IPaul72: NC-27 Otsu-Gata Sensha
A little history
The NC-27 Otsu-Gata Sensha also known in the western world as the Char NC1 was in essence a French tank. Build by the French for direct export but not used by the French army. It was supplied to such countries as Yugoslavia, Japan, Netherlands, Belgium, Sweden and other countries. It main place was set to derivative of the FT-17 which had been around since 1917. Mainly most of the tanks were to be built for export and sold to other nations. They was used for trials and proved to be unsuccessful for various reasons. Just to list a few the original engine, clutch and gearbox of the NC-27 was too weak for the tasks it was set and suffered constant reliability issues.
So when it was sold to Japan in 1929 they set about upgrading it.
Some other modifications were:
• The changing of the Renault engine (65hp) to a Mitsubishi diesel engine (75hp) Diesel is harder to ignite so therefore minimised engine fires upon round impact.
• 37mm French cannon removed and a 57mm installed.
• Increase in armor along the vehicle as current armor upon delivery of the vehicle was found to be inadequate.
They found these modifications transformed the vehicle and it became an inspirational vehicle.
It was then known as the NC-27 Otsu-Gata Sensha (type B) specific to the IRJ because of its heavily modified status.
Technical Data:
The NC-27 Otsu-Gata Sensha had 6 vertical hydro pneumatic shock absorbers and ran on the three four roller bogies, also there was one independent one each side. The weight of the vehicle was approximately 8.5 tons before the additional engine conversion undertaken by the order of the IJA.
Below are some basic technical details from the French NC27 before it underwent modification by the Japanese.
BATTLE GROUND
• 7900 kg
• Crew. 3
DIMENSIONS
• Length, 4410
• Width 1700
• Height, mm 2140
• Clearance
WEAPONS
• One 37-mm gun SA18 and 8-mm machine gun Hotchkiss
• Allowance of ammunition 240 rounds or 4800 rounds (?)
• AIMING DEVICES optical machine-gun and cannon telescopic sight
• AVAILABILITY forehead housing - 30 mm
• housing board - 16 mm
• feed - 8 mm
• Tower - 22 mm
• roof - 6 mm
• bottom - 6 mm
• ENGINE Renault, carbureted, liquid-cooled, 60 hp
TRANSMISSION
• Mechanical type: 5-speed gearbox (4 +1), friction clutches and band brakes
• CHASSIS (On one side) three carts to 4 road wheels, 2 independent rink, rear wheel drive, steel caterpillar krupnozvenchataya
SPEED
• 35 km \ h on the highway
• Cruising on the highway 200 km
The suspension of the NC-27 Otsu-Gata Sensha (type B) was more or less then copied by the Japanese to be featured when they went on to produce and build their own medium tank, the type 89 which this vehicle went on to serve alongside up until around 1940. The NC-27 Otsu-Gata Sensha (type B) was mainly used as infantry support and a close quarters fighting vehicle.
