Curtiss Hawk 75A/Mohawk. Part eleven. The Hawk in Norwegian hands.

 
The history of the Norwegian Hawks began in 1938, when the Norwegian government decided to modernize its aerial fleet. Since its own aviation industry was not prepared to develop modern aircraft, it was decided to purchase them abroad.These initial purchases resulted in a dozen of British Gloster Gladiator biplanes, which, although they were not as modern as the German machines, they were modern enough to allow a smooth transition from older biplanes to all-metal fighters, which significantly improved performance.However, the initial plan was to equip the whole aerial fleet with modern monoplanes with retractable landing gear.During the very early war Norway remained neutral. However, the Munich Crisis made it clear that the Germans would not be overly concerned if war broke out. To counter those pressures, the Norwegians needed new aircraft immediately, so in June 1939  a commission headed by Eckhoff, Motzfelt and Reistad (Norwegian Army representatives) was sent to the United States, where they were offered designs from Seversky and Vultee. However, it was clear that the U.S. Army Air Corps itself was struggling with the P-35 and Vultee was unable to produce large numbers of aircraft in a short time, so Curtiss became the only design alternative.On 12th August a contract was signed for the purchase of 12 A-6 Hawks, basically identical to the French A-1, except that the 7.9mm machine-guns were assembled in Buffalo, New York, instead at the customer's facility, as it was the case with the French aircraft. In addition to purchase the pre-built aircraft, the Norwegians obtained the rights to manufacture 24 at their own facility in Kjeller, near Oslo.
On 27th September, with the war already underway, it was clear that the deadline, set for 1st July 1940, could not be completed, so Norway decided to expand its order by another 12 completed aircraft to equip the next squadron. The first of this new batch arrived in Oslo on 20th February 1940, followed by 18 more in four batches from 15th March to 1st April. By 9th April one aircraft was waiting at Kjeller, ready to begin trials and with its armament mounted, five were also in various stages of assembly waiting to be completed at Kjeller (including three unarmed ones), and five were still in crates in Bergen. Of the eight that arrived in Oslo on 1st April, some had been delivered to Kjeller, and five were still on board SS Idefiord transport ship.
The two dozen Hawk plus twelve Gladiators, were not a force that could hold the German Luftwaffe, and Norway was well aware of this, so in January 1940 it was decided to send another delegation to the USA. It arrived in Washington in late February 1940 and was led by Captain Motzfeldt, from the army and Ostby from the Navy. They immediately headed to the Curtiss-Wright factory and a contract for 29 Hawks was quickly negotiated and expanded later to include seven more aircraft. Therefore, a total of 36 Hawks were ordered. In addition, 36 Douglas 8A Nomad bombers and 24 Northrop N3P-B patrol seaplanes were also purchased.
The Hawks chosen by the Norwegians were the Hawk 75A-8 variant, which was identical to the French A-4 with Wright engines. The latter was armed with two 12.7mm (0.50") Browning machine guns.
Externally the A-8 version was recognizable by the teardrop-shaped radome on the fuselage aft the cockpit, to host the radio half-compass antenna. The first of these aircraft, together with other ten, was to be delivered between December 1940 and 25th January 1941 but, as expected, they were never delivered.
The German attack on Norway found most of the Hawks in crates. Only a few were assembled, and even these did not see combat. It's most likely that some were destroyed during aerial bombing raids. After the German invasion, the Norwegians attempted to hide the aircraft that survived, but the Germans found them all.
It's estimated that there were nineteen of them. Almost all, if not all, were later brought to Germany, where they were adapted to local standards by replacing some equipment, such as sights.
The Norwegian Hawks did not serve for long time. Thirteen of them were later transferred to Finland, while the fate of the remaining six is unknown.
While all that was taking place, the five aircraft aboard SS Idefiord had returned to England, where they were briefly considered for combat in northern Norway, but the idea never materialized due to the lack of radio and armament. They were then offered to France, but the French declined before the offer could be accepted.
Eventually, on 24th September 1940 the Royal Air Force (RAF) purchased them from Norwegian representatives in London, together with four Heinkel He.115s also previously owned by Norway, for the low price of £86,000. These five five Hawks were most likely AR-630 to AR-634.
After the fall of Norway, the purchasing committee members, still in the United States, were left with 96 ordered aircraft and a hundred Cyclone engines. Initially, they intended to resell them to Great Britain, but the RAF didn't want American aircraft because building the entire infrastructure for such a small number would be too expensive, and besides, they already had their better designs. Another idea was to replaced the ordered Hawk 75A-8 with P-40s built for the RAF, but this idea was also never implemented.
At the same time, in the United States, the Norwegian legation's air attaché, Oscar Klingenberg, stepped in came up with the idea of organizing training squadrons for Norwegians pilots in Canada, following the example of the RAF. Klingenberg contacted the Canadian consul in Washington and received assurances that an air base in Toronto could made available to him shortly. The Norwegian diplomat chose Canada for two good reasons: First, the British had virtually no available bases on the islands and second, the ordered Hawk 75A-8s were still in the United States, so transporting them to Canada meant no problem at all. Ultimately the airfield on Lake Ontario was leased indefinitely, and a headquarters was established in the suburbs of Toronto. The entire complex soon became known as "Little Norway".
The first 36 Hawks arrived at Toronto on 16th December 1940 with the last one landing on 4th February 1941. There, the aircraft were assembled and tested. Together with the Hawks, the ordered Douglas bombers were also delivered, making this unit's total to 72 aircraft. This was too many for its needs, and since both aircraft were not intended for operational service, it was decided to put half of them up for sale. 
Peru soon purchased the surplus Hawks, and earlier countries such as Canada, China, the Soviet Union and Belgium had expressed interest. Peru didn't buy the Hawks directly from the Norwegians, but through the United States Army Air Corps (USAAC), which first bought them and re-designated the fighters as RP-36G, with the letter "R" standing for "Restricted" meaning that they were undervalued as front-line aircraft but could be useful in second-line duties. They were also given new serial numbers and were delivered to the USAAC between 18th June and later July 1941 and were later transferred to Peru under a Lend-Lease agreement.
Shortly after the Norwegians decided to close their school and continue training pilots within RAF units. The remaining aircraft, including 12 Hawks (six of which were involved in accidents and were written off), were reacquired by the USAAC and were renumbered and designated P-36G to be later sold to Peru, as previously stated.
One aircraft crashed during a flight from Toronto to the United States. When the Norwegians disposed of their aircraft, they also sold the radio equipment, which the Peruvians did not need. Initially, they categorically refused to pay for the Lear radios, which were no longer needed there, but the firm stance of "Little Norway" meant that the additional $90,000 was regretted, and the radios were purchased along with the aircraft.

Supermarine Spitfire. European Users, part twelve. The Spitfire in Norwegian hands.

 
There were two Norwegian squadron serving with the Royal Air Force (RAF) during World War 2. Those were Nos. 331 & 332.
  • No.331 (Norwegian) Squadron: This unit was initially equipped with the Hawker Hurricane at its formation on 21st July 1941 but it did not last long until they were switched by the Spitfire Mk. II in November 1941. They were assigned to the aerial defence of Scotland until May 1942 when they were rebased to southern England. 
    On 6th May they conducted their first sweep over France and the squadron was assigned to offensive duties for the remainder of the war, working alongside with the other Norwegian squadron of the RAF, No. 332. 
    In August this unit took part in the aerial support for the raid Dieppe raid. 
    On 31st March 1944 they were assigned to 2nd Tactical Air Force, which now was operating in the fighter-bomber role and, in August 1944 they were rebased to Normandy to support the breakthrough operations towards inland France. This squadron followed the Allied advanced east and operated from several bases in Low Countries from October onwards. They provided aerial cover for the Allies as they advanced into Germany from 1945 until the end of the war in Europe. 
    In late April 1945 the squadron went back to the United Kingdom and shortly after the war, they were rebased in Norway where, in November 1945 the whole squadron was transferred to the Royal Norwegian Air Force.
  • No. 332 (Norwegian) Squadron: This unit operated the Spitfire since its inception in January 1942. It was formed at RAF Catterick (northern England) and became operational in March 1942. In June they were rebased to south of England where they performed various fighter sweeps over occupied France. 
    Based at North Weald, together with No. 331 they formed a RAF Wing which provided aerial support for the Dieppe Raid in August 1942. 
    Together with No. 331 it was assigned to the 2nd Tactical Air Force (albeit it's not clear if No. 332 was assigned sooner or later than No. 331 as sources claim that No. 332 was assigned in late 1943). With the 2nd Tactical Air Force, this squadron's role was changed to the fighter-bomber one to provide aerial cover for Operation Overlord (the Normandy Landings in June 1944). In mid-August 1944, together with No. 331 they were rebased to Normandy to provide aerial support for the Allied forces in their advance into France and later in the advance of Allied forces into the Netherlands.
    In late April 1945 the squadron was moved to Scotland and after the war, in September 1945 they were sent to Norway where on 21st September, they were transferred to the Royal Norwegian Air Force.
As both RAF's Norwegian squadrons were allowed to retain their equipment, they formed the bulk of Norway's post-war fighter force, divided into two squadrons- 331 & 332 Skvadron (Norwegian for 'Squadron') and they were kept until 1951 in service with 331 Skvadron and 1952 in service with 332 Skvadron . The Mk. IX were only replaced by the jet-powered Republic F-84G Thunderjet. 
In 1949, the Royal Norwegian Air Force acquired more than 30 Spitfire Mk. IX plus three Spitfire PR. XI, which was a reconnaissance variant of the Mk. IX. The PR.XI formed a special photo-reconnaissance flight which employed the PR.XI until March 1954 when the unit was renamed to 717 Fotorekognoseringsving and were re-equipped with the Republic RF-84E (the recon variant of the F-84E).
A total of 68 Spitfires flew with the Royal Norwegian Air Force and received the registration codes A-AB to A-AZ, A-BA to AB-Z and A-CA to A-CW.
The three PR. XIs were initially designated A-ZA to A-ZZ but their designations soon changed to A-ZA, A-ZB and A-ZC.

Caproni Ca.310, foreign users, part one


 The Caproni Ca.310 'Libeccio' (Italian word for "south-western wind") , was an Italian twin-engined reconnaissance monoplane used during World War II. The aircraft itself was a derivation of the previous Ca.309 and it was employed by many users around the world. Among them, the following ones:
  • Independent State of Croatia: The Air Force of the Independent State of Croatia (whose acronym was ZNDH) employed 6 (seven, according to some other sources) Ca.310. Five of them were bought from German stocks, which were ex-Yugoslav machines and one machine captured by themselves, plus one Ca.310bis (which was a variant with an unstepped glazed nose, which would eventually become the prototype for the Ca.311). 
    A single ZNDH Ca.310 fleed to Italy on 31st October 1943 and landed at Tortorella airfield, controlled by the South African Air Force. That airplane was loaded with 7 Yugoslav and one Gestapo officer. Of those people, the most important was Cpt. Janko Dobnikar a Slovene pilot working for Zemun WNF (ex Ikarus) who was arrested the previous day by the Gestapo for cooperating with partisans but the flight was hijacked and sent to Italy.
  • Hungary: Hungary bought a total of 36 Ca.310 in 1938. Three of them were soon lost to accidents and the Hungarians were not satisfied with the type's performance, so during the next year (according to some other sources it was in 1940) the remaining 33 machines were sent back to Caproni. They were taken into account for the MKHL's (Hungarian acronym for Magyar Királyi Honvéd Légiero - Royal Hungarian Air Force) purchase of the Caproni Ca.135bis medium bomber. Returned aircraft were refurbished and assigned to the 50º Stormo Assalto, to replace the Breda Ba.65 as part of the 12º Gruppo of the Regia Aeronautica (Italian Royal Air Force)
  • Norway: Norway ordered 24 Ca.310 as part of a dried and salted cod barter between Norway and Italy. After the delivery of the first four aircraft, testing revealed that flying characteristics weren't as satisfactory as Caproni had promised and build quality fell way behind too. Therefore, Norwegian authorities cancelled the order and any further Ca.310 wasn't delivered. The four Norwegian machines received the following serial numbers: 501, 503, 505 and 507. Aircraft No. 503 was bought by the Norwegian national airline Norske Luftfartselskap and was employed as a fast mail aircraft in the Oslo-Göteburg (Sweden)-Copenhagen (Denmark) night route during summer 1939. By the start of the war it was recalled by the Haerens Flyvevaaben (Norwegian Army Air Service) and was put back into military service.
    When Germany attacked Norway on 9th April 1940, all four Norwegian Ca.310 were based at Sola airfield, where they were called to move to Oslo, to defend the capital, but two of them, numbers 503 and 507 were destroyed on the ground by the Luftwaffe. One Ca.310, number 505 managed to take off, but it was destroyed by its own crew after having to perform an emergency landing at Opstad. The other surviving machine, number 501 managed to take off from Sola, although having been damaged, but eventually it crashed in lake Vangsmjosa, in the region of Valdres on 19th April 1940. This aircraft was recovered and restored and is nowadays on exhbition at the Sola aircraft museum.

Junkers Ju.52/3m in Norwegian and Polish service

 
The Junkers Ju.52/3m is a German cargo plane which was manufactured by the thousands and saw service worldwide, in every continent. Among its many users, we're covering the following ones in this post:
  • Norway: The Norwegian airline Det Norske Luftfartselskap (DNL - Norwegian national airline, forerunner of Norwegian Air Lines) acquired 6 float-equipped Junkers Ju.52/3m (according to some sources they were just four) in 1935. In June 1936 the first Ju.52/3m (which crashed shortly after making its first maiden voyage, on 16th June and had to be replaced by a new one two weeks later) was delivered to serve in a seasonal summer route between Bergen and Tromso with flights three times per week with stopovers at Alesund, Molde, Kristiansund, Trondheim, Bronnoysund, Sandnessjoen, Bodo, Narvik and Harstad. 
    In 1937 DNL moved the departure point to Gressholmen seaplane port, in Oslo, the Norwegian capital. 
    They kept on serving with DNL until the outbreak of the war when the Marinens Flyvevesen (Norwegian for Royal Norwegian Navy Air Service) took one into service in January 1940 (though some sources claim it was in December 1939) and fitted with a ventral defensive machine gun gondola, plus another one in a dorsal position. It served until 9th April. 
    When Norway was occupied, the Luftwaffe took over every aircraft from DNL. However, after the war, one that was originally registered as LN-DAH was taken back and served until 1956.
    Two ex-Luftwaffe Ju.52/3mg7es were taken over on VE-Day (8th May 1945) and, together with LN-DAH, they were incorporated into DNL's fleet. One Ju.52/3m registered as LN-LAB, crashed in May 1946 at Snaroya, close to Oslo. In August that year some Ju.52 were taken by the Kongelige Norske Luftforsvaret (KNL - Royal Norwegian Air Force) and served until September 1950 when they were sold to Portugal.
  • Poland: On 16th November 1936, LOT (Polskie Linie Lotnicze LOT S.A.) received a single Ju.52/3m powered by Bristol Pegasus engines in exchange for nine Junkers F-13s. This Ju.52/3m was registered as SP-AKX and, from early 1937 onwards, it flew regular flights from Warsaw to Berlin, Rome and Salonique, in Greece. As this machine was powered by Pegasus engines, which were heavier than the original BMW's ones, an extra water tank was installed at the rear of the aircraft to get the right centre of gravity when in flight. 
    This machine was widely used, recording a total of 600 flight hours in 1937 and 843 hours in 1938 suffering no accidents or setbacks whatsoever. At the outbreak of World War 2, it was flown from Zabczyce, close to the city of Pinsk, in Polesie, to the Romanian capital, Bucharest on 12th September 1939 where it was planned to be sold to Turkey but, eventually, it was fictionally sold to Imperial Airways and received the registration G-AGAE.

Arado Ar.196 - Foreign users, part three

Now it's time to tell the story about the Arado that fell in British hands.
When Germany invaded Norway in April 1940, an Arado Ar.196 belonging to the German Heavy Cruiser Admiral Hipper was captured in the Norwegian city of Lyngstad by a Norwegian made Marinens Flybebaatfabrikk MF.11 on 8th April.
It was towed to Kristiansund by a Norwegian torpedo boat where it was repainted with Norwegian markings. Later, on 18th April, it was flown to the United Kingdom by a Norwegian pilot. It was crashed shortly after when it was on transit to Helensburg naval air base to test it.
When the war ended, at least one operational Ar.196 was left behind by the Germans and it was used by the post war Royal Norwegian Air Force until 1946, operating on Norwegian west coast.
Two Arado Ar.196 were interned in Sweden during the war. The first one when was on its way from Copenhagen to Borholm, it lost its way due to a compass malfunction and entered Swedish airspace, where it was forced to ditch. It remained in Sweden, where it was tested by the F.2 Squadron based in Hägenäs and then it was sold to the Kontinentagentur AB company. After the war, it was flown to Norway where it served with the 8801 RAF Wing and in June 1945with the No.330 (Norwegian) Squadron based in Stavenger Sola.
