Kawasaki-Bell 47G-2/H-13H (ベル47G-2)
The Bell 47 is an American light multirole helicopter that the Japanese bought in 1953. From 1952 to 1965, the Bell 47 helicopters were licensed at the Kawasaki plant. The Japanese armed the Bell 47G-2, which they themselves called the H-13H.
History of Bell 47 in the USA
The Bell 47 was developed by Bell Aircraft Corporation in 1943. It was created from the prototype Bell 30 helicopter. The first prototype took to the air on December 8, 1945, and was adopted by the United States Army in 1946. In 1953, the most popular model, the G version, was created. In this version, the cockpit was modified, the engine was changed, the fuel tanks were changed and the tail boom is completely uncovered.
History of the Bell 47 in Japan
The Japanese Land Self-Defense Force inherited 13 Bell 47D-1 (H-13E) helicopters from the National Safety Agency. JGSDF liked these helicopters very much, so they decided to purchase additional Bell helicopters for reconnaissance purposes, they decided to use the Bell 47G-2 (H-13H) version and immediately purchased licenses for the production of these helicopters at the Kawasaki plant. Between 1957 and 1964, 75 helicopters were delivered to the JGSDF.In 1959, the JGSDF observed that various countries (USSR, USA and others) were modifying helicopters to carry armaments. It was decided that the Bell 47G-2 helicopters should be armed with weapons. In 1960, tests of the H-13H (47G-2) helicopter armed with the M1919 Browning machine gun began, M20 Kai-4 89 mm launchers (super bazook) and unguided FFAR missiles were also assembled. In September 1960, the information was published in the “Aviation Information” magazine.

Work on the development of the armed H-13H continued, but it was very slow. In 1964, the Japanese adopted the Type 64 MAT (ATM-1) missiles, and it was decided to mount them on the H-13H helicopter. The March 1967 issue of Aviation Information magazine features photos of the modified aircraft and information about its general armament. It is hoped that the JGSDF will soon have a fleet of armed helicopters.

Unfortunately, for unknown reasons, the project was discontinued, and the H-13H helicopters were used only as reconnaissance/training helicopters. The last one was withdrawn in 1977.
Structure description
The Bell 47G2 is a three place helicopter (the pilot seats on the left with the two passengers seated side-by-side on the same bench) of standard configuration. It has a two-blade main rotor with a stabilizer bar and a two blade tail rotor. The fuselage consists of three main sections: the cabin, the center frame and the tail boom. The cabin is protected by a “bubble” made of Plexiglas (one of the main characteristic of this model which gives unequalled visibility in all directions), and is accessible from each side through quickly removable doors. A firewall of corrosion resistant alloy is installed between the engine compartment and the cabin area. The center frame, or engine section, consists of a tubular structure of welded steel tubing. This section provides support for the seat, engine and accessories. It is provided with fittings for attachement of the skid type landing gear and provisions for the attachement of float type landing gear. The tail boom, of triangular section, consists of a structure of welded steel tubing. Bolts are used to attach the tail boom to the center frame.A synchronized elevator constructed of aluminum alloy is installed on the tail boom. Its motion is controlled by the fore and aft cyclic control stick. The elevator is attached to the tail boom by means of anti-friction bearing and bolts. The elevator makes cabin load variation less critical and increases maneuverability.A two blade tail rotor is installed on the aft end of the tail boom, and is driven by an auxiliary shaft connected to the free wheeling side of the transmission. The tail rotor blades are constructed of aluminum alloy.An aluminum alloy, tubolar type rotor guard, is installed to protect the tail rotor blades, and acts as a personnel guard.

The armament confirmed by the configuration is 4 Type 64 MAT missiles on a boom. In addition, you can assemble:

  • Browning M1919 machine guns unknown number
  • FFAR Rocket in unknown quantities
  • 89mm M20 Kai-4 (M20A1 Super Bazooka) rocket launcher in unknown number.

It can be assumed that it looked very similar to how the Americans and other countries mounted such weapons on their helicopters. Below are American examples.

The Kawasaki-Bell 47G-2/H-13H would be a very interesting addition to the Japanese helicopter tree. However, it has a few drawbacks: 1. very slow Type 64 shells, 2. unknown amount of remaining armament, 3. very slow. Although these are serious problems, it is almost the last Japanese helicopter to make it into the game (the others are UH-2, OH-1) It would be a very nice premium helicopter for Japan. I encourage you to discuss in the comments and share your own knowledge on this topic.
Finally, I apologize for the linguistic and logical errors because unfortunately English is not my main language and I had to use google translator.

A much better starter helicopter than the one they have now. +1


The worst ATGM in the game paired with what would be the worst helicopter in the game.

I want it.


How low BR can a helicopter possibly be?

the current lowest helicopter br is 7.7

The US tested, several different weapon systems on the H-13 and although pics aren’t so easy to find someone helpfully posted a few together…

I wonder how low a BR a basic Bazooka + MG version could go…?

  1. super bazook + m1919 is br 6 for me
  2. The Japanese H-13H is not the same as the American one H-13H

Re 2 . Thus why I specifically said it was US tests.

Many people are under the impression no Bell 47/H-13 was armed due to MASH ops but there were more varied options if you dig deep enough and more is always better.

This book includes examples of American H-13 weapons

I used to have the book but after many house moves it disappeared in to the dark void. I do however have a 1/35 Revell H-13H gunship stashed away somewhere.

bump, this would add great parity for Japanese Helicopter

This could be a very nice addition for the Japanese helicopter tree. Nothing to break the meta, but a nice alternative to UH-1B nevertheless and should behave like a slightly weaker Alouette II.
In game, it will behave like the Swedish HKP3C, but with slightly worse flight characteristics, 2 less ATGMs and 200m less range for the Type-64 ATGM.

And the ATGM itself is already modeled in-game, so more effort can be put into the helicopter’s chassis model.

Type 64 ATGM performance:

This is why I would much rather see these in the American tree as these armaments were tested on American aircraft.

Some additional armament used by the US

Why not both? Japan could really use additional helis to boost up their tech tree.

And the Kawasaki-Bell with Type-64 ATM could be in Japan, while the US variant could use the US armament variants tested, as has been posted on this forum: Bell H-13: Mighty Mini
