Ilyushin Il-2 Sturmovik — Ground-attack aircraft
Open in interactive gallery →

The Ilyushin Il-2 Shturmovik (Штурмовик, "ground-attack aircraft") is a Soviet single-engine, two-seat (later one-seat / two-seat hybrid), low-wing, all-metal armoured ground-attack aircraft designed by Sergey Ilyushin at the Ilyushin Design Bureau and produced from 1941 to 1945. With around 36,183 airframes built across multiple variants, the Il-2 is the most-produced military aircraft in history — exceeding the production of any single fighter or bomber type during WWII. The aircraft was the principal Soviet close-air-support and anti-armour platform throughout WWII and central to Soviet ground-operations doctrine.

The first Il-2 (TsKB-55 prototype) flew on 2 October 1939. The aircraft was designed to a 1938 specification calling for a heavily-armoured ground-attack aircraft ("flying tank") capable of surviving sustained ground-fire while delivering accurate strikes against German armour. Its distinctive feature was the all-metal armoured cockpit / engine compartment — the aircraft was effectively built around a structural armoured "bathtub" of 4-12 mm steel and aluminium alloy plate that protected the pilot, engine, fuel tanks, and oil cooler. This armoured shell could absorb 20mm cannon fire, small-arms fire, and most ground-fire encountered in 1941-1942 combat — dramatically increasing pilot survivability over conventional unarmoured ground-attack aircraft.

The Il-2's combat record covers the entire Eastern Front from June 1941 to May 1945. Early sorties were difficult: the single-seat configuration left the pilot vulnerable to rear attack by German fighters, and Il-2 losses were high during the 1941-1942 period. Introduction of the two-seat Il-2M3 variant (with a rear gunner operating a 12.7mm UBT machine gun) from late 1942 sharply improved survivability. The Il-2 played central roles in the Battle of Stalingrad (November 1942 - February 1943), the Battle of Kursk (July 1943, the largest tank battle in history — Il-2 squadrons used PTAB anti-tank submunitions to devastating effect against German Panther / Tiger formations), and the entire Soviet advance from Stalingrad through Berlin (1943-1945). Stalin himself remarked that "the Il-2 is as important to the Red Army as bread and water" — a quote frequently used in Soviet propaganda.

Major variants included the early single-seat Il-2 (1941), the two-seat Il-2M3 (most-numerous variant), the Il-2T (torpedo-bomber), and the post-war Il-10 (improved successor design with retractable landing gear, more-powerful engine, similar armament). Production was concentrated at the Voronezh and Kuybyshev (now Samara) airframe plants. Around 30,000 Il-2 / Il-10 airframes were lost in WWII combat — the highest combat-loss total of any Soviet aircraft type. Roughly 9 Il-2 airframes survive globally (no airworthy in 2026); major static specimens are at the Central Russian Air Force Museum (Monino), the Polish Aviation Museum (Kraków), and the Yad Vashem Holocaust Memorial (Jerusalem).

For Kids — a shorter, friendlier version

The Ilyushin Il-2 Sturmovik was a Soviet ground-attack plane from World War II. It first flew in 1939 and entered Soviet service in 1941. About 36,183 Il-2s were built between 1941 and 1945, the most of any military aircraft in history. The Sturmovik was nicknamed the flying tank because of its heavy armor.

The Il-2 is 39 feet long with a 47-foot wingspan, longer than a school bus. One Mikulin AM-38 piston engine makes 1,720 horsepower. Top speed is 257 mph, faster than most cars on a highway. The plane carries up to 1,322 pounds of bombs, plus rockets, machine guns, and cannons.

The Il-2's secret was its armor. Thick steel plates of 4 to 12mm protected the pilot, engine, and fuel tanks from German bullets and small cannon fire. The plane could survive hits that would down most other ground-attack aircraft. The cockpit was built inside a steel armored bathtub.

Il-2s flew in nearly every Soviet WWII operation. They attacked German tanks at the Battle of Stalingrad, the Battle of Kursk (the largest tank battle in history), and the final attack on Berlin in 1945. Soviet leader Stalin called the Il-2 as important as air and bread to the Soviet Army. Without the Sturmovik, the Soviet Union may have lost the war.

Kids’ Questions

Why so many built?

The Il-2 was the main Soviet ground-attack plane in WWII. Every Soviet army needed Il-2s to attack German tanks and troops. Soviet factories worked day and night to build them. 36,183 Il-2s were made between 1941 and 1945, more than any other military plane ever. The Soviets needed so many because the Il-2 saw heavy combat and many were lost.

What is a flying tank?

Most planes have thin metal skin that bullets pass right through. The Il-2 has 4 to 12mm thick steel plates around the pilot, engine, and fuel tanks. This armor stopped most German bullets and small cannon fire. The Il-2 could survive hits that would down other planes, like a flying tank.

How did it help the Soviet Union win?

The Il-2 attacked German tanks, trucks, and artillery from low altitude. By the end of WWII, the Il-2 had destroyed thousands of German tanks. At the Battle of Kursk (the biggest tank battle in history) in 1943, Il-2s helped stop the German attack. Stalin called the Il-2 as important as air and bread, meaning the Soviet Army could not have won without it.

Variants

Il-2 (single-seat, 1941-1942)
Initial production variant. Mikulin AM-38 engine (1,600 hp). Single-seat configuration without rear gunner. ~5,000 built before transition to two-seat. High loss rate to German fighters drove the two-seat upgrade.
Il-2M (1942)
Improved single-seat variant with strengthened armour, increased fuel capacity, and 23mm VYa cannon (replacing 20mm ShVAK). Limited production; quickly superseded by two-seat Il-2M3.
Il-2M3 (two-seat, 1942-1945)
Most-numerous variant. Two-seat configuration with rear gunner operating 12.7mm UBT machine gun. AM-38F engine (1,720 hp). 2 × 23mm VYa cannon + 2 × 7.62mm ShKAS machine guns + 600 kg of bombs / 8 × RS-82 / RS-132 rockets. Backbone of late-war Soviet ground-attack force. ~26,000 built.
Il-2T
Torpedo-bomber variant. Used by Soviet Naval Aviation (VVS-VMF) for anti-shipping operations against German Baltic / Black Sea naval forces. ~200 built.
Il-10
Post-war successor design. Retractable landing gear, improved aerodynamics, AM-42 engine (2,000 hp), top speed 350 mph. Service entry 1944 (limited combat use); produced through 1955 (Soviet) and 1956 (Czechoslovakia, as Avia B-33). ~6,300 Il-10 + ~1,200 Avia B-33 built. Backbone of Eastern Bloc ground-attack force into the 1960s.

Notable Operators

Soviet Air Force / Soviet Naval Aviation
Primary operator. Il-2 served on the entire Eastern Front from Operation Barbarossa (June 1941) through Berlin (May 1945). Around 250 Il-2 regiments in frontline service at peak deployment. Il-2 squadrons fought at Stalingrad, Kursk, Operation Bagration, the advance to Berlin, and Manchuria operations against Japan.
Foreign WWII operators
Polish (Polish 1st Tactical Air Army, organised by Soviet forces, ~250 Il-2s), Yugoslav (Yugoslav Partisan air force, post-war Yugoslav Air Force), Mongolian People's Republic (limited use 1945 against Japanese forces).
Post-war / Cold War operators
Il-10 (improved post-war successor) operated by USSR, Czechoslovakia (as Avia B-33, ~1,200 built locally), Romania, Bulgaria, Hungary, China (Korean War period), Yugoslavia, Poland, North Korea (Korean War). Last Il-10 retirement was Romanian Air Force in 1962.
Civilian / preservation
No airworthy Il-2 in 2026. Roughly 9 static specimens survive worldwide: the Central Russian Air Force Museum (Monino, near Moscow — Il-2 single-seat and Il-2M3 two-seat), the Polish Aviation Museum (Kraków), Yad Vashem (Jerusalem — dedicated to memory of Soviet Jewish pilots), Russia's Naval Aviation collection (Il-2T torpedo variant), the Czech Air Force exhibit (Avia B-33), and a few others. Restoration to airworthy condition has not been attempted recently due to engine availability and structural-restoration complexity.

Frequently Asked Questions

How is the Il-2 the most-produced military aircraft ever?

Around 36,183 Il-2 airframes were built between 1941 and 1945 — more than any other single military aircraft type. For comparison: the Messerschmitt Bf 109 (most-produced fighter, ~33,984), the P-51 Mustang (~15,586), the Spitfire (~20,351 + Seafire). Soviet wartime industry mass-production of the Il-2 was an extraordinary feat — production rates exceeded 1,000 airframes per month at peak (1944), with airframe assembly lines running 24 hours per day at Voronezh and Kuybyshev. Total combined production with the post-war Il-10 successor exceeds 43,000.

What is the 'flying tank'?

An informal description applied to the Il-2 due to its heavily-armoured airframe. The aircraft is built around an armoured 'bathtub' of 4-12 mm steel and aluminium-alloy plate that forms the structural cockpit / engine / fuel-tank compartment. This armour was sufficient to deflect German 20mm cannon fire and most small-arms fire encountered in 1941-1942 ground operations. Pilots regularly returned home with airframes carrying hundreds of bullet holes that would have downed a conventional unarmoured aircraft. The 'flying tank' reputation was carefully cultivated by Soviet propaganda and was largely accurate — the Il-2's survivability against ground fire was the highest of any front-line WWII combat aircraft.

What did Stalin say about the Il-2?

The most-famous quote attributed to Stalin regarding the Il-2 is: "They are as essential to the Red Army as bread and water." The remark was made during a 1942 telegram to Sergey Ilyushin, urging accelerated production. Stalin's personal interest in the programme — and the resources marshalled to maintain Il-2 production through the 1941-1942 wartime evacuation of Soviet airframe industry from western Russia to the Urals and Siberia — was central to the Il-2's eventual production scale.

How does the Il-2 compare to the Stuka?

Different design philosophies. The Ju 87 Stuka was a dive-bomber for precision attacks against fixed targets; the Il-2 was a low-altitude ground-attack aircraft for close-support against battlefield and area targets (armour, infantry, transport, supply). The Il-2 had heavier armour and was more survivable against ground fire; the Stuka had higher precision but was extremely vulnerable to fighter interception. The Il-2 was used in much larger numbers (~36,000 vs Stuka's ~6,500). Both fulfilled essentially the same front-line mission — close-air support of ground forces — with very different design solutions.

What were PTAB submunitions?

PTAB (ПТАБ, Противотанковая Авиационная Бомба, "Anti-Tank Aviation Bomb") were small (1.5 kg or 2.5 kg) shaped-charge anti-armour submunitions deployed by the Il-2 in dispenser pods. Each Il-2M3 could carry 192 PTAB-2.5 submunitions. The submunitions were dropped in a scattered pattern from low altitude, achieving high probability of armour hits across a wide area. PTAB submunitions were used to devastating effect at Kursk (July 1943) against German Panther / Tiger / Tiger II tank formations. The PTAB approach — using many small precision submunitions rather than a few large bombs — was an early example of cluster-munition tactics.

How many Il-2s are still flying?

None airworthy in 2026. Roughly 9 static specimens survive globally. The Il-2's airframe and engine combination is no longer supported by parts manufacturing or maintenance infrastructure, and Russian / former-Eastern-Bloc Il-2 / Il-10 airframes have all been retired to static display rather than restored to airworthy condition. The most-recent Il-2 restoration project (Russian aircraft enthusiasts, partial restoration) has not produced an airworthy aircraft. Static airframes are concentrated in former-Soviet-bloc collections; the Smithsonian and other Western institutions do not currently include Il-2 specimens.
