NW055 1/144 N-1 Japan launch vehicle

The Thor missile program was initiated in December 1954, when USAF headquarters issued requirement for a tactical missile intended to travel a distance of between 1 150 and 2 300 miles. Thor was undertaken as a high-risk program having the goal of achieving flight within the shortest possible time. The Thor had its first complete launch pad test in January 1957 and a full-range flight test in September 1957.
In 1959, the newly formed NASA asked Douglas to create a civilian launch vehicle based on Thor Able. The new rocket was presenting the fourth configuration for the Thor, so it was named Delta - the military code for the fourth letter of the alphabet. The Delta M (introduced in 1968) represented siginificant leap in Delta evolution. With its Long Tank Thor first stage it hardly resembled the original Thor. The long, untapered tanks siginificantly increased propellant capacity.
NASDA developed its first N-1 launch vehicles 1 (N for Nippon) from the first stage of the Thor Delta M rocket built by Mitsubishi under license from McDonnell-Douglas. The second stage was made in Japan with an American engine and also used liquid propellants. The launch vehicle was completed by a third stage using solid propellant and 3 strap-on boosters, also based on American technology. It succesfully launched 7 satellites between 1975 and 1982.
This N-1 LV launched satellite Koku-1 on September 9th, 1975.
