Description
The Javelin F.(A.W.) Mk.9 is a rank VI British jet fighter
with a battle rating of 8.3 (AB/RB) and 8.7 (SB). It was introduced in Update 1.85 "Supersonic".
General info
Flight Performance
Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.

Survivability and armour
Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.
Armaments
Offensive armament
The Javelin F.(A.W.) Mk.9 is armed with:
- 4 х 30 mm ADEN cannons, wing-mounted (100 rpg = 400 total)
Suspended armament
The Javelin F.(A.W.) Mk.9 can be outfitted with the following ordinance:
- Without load
- 4 х Firestreak air-to-air missiles
Usage in battles
As an aircraft the Javelin has many flaws and has picked up a fairly poor reputation, but once you get used to its quirks you can work around them and the Javelin can become an effective aircraft, which you can do well int. The Javelin's key advantage is its dual after-burning engines which give it good acceleration and very good climb rate, it will (at lower altitudes) accelerate past 600 kph in a 20° climb, without issue. As the Javelin has a fairly poor top speed (at least compared to some of the vehicles you can face), you will want to make use of the powerful engines and climb to a reasonable attitude quickly at the start of the match. In terms of climb profile your options are to either throw the Javelin in to a 10 - 20° climb straight off the runway, or build you speed (up to about 700 kph or so), then enter the same sort of angle climb; the first option will get you to altitude in less distance, but you likely will not have much speed when you get there, on maps with room for it building speed first will give you more options. Your target altitude will vary depending on the situation, but typically you will want to be at at least about 4,000 m, maybe closer to 6,000 m on larger maps. Ultimately if an enemy fighter is above you in the Javelin and decides to dive on you, you're in for a bad time, you will likely not have the speed to out run them in this scenario, and the Javelin's large size and somewhat lacking flight characteristics can make evasion tricky (and lead to you loosing lots of energy); by climbing to a suitable altitude (depending on that the other team are doing) you can minimise the risk of this situation occurring.
Once at altitude you have two main options; you can either take up the role of bomber hunter, or set yourself up in a position to start diving down on enemy aircraft below you. The Javelin fits the role of bomber hunter fairly well, the search and tracking radars can be useful for finding bombers (although they suffer heavily from ground clutter) and the armament of four 30 mm cannons is more than capable of bringing down anything you face with one or two well aimed bursts. The Firestreak missiles also work well against bombers, which often do not have the manoeuvrability to evade them.A benefit of the radar, when coupled with missiles, is that if a target is locked then the locking cone for the missile will automatically follow the target, meaning you do not have to worry about pointing your plane straight at the target to get a missile lock. The Firestreaks can also be used against fighters, however they are not very manoeuvrable missiles so they can often be evaded by fighters fairly easily; they are best used a fairly short range, or if a target is flying in a straight line trying to outrun you.
The main drawbacks of the Javelin are the previously mentioned, low top speed as well as it having terrible energy retention. The idea of turn fighting in the Javelin can be completely forgotten about in most circumstances; the turning circle is not great and attempting it will rapidly kill any speed / energy advantage you once had. Due to its poor energy retention sudden movements in the Javelin should be avoided, where possible make large sweeping turns and gentle control inputs, in some situations even a brief hard rudder input can cost you a not insignificant chunk of speed.
Although the Javelin cannot generally out run enemy on pure speed alone there are cases where you can escape faster aircraft by exploiting the Javelin's excellent climb performance. While many aircraft have a higher top speed than the Javelin, not many can hold speed in a climb quite as well as a Javelin. This works best a low altitude and ideally needs to be done before the enemy can get within firing range. While travelling near your top speed open up the throttles to max and enter a climb; the Javelin will hold its top speed in a 10° climb all day, depending on what is chasing you this may be enough to stop them catching you, if not a 20° climb can be held for some time and even a 30° or more climb can be used for short periods of time if needed. This tactic will not work against all aircraft but many will bleed speed much quicker than the Javelin in a climb (particularly ones approaching 20 degrees) and often start falling behind you leading the the enemy player giving up and finding someone else to engage.
Another annoyance with the Javelin is the gun placement: quite far apart in the wings. The means that you have to take convergence into account and gives you less flexibility in terms of engagement range than nose mounted guns, it also makes head on attacks a very risky proposition.
One more thing to be aware of with the javelin (particularly at higher altitudes) is that once you reach your tops speed you often do not need to use afterburner of even full throttle to maintain it in level flight.Depending on altitude you can maintain a speed near your top speed with 90% throttle or less, this can be useful for saving fuel or cooling the engines (not the latter is necessary most of the time), if you don't want maxed out speed even a throttle setting as low as 75% can maintain a decent cruising speed).
Radars
The Javelin F.(A.W.) Mk.9 is equipped with an AN/APS-21 search radar, as well as an AN/APG-26 target tracking radar. Both radars are located in the nose of the aircraft.

Modules
You are going to want to focus on getting flight performance modifications first to make the Javelin more bearable to fly. The stock belts and ADEN cannons are very good so these upgrades can be left until last, the stock roll rate is also good so new boosters are not a necessity and you may wish to go for higher rank engine upgrades first. The Firestreaks come down to personal preference; if you like missile game-play then they can be effective, but they are far from the best missiles available in game. If you have never played with air to air missiles before or can't stand the stock offensive capabilities then you may with to unlock them, but do not expect to be shooting down fighters in the middle of a dog fight with them. Learning when / where to use them, and in what circumstances they are likely to hit will take time.

Pros and cons
Pros:
- More manoeuvrable than some other jets and has very good roll rate
- Effective air to air missiles
- Good acceleration
- Is equipped with the AN/APS-21 target detection radar, with the best range of any airborne radar in the game; as well having an AN/APG-26 tracking radar.
- Can use afterburner (WEP) for very long periods of time without overheating engines
Cons:
- Relatively low top speed
- Big target
- Pulling negative G cuts out engines due to fuel starvation
- Convergence is important (guns are far apart)
- Extremely poor energy retention
- Anything more than slight damage to wings causes massive loss in speed and lift
- Can push past its wing break speed at sea level while at 100% throttle
History
On 13 April 1949, the Ministry of Supply issued instructions to two aircraft manufacturers, Gloster and de Havilland, to each construct four airworthy prototypes of their competing designs to meet the requirement, as well as one airframe each for structural testing. These prototype aircraft were the Gloster GA.5, designed by Richard Walker, and the de Havilland DH.110, the latter of which held the advantage of also being under consideration for the Royal Navy.

Excellent additions to the article would be video guides, screenshots from the game, and photos.
