This page is about the Swedish jet fighter J28B. For other version, see Vampire FB 5.

Description

The J28B is a rank V Swedish jet fighter with a battle rating of 7.7 (AB/SB) and 7.3 (RB). It was introduced in Update 1.95 "Northern Wind".

The J28B is a early war jet known as the Vampire FB 5 in the British tech tree. It was ordered in large numbers by the Swedish air force to take a leap into the jet age. The Vampire family is known for its great dogfightning capabilities, meaning the J28B can comfortably fend off several opponents at once if controlled by a skillful pilot. This aerial performace is given at the cost of engine power.

General info

Flight performance

The J28B performs well at low altitude where it easily outturns most opponents it faces. Thanks to excellent flaps and air brakes, a pilot aware of his/her energy can fend off anyone that picks a fight. The flaps can be utilized at various speeds to outturn any enemy at any time. It is generally dogfights that the vampire platform shines. Although the power is lackluster, a pilot aware of his surroundings and enemies will have no difficulty avoiding incoming enemies. This lack of engine power will however cripple the J28B when it comes to accelleration. A vampire tends to loose a lot of speed when engaged in turning. So gaining it back to defend itself from new targets becomes a hassle. And even if a J28B pilot manages to get his/her speed up, catching a target will be close to impossible with a slow top speed. This lack in power hinders the vampire in many ways, mostly related to energy. This is why "vamp" pilots are adviced to climb at the beginning of a match, despite the lack of a decent climb rate.

The J28B performs identical to the Vampire FB 5 which should not come as a surprise. The fire power is what makes them different however. The J28B is outfitted with the Swedish Akan m/47B (short for "Automatkanon"), which is the Swedish designation of the British hispano mk.V, although Even though the caliber and fire rate is the same, the burst mass is larger. This has to do with the Swedish ammunition. The Swedish ammo type contains more TNT and is fully tracer equipped, meaning stealth isn't a option. Despite this downside the guns perform closer to the american AN/M3 guns instead of the british Hispanos, making the J28B the most effective vampire in regards to shooting. The J28B is also outfitted with several types of anti tank and ship rockets. Despite lacking the large 1000lb bombs the FB 5 offers, the rockets offers a much different experience compared to the original model. The rockets fire one at a time held on by a Swedish rocket rack, pointing them further down than usual. The average pilot, especially the ones coming from the FB 5, will find this new placement tricky to get used to. But concidering the single fire system, a skilled pilot might be able to rank up more kills in tank battles compared to the FB 5.

Survivability and armour

  • 38 mm Bulletproof glass - Armored windscreen
  • 12.7 mm Steel - Armor plate behind the pilot's head
  • 3 mm Steel - Armor plate under the engine

The J28B has the same armour as the Vampire FB 5 as well as the Italian Vampire FB 52A. Despite being deadly in a headon due to the beefed up guns, A vampire should never fully commit to a headon engagement, the bulletproof glass will however, save the pilot most of the time. The tail section is not easily saved though. The twin boom makes it twice as likely to hit the traction of control surfaces. This leaves the J28B completely useless usually resulting in abandonment of the aircraft, which should be avoided at all costs.

Armaments

Offensive armament

Main article: Akan m/47B (20 mm)

The J28B is armed with:

  • 4 x 20 mm Akan m/47B autocannons (150 RPG - 600 rounds total)

Suspended armament

Main articles: m/49A, m/51, m/49

The J28B can be outfitted with the following suspended ordnance:

  • Without load
  • 8 x m/49A unguided rockets
  • 8 x m/51 unguided rockets
  • 4 x m/49 unguided rockets

Usage in battles

Describe the tactics of playing in an aircraft, the features of using vehicles in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

  • Great turning and dogfighting capabilities.
  • Stronger guns than the British/Italian counterpart.
  • Effective air-brakes that generate lift once deployed.
  • Decent ammo count.
  • Easy to land.

Cons:

  • Slow top speed.
  • Poor rate of climb.
  • Low gun placement forcing pilots to aim higher than usual.
  • Weak tail section that often suffers damage from enemy fire.

History

Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

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