The Shinden has a maximum speed of 750 km/h (466 mph), making it quite fast and allowing for steeper dives; however, its turning rate is very slow, making it a very ineffective dogfighter.

The J7W1 Shinden has a maximum speed of 892km/h, 558mph, 485kias (this is Vne speed - the absolute maximum speed). In a dive from service ceiling, a speed of mach 0.9 has been recorded and is sustained until IAS speed limit is reached. The aircraft can handle a max load of 11g and compresses rudder, pitch and roll at extremely high IAS speed in order of descending effect.

Description

The J7W1 Shinden is a bomber interceptor designed to make quick work of raiding bomber aircraft. It has exceptional performance at altitude, more than exceptional aramament and a decent climb rate. Double the weight of a fully loaded A6M, and definitely heaps faster to make up for it. This aircraft thrives with boom and zoom, and has a great energy retention at speed due to sleak aerodynamics. Inherently less stable than a normal tail plane thanks to a rear mounted engine push thrust configuration canard design, it is known for rapid pitch angle changes, great roll rate and less drag, by design. The flap system does not work in game currently however it enhances negative G two fold, at the cost of your speed. The aircraft is very prone to fires however, a single hit to the fuel tanks will result in an inextinguishable flame that will for sure be your demise.

The J7W1 Shinden is a Rank IV Japanese fighter with a battle rating of 5.7 (AB/SB) and 6.0 (RB). This aircraft was introduced in Update 1.43.

General info

Flight Performance

The J7W1 Shinden has a maximum speed of 892km/h, 558mph, 485kias (this is Vne speed - the absolute maximum speed). In a dive from service ceiling, a speed of mach 0.9 has been recorded and is sustained until IAS speed limit is reached. The aircraft can handle a max load of 11g and compresses rudder, pitch and roll at extremely high IAS speed in order of descending effect.

Survivability and armour

Very prone to fires, and difficult to extinguish. Armor glass (70mm) in front of pilot and steel armor plate (17mm) in front of pilot in between guns. Engine snipes common, due to the position of the engine. Wing tip damage can increase likelyhood of unrecoverable flat spins.

Armaments

Offensive armament

Main article: Type 5 navy (30 mm)

The J7W1 is armed with:

  • 4 x 30 mm Type 5 navy cannons (60 rpg = 240 total)
  • Shells: HEF-T, PT, P: 910m/s muzzle velocity
  • Shells: HEF-I, HEF: 720m/s muzzle velocity
  • Tracer: 910m/s
  • All other belts: Mixed shell velocities, see above.

Suspended armament

The J7W1 can be outfitted with the following ordinance:

  • Without load
  • 2 x 60 kg Navy Type 97 Number 6 bombs (120 kg total)
  • 4 x 60 kg Navy Type 97 Number 6 bombs (240 kg total)

Usage in battles

The Shinden is armed with 4 30 mm frontal cannons, making it quite the slugger. Due to its slow turn time, it is usually best for the pilot to engage enemy fighters head-on, or from above and behind since usually, a single burst of shots can easily knock even heavy bombers out of the sky. Regarding fire from bomber gunners and head on engagements, the plane's armour enables it to take some beating to the wings, but the pilot is heavily exposed from the front. Should this plane be forced into a turning fight, it will almost certainly lose since its BR means it will face up against faster-turning Spitfires and P-51Ds. Its speed might be used to its advantage in order to retreat or gain some distance before attempting to initiate head-on combat.

Pros and cons

Pros:

  • Pilot has some protection in the back from the engine.
  • competetive high speed turn rate
  • Good roll rate
  • Amazing pitch response
  • 4x 30 mm cannons make for some great offensive firepower.
  • Great high speed and handling and dive.
  • Since the engine and propeller are located in the rear, it is not likely to take damage or catch fire from shots landing at its front.

Cons:

  • Slow sustained turn rate.
  • High speed rudder suffers some compression
  • Pilot more exposed at the front.
  • Since the engine is located in the rear, it is especially vulnerable to enemies behind it.
  • Shots to the front may damage its "tail" flaps.
  • Armament may detonate
  • Fuel tanks are easily flammable and do not self seal fully.

History

The J7W1 Shinden (震電, "Magnificent Lightning") was an Imperial Japanese fighter of WWII that was built near the end of the war in an attempted response to the American B-29 Superfortress bombers. The aircraft used a canard wing formation, (canard wing formation refers to how the main wings are mounted at the rear of the fuselage and smaller wings are placed at the front. Similar to the Curtiss-Wright XP-55 Ascender.) Like the Ascender, the J7W1 was never put into mass-production and was abandoned while still in the prototype stage.[1]

Developed with the intention of intercepting heavy bombers, it was given 4 nose-mounted 30 mm cannons.

Development of the aircraft began in 1944, but shortages of manufacturing supplies continued to delay its development and testing and the first prototype wasn't completed until April 1945. The Navy placed high hopes in the new model and it was originally hoped that the Kyushu's Zasshonokuma factory and Nakajima's Handa plant would be able to produce over a thousand of the aircraft by 1947.

The prototype first flew on 3 August 1945 from Itazuke Air Base. The plane flew a total of three times, each time as a test flight before it was grounded permanently due to the Japanese surrender and end of the war.

Various parts of the Shinden survived the end of the war and its fuselage can be seen at the National Air and Space Museum in Washington DC.[2]

Media

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