Polikarpov I-153

The Polikarpov I-153 Chaika ( for "") was a Soviet developed in the late as an advanced refinement of the earlier I-15 series, incorporating retractable , a gull-wing upper configuration for improved , and a more powerful , making it one of the fastest and most maneuverable biplanes of its era and the last such design to see significant combat during . Designed primarily by Nikolai Polikarpov's team, including Aleksei Shcherbakov and Mikhail Gurevich, the I-153 originated from lessons learned in the , where the I-15 had faced Italian biplanes, prompting enhancements in speed, climb rate, and armament to counter emerging threats like Japan's Nakajima Ki-27. The prototype first flew in the summer of 1938, with production beginning in early 1939 and continuing until 1941, resulting in a total of 3,437 aircraft built across Soviet factories. In service with the (VVS), the I-153 debuted in combat during the 1939 (Nomonhan Incident) against Japanese forces in , where its superior maneuverability allowed it to hold its own against the lighter Ki-27 fighters, contributing to Soviet tactical successes in the region. It later saw action in the against (1939–1940), the German invasion of the in 1941, and limited operations in , where 93 examples were supplied to the in 1940 for use against Japanese bombers, though it proved vulnerable to advanced fighters like the . Captured or purchased variants served with the , achieving at least five aerial victories between 1939 and 1944. By 1943, the I-153 was largely relegated from front-line duties as monoplanes like the Yak-1 and La-5 took precedence, but it remained in secondary roles such as training and ground attack until the war's end. Key specifications included a single Shvetsov M-62 nine-cylinder radial engine producing 1,000 horsepower, enabling a maximum speed of 444 km/h (276 mph) at 4,600 meters and a service ceiling of 10,700 meters (35,100 ft). The aircraft measured 6.17 meters (20 ft 3 in) in length with a wingspan of 10 meters (32 ft 10 in), had an empty weight of approximately 1,452 kg (3,201 lb), and a max takeoff weight of 2,110 kg (4,652 lb), offering a combat radius of about 470 km (290 miles). Standard armament consisted of four synchronized 7.62 mm ShKAS machine guns in the fuselage, with some variants like the I-153P featuring twin 20 mm cannons or provisions for up to eight RS-82 rockets for ground support. Despite its obsolescence against modern monoplanes, the I-153's agility and reliability underscored the transitional nature of Soviet aviation in the early war years.

Background and development

Design origins

The Polikarpov I-153 originated as an evolutionary response to the shortcomings of earlier Soviet biplane fighters, particularly the I-15 and its improved variant, the I-15bis. The I-15, introduced in 1933, featured a distinctive gull-wing upper wing configuration but suffered from limited speed and vulnerability to more advanced monoplanes encountered in conflicts such as the Spanish Civil War. The I-15bis, entering service in 1937, addressed some armament and engine issues with a more powerful M-25V radial but retained fixed landing gear and straight wings, which continued to hinder top speeds around 379 km/h (236 mph) and overall maneuverability against faster adversaries like the German Messerschmitt Bf 109. In 1937, the Soviet Air Force (VVS) issued requirements for a modernized to bridge the gap toward dominance, emphasizing retractable to reduce drag and enhance speed, alongside superior aerobatic performance for dogfighting. This demand was fueled by lessons from international engagements, including the need for a versatile interceptor capable of operating at higher altitudes and maintaining the biplane's traditional agility. The Polikarpov design bureau, under , took on the project to refine the biplane formula rather than fully transitioning to monoplanes, with contributions from team members including Aleksei Shcherbakov and Mikhail Gurevich. The initial concept for the I-153, sketched in 1937, reintroduced the gull-wing upper wing from the original I-15 to improve pilot visibility over the nose and minimize aerodynamic interference with the , while integrating the mandated retractable gear for better performance. This design choice aimed to balance the biplane's inherent maneuverability with incremental speed gains, positioning the I-153 as a transitional fighter within the Polikarpov bureau's iterative approach to Soviet aerial requirements.

Prototypes and initial testing

The first prototype of the Polikarpov I-153, designated I-153 No. 1, was constructed in 1938 at Factory No. 1 in as an evolution from the earlier I-15 series of biplane fighters. The aircraft featured retractable landing gear and a gull-wing upper configuration to enhance speed while retaining the maneuverability of its predecessors. The of the first prototype occurred in August 1938, piloted by A. I. Zhukov. This initial sortie marked the beginning of flight evaluations for the design. Initial testing phases commenced in 1939, encompassing a range of assessments. Notably, spin recovery tests demonstrated the aircraft's excellence in this area, attributable to its configuration, which provided inherent and effective control authority during recovery maneuvers. Early evaluations also uncovered several issues requiring attention, including problems with the manual retraction mechanism, which was prone to jamming, and structural vibrations experienced at high speeds that affected overall handling. These findings were addressed during state acceptance trials conducted in the spring of , which ultimately validated the design's potential and resulted in an order for 10 pre-production to facilitate further refinement and evaluation.

Production and improvements

Production of the Polikarpov I-153 began in early at several Soviet factories, including Factory No. 1 in , Factory No. 21 in Gorky (), and Factory No. 39 in , following the successful state trials of prototypes that demonstrated the design's potential for mass manufacturing. By early 1941, when production shifted to more advanced fighters like the Yak-1 and LaGG-3, a total of 3,437 units had been completed across these facilities. The yearly output ramped up significantly to meet demands: approximately 1,011 in , 2,362 in 1940, and 64 in early 1941 before cessation. During the production run, several key improvements were implemented to enhance reliability and address operational feedback from initial deployments. Early models used the Cyclone-derived M-25V , but from 1939 onward, most transitioned to the more powerful and altitude-tolerant Shvetsov M-62 variant, which provided better climb rates and overall performance while improving engine durability in varied conditions. Structural refinements included reinforced wing elements to mitigate fatigue observed in high-stress maneuvers during testing and early use, ensuring the sesquiplane's gull-wing maintained its agility without compromising integrity. The rollout of I-153 production in 1938–1939 was hampered by the ongoing , which decimated experienced personnel in the Soviet aviation sector, including the arrest of designer himself from late 1937 until December 1938. This political repression, combined with factory relocations for strategic reasons amid rising tensions with and , led to inefficiencies, delays in tooling, and a temporary slowdown in output as new leadership and workers adapted to complex assembly lines. Despite these challenges, the program's scaling post-1939 helped restore momentum, leveraging the I-153's relatively straightforward mixed-construction design. Export considerations for the I-153 focused on allied needs in , with approximately 93–100 units supplied to the Chinese Nationalist forces to bolster defenses against Japanese aggression, incorporating minor adaptations for tropical operations. Similar provisions were evaluated for air units, given the type's proven effectiveness in the 1939 Battle of , though primary deliveries remained Soviet-operated rather than .

Design features

Airframe and aerodynamics

The Polikarpov I-153 employed a mixed construction airframe typical of late-1930s Soviet biplane fighters, featuring a welded steel-tube fuselage covered in fabric for lightness and ease of repair, while the wings utilized wooden spars and ribs also covered in fabric. This combination provided structural integrity under combat stresses while keeping overall weight low, at around 1,450 kg empty. The wing arrangement was a key aerodynamic feature, with the upper wing adopting a distinctive configuration—including a on the inboard sections for improved roll and pilot visibility over the nose—paired with a flat lower wing staggered slightly rearward. This setup, reminiscent of earlier Polikarpov designs like the I-15, optimized the aircraft's center of gravity and reduced wing interference in turns, contributing to its exceptional maneuverability at low speeds. To minimize , the I-153 incorporated retractable with inward-folding wheels and a fixed tailwheel, marking the first such implementation on a Soviet and yielding a notable performance boost over fixed-gear predecessors. The gear retraction reduced overall , enabling higher speeds—up to about 445 km/h—while maintaining the short takeoff and landing capabilities essential for forward operations. Despite these advances, the layout imposed inherent aerodynamic trade-offs: the I-153 excelled in tight turns and slow-speed dogfights due to its high , but interplane interference and strut drag limited its high-altitude efficiency and top-end velocity compared to emerging monoplanes. The aircraft's overall dimensions reflected this compact, agile design: a of 10 m (upper wing), of 6.17 m, and of 2.8 m.

Engine and propulsion

The Polikarpov I-153 was equipped with the Shvetsov M-62 nine-cylinder air-cooled as its primary powerplant, delivering 850 hp at 4,200 m and 1,000 hp at takeoff. This supercharged derivative of the earlier M-25, based on the American Wright Cyclone design, provided a significant power increase over the I-15's , enhancing overall agility for the fighter. Some production variants incorporated modifications such as the M-62F with to improve efficiency and reliability under combat conditions. The M-62's operational lifespan was limited to 60-80 hours between major overhauls, largely attributable to frequent failures in its two-speed , which imposed substantial maintenance demands on field units and contributed to high downtime rates during intensive operations. The engine drove a three-bladed variable- VISH-3 , designed to balance climb performance and maximum speed by allowing pitch adjustments in flight. Early fuel systems on the I-153 were susceptible to damage from enemy fire, prompting the adoption of self-sealing midway through to reduce the risk of catastrophic incidents. This propulsion configuration achieved a top speed of 444 km/h at 4,600 meters but was vulnerable to overheating during prolonged dives due to inadequate airflow over the cylinders. The retractable further aided efficiency by minimizing drag in level flight.

Armament and avionics

The Polikarpov I-153 was equipped with a standard fixed armament consisting of four synchronized 7.62 mm ShKAS machine guns, each carrying 500 rounds of ammunition and capable of firing at up to 1,800 rounds per minute. These guns were mounted in the upper , firing through the arc, allowing for effective concentration of fire during dogfights. For ground attack roles, the I-153 featured optional underwing bomb racks capable of carrying up to 200 kg of , typically in the form of four 50 kg FAB-50 bombs, or alternatively eight RS-82 unguided rockets mounted on external pylons. This configuration provided versatility in missions, though it compromised the aircraft's agility compared to its pure interceptor setup. Avionics on the I-153 were rudimentary by late standards, including a basic RSI-3 radio set for communication and a PBP-1 reflector gunsight for aiming the fixed weaponry. The aircraft lacked or advanced aids, relying instead on standard instrumentation such as an (ASI), , and turn-and-bank indicator to support operations. The ShKAS guns suffered from reliability issues, particularly frequent jamming in cold weather due to improper lubrication that congealed in low temperatures, requiring meticulous maintenance to mitigate stoppages during combat. Pilot protection was limited, featuring only a basic 8 mm armored plate behind the seat and partial shielding around the forward fuel tank to guard against small-arms fire and .

Variants

Standard variants

The standard production variants of the Polikarpov I-153 were primarily distinguished by engine choices and minor armament adjustments, with manufacturing focused on rapid output to meet needs from to 1941. The baseline model, designated I-153 M-62, featured the Shvetsov M-62 nine-cylinder rated at 1,000 hp for takeoff, a supercharged evolution of the earlier M-25 that enabled a top speed of approximately 445 km/h at 4,700 m. Approximately 3,000 units of this variant were produced between and 1940, emphasizing quantity over refinements, with standard armament of four synchronized 7.62 mm ShKAS machine guns in the upper cowling and retractable inherited from the core design. A specialized sub-variant, the I-153P (Pushechnyy, or "cannon-armed"), replaced the inner pair of machine guns with two 20 mm ShVAK autocannons in the engine cowling to enhance against armored targets. Only about eight were built in early 1940—three initial prototypes followed by five production examples—due to significant causing structural and aiming inaccuracies during firing. To address performance limitations at higher altitudes revealed in early testing, later production shifted to the uprated Shvetsov M-63 engine, delivering 1,100 hp at takeoff and 900 hp at altitude, which improved climb rate and operational ceiling without major changes. Around 409 I-153 M-63 aircraft were manufactured in 1941, representing a qualitative prioritized for frontline units facing modern threats. Export models for the Republic of China included adaptations with tropical air filters on the M-62 engine to suit operations in humid environments, with a total of 93 aircraft supplied between 1939 and 1941 for Nationalist forces. These followed the baseline configuration but incorporated minor modifications for regional logistics.

Experimental variants

The I-153DM was an experimental modification of the Polikarpov I-153 biplane fighter, developed in 1940 to enhance its top speed through the addition of auxiliary engines mounted under the wings. These gasoline-burning ramjets, designated DM-2 or more powerful DM-4 variants, provided a temporary boost, with the DM-2 increasing maximum speed by approximately 30 km/h and the DM-4 achieving up to 54 km/h during trials. The project underwent 74 test flights, demonstrating a peak speed of 440 km/h at 2,000 m in one evaluation, but was ultimately abandoned due to the ramjets' mechanical complexity, low overall efficiency, and minimal sustained performance benefits relative to the added weight and maintenance demands. In parallel, the I-153TK represented an effort to adapt the I-153 for high-altitude roles, featuring a twin TK-1 setup integrated with either the M-25V or M-62 and, in some prototypes, a pressurized for improved performance above 10,000 m. First flown in 1939 with tests continuing into 1940, the variant attained a top speed of 482 km/h at 10,300 m, but the modifications yielded only marginal gains in and climb rate, hampered by the inherent drag of the configuration. Although 26 examples were constructed—primarily for air defense evaluation—the project saw no further development by 1941, as the superchargers failed to overcome the aircraft's fundamental aerodynamic limitations. To address operational challenges in snowy conditions during the 1939-1940 against , engineers tested an I-153 variant equipped with retractable undercarriage, replacing the standard wheeled gear for better mobility on frozen airfields. Approximately 20 units underwent trials starting in late 1939, confirming the skis' utility for short takeoffs and landings in sub-zero temperatures, though handling was compromised at higher speeds due to increased drag. The configuration proved viable for limited winter deployments but was not pursued beyond prototyping, as the I-153's frontline role shifted and retractable wheels remained preferable for versatility. A 1941 proposal for an armored I-153 variant aimed to enhance pilot survivability by adding supplemental steel plating around the cockpit and fuel tanks, building on the standard model's basic 8 mm armored seat. This design was evaluated amid escalating ground-attack requirements but rejected outright due to significant weight penalties—estimated at over 200 kg—that reduced speed, climb rate, and maneuverability by 15-20%, rendering the biplane even less competitive against emerging monoplane fighters. Collectively, these experiments underscored the I-153's growing obsolescence by , as modifications could not bridge the performance gap to newer monoplanes like the Yak-1 or LaGG-3, leading Soviet designers to redirect resources away from biplane enhancements.

Operational history

Pre-World War II conflicts

The Polikarpov I-153 made its combat debut during the in 1939, a major Soviet-Japanese border conflict along the Mongolian-Manchurian frontier. Approximately 70 I-153s were deployed against Japanese (Army Type 97 Fighter) aircraft, where the biplane's agile design and four synchronized 7.62 mm ShKAS machine guns proved superior in close-range dogfights. Soviet pilots leveraged the I-153's retractable to simulate the slower I-15 and lure enemies into traps, followed by aggressive vertical maneuvers such as loops and zooms to out-turn the Ki-27s. Team formations, often in pairs or flights of three to four aircraft, allowed for coordinated attacks that protected vulnerable members while maximizing firepower. These tactics contributed to Soviet air superiority in the theater, with the I-153 suffering 23 losses, primarily to enemy fighters but also due to operational accidents in harsh terrain. During the Soviet-Finnish of 1939-1940, I-153s were committed to operations against , focusing on low-altitude and missions to support infantry advances through forested terrain. The aircraft excelled in these ground-attack roles, using its maneuverability for precise dives and its armament for suppressing anti-aircraft positions, but it struggled against faster Finnish monoplanes like the Brewster B-239. The type suffered heavy losses, mostly to ground fire and fighter intercepts, revealing vulnerabilities in speed and armor during prolonged engagements. Finnish forces captured eight intact examples after forced landings, later employing them operationally. Combat experience from both conflicts highlighted critical design flaws, particularly the I-153's fuel system, where the unprotected tank forward of the cockpit lacked a firewall, allowing hits to ignite rapid fires that engulfed the pilot via drafts from the wheel wells. This vulnerability led to severe burn injuries and high abandonment rates in damaged aircraft. Numerous improvements were proposed but deemed too radical to implement during production. These lessons validated the biplane's role in peripheral wars but emphasized the need for monoplane escorts in future operations.

World War II service

The Polikarpov I-153 served as a mainstay for the (VVS) at the outset of in June 1941, with around 1,500 aircraft assigned to frontline fighter regiments in the western districts. These biplanes formed a significant portion of the VVS's initial defense against the , engaging in intense air battles despite their speed disadvantage against the Messerschmitt Bf 109. Soviet pilots, including those flying I-153s, claimed over 800 enemy aircraft destroyed by early July 1941, particularly in actions by units like the 122nd Fighter Aviation Regiment, which downed 35 German planes on the first day alone while losing only four of their own. However, the type suffered heavy attrition, with hundreds of I-153s lost in the first two weeks—many to superior German fighters and others destroyed on the ground during surprise attacks—highlighting the biplane's vulnerability in high-altitude intercepts. During the defense of from late to , surviving I-153 units, numbering about 94 in the 6th Fighter Air Corps, shifted toward low-level night harassment of German troop concentrations and protection of supply convoys. The 's agility at low altitudes allowed it to contribute to air superiority efforts in the Moscow region, with pilots from regiments like the 120th IAP claiming significant engagements against bombers and escorts. By December 1941, intense operations had reduced serviceable I-153s in key units to as few as 11, as the type was increasingly supplemented by more modern monoplanes. In the Stalingrad and campaigns of 1942–1943, the I-153 transitioned primarily to roles within units like the 8th Air Army, where it was fitted with RS-82 rockets and small bombs for strikes against German armor and infantry. The biplane proved effective in low-level attacks on assault guns such as the StuG III, with pilots like Nikolai Loginov of the 267th IAP conducting 42 sorties in the region between and 1942, destroying 54 vehicles, three anti-aircraft guns, and up to 200 enemy personnel. By mid-1943, however, the I-153's obsolescence against advanced fighters like the Fw 190 led to its withdrawal from air superiority duties, with only a small number remaining operational at the front. Overall, the I-153 incurred approximately 1,200 losses to enemy action and 800 to accidents or operational causes during , underscoring its heavy commitment in the VVS's early defensive struggles. In the Finnish from 1941 to 1944, the operated 21 captured I-153s—11 seized during the and additional ones acquired via —for patrol, reconnaissance, and combat duties over the . Finnish pilots achieved at least five confirmed aerial victories with the type, including against Soviet I-16s and P-39 Airacobras, primarily with LeLv 6 and LeLv 30 before its phase-out in 1944; seven aircraft were lost, one in combat and six to accidents.

Post-war operations

Following the conclusion of , the Polikarpov I-153 continued in limited secondary roles before being fully phased out across its operators. In the , the type had already been largely withdrawn from frontline service by 1943, primarily in the where some units employed them until 1945. These survivors were relegated to non-combat duties amid the rapid introduction of superior monoplanes like the Yak-9 and La-5, rendering the obsolete in the face of advancing jet technology. The Chinese Nationalist Air Force, which had received 93 I-153s from Soviet supplies in early 1940, maintained a number of the fighters into the immediate post-war years. Although exact operational details during the (1946–1949) are limited, the aircraft saw use alongside more modern U.S.-provided types such as the P-51 Mustang, before being fully supplanted as Nationalist forces prioritized re-equipment with advanced monoplanes. No significant combat employment of the I-153 occurred after , with any lingering examples confined to instructional or reserve capacities where feasible. In contemporary evaluations, the is appreciated for its exceptional aerobatic capabilities and historical maneuverability , though critiqued for inherent vulnerabilities in the emerging jet-dominated ; several restored airworthy specimens persist for demonstration flights at airshows today.

Operators

Primary operators

The Soviet Air Force (VVS) was the primary operator of the Polikarpov I-153, receiving the vast majority of the approximately 3,437 aircraft produced between 1939 and 1941. By , around 1,300 I-153s were in service across the western districts, equipping numerous interceptor aviation regiments (IAPs), such as the 122nd, 127th, and 129th IAPs, which flew the type extensively in frontline roles. The Republic of China Air Force imported 93 I-153s from the Soviet Union between 1939 and 1941 as part of broader Lend-Lease-style aid during the Second Sino-Japanese War, integrating them into fighter groups for combat against Japanese forces. The Mongolian People's Revolutionary Army Air Force received over 50 I-153s starting in 1939, primarily for training purposes, with the aircraft remaining in service through 1952; these supplemented Soviet deployments in the region during the Battles of Khalkhin Gol.

Captured and other uses

The captured eight I-153s during the (1939–1940) through forced landings and three more during the (1941–1944), for a total of 11 captured ; an additional nine were purchased from between November 1942 and August 1943, bringing the total operated to 20. These were rearmed with four 7.70 mm Browning M/39 machine guns and equipped with the BBC AAK-1 gunsight, serving primarily with LeLv 30 (1942–1944) and TLeLv 16 (1944) for reconnaissance, patrols, and limited combat roles until 1944. pilots flying I-153s achieved five confirmed aerial victories against Soviet , including one SB-2 , two I-16 fighters, one I-153, and one P-39 Airacobra, alongside the destruction of one Soviet motorboat. Captured I-153s entered limited service with the , where they were designated "Chaika" after the Russian nickname and tested at the Rechlin experimental center starting in 1941 to evaluate Soviet fighter performance. Examples were also employed for training at facilities like Jagdfliegervorschule 3 in Wien-Schwechat and briefly with Luftlandegeschwader 1 on the Eastern Front in 1942, though no combat victories are recorded and operational integration remained minimal.

Surviving aircraft

Museum displays

The Polikarpov I-153 is preserved in limited numbers as static exhibits in museums, reflecting its role in early air combat. These displays highlight the aircraft's sesquiplane design and historical provenance, often from captured or recovered examples. A prominent static example is at the in , . Captured by German forces during the Eastern Front campaign, it was exhibited as a war trophy at Nanterre-La Folie during the Nazi occupation of . Following , the aircraft entered the museum's collection in the early 1950s, where it has been preserved as one of the few original survivors. Constructed primarily of wood and fabric, the I-153 is highly susceptible to and fluctuations, leading to ongoing work at the museum's Dugny workshops since the . The bears visible damage from gunfire, and the avoided postwar scrapping due to its perishable materials. As of 2023, it is in storage pending completion of conservation, representing Soviet biplane fighter technology from the late 1930s. Recent archaeological efforts have uncovered additional I-153 components, contributing to preservation. In the early , multiple wrecks were salvaged from northern Russian sites, including swamps near , enabling restorations that bolster museum interpretations worldwide, though no major new static displays have emerged since.

Airworthy examples

As of 2025, three Polikarpov I-153 Chaika biplanes remain airworthy, representing a rare preservation of this late-1930s Soviet design. Three examples were restored to flying condition in the late 1990s by the Alpine Fighter Collection in , using airframes recovered from wrecks in . One of these, serial number 6316 (ZK-JKN / N153RP), is now at the in , , where its airworthiness status is uncertain as of 2023 but reported as airworthy in some 2025 sources. Powered by a Shvetsov M-62 producing 1,000 horsepower, it highlights recovery efforts from Soviet service. Another, serial number 6326 (formerly ZK-JKM), is airworthy in at the Fundació Parc Aeronàutic de as EC-LPC, having been relocated from . In , an I-153 underwent restoration and is airworthy, regularly performing at major events like the MAKS International Aviation and Space Salon as of 2021, demonstrating the type's aerobatic capabilities to honor its legacy. Its airworthiness supports educational heritage flights, often paired with other preserved Soviet aircraft. Preserving these aircraft demands rigorous annual inspections, exacerbated by the limited availability of M-62 engines and compatible spares, many of which must be fabricated or sourced from global wrecks. Owners often incorporate modern safety enhancements, such as GPS navigation and updated , to ensure safe operations while retaining historical authenticity.

Specifications

General characteristics

The Polikarpov I-153 was a single-engine, single-seat sesquiplane fighter designed for agility in aerial combat. It accommodated a crew of one pilot. The aircraft measured 6.17 m in length, with a wingspan of 10.00 m (upper wing), a height of 2.80 m, and a wing area of 22.14 m². The empty weight was 1,452 kg, while the gross weight reached 2,110 kg. Power was provided by a single Shvetsov M-62 nine-cylinder air-cooled radial piston engine rated at 1,000 hp (746 kW) for takeoff. Internal fuel capacity totaled 310 L. The supported up to 200 kg of external stores. A total of 3,437 aircraft were produced between 1939 and 1940. While the standard model used the M-62 engine, variants such as the I-153P incorporated different armament configurations or powerplants like the M-63 for enhanced performance.

Performance

The Polikarpov I-153 equipped with the Shvetsov M-62 radial engine exhibited solid performance characteristics for a biplane fighter, particularly in low-altitude operations where its maneuverability shone. Maximum speed reached 444 km/h (238 kn) at 4,600 m, while cruise speed was approximately 300 km/h, allowing for effective tactical employment in close-range engagements. Range was limited to 470 km (290 mi) at under normal conditions, though ferry range extended to 825 km with the addition of drop tanks, supporting logistical transfers without refueling. The service ceiling stood at 10,700 m (35,100 ft), with a of 14.9 m/s enabling rapid ascents to intercept low-flying threats. measured 95 /m², contributing to its agile handling, while the power-to-mass ratio of 0.35 kW/ provided balanced for its era. Performance varied significantly with altitude; at , top speed dropped to around 366 km/h, and above 5,000 m, the aircraft's velocity declined further, limiting its effectiveness in high-altitude intercepts. Compared to its predecessor, the I-16, the I-153 offered superior low-speed maneuverability and climb rates, enhancing its dogfighting prowess below 5,000 m, but it remained outclassed by contemporaries like the at higher elevations due to inferior speed and engine efficiency.

Armament

The Polikarpov I-153 was equipped with four 7.62 mm ShKAS machine guns as its primary fixed forward-firing armament, with four synchronized guns mounted in the upper . These weapons were supplied with a total of 2,600 rounds of ammunition, typically including armor-piercing incendiary () and incendiary rounds optimized for anti-aircraft engagements. For ground attack roles, the I-153 featured underwing hardpoints capable of carrying up to four 50 kg bombs or two 100 kg bombs. It could also be fitted with up to eight RS-82 unguided rockets mounted beneath the wings. The standard production model did not incorporate cannons, relying instead on the high of the ShKAS guns—up to 1,800 rounds per minute each—for offensive capability. Aiming was facilitated by a fixed optical in the .
