• Design and development
    The Junkers 290 was developed directly from the Ju 90 airliner, versions of which had been evaluated for military purposes, and was intended to replace the relatively slow Focke-Wulf Fw 200 Condor which by 1942 was proving increasingly vulnerable when confronted by Royal Air Force aircraft; the Fw 200's airframe lacked sufficient strength for the role in any case. The Ju 290 was also intended to meet the need for large transport aircraft. A bomber version, the A-8, was planned, but never built.Design was headed by Konrad Eicholtz.

    The development programme resulted in the Ju 290 V1 prototype BD+TX, which first flew on 16 July 1942. It featured a lengthened fuselage, more powerful engines, and a Trapoklappe hydraulic rear loading ramp. Both the V1 and the first eight A-1 production aircraft were unarmed transports. The need for heavy transports saw the A-1s pressed into service as soon as they were completed. Several were lost in early 1943, including one taking part in the Stalingrad Airlift, and two flying supplies to German forces in Tunisia, and arming them became a priority.

    The urgent need for Ju 290s in the long-range maritime reconnaissance role was now also high priority, and resulted in the Ju 290A-2. Three A-1 aircraft were converted to A-2 specification on the assembly line. Production was slow due to the modifications necessary and the installation of strong defensive armament. The A-2 was fitted with FuG 200 Hohentwiel low-UHF band search radar and a dorsal turret fitted with a 20 mm MG 151 cannon. The Hohentwiel radar was successfully used to locate Allied convoys at ranges of up to 80 km (50 mi) from an altitude of 500 m (1,600 ft) or 100 km (62 mi) from an altitude of 1,000 m (3,300 ft). It allowed the Ju 290 to track convoys while remaining out of range of anti-aircraft fire.

    The A-3 version followed shortly after with additional navigational equipment and a heavier defensive armament. It was fitted with two hydraulically powered HDL 151 dorsal turrets armed with 20 mm MG 151/20 cannons, with a further 20 mm MG 151/20 and a 13 mm (.51 in) MG 131 machine gun fitted in a typically German Bola gondola (a fitment for almost all German WW II bomber aircraft) directly underneath the forward dorsal gun turret, and a 20 mm MG 151/20 fitted in the tail operated by a gunner in a prone position. Two 13 mm (.51 in) MG 131s were also fitted in waist positions (Fensterlafetten). The A-3, along with the A-2, also featured large fuselage auxiliary fuel tanks. Both retained the rear loading ramp so that they could be used as transports if required. The A-5 variant was fitted with increased armour protection, dual 13mm MG 131 in a rear-facing position in the gondola. and had two dorsal turrets, operating either a 20mm MG 151/20 or a MG 151/15. The last A-5, W. Nr. 0180, carried two 20mm MG 151 cannon in lieu of the smaller MG 131.The A-5 had the capability of launching Fritz X and other guided munitions.

    The improved A-7 version appeared in spring 1944; 13 were completed, and 10 served with the long-range reconnaissance group, Fernaufklärungsgruppe (FAGr) 5. Some A-7s and some A-4s were fitted with a detachable nose turret armed with a 20 mm MG 151/20 for added defense against frontal attack. No bombs were carried, as it was intended that the A-5 and A-7 would be fitted with the FuG 203 Kehl radio guidance system to launch MCLOS-guided Fritz X and Hs 293 anti-ship missiles.

    Production lines were set up at the Letov aircraft factory in Prague for combat versions of the aircraft, commencing with the Ju 290 A-2, which carried the aforementioned Hohentwiel maritime search radar for its patrol role. Minor changes in armament distinguished the A-3 and A-4, leading to the definitive A-5 variant. The A-6 was a 50-passenger transport aircraft.

    The B-1 was a high-altitude heavy bomber that was the last variant to be built; a B-2 version was also under development.
    Operational history
    A special long-range reconnaissance group, FAGr 5 (Fernaufklärungsgruppe 5), had been formed on 1 July 1943 and during the late summer of 1943 three of the new Ju 290 A-2s were delivered to its 1 Staffel, which became operational at Mont-de-Marsan near Bordeaux on 15 October of that year. They flew their first operational missions in November 1943, shadowing Allied convoys in cooperation with U-boats, often remaining airborne for up to 18 hours.

    Five Ju 290 A-3 aircraft with more powerful BMW 801D engines in unitized mounts followed, as did five Ju 290 A-4 aircraft with improved dorsal turrets mounting 20 mm MG 151/20s. The Ju 290s were well suited to their patrol role and began replacing the Fw 200 Condors. An A-4, Works no. 0165, was experimentally equipped with attachments for FX 1400 PGM, and either the Henschel Hs 293 or Hs 294 anti-ship missiles, and fitted with the FuG 203e Kehl MCLOS radio control transmitter system for controlling any of them after release; it was surrendered to the US after the war and flown across the Atlantic to the USA.

    In November 1943, a second Staffel was activated and, with a range of over 6,100 km (3,790 mi) the Ju 290s ranged far out over the Atlantic, relaying sightings of Allied convoys to U-boats. 11 Ju 290 A-5s with increased armour, heavier armament and self-sealing fuel tanks were delivered to FAGr 5 early in 1944, as were around 12 of the Ju 290 A-7 version; the A-7 could carry three Hs 293 glide bombs or Fritz X armoured, anti-warship precision-guided munitions when fitted with the FuG 203 Kehl radio guidance system for them, and featured a redesigned nose section which combined a 20 mm cannon installation with the FuG 200 radar aerial array.

    Towards the end of 1943, Admiral Dönitz demanded that the entire output of Ju 290s be made available for U-boat warfare. However, only 20 were assigned for this purpose. Even though both Hitler and Dönitz demanded an increase, the Luftwaffe General Staff declared it was unable to assign any more for naval reconnaissance purposes. The General Staff argued that there could be no increase in output so long as the Luftwaffe was not conceded "precedence in overall armaments".

    In the spring of 1944, after Albert Speer had taken over the direction of air armaments, the Luftwaffe High Command boldly announced that production of the Ju 290 was to be suspended despite it being urgently needed for maritime reconnaissance; suspending production meant that resources could instead be diverted to building fighters. At that point in time, Speer's position was weak and Hermann Göring was trying to find allies to help him strip Speer of his power, and the Luftwaffe was not prepared to offer the Navy more than "goodwill".

    On 26 May 1944, shortly after daybreak, a Sea Hurricane piloted by Sub Lieutenant Burgham from the escort carrier HMS Nairana shot down Ju 290 9V+FK of FAGr 5 over the Bay of Biscay. The afternoon of the same day, Sub Lieutenants Mearns and Wallis attacked two more Ju 290s. Mearns shot down 9V+GK piloted by Kurt Nonneberg, which ditched in the sea. The other Ju 290 disappeared on fire into cloud and was assumed to have crashed.

    As the Battle of the Atlantic swung irrevocably in favour of the Allies with the loss by the Germans of French bases in August 1944, FAGr 5 withdrew eastwards and the remaining Ju 290s were reassigned to transport duties, including service with KG 200, where they were used to drop agents behind enemy lines and other special missions.

    Ju 290 A-5, works number 0178, D-AITR, Bayern of Luft Hansa flew to Barcelona on 5 April 1945, piloted by Captain Sluzalek. The aircraft suffered damage to its landing gear on landing and was repaired with parts brought from Germany by a Lufthansa Fw 200. It remained in Spain because the Spanish Government ordered that regular Luft Hansa flights on route K22 be terminated from 21 April and was turned over to the Spanish authorities.
    Flights to Japan
    Following the invasion of the Soviet Union in June 1941, plans were made to connect Germany and Japan by air using Luftwaffe aircraft modified for very long range flights. Commercial flights to the Far East by Lufthansa were no longer possible, and it had become too dangerous for ships or U-boats to make the trip by sea. Field Marshal Erhard Milch authorised a study into the feasibility of such direct flights. Various routes were considered, including departing from German-occupied Russia and Bulgaria. Nautsi, near Lake Inari in the north of Finland, was finally selected as the optimum starting point for a great circle route along the Arctic Ocean then across eastern Siberia, to refuel in Manchuria before completing the flight to Japan.

    In 1943, the Ju 290 was selected for the flights and tests began in February 1944 of a Ju 290 A-5 (works number 0170, Stammkennzeichen factory code of KR+LA) loaded with 41 tonnes (45 tons) of fuel and cargo. Three Ju 290 A-9s (works numbers 0182, 0183 and 0185) were modified for long-range work at the Junkers factory in March 1943. The plan was eventually put on indefinite hold after the Japanese failed to agree on a route, as they did not want to provoke the Soviet Union by an overflight of Siberia, and the three aircraft were eventually transferred to KG 200 without any attempt at a long-range flight to Japan.

    The idea for a flight to Japan was revived again in December 1944 to transport Luftwaffe General Ulrich Kessler to Japan as a replacement for the German air attaché in Tokyo. Ju 290 A-3, no. 0163, was flown to Travemünde for the necessary modifications, but the work was delayed and it was decided to send Kessler aboard the submarine U-234 instead. The aircraft was destroyed on 3 May 1945 as British troops arrived. Some sources claim that the trip to Japan took place, departing from Odessa and Mielec and landing in Manchuria.
    KG 200
    The Luftwaffe Special Operations squadron, KG 200 used the Ju 290 amongst its various aircraft types. Their best-known Ju 290 mission was flown on the night of 27 November 1944. KG 200 pilots Braun and Pohl flew a Ju 290 from Vienna to a position just south of Mosul, Iraq, where they successfully air-dropped five Iraqi parachutists. Staging through the island of Rhodes, which was still under German occupation, they evacuated some thirty casualties from there to Vienna.
    Hitler's personal transport
    On 26 November 1943, Ju 290 A-5, no. 0170, along with many other new aircraft and prototypes, was shown to Adolf Hitler at Insterburg, East Prussia. Hitler was impressed by its potential and told Göring that he wanted a Ju 290 for his personal use. A Ju 290 was not however assigned to the Fliegerstaffel des Fuehrers (FdF) until late 1944, when an A-7 was supplied, works number 0192, which had formerly been assigned to FAGr 5. Modifications were completed by February 1945 at the FdF's base at Pocking, Bavaria, a Stammkennzeichen alphabetic designation code of KR+LW being applied. Hitler's pilot, Hans Baur, tested the aircraft, but Hitler never flew in it.

    The aircraft was fitted with a special passenger compartment in the front of the aircraft for Hitler, which was protected by 12 mm (.5 in) armour plate and 50 mm (2 in) bulletproof glass. A special escape hatch was fitted in the floor and a parachute was built into Hitler's seat; in an emergency it was intended that he would put on the parachute, pull a lever to open the hatch, and roll out through the opening. This arrangement was tested using life-size mannequins.

    Hans Baur flew the aircraft to Munich-Riem airport on 24 March 1945, landing just as an air-raid alert was sounded. He went home after parking it in a hangar but on returning to the airport, he discovered that both hangar and aircraft had been destroyed by American bombers
    Germany's Last Ju 290s
    Despite the end of reconnaissance operations from France and the Amerika bomber program, starting in September 1944 three more Ju 290s were constructed for "special purposes" by Junkers. Their works numbers are unknown. What those "special purposes" were, or if they ever came to be, is unknown.

    A number of Ju 290s survived the war, the Allies evaluating at least three examples, none of which was known to have survived intact into the 21st century.

    Ju 290 A-4 no. 0165, which had been equipped with attachments for Fritz X, Hs 293, and Hs 294 PGM ordnance, and fitted with FuG 203e Kehl radio guidance gear for controlling such PGM ordnance, was surrendered to the U.S. Renamed Alles Kaputt, and numbered FE 3400, it was flown to the US by Colonel Harold E. Watson from Orly, Paris to Wright Field on 28 July 1945, via the Azores.

    The captured aircraft, with its Nazi insignia repainted, was a frequent performer at air shows at Freeman Field and Wright Field. When the aircraft was scrapped at Wright Field in 1946, a plastic explosive device of German manufacture was discovered in the wing near to a fuel tank.

    An A-5 (Wk. no. 0178), Bayern of Luft Hansa, which had been interned at Barcelona, was acquired by the Spanish and was eventually used by the Spanish Air Force from 29 April 1950 to 27 July 1956 as a government transport of personnel for the Superior School of Flight in Salamanca. Following an accident, it was scrapped due to a lack of spare parts in May 1957.
    Ju 290 Spanish
    A final Ju 290 was built by the Letov Kbely aircraft company in Czechoslovakia in 1946, using parts intended for the Ju 290 B-1 high-altitude prototype. It was completed as a transport with capacity for either 40 or 48 passengers (sources vary), and designated Letov L-290 "Orel" (Eagle). It was offered as an airliner but was not adopted because it lacked the appropriate internal equipment, and the BMW engines were not available in sufficient numbers.
