The IAR 80 was a Romanian World War II low-wing monoplane, all-metal monocoque fighter and ground-attack aircraft. When it first flew, in 1939, it was comparable to contemporary designs being deployed by the airforces of the most advanced military powers such as the Hawker Hurricane and Bf 109E.[2] Production problems and lack of available armament delayed entry of the IAR 80 into service until 1941. It remained in frontline use until the end of the war.[3]

Development

IAR-80 undergoing maintenance

In order to ensure that the Royal Romanian Air Force (ARR) could continue to be supplied with aircraft in time of war, the government subsidized the creation of three major aircraft manufacturers in the 1920s and 1930s. The first was Societatea Pentru Exploatări Tehnice (SET) which was formed in Bucharest in 1923. Next came Industria Aeronautică Română (IAR) which set up shop in Brașov in 1925. Finally there was Întreprinderea de Construcții Aeronautice Românești (ICAR), which was founded in Bucharest in 1932.

In 1930 the Romanian government issued specifications for a new fighter. Although the government was not anticipating bids from its own aircraft industry, IAR produced several prototypes in response to the tender.

The contract was eventually won by the Polish PZL P.11. The ARR purchased 50 of a modified version called the P.11b, all of which were delivered in 1934. A second contest was also fought between the newer IAR 14 and PZL P.24 designs, and once again the PZL design won a contract for another 50 aircraft.

Although IAR's own designs had not entered production, they nevertheless won the contracts to build PZL fighters and Gnome-Rhône 14K engines under license. As a result of these and other licence contracts the company had enough money to fund a design studio even if its designs never went into production.

Despite losing to PZL, an IAR design team led by Ion Grosu continued work on fighter designs. He was convinced that the low-wing design of the IAR 24 represented a better design than the PZL gull-wing design, which was often referred to as the "Polish wing". Once again the team studied the new PZL fighter looking to incorporate its best features into a new aircraft, and the result was the IAR 80.

Design

IAR 80 side view
  • Description: Low-wing monoplane fighter with conventional control surface layout.
  • Fuselage: The fuselage was circular in cross-section, turning to egg-shaped behind the cockpit where it incorporated a ridge-back. The rear fuselage layout, and the engine cowling were based on the Polish PZL P.24.[4]
  • Wings: The wings were tapered with rounded tips, the trailing edge angled very slightly forwards. Small flaps ran from the fuselage to a point about 1/3 along the span, where the ailerons started and extended out to the rounded wingtips.
  • Other details: A bubble canopy was fitted, sliding to the rear to open, providing excellent visibility except over the nose due to its rearward position. A conventional tailwheel landing gear was used, with the main gear wide-set and retracting inward, with a non-retractable tail skid.

The semi-monocoque tail was copied directly from the PZL P.24. The fuselage from the engine back to the cockpit was new, consisting of a welded steel tube frame covered with duralumin sheeting. The wings were mounted low and were of the same design as those used on the early IAR 24, which had competed with the PZL P.24.

According to an urban legend, the wing profile was copied from the Italian Savoia-Marchetti SM.79 bomber, in service with the ARR at the time, as the design team lacked the time for wing section studies. As a result, the profile was less favorable for higher speeds, but gave the aircraft more maneuverability. This is false as the contract for the SM.79B licence was signed on October 1, 1938, roughly one year after the IAR 80 prototype was completed.[5]

The cockpit's interior, instruments, and gunsight were imported from foreign suppliers. This effort to aggregate a fighter from various sources was a result of the last-minute demands for a frontline fighter. The initial IAR 80s were fitted with iron sights. Starting with the 21st aircraft, these were replaced by Goerz GM2 reflector sights which were manufactured under license by Întreprinderea Optică Română as the "Telereflex" gunsights.[6]

A Luftwaffe major who tested it in March 1941 had this to say about the IAR 80:

Further development

IAR realized that the Mistral Major was at the limits of its development potential even by the middle of 1941, when the 1000A model reached the same ultimate output as the original Gnome-Rhône engines. An ongoing program to fit the IAR 80 with a more powerful engine had been in the works for most of the design's lifetime, but this proved to be a fruitless endeavor.

The most obvious choice for a new engine would have been the BMW 801 used in the Focke-Wulf Fw 190. This engine produced a full 600 hp (450 kW) more power, and although it was heavier, it was of roughly the same size as the IAR K14. IAR engineers estimated that a BMW powered IAR 80 would have a maximum speed of at least 600 km/h (370 mph). But the Germans were unable to supply the engine as every example coming off the line was needed for installation in a German airframe. Licensed production was likewise out of the question, the engine production was in the midst of being ramped and the demand was so great that not even one set of jigs could be spared.

In the spring of 1941, IAR 80 no. 13 was fitted with a Daimler-Benz DB 601Aa engine borrowed from a Bf 109E. A flight test was carried out on 21 April 1941, but due to the strong vibrations, the pilot barely managed to bring it to the ground. Development was abandoned after this test flight, and was never flown again. Other tests were carried out with a 1,475 PS (1,085 kW; 1,455 hp) Daimler-Benz DB 605A fitted to IAR 81C no. 326 in the summer of 1943. According to the test reports, the aircraft's performance was greatly improved, however due to difficulties in producing the engine and the Germans not having engines for sale, the project did not materialize.[10]

Operational history

"Hero shot" of an IAR-80 pilot with his aircraft

When Operation Barbarossa started, the IAR 80 equipped Esc. 41, 59 and 60 of Grupul 8 Vânătoare (8th Fighter Group), part of the Gruparea Aerienă de Luptă (GAL), that were tasked to support the Romanian 3rd and 4th Armies deployed at the southern flank of the Eastern Front.[11] 8th Group was the only unit assigned a pure fighter role, while 5th and 7th Groups, equipped with German aircraft (Heinkel He 112s and Messerschmitt Bf 109s) were employed primarily as fighter-bombers and bomber escorts.[12]

On 22 June 1941, during the first day of the offensive, the IAR 80 patrols had their baptism of fire, achieving a single aerial victory (claimed by Sublocotenent aviator Ioan Mihăilescu of Esc 60 Vânătoare, a future ace) during four separate air combats. However, at least four IARs force landed with battle damage, while another two suffered engine trouble.[13] By the end of 1941, 20 IAR 80/81s had been lost in combat or accidents.[14] During 1942 the Romanian aviation industry reached its highest output so that the Royal Romanian Air Force could be re-equipped as follows: Esc. 47, 48 and 52 (Grupul 9 Vânătoare), Esc. 43, 44 and 50 (Grupul 3 Vânătoare) and Esc. 41, 42 and 60 (Grupul 8 Vânătoare) received the new IAR 80A. Esc. 53 also replaced its Hurricanes with the IAR 80A, while Grupul 6 Bopi (Bombardament în Picaj - Dive Bombing) re-equipped with the IAR 81.[15]

In June 1942, the operational IAR fighter forces on the eastern front, combined into the Flotilla 2 Vânătoare consisted of Grupul 8 Vânătoare, commanded by Cdr. Lt Col E. Pîrvulescu, and included Escadrila 41, Escadrila 42 and Escadrila 60 with 12 IAR 80As each. During the Battle of Stalingrad, on 12 September, the 8th Fighter Group's IAR 80Bs (along with the 7th Fighter Group's Bf 109s) claimed to have shot down seven Yaks but they lost two IARs.[16] Grupul 8 moved at the end of September, to Karpovka, joining Grupul 7, equipped with Bf 109s.[17] On 12 and 13 December, Grupul 6 used its IAR 81s to support the German counterattack by the Panzergruppe Hoth of the Heeresgruppe Don, from Kotelnikovo towards Stalingrad.[18]

In the summer of 1943 the ARR's IAR 80s were transferred to Romania for air defense duties, where they were used in combat against the United States Air Force. USAAF attacks were directed at the oil refineries installation around Ploiești, in particular. On 1 August 1943 the IAR 80 faced the Consolidated B-24 Liberator heavy bomber for the first time. There were 178 B-24s from 9th USAAF, part of Operation Tidal Wave. The IAR 80Bs of Escadrila 61 and 62 of Grupul 6 Vânătoare, as well as IAR 80Cs from the newly formed Escadrila 45 of Grupul 4 Vânătoare,[19] together with the Bf 109Gs from Esc. 53 and Bf 110s from the Romanian night fighter squadron, dived on the low-flying, four-engined bombers, belonging to five USAAF bomber groups (the 44th, 93rd, 98th, 376th and 389th). The Americans lost – in combat or on the way back – 51 bombers. Only 89 reached their bases, of which only 31 were serviceable for a mission the next day. The Romanian pilots claimed 25 certain and probable victories for just two losses,[15] one IAR 80B and one Bf 110C. According to Romanian statistics, IARs and Messerschmitts were confirmed as having shot down ten B-24s, with two probables.[20]

On 21 April 1944, IAR 81Cs of the 1st, 2nd, and 6th Fighter Groups took off to intercept B-17 and B-24 bombers which were targeting the Bucharest marshalling yard. While attacking the bombers, the Romanian fighters were engaged at high altitude by the escorting P-51 Mustangs of the 31st Fighter Group. In the aftermath of the air battle, the ARR lost 14 IAR 80s and 11 pilots were killed, while the Americans reported 10 aircraft lost.[21]

Abandoned IAR 81C no. 411 being inspected by Soviets[22]

On 10 June 1944, IAR 80s took part in a major air battle when the USAAF attacked Ploiești with 38 P-38 Lightnings of the 82nd Fighter Group carrying one bomb each, escorted by 39 Lightnings of the 1st and 82 FGs.[23] The IAR 81Cs from Grupul 6, as well as the German fighters from I./JG 53 and 2./JG 77, intercepted the large American formation. Romanian pilot Dan Vizanty, commander of Grupul 6, recalled later:

"Our Lightning attack came as a complete surprise to the Americans. Our attack was so quick that not one of the 100 (sic) American aircraft managed to fire a single shot at our aircraft parked on the ground. Everything happened between ground level and about 2,000 meters (6,600 feet), and was total confusion. I was excited and proud of my "mills", the IAR 80s, which, thanks to their extraordinary agility, remained victorious in the air. I saw their crazy dives, quick rolls, reverse turns and inverted flying, always with just brief burst of fire to save ammunition. It was an incredible sight, but also a drama for the Lightning pilots, who, at this low altitude, were inferior to the ever-present, nimble IAR 80s".

The USAAF lost 22 P-38s on that day,[24] of which 9 were shot down by the IARs.[25] The Romanians claimed 24 victories, suffering three losses.[26] The Americans claimed 11 victories.[23]

IAR 80 during the winter on the eastern front

The American account of this battle conflicts significantly with the Romanian one. Fighter pilot Herbert "Stub" Hatch, who took part in the dogfight, wrote that his flight of 16 P-38s, the 71st Fighter Squadron, was challenged by a large formation of Romanian IAR 81C fighters that he misidentified as Focke-Wulf Fw 190s.[24] According to Hatch, the fight took place at and below 300 feet (100 m) in a narrow valley.[24] Hatch saw two IAR 81Cs hit the ground after taking fire from his guns, and his fellow pilots confirmed three more kills from his guns. Three of his victories were confirmed by gun camera, while the other two by his wingman, making Hatch an ace in a day.[27] However, the outnumbered 71st Fighter Squadron lost nine aircraft. The Americans never again repeated the P-38 dive-bombing mission profile over Romania.[28] But during 1944 USAAF aircraft appeared over Romania in more significant numbers. Many air combats occurred and by the time of their last encounter with the USAAF on 3 July 1944, pilots of Grupul 6 vânătoare had submitted 87 confirmed and ten unconfirmed claims.[29] Casualties among the Romanian fighter pilots quickly mounted too. The three IAR 80/81 groups (the 1st, 2nd and 6th) in a period of less than four months – known as the "American Campaign" – had at least 32 IAR pilots killed in action, including 11 aces. These losses exceeded the number of casualties suffered in the previous two and a half years of fighting against the Soviets.[30] Because of heavy losses, all IAR 80/81 units were withdrawn from combat against Americans in July 1944 and IAR pilots started to convert to the more modern Bf 109G-6s.[29]

Surviving aircraft

After the Soviet occupation of Romania, all remaining IAR 80s were replaced with Soviet designs and scrapped. No complete original examples are known to survive. A static replica of the IAR 80 rebuilt post war after the fall of Communism and painted in its 1941–1944 original colors was shown at the Mihail Kogălniceanu airshow, near Constanța. The IAR 80 replica can be seen at the Romanian National Military Museum in Bucharest.[31][32] Another IAR 80 static replica can be found at the National Aviation Museum at the defunct Pipera Airport in Bucharest, which was rebuilt from IAR 80DC two-seat trainer parts. As of 2017 few attempts have been initiated to produce an airworthy accurate replica of the IAR 80 based on existing factory documentation and recovered components. A flying IAR 80 is still to be seen.[33] Since 2020, the Fly Again volunteer association is currently developing an airworthy replica of the IAR 80 which will be named IAR 80FA (Fly Again) and will carry the board number 451, where the original production left off.[34]

In fiction

The IAR 80 appears in the historical fiction book Eighty Flights of a Not-So-Much-Of-A-Fighter-Pilot by Cătălin Pogaci.
