The Ukrainian Defense Forces used domestically developed weapons to strike targets in Russia’s Moscow region, hitting a microchip factory and an oil pumping station, the General Staff of Ukraine reported.
According to the report made on Telegram, early on Sunday morning, May 17, Ukrainian units carried out strikes on a range of high-value Russian targets.
The General Staff said Ukrainian-made systems – including the RS-1 “Bars,” FP-1 “Firepoint,” and BARS-SM “Gladiator” unmanned systems – were used in the operation.
The Bars drone-missile is built in a mid-wing configuration with a wingspan of about 2 meters. The fuselage is made of composite materials and consists of a minimal number of parts, significantly speeding up production and reducing manufacturing costs.
It has an estimated range of 700-800 km (about 435-500 miles) and carries a warhead of approximately 100 kg (around 220 pounds) or slightly less.
Although officially described as a “drone-missile,” experts say the designation reflects bureaucratic considerations. Classifying it as a drone simplifies and accelerates approval for deployment compared to traditional missile programs.
The FP-1 is a Ukrainian long-range strike unmanned aerial vehicle (kamikaze drone) developed by Fire Point in cooperation with the Ukrainian-Czech company UAC.
It is designed to strike strategic targets deep inside enemy territory at ranges of up to 1,600 kilometers (about 994 miles), carrying a warhead of up to 113 kilograms (about 249 pounds).
The FP-1 production process is optimized for mass production of expendable strike drones. The use of plywood structural elements and simplified assembly techniques allows for fast and cost-efficient manufacturing.
In mid-March 2026, Fire Point introduced upgraded FP-1 variants adapted to carry air-defense payloads for intercepting aerial targets. These modifications reportedly enable the drone to transport FPV interceptors, machine-gun systems, and potentially missile systems, including man-portable air-defense systems (MANPADS).
The military leadership thanked the personnel of the 412th Separate Unmanned Systems Brigade, the 107th Rocket Artillery Brigade, the 19th “Saint Varvara” Missile Brigade, and other units of Ukraine’s Defense and Security Forces for their involvement.
As a result of the strike near Moscow, the Angstrom enterprise in Zelenograd was hit. The facility produces microcircuits for precision weapons and is considered an important element of Russia’s military-industrial complex. It is also under strict US sanctions due to its role in supplying semiconductors for military use.
In addition, the Solnechnogorsk pumping station, a key part of the Moscow ring oil pipeline system used to supply fuel to Russian forces, caught fire following the strike.
Alongside deep-strike operations, Ukrainian forces also targeted Russian positions on the front line and in border areas.
These included a Russian command post in the Bunge district of Donetsk region, drone control points in Kharkiv, Donetsk, and Kherson regions, as well as concentrations of Russian manpower in the Zaporizhzhia region, and in Volfino, Kursk region of Russia.
“The Defense Forces of Ukraine will continue to systematically take measures to completely stop the armed aggression of the Russian Federation against Ukraine,” the General Staff said.
Earlier, the Security Service of Ukraine (SBU), in coordination with the Armed Forces of Ukraine (AFU), claimed responsibility for a major weekend air campaign that penetrated air defenses around Moscow.
SBU head Maj. Gen. Yevhenii Khmara said operators from the Center for Special Operations “Alpha” carried out simultaneous strikes on heavily protected industrial facilities and military airfields.
While Russia’s Defense Ministry said more than 550 Ukrainian drones were intercepted across 14 regions overnight, SBU data and flight logs indicate that several high-value targets in the Moscow region were successfully hit.
Among them was the Angstrem semiconductor plant in Zelenograd, a key hub for domestic electronics manufacturing. In parallel, a strike on the Moscow oil refinery in the Kapotnya district triggered an explosion, reportedly injuring 12 workers and disrupting fuel processing.
Additional strikes hit oil pumping and storage facilities in Solnechnogorsk and Volodarskoye – critical nodes in the fuel supply network serving the Moscow region.
“These operations are of critical importance for weakening the military potential of the Russian Federation,” Khmara said, adding that bringing the war closer to Moscow undermines the Kremlin’s sense of internal security.
