== History ==

=== Initial development ===
During WWII, Sweden had effectively fallen behind in the development of military aircraft. This was largely due to a severely underdeveloped aircraft engine industry in Sweden which meant that there were no high-end engines available for aircraft production. Thus Sweden was still projecting propeller-driven fighter aircraft in 1945 equivalent to fighters projected by other nations 1-3 years prior. Since it was obvious by 1945 that jet aircraft was the future the Swedish Air Force decided to immediately scrap all propeller-driven fighter projects and instead make the jump to a jet fighter. Sweden's leading aeronautical firm SAAB, who was already actively working with the Swedish Air Force on the previously mentioned propeller fighters, was tasked with projecting this new jet fighter. Several designs were looked at but by mid-1945 it was decided that a mid-high wing aircraft with a central air intake would be the best option. Due to the mid-high wing it was not possible to house the landing gear in the wings. Instead, it was decided to house the landing gear in the fuselage of the aircraft. This concept got the project name R1001, R standing for "reaktionsmotor" (reaction engine), the Swedish military term for jet engines.

The original specifications for the R1001 called for a radar rangefinder, four Bofors 20 mm akan m/45 cannons mounted in the nose with 180 rounds per gun, external fuel tanks and a top speed of 1,000 km/h. The engine was originally supposed to be an indigenous design by the company STAL but by late 1945 Sweden had gotten the green light for acquiring the British "in development" de Havilland Ghost engine. There are several reasons why Sweden was allowed to buy this new powerful engine even before it was finished, but the two main factors were the economic state of Britain after the war and Sweden's good relations with the company de Havilland. The engine was however not the only thing which changed at an early stage. Originally the R1001 featured straight wings, as was common at the time. However, by pure luck Sweden was able to acquire some German WWII research papers from a Swiss source regarding swept wings on aircraft and their increased performance at high speeds. Thus it was decided to change the R1001 design to feature swept wings. The first blueprints of the R1001 featuring swept wings were finished by late 1945 and within 3 years a prototype had been constructed and was ready for flight testing. During these 3 years the design would change even further from the original concept. The radar rangefinder was dropped for unknown reasons, and the Bofors cannons were switched for Hispano designs due to delays at Bofors. By 1947 the aircraft had also received the designation J29.

=== Testing and production ===
The J29 prototype flew for the first time on the 1st of September 1948 and immediately showed incredible performance. The pilot chosen for this flight was SAAB's test pilot at the time, an Englishmen by the name Robert A. "Bob" Moore. He was a British squadron leader with previous experience flying jets and was thus suitable for the tests. The test flight lasted for half an hour and after a successful landing, Moore stated that "on the ground, it's an ugly duckling, but in the air it's a swift." Like many aircraft which pick up a nickname due to a specific feature or shape, the J29 would fairly quickly receive the nickname "Flygande Tunnan" (The Flying Barrel) or just "Tunnan" (The Barrel) for short. Initially thought of as degrading, the nickname Tunnan would not only become the official name for the aircraft but would also start the SAAB tradition of naming their combat aircraft, a tradition which persists to this day.

After correcting a few production errors the prototype would not only achieve the specified top speed of 1,000 km/h but it would even surpass it, achieving a sustainable speed of 1,060 km/h at one point. The design of the J29 showed a lot of promise for the future and talk of future variants would begin even before production had started. In fact, just a month after the prototype had taken to the air, there was talk of implementing attack-rockets and deflatable internal fuel tanks.

Production of the first J29 variant, the J29A, would commence in 1950 and deliveries to the air force would start in early 1951. It was quickly realized that the internal fuel capacity of the J29A was too limited and work began on implementing the previously discussed internal deflatable fuel tanks. This would be realized in a new version of the J29, designated [[J/A29B|J29B]], which entered production and service in 1953. The J29B's new internal fuel tanks gave it a 50% increase in fuel capacity compared to the J29A. The J29B would be followed by an unarmed reconnaissance version called the S29C which had been planned at an early stage. The S29C was to be followed by the [[J29D]], featuring increased armament and an afterburner, but due to a variety of reasons the J29D never entered production. Instead, a modified version of the J29B, called the J29E, would enter service. The E-variant featured a new dog toothed wing which increased maneuverability at high speeds. The J29E was soon followed by the [[J29F]] which was an upgrade-program for 210 J29B and E aircraft, increasing their performance and allowing them to serve throughout the 1960s.

All in all, 661 J29s would be produced for the Swedish Air Force, the largest production run by SAAB ever. The last of these would serve until the late 1970s.

=== Legacy ===
The J29 was a truly historical wonder for its time. After being stranded for the duration of the war, Sweden managed to not only catch up with modern aircraft development in a short amount of time but it was also able to lead jet fighter development in Europe for the time and arguably even into modern times. The J29 was the first swept-wing jet fighter to be mass-produced in Europe and together with the Soviet [[MiG-15]] and American [[F-86A-5|F-86]] it set the bar for how the next generation of fighter aircraft should be. It was extremely fast for its time and actually managed to take home two closed-circuit world speed records during the mid 1950s.

Besides its international legacy, the J29 was the first Swedish-designed aircraft to see combat. In September 1961, as part of the Congo-crisis, five J29Bs were stationed in the Republic of Congo to contribute to a UN peacekeeping mission (ONUC) in the region. This led to the formation of the air wing F 22 which exclusively served in Congo. F 22 was later reinforced by four more J29Bs and two S29C reconnaissance planes in 1962. F 22 would quickly take air superiority in the area which in turn lead to them primarily performing attack-missions during the conflict. No aircraft were lost during the ONUC despite large amounts of ground fire. When the ONUC was terminated in 1964, the aircraft-type had been decommissioned in Sweden and thus it was decided to only send home a select few J29s to Sweden. The majority of the F 22 J29s were blown up on the spot in Congo when the Swedish left the area.

=== J/A29B ===
Between 1953 and 1955, SAAB would produce and deliver 361 J29Bs to the Swedish air force. These would come to serve in the Swedish air force up until the early 1960s.

As mentioned previously the J29B was fitted with new internal deflatable fuel tanks and these were located in the inner wings. This gave the J29Bs ~50% more fuel than its older brother the J29A. The J29B could also equip two under wing drop tanks weighing up to 600 kg each, which increased the range even further. Interestingly the drop tanks could also be armed as incendiary bombs via a switch box in the cockpit. Beyond drop tanks the aircraft were also capable of carrying a wide variety of rockets for different missions.

Due to delays with the [[A32A]]-development, the J29B would initially serve as an attack aircraft, being designated as the A29B. While rockets were available for the [[J29A]] it was decided to use the J29B as an attack aircraft due to it being a new aircraft type which could be sent directly to the attack wings. There they would stay until 1957 when the A32A finally entered service. Afterwards, they served as regular fighters under the designation J29B.

In Sweden, the J29B would be used until 1963 when the type was ultimately decommissioned due to being obsolete. However a large sum of J29Bs had by this time been upgraded to J29F standards, and these would serve until 1978.

U13732100: Updated upgraded flight performance for realistic mode characteristics

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{Break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} American bomber {{Battle-rating}}. It has been in the game since the start of the Open Beta Test prior to Update 1.27.

The B-17G Flying Fortress, as the name suggests, is intended to be used as a high-altitude level bomber, designed to target enemy airfields and military bases. Despite its large bomb-load, it is not recommended to target moving ground targets such as tank formations. This due to the inaccuracy of bombs being released at high altitude. When using the B-17G, it is always best to group up with others in a wedge-like formation for optimal defence. The higher you climb the harder of a target you will become. A few fighter escorts, such as a squadron of [[P-51D-5|P-51 Mustangs]] would ensure the survival of friendly bombers. Survival is the utmost importance to be remembered when using this plane. While you may miss one target, you can always make another pass once you reload and repair.

* 1 x 12.7 mm M2 Browning machine gun, 2 x beam turrets (600 rpg)
* 2 x 12.7 mm M2 Browning machine guns, tail turret (575 rpg = 1,150 total)

== Usage in battles ==

When facing fighters and interceptors in Realistic Battles, it is best to use Omni-purpose or Armour-piercing/Ground Target ammunition belts for the 12.7 mm M2 Browning machine guns. These ammunition belts are effective at tearing through the engine block and hopefully resulting in an internal engine fire. You may be also able to score a pilot kill on your opponent.

====Specific enemies worth noting====

B-17s are notoriously hard to kill when compared to similar Soviet and German bombers. However, with the B-17 the best defence is to evade your opponent altogether. Your worst enemies will be almost all fighters due to the high BR (FW-190 D, Ta-152, BF-109 G-10/K-4, F8F-1B, Tempest, etc.). Most fighters will have 2-4 cannons which can still make short work of the B-17.
[[File:BomberImage_Boeing_B-17G_2_BG_dropping_bombs.jpg|200px|thumb|right|B-17G dropping bombs in Europe]]
NOTE: The weakest area of approach with the B-17G is the front. Only 1-2 MGs can be focused directly forward if a fighter head-ons you. The crew is also focused at the nose. If there is a fighter at your level, try to turn and expose the tail "barb". Diving may work as well. However, diving can put you into more danger as more fighters may swarm you.

====Counter-tactics====

When climbing to fight the B-17, you will most likely have a lower energy level depending on the plane you use. The F8F-1B, for example, has extremely good acceleration with WEP and can climb ridiculously quickly as well. If in a plane such as an F8F-1B, attempt to head on the B-17 as this is the weakest point. If the B-17 turns away, climb and chase the Flying Fortress at a higher altitude and then dive on it from an angle. '''Always avoid tailing a B-17''', regardless of model. This just warrants a knocked-out pilot or fire.

This slow and lumbering heavy bomber relies entirely on its turrets for defence. Without it, the plane is target practice. Thus "Protective vests" should be the first unlock. Further survivability upgrades will make the fight easier, but do not think it will successfully face-off against enemy fighters. So upgrading the bomb payloads should be second priority. Performance modules can be considered the least necessary.

=== Pros and cons ===


'''Pros:'''

* Large bomb payload
* Powerful air defence capabilities
* Multiple engines
* Overall heavily armoured

'''Cons:'''

* Big target
* Fairly slow
* Nose is extremely vulnerable for the pilot and crew
* Vulnerable to German "Minengeschoße" and >20 mm gunfire
* Engine fires are common
* Wings are big and thus commonly torn off by gunfire
* Aggressive turns may snap wings
* All fuel tanks are located in the wings and are prone to catching fire and damaging/destroying wings
* Can encounter early jets

== History ==

Due to direct experience from U.S. bomber crews in 1943, the B-17F revealed inadequate protection from head-on attacks by enemy fighters. To remedy this problem, a remote-controlled chin turret armed with two 12.7 mm M2 Browning machine guns was introduced on the final production block of Douglas-built B-17Fs, the B-17F-75-DL. This turret became standard on the B-17G, and proved to be more practical than manually operated guns initially fitted to the nose. The B-17G began delivery in September of 1943 and included various upgrades throughout its production. A total of 8,680 aircraft were built from three manufacturers until April of 1945. The B-17G could be considered the cornerstone of U.S. bombing efforts in the European theatre between 1944 and 1945.

=== In-game description ===
The Boeing B-17G Flying Fortress was the first American all-metal heavy bomber. The plane was designed in 1934 in response to a design competition for a coastal anti-ship bomber. A year later the Boeing-299 prototype was built, equipped with four 750-HP Pratt & Whitney engines. It was first flown on June 28 of that year. Subsequent variants used the 1,200 HP Wright Cyclone engines. Boeing factories began mass producing B-17 Flying Fortresses for the US Army Air Corps exactly 12 months later. Throughout the production run, Boeing produced 6,981 B-17s of various variants and an additional 5,745 were built by Lockheed and Douglas giving a total of 12,726 aircraft.

The B-17 quickly became legendary due to its ability to withstand battle damage and to bring hole-ridden aircraft home safely. Nine, and later twelve, Browning .50-cal machine guns offered formidable defensive fire coverage. Nevertheless, the aircraft was not without its faults. For example, the tendency to catch fire was never overcome. Another weakness was the lack of protection against head-on attacks; out of 27 pieces of armor, none protected the crew from the front. Firing a cannon or even a machine gun at the cockpit would find the crew completely unprotected. Another famous part of the B-17 was its highly advanced Norden bombsight, which allowed for effective bomb aiming even at high altitudes.
