The Yakovlev Yak-52 (Russian: Яковлев Як-52) is a primary trainer aircraft originating from the Soviet Union. Its maiden flight occurred in 1976. Production took place in Romania under the name Iak-52 from 1977 until 1998 by Aerostar, which obtained manufacturing rights through an agreement within the former COMECON economic bloc. The Yak-52 was specifically developed as an aerobatic trainer for pilots within the Soviet DOSAAF program, which prepared both civilian sport aviators and military personnel. Today, the Yak-52 remains active in competitions such as the Fédération Aéronautique Internationale (FAI) World Aerobatic Yak 52 Championship, a renowned powered aircraft one-design aerobatic contest.
Design and development
Derived from the single-seat competition aerobatic aircraft, the Yakovlev Yak-50, the Yak-52 features an all-metal airframe powered by a Vedeneyev M14P nine-cylinder radial engine delivering 268 kW (360 hp).
Designed to function as a military trainer, its construction incorporates multiple elements reminiscent of early postwar fighter aircraft. These include a tandem cockpit configuration—with instrument panel layout, seat design, and canopy operation—tail structure, retractable tricycle landing gear, and mixed fuselage construction combining monocoque and steel tube frameworks. Additional features such as inner wing flaps, control placements, side fuselage access panels, radio antenna positioning, and overall dimensions closely resemble those of the jet trainer Yakovlev Yak-17 UTI (NATO reporting name Magnet).
The fuel and lubrication systems are engineered to support inverted flight for durations up to two minutes. Propulsion is provided by a two-bladed, variable-pitch propeller constructed from wood and fiberglass laminates, rotating counter-clockwise.
With an empty weight of approximately 998 kg (2,200 lb), the Yak-52 offers agile handling characteristics suitable for aerobatics while maintaining ease of operation and landing. It has competed internationally at advanced aerobatic levels. The airframe is rated for +7 and −5 G forces, capable of rolling rightward at speeds exceeding 180 degrees per second—measured up to 352 degrees per second—and can execute all maneuvers cataloged in the Aresti system.
Built to withstand rigorous conditions typical of Soviet military operations with minimal maintenance demands, the Yak-52 incorporates an extensive pneumatic system uncommon in Western designs. Pneumatic power actuates engine starting, landing gear retraction/extension, flaps, and wheel brakes. Air is stored in spherical bottles located behind the rear cockpit; these are replenished via an engine-driven compressor and monitored through cockpit instruments. Operating pressure ranges between 10 and 50 bars (145 to 725 psi). An emergency pneumatic circuit allows lowering of the landing gear if normal pressure is depleted or compressor failure occurs. Both main and reserve air bottles can be charged externally using compressed air sources such as scuba tanks. Ground steering and braking utilize differential braking controlled by rudder pedals combined with a hand lever on the control stick—a system requiring adaptation for pilots accustomed to hydraulic controls.
The retractable tricycle landing gear remains partially exposed when retracted, providing aerodynamic drag beneficial during descent maneuvers and extra protection during potential belly landings.
Several westernized variants have been developed featuring updated avionics, installation of three-blade propellers, upgraded M14PF engines rated at 298 kW (400 hp), and conversion to conventional tailwheel landing gear configurations known as the Yak-52TD. Aerostar also manufactures a factory-produced taildragger model called the Yak-52TW which includes two additional wing fuel tanks totaling 120 L (32 US gallons), the M14PF engine with three-blade propeller, electric start capability, and modern instrumentation.
On April 16, 2004, Russia introduced a modernized variant named Yak-52M, equipped with an updated M-14Kh engine, three-blade propeller, and other enhancements.
Though unarmed by design, during the Russian invasion of Ukraine, Ukrainian forces employed a Yak-52 to successfully intercept and destroy a Russian Orlan-10 reconnaissance drone near Odessa in April 2024. Additionally, on June 8, 2024, a ZALA drone was downed using this aircraft. Photographs shared on social media indicate that some Yak-52s have achieved multiple drone kills—up to eight confirmed in certain cases. The aircraft’s low stall speed allows it to pursue drones effectively and perform slow-speed maneuvers that enable a rear-seat gunner to engage targets at close quarters.

- Aerostar Condor
- A westernized adaptation proposed by Aerostar, utilizing a Lycoming O-540 engine.[2]
- Iak-52W
- A westernized model built by Aerostar, powered by either M-14P or M-14Kh engines but fitted exclusively with western instrumentation.
- Iak-52TW
- Produced by Aerostar, this westernized variant features either an M-14P or M-14Kh engine and replaces the nose wheel with a tail wheel. It incorporates fully western instruments, a significantly modernized wing allowing main gear retraction (though hydraulic brake components and parts of the main gear strut remain visible beneath the wing), and expanded fuel tanks holding up to 280 liters.
- Iak-52TD
- A modified Yak-52 developed by Termikas Ltd in Lithuania, equipped with a more powerful M-14PK engine and tailwheel landing gear. This variant includes wings integrated with aerobatic and ferry fuel tanks totaling 230 liters capacity, enabling full gear retraction without any components extending below the wing surface. Structural reinforcements were applied following Bulletin 60 (strengthened main spar fittings) and Bulletin 107 (installation of steel strap on main spar).
- UTL-450
- A Yak-52 derivative introduced by Motor Sich in 2016, powered by the AI-450S turboprop engine.
Civilian operators
- Yakitalia is an Italian civilian aerobatic squadron established in 1999.[3] Their fleet consists of three Yak-52s alongside one Yak-50.[4] The team operates from Fano “Enzo e Walter Omiccioli” Airport (LIDF), located in the Marche region.

Ukraine
Although the Yak-52 was not originally designed for air-to-air combat, its use during the Russo-Ukrainian conflict has seen it creatively adapted to engage and destroy UAVs.
On April 27, 2024, video footage captured near Odesa, Ukraine from a Russian drone’s perspective showed a Ukrainian-operated Yak-52 flying with the canopy open. The pilot maneuvered the aircraft in circles around the drone while a second crew member fired at it using a shotgun. Through this unconventional tactic, the Yak-52 reportedly achieved six confirmed kills against Orlan 10/30 series drones and two more against Zala 421-16E UAVs. Additionally, two drones were destroyed after being struck by lightning in front of the Ukrainian crew, and another was lost due to a birdstrike.
By June 2024, several Yak-52s operated by the Armed Forces of Ukraine displayed multiple drone kill marks representing both reconnaissance and strike UAVs, indicating that employing these aircraft in anti-drone operations had become standard practice. The typical combat setup includes a rear-seat gunner armed with an automatic rifle. Some of these planes are assigned to the Ukrainian Army Aviation's 11th Brigade, based in Kherson.
As of September 2025, an interview with a Yak-52 gunner revealed the presence of the 11th Brigade’s shoulder patch. In a separate interview that same month with the Wall Street Journal, Mykola Lykhatsky, deputy commander of the 11th Brigade, stated that piston-engine aircraft and helicopters conducting air-to-air interceptions account for approximately 10-12% of all Russian fixed-wing drones downed. The primary UAV targets include Orlan, Lancet, and Shahed models.
Russia
By 2025, the Yak-52 has been deployed by Russia to counter Ukrainian strike drones. On 21 October 2025, the Security Service of Ukraine released footage displaying two Russian light aircraft—a Yak-52 and a Cessna 172—camouflaged on the ground, which were subsequently destroyed by Ukrainian loitering munitions on 15 October 2025.[6][7]
