The '''Seversky P-35''' is an American [[fighter aircraft]] built by the [[Republic Aviation|Seversky Aircraft Company]] in the late 1930s. A contemporary of the [[Hawker Hurricane]] and [[Messerschmitt Bf 109]], the P-35 was the first single-seat fighter in [[United States Army Air Corps]] to feature [[Aluminum|all-metal]] construction, [[Landing gear|retractable landing gear]], and an enclosed [[cockpit]].

==Design and development==
The origins of the P-35 can be traced back to the [[Seversky SEV-3]] three-seat [[amphibian aircraft|amphibian]], designed by [[Alexander Kartveli]], Seversky's chief designer and Seversky's first aircraft. The SEV-3 first flew in June 1933 and was developed into the Seversky BT-8 basic trainer, 30 of which were ordered by the [[United States Army Air Corps]] (USAAC) in 1935.<ref name="AE 10 p8-9">Green and Swanborough 1979, pp. 8–9.</ref> This proved grossly underpowered and was quickly replaced by the [[North American BT-9]].<ref name="Davies p4">Davies 1994, p. 4.</ref>

The second prototype SEV-3 was completed as a two-seat fighter derivative, the SEV-2XP. It was powered by a 735&nbsp;hp (548&nbsp;kW) [[Wright R-1820]] radial engine, had fixed landing gear in aerodynamic spats<ref name="AE 10 p9-10">Green and Swanborough 1979, pp. 9–10.</ref><ref name="Angel p384">Angelucci and Bowers 1987, p. 384.</ref> and was armed with one .50&nbsp;in (12.7&nbsp;mm) and one .30&nbsp;in (7.62&nbsp;mm) forward-firing machine guns plus an additional .30&nbsp;in (7.62&nbsp;mm) gun for rear defence.

When the [[USAAC]] announced a competition for a new single-seat fighter in 1935, Seversky sent the SEV-2XP, confident it would win despite being a two-seater. However, the aircraft was damaged on 18 June 1935 during its transit to the fly-offs at [[Wright Field]]. To compete with the [[Curtiss P-36|Curtiss Model 75]], a single-seat aircraft with retractable undercarriage, Seversky rebuilt the aircraft into the single seat SEV-1XP, replacing the SEV-2XP's fixed landing gear with a retractable undercarriage where the mainwheels retracted backwards into the wing, and an 850&nbsp;hp (634&nbsp;kW) R-1820-G5 replacing the -F3 of the SEV-2XP. The SEV-1XP was delivered to Wright Field on 15 August for evaluation, which was generally successful, although the Cyclone failed to deliver its rated power and the SEV-1XP only reached 289&nbsp;mph (465&nbsp;km/h) rather than the 300&nbsp;mph (483&nbsp;km/h) predicted by Seversky.<ref name="AE 10 p10">Green and Swanborough 1979, p. 10.</ref>

Protests from Curtiss led to the formal flyoff between the fighters to be delayed until April 1936. The delay was used by both Seversky and Curtiss to improve their aircraft, while allowing additional fighters from [[Vought]] (the [[Vought V-141]]) and [[Consolidated Aircraft|Consolidated]] with a single seat version of the [[Consolidated P-30|PB-2]]. The SEV-1XP was re-engined again, with a two-row [[Pratt & Whitney R-1830]]-9 "Twin Wasp" replacing the Cyclone and a modified [[vertical stabilizer]] fitted, becoming the SEV-7.<ref name="Angel p384"/><ref name="AE 10 p10-1">Green and Swanborough 1979, pp. 10–11.</ref>

The P&W also failed to deliver its rated power as it put out only {{cvt|738|hp|kW}},<ref>{{Cite web |title=Seversky P-35 |url=https://www.aircraftinformation.info/JB_AIF/usaf_fighters/p35_1.html |access-date=2025-02-18 |website=www.aircraftinformation.info}}</ref> and top speed was again well below 300&nbsp;mph. While more expensive than the Curtiss and Vought designs, the Seversky was a clear winner of the Air Corps' competition, with an order for 77 P-35 fighters and spare parts equivalent to eight airplanes being placed on 16 June 1936 at a cost of $1,636,250.<ref>Editors, "Contract Awarded For Pursuit Airplanes", ''Air Corps News Letter'', Information Division, Air Corps, Munitions Building, Washington, D.C., 1 July 1936, Volume XIX, Number 13, page 14.</ref><ref>{{cite web|url=https://www.scribd.com/document/76986615/Air-Force-News-Jul-Dec-1936|title=Air Force News ~ Jul-Dec 1936 - Military - Aviation|website=Scribd}}</ref>  Modifications from SEV-1XP to production P-35 standard included partial instead of complete mainwheel fairings and seven degrees of [[dihedral (aircraft)|dihedral]] to the outer wing panels.<ref name="AE 10 p11">Green and Swanborough 1979, p. 11.</ref>

The first production P-35 was delivered to the USAAC in May 1937, preceded by a company owned pre-production aircraft and demonstrator, the AP-1.<ref name="AE 10 p11"/> Only 76 P-35s were built, delivery being completed in August 1938, with the 77th aircraft finished as the prototype [[Seversky XP-41|XP-41]].<ref name="AE 10 p15-6">Green and Swanborough 1979, pp. 15–16.</ref> When it wanted further fighters in 1937, the Air Corps, who were unhappy with both the slow delivery of the P-35, and sale of 2PA two-seat aircraft to the Japanese Navy, ordered 210 [[Curtiss P-36]]s.<ref name="Angel p386">Angelucci and Bowers 1987, p. 386.</ref>

Also in 1937, a P-35 with naval equipment was supplied to the [[United States Navy]] for a design competition to replace the Navy's biplane fighters with an all-metal [[monoplane]]. Contrary to usual Navy practice, the single test aircraft was not assigned a formal Navy serial number nor a type designation; it was instead operated under civil [[aircraft registration]] as ''NX1254'' and called the '''NF-1''', a company designation standing for "Naval Fighter One". The prototype competed against the [[Brewster F2A]] and [[Grumman F4F]], but was found unsatisfactory, with the F2A being ordered into production.<ref name=BaugherNF-1>{{cite web|last=Baugher|first=Joe|title=Seversky NF-1|url=http://www.joebaugher.com/usaf_fighters/p35_3.html|website=joebaugher.com|date=25 December 1999 <!-- Merry Christmas--> |access-date=21 October 2021}}</ref>{{efn|The original Grumman XF4F-1 was a [[biplane]] like preceding Grumman fighters, and it lost the competition because its projected performance was inferior to the monoplanes.

Seversky continued to develop the design with the hope of selling more aircraft both to the Air Corps and to civil and export customers. It modified the prototype SEV-1XP as a single seat racer, the S-1 entering it into the 1937 [[Bendix Trophy]], where it finished in fourth place. The competition was won by the S-2 ([[aircraft registration|registration number]] NR70Y), a similar aircraft built for Frank Fuller of the Fuller Paint Company.<ref name="AE 10 p13">Green and Swanborough 1979, p. 13.</ref> S-2 also won the Bendix Trophy in 1939<ref>[http://www.airracinghistory.freeola.com/Between%20the%20wars(2).htm "Bendix Trophy."] ''Air Racing History''.

Another civil aircraft was the DS, (or Doolittle Special), a single seater for [[Jimmy Doolittle|James Doolittle]], employed at the time by the [[Shell Oil Company]], while the AP-7 was another racer, powered by a 1,200&nbsp;hp (895&nbsp;kW) R-1830 engine and used by [[Jacqueline Cochran]] to win the 1938 Bendix Trophy race and to set a women's air speed record.<ref name="AE 10 p14-5">Green and Swanborough 1979, pp. 14–15.</ref><ref name="Davies p43">Davies 1994, p. 43.</ref> Seversky entered two aircraft based on the P-35 in a 1938 competition for a new fighter for the Air Corps. One was the XP-41 (which had the company designation AP-4D, which was a P-35 with a 1,200&nbsp;hp (895&nbsp;kW) R-1830-9 engine fitted with a two-stage [[supercharger]]) and the AP-4, which had a turbo-supercharger mounted in the belly of a deeper fuselage. The Air Corps preferred the AP-4D, which was ordered into production as the [[Republic P-43 Lancer|P-43 Lancer]].<ref name="AE 10 p15-6"/><ref name="Angel p387-8">Angelucci and Bowers 1987, pp. 387–388.</ref><ref name="Davies p45">Davies 1994, p. 45.</ref>

Aiming to increase sales, [[Alexander P. de Seversky]] personally took a demonstrator on a tour of Europe in early 1939. As a result of this demonstration, Sweden ordered 15 EP-106 fighters on 29 June 1939,<ref name="AE 10 p16">Green and Swanborough 1979, p. 16.</ref> a development of the P-35 powered by a 1,050&nbsp;hp (783&nbsp;kW) R-1830-45, which improved performance by over 25&nbsp;mph (40&nbsp;km/h) and armed with two 7.9&nbsp;mm (.311&nbsp;in) machine guns in the [[Cowling|cowl]] and two 13.2&nbsp;mm (.52&nbsp;in) machine guns in the wings.<ref name="Fitzsimmons p. 905">Fitzsimmons 1981, p. 905.</ref> A second order for 45 EP-106s was placed on 11 October 1939,<ref name="AE 10 p16"/> with a third order for 60 aircraft, placed on 6 January 1940, although by this time Seversky had been thrown out of the company bearing his name by the board of directors, with the company renaming itself [[Republic Aviation]].<ref name="Davies p21-2">Davies 1994, pp. 21–22.</ref> The [[Swedish Air Force]] designated them J 9.<ref name="AE 10 p17">Green and Swanborough 1979, p. 17.</ref>

===Two-seat versions===

{{main|Seversky A8V}}
Seversky also built a two-seater, the '''2PA'''. Evolved in parallel with the P-35, the 2PA was a two-seat fighter and fighter-bomber with a fundamentally similar airframe and offered with either a similar undercarriage to that of the single-seater as the 2PA-L (Land) or with an amphibious float undercarriage as the 2PA-A (Amphibian). Dubbed "Convoy Fighter" by the manufacturer, the 2PA was powered by a Wright R-1820-G2 or G3 Cyclone nine-cylinder radial engine, the former rated at 1,000&nbsp;hp for take-off and the latter at 875&nbsp;hp. Armament comprised two wing-mounted 7.62&nbsp;mm or 12.7&nbsp;mm Browning guns, one 7.62&nbsp;mm Browning on a flexible mount in the rear cockpit, plus two forward-firing fuselage-mounted 7.62&nbsp;mm or 12.7&nbsp;mm Browning guns. Provision was made for a bomb load of up to 227&nbsp;kg (500&nbsp;lb) on internal wing racks. One 2PA-A and one 2PA-L were procured by the Soviet Union in March 1938, one with conventional landing gear and one with floats, along with the manufacturing license, but it appears that the Soviets never put it into production. In what proved to be an unpopular move for Seversky, 20 '''2PA-B3'''s were sold to the [[Imperial Japanese Navy|Japanese Navy]], which briefly employed them in the [[Second Sino-Japanese War]] as '''Navy Type S Two-Seat Fighter''' or '''[[Seversky A8V|A8V-1]]''' (Allied codename "Dick"). The Japanese were unimpressed with the aircraft and eventually relegated two of them to the [[Asahi Shimbun]] newspaper as "hacks." Sweden ordered 52 2PAs (Swedish designation '''B 6'''), able to carry 1,350&nbsp;lb (612&nbsp;kg) of bombs, but received only two prior to the U.S. embargo directed to combatants.<ref name="Fitzsimmons p. 905"/> The remaining 50 were appropriated by the USAAC, re-armed with 0.30&nbsp;in and 0.50&nbsp;in machine guns, and used as advanced trainers named '''AT-12 Guardsman'''.

==Operational history==
[[File:P35-6.jpg|thumb|right|P-35 of [[27th Fighter Squadron|27th Pursuit Squadron]], 1st PG, in flight.]]

===United States Army Air Corps===
The first P-35s were delivered to the [[1st Operations Group|1st Pursuit Group]] (27th, 71st and 94th PS) stationed at [[Selfridge Field]] in Michigan. The aircraft used a [[wet wing]] to save weight and ground personnel quickly learned about the persistent fuel leaks. The P-35's performance was poor even by contemporary standards and, although USAAC aviators appreciated the aircraft's ruggedness, it was already obsolete by the time deliveries were finished in 1938.<ref name="Hucker p. 72"/>

On 18 June 1940, United States declared an embargo against exporting weapons to any nation other than the United Kingdom. Optimistically, Republic continued to manufacture EP-106s which, by the 24 October 1940 order, 60 were taken over by the USAAC as the '''P-35A'''. The aircraft were re-armed to American standards with a pair of 0.50&nbsp;in machine guns that fired through the propeller, but retained the Swedish specification of a 0.30&nbsp;in machine gun mounted in each wing. Flight instruments were metric, and both their labeling and flight manuals written in Swedish. Of these, three aircraft were kept in United States as instructional airframes for mechanics. Six P-35As were delivered to Ecuador to form the first combat unit, the ''Escuadrilla de Caza''.<ref>[http://www.aeroflight.co.uk/waf/americas/ecuador/AirForce/Ecuador-af-home.htm "Ecuador Air Force."] ''aeroflight.co.uk.''

===Philippine Army Air Corps===
[[File:Delcarmen-1941.jpg|thumb|USAAF P-35 fighters and [[Douglas B-18 Bolo|B-18]] bombers at Del Carmen Field, Philippines, October 1941]]
The remainder were sent to the [[Far East Air Force (United States)|Far East Air Force]] in the [[Philippines]] beginning in February 1941. Eventually all pilots of the three pursuit squadrons on Luzon transitioned to the P-35A from the [[Boeing P-26 Peashooter|P-26]]. About 10 of these were lost in accidents. The P-35s were used primarily as gunnery trainers by all three squadrons because of a critical shortage of .50-caliber ammunition in the Far East Air Force, placing a strain on the engines of all the aircraft since no replacement engines were available. In October 1941, the P-35s were earmarked for transfer to the [[Philippine Army Air Corps]] after sufficient [[Curtiss P-40 Warhawk]]s were received by the FEAF.

In November 1941, after the 3rd and 17th PS received new P-40E aircraft, most of their P-35As were passed to two newly arrived squadrons attached to the group, the 21st and 34th PS, with the latter receiving most. The 21st PS received its P-40Es on the eve of war and transferred its few P-35s to the 34th Pursuit Squadron, which then had nearly a full squadron.<ref name="bloodyv1 p47, 56">Shores, Cull and Izawa 1993, pp. 47, 56.</ref> It then fought with them in the futile defense of the islands in December 1941, initially at [[Del Carmen Airfield]]. They were hopelessly outclassed by the Japanese fighters. Lack of armor and self-sealing fuel tanks made the aircraft extremely vulnerable (12 P-35As were destroyed and six damaged by a Japanese [[strafing]] attack on Del Carmen Airfield on 10 December<ref name="bloodyv1 p178">Shores, Cull and Izawa 1992, p. 178.</ref>) and by 12 December 1941, only eight P-35As were still in flying condition.<ref name="Hucker p. 72">Hucker 1984, p. 72.</ref> However, also on 10 December 1941, a P-35A of the [[34th Pursuit Squadron]] piloted by 1st Lt. Samuel H. Marrett is credited with the sinking of Japanese minesweeper [[Japanese minesweeper No. 10 (1938)|W-10]] during the [[Japanese invasion of Vigan]] in northern [[Luzon]]. Marrett made multiple strafing runs against ''W-10'', until the ship blew up. The explosion was so powerful it tore a wing off of Marrett's P-35, causing him to crash into the sea.<ref>{{cite web |url=http://www.combinedfleet.com/W-10_t.htm |title=IJN Minesweeper W-10: Tabular Record of Movement |last1=Hackett |first1=Bob |last2=Cundall |first2=Peter |year=2012 |website=combinedfleet.com |access-date=20 April 2014}}</ref>

In late December 1941, most of the remaining strength of the Army Air Force in the Philippines was evacuated to airfields on the [[Bataan Peninsula]].<ref name="bloodyv1 p1945">Shores, Cull and Izawa 1992, pp. 194–195</ref> On 2 January 1942, five surviving P-35As attempted to fly from [[Pilar, Bataan|Pilar]] Field to [[Bataan Airfield]], but two were hit by anti-aircraft fire, with one crashing and the second returning to Pilar where it was wrecked on landing.<ref name="bloodyv2 p127">Shores, Cull and Izawa 1993, p. 127</ref> On 11 January, the two remaining P-35s evacuated to [[Del Monte Airfield]] on [[Mindanao]], carrying several unit personnel in their baggage compartments.<ref name="bloodyv2 p131">Shores, Cull and Izawa 1993, p. 131</ref> On 4 April, they returned briefly to Bataan to evacuate other personnel, and one was lost crash-landing on Cebu on 10 April. The sole surviving P-35 was turned over to Capt. Ramon Zosa of the PAAC on 30 April, and flew its last sortie out of Del Monte Airfield, accompanying a P-40 on a strafing attack of Japanese landings at Macajalar Bay on 3 May 1942.

===Sweden===
The [[Swedish Air Force]] received 60 J 9s in the spring-summer 1940. The aircraft were operated alongside other units assigned to the [[Svea Air Corps|Svea Air Force Wing]] (F 8) protecting Stockholm, replacing the obsolete [[Gloster Gladiator]]s.<ref>[http://www.avrosys.nu/aircraft/Jakt/109J9.htm "J 9 – Republic Seversky EP-1 (1939–1952)."] ''Avrosys.nu.'' Retrieved: 10 October 2010.</ref> Swedish J 9s served with [[Flygvapnet]] as a fighter until 1946. Later, 10 aircraft were equipped with cameras but retained their J 9 fighter designation and, in addition, a number of others were used for liaison and general flight training. The last seven J 9 aircraft remained in service until September 1952.<ref>Andersson, Lennart and Leif Hellström. ''Bortom Horisonten: Svensk Flygspaning mot Sovjetunionen 1946–1952'' (in Swedish).
