== General info ==

With similar performances to the AIM-9B, the FGW.2 should be treated the same way. The missile's performance is generally sub-par in comparison to other missiles found around 9.0 to 10.7, thanks to the FGW.2 basing having stats of a missile designed in 1954-6. With only 10G's of overload and a tracking rate of 11°/s, it performs terribly in high-G dogfights. The missile will be ready to fire in 1 second, while the target search time amounts to 20 seconds.

The AIM-9B FGW.2 is known also as the AIM-9F, an upgrade to the AIM-9B. The differences between the E and F variants are a different design philosophy including a slightly different sensor window, solid state electronics instead of vacuum tubes, and a new cooling system.

=== Effective damage ===


For being relatively bad compared to other missiles, the FGW.2 does not disappoint in the damage department. Like every other AAM, if this missile connects, it will knock out or at least deal critical damage to any aircraft. Obviously, it can't be used against ground targets, unless you count parked and active aircraft.

=== Comparison with analogues ===

Its performance is identical to the [[AIM-9B Sidewinder|AIM-9B]] and [[R-3S|R-3]] missiles, but is massively outperformed by mid-tier missiles like the [[AIM-9D Sidewinder|AIM-9D]], [[AIM-9E Sidewinder|E]], [[R-60]], and [[Matra R550 Magic 1|R550]]. Its lack of a movable seeker-head, higher G-pulling, range, and sensitivity make it subpar if not for having four missiles on a platform that is capable of traveling at Mach 2.

== Usage in battles ==


This missile's best usage comes in three situations, low energy, roll-rate spamming and compressed enemies:

* Enemies at low energy can't dodge this missile, as their planes won't be able to manoeuvre above 10Gs.
* Enemies that constantly roll in order to dodge your guns will find the missile to be much more accurate, as their aileron rolls put them in a situation where they can't run.
* Enemies that have high compression speeds will find your missiles hard to dodge as well. The [[Vautour IIA IDF/AF (France)|French Vautour bombers]], high speed [[MiG-15 (Family)|MiG-15]]'s and [[Yak-38]]/[[Yak-38M|38M]], and [[F11F-1]]'s won't be able to outturn the missile's seeker at high speeds, and will be forced to either bleed enough speed to manoeuvre or get hit by the warhead. It has a top speed of around Mach 1.7, so the planes that can outrun this missile with low manoeuvrability are other [[F-104 (Family)|F-104]]'s.

Forcing enemies to bleed speed is more of this missile's job, but speed isn't generally a big deal for the jets it can be equipped on, so it's kind of redundant.

=== Pros and cons ===


'''Pros:'''

* Effective against low-energy targets
* Decent at longer ranges in a straight line
* Effective against aircraft with low manoeuvrability
* Effective against aircraft in their high-speed compression ranges
* Only available on a platform that benefits from its more passive role

'''Cons:'''

* Small seeker area
* Short range relative to other AAMs
* Poor manoeuvrability limits its capability in top-rank dogfights

== History ==

===Development===
The missile's history starts at the Naval Ordnance Test Station (NOTS) at China Lake in 1947.<ref name="Goebel2019">Goebel 2019</ref> Under William B. McLean, the missile conception sprang from mating lead-sulfide proximity fuzes that were sensitive to infrared radiation with a guidance system to home onto the infrared source.<ref name="HollwayFOX2">Hollway</ref> Initially his own private project, McLean eventually received approval by Admiral William S. Parsons for development.<ref name="Goebel2019" />These missiles were first test fired in 1951, with the first air-to-air hit was made on 11 September 1953 on a drone.<ref name="ParschAIM9">Parsch 2008</ref> This experimental missile would be designated as the ''XAAM-N-7''. The missile would also earn the name "Sidewinder" by the development team, named after the desert rattlesnake that senses its prey's heat and moves in a winding motion.<ref name="Goebel2019" /><ref name="HollwayFOX2" />

Initially a US Navy project, the US Air Force was urged into participating by Howard Wilcox, the next project lead after McLean was promoted to upper management at NOTS in 1954.<ref name="Goebel2019" /> This culminated in a shoot-off in June 1955 between the Navy's Sidewinder against the Air Force's GAR-2 Falcon missile. The Sidewinder's performance in this event resulted in the US Air Force putting their support in the Sidewinder.<ref name="ParschAIM9" /> By May 1956, the missile was officially adopted as the ''AAM-N-7'' for the US Navy and the ''GAR-8'' for the US Air Force.<ref name="ParschAIM9" /><ref name="GervasiArsenal">Gervasi 1984, p.256</ref> These designation would remain until 27 June 1963, when the Sidewinder's designations were standardised across all armed services as the '''AIM-9'''.<ref name="ParschDesignation">Parsch 2020</ref>

===AIM-9B FGW.2===
The '''AIM-9B''' (pre-1963 Navy designation ''AAM-N-7 Sidewinder IA'') was the initial production version of the Sidewinder.<ref name="ParschAIM9" /> More than 80,000 units of the AIM-9B Sidewinder would be produced.<ref name="GervasiArsenal" />

The Sidewinder was also acquired by NATO forces for their air forces. The AIM-9B licensed production was distributed to West Germany, who would produce 15,000 units.<ref name="GervasiArsenal" /> Like the US Navy and US Air Force, the manufacturer sought to improve the AIM-9B design. These improvements modernized the components with solid-state technology, added a carbon dioxide cooling for the seeker, developed a new nose dome and implemented better optical filtering.<ref name="KoppAUSAIM9">Kopp 2014</ref> The culminations of these improvements developed into the '''AIM-9B FGW.2''', which is also known as the ''AIM-9F'' in US nomenclature.<ref name="ParschAIM9" /> These missiles would see service in 1969, with conversions being done on European AIM-9B with the FGW.2 upgrade.<ref name="GervasiArsenal" /><ref name="ParschAIM9" />

Wyvern S4

U7965774: Added a "Con"

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a gift rank {{Specs|rank}} British fighter {{Battle-rating}}. It was introduced in [[Update 1.59 "Flaming Arrows"]].

The {{PAGENAME}} can carry great amounts of payload due to its distinctive feature, the turboprop powerplant. This engine enables it to exceed 600 kph in level flight.

The Wyvern is an aircraft that can carry a large payload so it can be used in the strike fighter role. One of its most popular payloads, 16 x RP-3 , enables it to destroy a large amounts of targets with medium armour like light pillboxes and up to heavy tanks. The Wyvern is also a strong fighter, below 3,000 m. As the Wyvern does not have a compressor of any sorts, engine power drops significantly above 3,000 m. Keeping altitude at 3,000 and doing Boom & Zoom or Boom & Run attacks are of the most successful fighting doctrines. Although the Boom & Zoom attack will most likely bleed the Wyvern's speed very quickly, employing Boom & Run instead of this attack is recommended when possible.

The Wyvern S4, being a turboprop, is an exceptionally fast aircraft for its battle rating. Though a prop aircraft, the Wyvern functions very similar to jet aircraft in play style, due to the nature of its weight and engine.

At sea level, where the engine functions at maximum capacity, the Wyvern is almost uncatchable. Being able to maintain nearly 640 km/h in level flight without a payload, even enemies diving on the Wyvern will have trouble catching up, and will quickly fall behind as they lose energy. This is the strength that any pilot of the Wyvern should always exploit, by employing Boom & Run tactics on enemies. With four Mk V Hispano cannons, and a staggeringly large ammo reserve, the Wyvern is more than equipped to quickly dispatch any aircraft that end up in front of it.

Though the Wyvern does have an above average climb rate due to its powerful engine, it functions best near sea level. The pilot should only take the plane up to a maximum of a couple thousand meters, unless bomber hunting, and use the Wyvern's excellent acceleration and top speed to quickly annihilate any enemies who end up on low altitude. The Wyvern can also use this speed to bait enemies, who see the Wyvern as an easy target, down to low altitudes. This will allow allied fighters to easily establish high altitude air superiority, which can often end up in victory by itself, without the Wyvern pilot actually putting himself in any great danger.

Speed, climb rate, and armament are the Wyvern's only real method of taking out enemy aircraft. Though it can go incredibly fast, this is solely due to the aircraft's powerful turboprop engine. Coming in at a heavy 7 tonnes with no payload, or 9 and a half tonnes with its maximum payload, the Wyvern's speed suffers when performing any maneuver bar going in a straight line. Even minor adjustments will cause the fighter to bleed speed at an alarming rate, with full-out turns able to halve the aircraft's speed before it has even completed a 180. Whilst it has the speed, the Wyvern can turn very fast but as mentioned it will lose this speed in the turn very quickly. Unless absolutely necessary, avoid performing any but the most gentle of maneuvers in this 7 tonne beast.

This focus on simply flying straight is further amplified by the turboprop's ability, or lack thereof, to quickly react to input changes. As happens in jet aircraft, the turboprop engine found on the Wyvern will take a fairly long amount of time to react to changes to the throttle meaning the Wyvern pilot will struggle to regain speed if the throttle is dropped at any point, such as to recover from a vertical stall maneuver.

== Usage in battles ==

As a gift aircraft, the Wyvern's main role in a player's lineup will usually be to grind Silver Lions and Research Points. With its wide variety of secondary armaments, the Wyvern is one of the best aircraft available to the British for this purpose. Typically, load up three 1000 lb bombs, and use them to fully destroy one bombing point. The Wyvern is taken to its maximum weight whilst carrying this payload, and will only be able to maintain around 550 km/h at sea level, so the pilot should attempt to drop the bombs as soon as he can, to regain the Wyvern's 640 km/h top speed. Using the four Mk V Hispano cannons, preferably with Air Targets ammunition loaded, employ the Wyvern as was detailed in the above section, as a boom-and-zoom aircraft at low altitude. If one had experience flyingany jet aircraft in the past, use the Wyvern exactly as a jet. Do not turn for anyone, if a pass misses then continue onward until a great distance is gained, ''then'' turn around for another guns run.

While fighting, any pilot should refrain from turn fighting and perform energy fighting whenever possible

In Ground Forces, the pilot has the choice between using three 500 lb bombs, three 1000 lb bombs, sixteen RP-3 rockets, or sixteen AP Mk I rockets. With such an armament, the Wyvern's distinctive engine sound can signal in the incoming doom of any tank unfortunate enough to end up in the pilot's vision.

== History ==

The Wyvern was one of the only turboprop aircraft ever fully developed, and entered service long after World War II had ended. The design was a relic of an era past, with jet-powered aircraft now entering. The aircraft also suffered from a long development period, beginning in 1944 as the P.10. This lead to the Wyvern seeing very little combat use and being quickly retired. The Wyvern S.4 variant contained an Armstrong Siddeley Python 3 turboprop engine, able to output 3670 horsepower, and was the first and only variant of the Wyvern to enter service with the British Royal Navy.

Plagued with various engine problems during its brief period in service, the Wyvern S.4 only saw actual combat in late 1956 during the Suez Crisis, racking up 79 sorties and 2 losses, and was retired soon after in 1958. This marked the Wyvern as the only British turboprop to ever see combat.<ref>http://www.militaryfactory.com/aircraft/detail.asp?aircraft_id=1482</ref>

A2D-1

2020-07-04T16:48:42Z

U7965774: Spelling corrections, "Con" addition.

{{Specs-Card

}}

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a premium rank {{Specs|rank}} American attacker {{Battle-rating}}. It was introduced in [[Update 1.89 "Imperial Navy"]].

The {{PAGENAME}} was outfitted with the Allison XT40A turboprop engine, effectively doubling the horsepower over the [[AD-2|AD-2 ''Skyraider'']], however, installation of contra-rotating propellers was needed to harness all of that power. To accommodate this new thrust, the wing roots were decreased in their thickness while the tail section became larger and taller in order to stabilize the aircraft when under power. With the new engine situated, it was time to focus on the armament of the aircraft. Basic offensive 20 mm cannons were implemented, placing two in each wing with each gun being loaded with 400 rounds of ammunition, twice the firepower as on the Skyraider!

The Douglas {{PAGENAME}} did not have the same legacy as the A-1 Skyraider, however here in War Thunder new life has been given to this hybrid turbo-prop fighter allowing it to find a niche as an attacker turned fighter and/or bomber, all depending on the ordnance outfitted by the pilot. Not to be underestimated, though having a bulky airframe, the {{PAGENAME}} has the speed and ordnance which can help in turning the tide of a battle. Often this aircraft will come up against jet aircraft, but its lack of speed can be made up in manoeuvrability and skill of the pilot in command.

== General info ==
=== Flight performance ===

'''5500 shaft horsepower''' (!sic) — Let this sink in for a moment. Nigh triple that of the another contra-rotating propeller machine in the game, the [[Seafire FR 47|Seafire Mk.47]] - queen of the Spitfires. Furthermore looking at the statistics, one sees more to be gay about. The top speed rivals early jets, rate of climb is phenomenal and the short take off run speaks for a great acceleration. Every characteristic tells the tale of a great [[energy fighting]] machine. This [[:Category:Attackers|attacker]] is very much unlike its older cousin the [[AD-2|AD-2 ''Skyraider'']].

But the devil is in the detail. The wing loading is exceptional high >220 kg/m², sitting even above the [[P-47 (Family)|P-47 ''Thunderbolt'']]. It further does so in category of weight and size. Make no mistake, the Skyshark is a Sky''whale'' and flies appropriately at times. Due the weight, the elevator authority feels weak amd one will kiss the ground more than once, before learning to fly with the momentum properly. Rapid pitch changes are not the Skysharks forte, an abusable fact known to aces. Worse still is the jittery behaviour while maneuvering or taking aim. Again the aircraft<nowiki>'</nowiki>s mass will delay any inputs, especially noticeable in [[Simulator Battles|simulator mode]]. Another quirk is the engine itself: As a turboprop the jets require a spool-up time when going from low to high power.

Of course one wants to exploit the A2D ''Skysharks''' advantages. From above we can notice a plane much simuilar to it: The [[P-47M-1-RE|P-47M ''Thunderbolt'']]. However, in one thing they are apart: Their climb rate, the Bolt<nowiki>'</nowiki>s Achilles heel. Further the acceleration is better, thanks to the 5500 shaft-hp allowing for a better sustained turn rate despite mediocre maneuverbility. This allows the A2D to outshine many early jets in turn dogfights. Maintaining a Yo-Yo with 350 km/h IAS is possible and sadly necessary, any slower than this and the aircraft becomes less responsive. A rare case were lower speeds reduce overall controllability. Again the max weight rears its ugly head.

=== Survivability and armour ===


The A2D1 has no protection for the Pilot which makes it very vulnerable to AAA and other Aircraft. The radar is also vulnerable. Belly landings normally result in the tail being ripped off and the aircraft breaking the wings. The engines perform well even when damaged and can fly with one heavily damaged and one operational. Rolling with negative G<nowiki>'</nowiki>s can rip the wings off. Fires can be quite common.

== Armaments ==
=== Offensive armament ===

{{main|T31 (20 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 4 x 20 mm T31 cannons, wing-mounted (200 rpg = 800 total)

The T31 is a modification of the Hispano-Suiza system and an improvement from the AN-M2 cannon, mostly in weight though. The quadrupple punch is a welcomed upgrade from the Skyraiders. However as the autocannons are mounted in the wings, the pilot must be cognizant of their range to the target and their convergence setting to ensure the ammunition hits the target and doesn’t just fly on by.
=== Suspended armament ===

{{main|AN-M57 (250 lb)|AN-M64A1 (500 lb)|AN-M65A1 (1,000 lb)|AN-M66A2 (2,000 lb)}}
{{main|HVAR|Mk.13/44}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* Without load
* 20 x 250 lb AN-M57 bombs (5,000 lb total)
* 20 x HVAR rockets
* 10 x 500 lb AN-M64A1 bombs (5,000 lb total)
* 2 x 1,000 lb AN-M65A1 bombs (2,000 lb total)
* 2 x 2,000 lb AN-M66A2 bombs (4,000 lb total)
* 2 x 2,000 lb AN-M66A2 bombs + 8 x 500 lb AN-M64A1 bombs (8,000 lb total)
* 2 x 2,000 lb AN-M66A2 bombs + 20 x HVAR rockets (4,000 lb total)
* 2 x Mk.13/44 torpedoes

Twenty-two total hardpoints allow the {{PAGENAME}} to carry an abundance of suspended ordnance much like the Skyraider. Choices of bombs, rockets and torpedoes open up the possibility of targets which can be engaged. Choices in bombs provide options with either 250 lb, 500 lb, 1,000 lb and 2,000 lb bombs. With these targets can range from mobile light trucks, anti-aircraft artillery, tanks, pillboxes and even bases. HVAR rockets provide flexibility to allow the {{PAGENAME}} to fire them from any angle (a restriction which bombs have) as the aircraft descends towards the target. The Mk.13/44 torpedoes are outfitted with a special frangible wooden drag ring and box stabilizer which allow for the torpedo to be dropped at high speeds and from higher altitudes than unmodified torpedoes making them a perfect option for the {{PAGENAME}} when taking on an anti-shipping role.
== Usage in battles ==

In [[Arcade Battles|Arcade]] and [[Realistic Battles]], the A2D-1 can climb with no extra armament to become top cover for the allied fighters, or alternatively escort bombers to their designation. It can also carry one of its most hard hitting armaments and destroy several ground targets or destroy two bases. Though in [[Simulator Battles]] the jittery controls and lack of control make it more akin to a [[B-57B]] fast jet bomber.

;''Dogfights''

With its outstanding acceleration and climb-rate the Skyshark can safely assault hostile ground forces and then decide to join the fray, by either assault climbing the closest hostile, relying on its acceleration to gain an energy advantage mid dogfight, or return to allied fighter pack to rejoin their climb. Going straight for the climb from the start will put the A2D at an immense energy advantage should the fight start.

Preferred combat styles are [[energy fighting]], due its aforementioned acceleration and climb-rate, but also [[BnZ|Boom and Zoom]] for the Skyshark is a heavy weight, note though it can easily reach its terminal velocity and loose all wings, coupled with the slow spool-up-time of the engine from low power, a provident engine and air-brake control is paramount! The G-Suit is a welcomed addition, but will often lead to ripped wings via g-forces in diving maneuvers.

Combat versus Jets differs amusingly little than versus propeller crafts. After easily gaining an altitude advantage, dive on the hostile and force it to break away (turn), hence losing speed and energy. Three things could happen now.

# the enemy jet dives - do not try follow too long, your terminal speed is lesser than most jets -> regain altitude,
# the enemy jet runs - hostile didn't lose too much speed, or assumes the A2D<nowiki>'</nowiki>s speed and acceleration to be lesser. If it is the latter -> outpace and kill it,
# the enemy jet breaks more - hostile is either trying to force an overshoot or prepares for a dogfight, either way -> engage in manoeuvre combat.

Versus propeller fighters one should engage in turnfights, otherwise the Skyshark is most dominant against most WW2 fighters. Few Rank 4 fighters can challenge the A2D on equal terms, so stay sharp.

;''Strafing''

The A2D-1 can be a very valuable asset to teams looking to win by destroying ground troops or assaulting the airfield.
However the Skyshark is so heavy weight and hence slugish that every strafing attempt is an inch away from a crash. The momentum change comes later than expected and is more akin to a medium bomber like the [[B-25J-20|B-25]]. One is not surprised the US Navy stuck with the older AD-2, as in the ground attacker role the Skyshark must play a slow game. Take time for every attack run and try to maintain a speed way above 300 km/h IAS with combat flaps. This is a very high velocity for strafing runs, however any less and the plane will not rise above the newly explosive laden ground...

===Radars===
{{main|AN/APS-19}}
The A2D-1 is equipped with an [[AN/APS-19]] search and tracking radar. The radar is mounted in nose, inside the propeller hub.

== History ==

The Douglas A-1 Skyraider was an impressive aircraft for a piston-driven propeller-powered aircraft which survived into the jet age, being used by the United States Navy, Marine Corps and Air Force and around nine other countries over its 40-year service. Like many aircraft which were successful, they went through many iterations and variants to keep them up to date with new requirements and technology as they came about. In an age where jet aircraft were beginning to overtake propeller-driven aircraft in all aspects of military service, the Bureau of Aeronautics which was the U.S. Navy’s material-support organization was looking for a suitable option for an attack aircraft which would be more fuel-efficient than the upcoming jet fighters. To meet the Navy’s requirement, Douglas Aircraft looked to their AD Skyraider airframe and considered modifying it to accept a more fuel economical turboprop engine.

In the early years following the war, jet engines underwent rapid development. This attracted the interest of the US Navy, which sought to arm itself with aircraft that were superior to that of potential opponents in speed, altitude, payload, and flight range.

As it turned out, jet engines were perfect for fighter aircraft but too “voracious” for strike aircraft, as they significantly reduced their range. The best engineering solution was to introduce the turboprop engine, which was a task the Douglas company undertook.

Initially, engineers simply wanted to replace the piston engine of the Skyraider attack aircraft with a turboprop engine. However, this led nowhere and the vehicle required significant modification. In the end, the engineers settled on a prototype with Allison Т-40А-2 turboprop engines and coaxial propellers.

The first flight of the XA2D-1 prototype, called the Skyshark, took place on May 26, 1950, but engine vibration nearly destroyed the aircraft and it was forced to land after only two minutes. By December 1950, the prototype had already completed over a dozen flights. However, a routine flight on December 19, 1950, ended in tragedy. Due to issues with the engine, the vehicle and pilot crashed. Nevertheless, testing continued and, despite the many technical problems that plagued the aircraft, the army ordered 10 pre-production models of the A2D-1. However, on August 5, 1954, another accident occurred when the main gearbox failed, and the aircraft crashed a short distance outside Los Angeles. This time, the pilot managed to escape the aircraft, but the project was closed and it was decided to dismantle any existing prototypes. Apparently, this decision was influenced by the fact that in the same year for the first time Douglas got another project in the air, this later became the famous A4D Skyhawk - a new generation of jets.

=== In-game description ===
In developing this aircraft, the Bell designers came up against two global problems. The first was that the P-39 was intended for export, and there was no way around this. The impossibility of fitting a turbo compressor to the low-altitude Allison engine (for fully explicable reasons) was one reason why the aircraft was never able to achieve a worthy place in the US air forces. The nature of air combat, both in Europe and the Far East, prevented the P-39 from making use of its advantages, while it was not possible to rectify its main drawback - its poor high-speed performance - because of the ban on exporting turbo compressors outside the USA.

The second global problem was connected to a technical failure in the production of the 20 mm Hispano-Suiza AN-M1/M2C cannon by the Bendix company. This was the first problem the Bell specialists tried to tackle. The Bell specialists initially tried to solve this problem themselves. The virtually unusable 20 mm cannon was replaced by the old, heavy but more reliable Colt-Browning M4. The cannon had a lot of faults, mainly its low rate of fire and extremely inadequate stock of ammunition - only 30 shells. On the other hand, in spite of its weight, it could easily be fitted in the front part of the Cobra's fuselage; furthermore, it has one incomparable advantage over the Bendix product - it actually fired.

It must be noted that the M1 cannon was not always fitted onto the first series of the P-39, you could find the M4 here and there. Only the Model 26 (P-39G) carried the M4 as standard equipment. However, it did not go into production, but became the founder of a whole number of virtually identical series from P-39K to P-39Q. The main units were borrowed from the quite promising P-39D-2 series.

The P39K differed from the earlier models in its engine, the Allison V-1710-63, which was successfully tested in that same D-2. It was fitted with an afterburner system. It developed a nominal power of 1352 h.p. and 1550 h.p. in WEP (War Emergency Power) mode. The K series was the only one fitted with such an engine along with a three-bladed Aeroprop propeller. It was a full 360 kg heavier than the D-2, although externally, apart from the propeller, there was no visible difference. In fact, the extra weight was due to additional armor plating, which was used beginning with the K and on all subsequent series.

Altogether, by August 1941, 210 examples of the series K-1-BE, K-2-BE and K-5-BE, which were virtually identical, were built. Forty of them were sent to the USSR.
