of Russia’s top warplanes. The Fullback features a platypus nose and side-by-side cockpit, characteristics that make the platform quite distinct. Two Saturn Al-31FM1 engines power the aircraft to a maximum speed of Mach 1.8. The fighter has a service ceiling of roughly 56,000 feet.

The Fullback was designed to lug a strong payload. The fighter can carry more than 17,000 pounds of weapons across 12 hardpoints located underwing and beneath the fuselage, alongside a 30 mm GSh-30-I cannon. It can carry Vympel R-27, R-73, and NPO-R-77 missiles, used primarily for defense against adversarial aircraft if detected by the rear-facing radar. The Fullback also carries an array of precision-guided and unguided bombs and rockets, including the KAB-500 laser-guided bomb.

The Fullback’s Performance in Ukraine

While the Kremlin often touts its Su-34 fighters as extremely advanced and deadly jets, they have not lived up to the hype in Ukraine. In fact, Moscow is losing warplanes far faster than it can afford. As of late February, the Russian air force had lost at least 31 of its 140 Su-34 fighters. According to an engineer with the RAND Corporation, however, these shootdowns only represent a portion of total losses. As explained in Forbes, “Overuse of these aircraft is also costing Russia as the war drags on. In a protracted war, where one force tries to exhaust the other, it's the total longevity of the military force that matters, and that's where the [Russian air force] finds itself now.”

Moscow is using its Fullbacks to drop KAB bombs over Ukraine. During a critical battle in the eastern city of Avdiivka this winter, Russian forces launched roughly 250 of these deadly weapons over a span of 48 hours. Thwarting this bombing capability is a top priority for the Ukrainians, since these weapons have the capability to destroy any position. Even if the recent drone swarming of the Morozovsk airbase was not as successful as Kyiv asserts, the tactic would likely reap benefits if carried out consistently.
