Description

The H8K3 was a prototype variant of the H8K family of flying bombers, being this one the successor to the H8K2, the most produced and praised variant of this family. The H8K3 as mentioned, was a prototype, of which only 2 where ever made. The aircraft had retractable floaters which greatly reduced drag and thus improved top speed, range and fuel efficiency, a retractable dorsal turret, Fowler slaps and sliding hatches replacing the blisters housing the side guns.

It was introduced in Update 1.57 "Battle March". The H8K3 is and should be used as a heavy bomber, but even classified as this, the aircraft is decently fast for its size and features a good climb rate. This combined with its decent defensive armament makes it a hard bomber to engage by fighters and even some interceptors. Still with this, the H8K3 is quite large and can be easily engaged from long distances or hit by AA. This is specially problematic in naval battles because enemy ships AA is more effective. To deal with this you could either engage from really high altitude and drop bombs or engage at low altitude with torpedoes which is more accurate but carries more risk. By using floaters the H8K3 can also capture points by landing on them but this is specially dangerous.

Usage in battles

Describe the tactics of playing in the aircraft, the features of using aircraft 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).

• H8K specific:
  • Decent defensive armament for its rank: 20 mm Type 99 Model 1 Cannon
  • Quite fast for its size and rank
  • Incredible climb rate
  • Decently survivable with armour and self-sealing tanks
• H8K3
  • Improved aerodynamics due retractable landing gear
    • Faster
    • Better climb rate

Cons:

• H8K for Flying boat:
  • Huge target
  • Lack of land-suitable gear
    • Very unreliable to land on regular run-ways
  • Bombs drop in series
• Common Navy plane construction:
  • Poor defensive armament: 20 mm Type 99 Model 1 Cannon

  • Poor defensive armament: 7.7 mm Type 92 MG

History

The H8K3 was a prototype variant of the H8K2. It was modified to allow the dorsal turret and the landing floats to retract, as well as to include fowler flaps, and the blisters which housed the side guns were replaced with sliding hatches. All such changes were made in order to reduce drag and thereby increase speed (Note: None of the turret modifications are currently modeled in game). A total of only 2 were built.
