Antonov An-12

https://en.wikipedia.org/wiki/Antonov_An-12

The Antonov An-12 (Russian: ??????? ??-12; NATO reporting name: Cub) is a
four-engined turboprop transport aircraft designed in the Soviet Union. It is
the military version of the Antonov An-10 and has many variants.

The first prototype An-12 flew in December 1957. Over 900 had been built (both
military and civilian versions) when Soviet production finally ended in 1973.
The An-12BP entered Soviet military service in 1959. In terms of configuration,
size, and capability, the aircraft is similar to the United States-built
Lockheed C-130 Hercules. Soviet military and former-Soviet An-12s have a
defensive tail gun turret.

In the 1960s, China purchased several An-12 aircraft from the Soviet Union,
along with a license to assemble the aircraft locally. Due to the Sino-Soviet
split, the Soviet Union withdrew its technical assistance and the first flight
of a Chinese-assembled An-12 was delayed until 1974. The Xi'an Aircraft Company
and Xi'an Aircraft Design Institute worked to reverse-engineer the An-12 for
local production.

In 1981, the Chinese version of the An-12, designated Y-8, entered production.
Since then, the Y-8 has become one of China's most popular military and civilian
transport/cargo aircraft, with many variants produced and exported. A Tu-16/H-6
bomber navigator cockpit design was chosen for the Y-8 instead of the original
An-12 shorter navigator cockpit design, as the H-6 bomber had been in serial
production for some time. Although the An-12 is no longer in production either
in Russia or in Ukraine, the Y-8 is upgraded and produced in China. The latest
Y8-F600 is a joint venture between the Shaanxi Aircraft Company, Antonov
Aeronautical Scientific Technical Complex (ASTC), and Pratt & Whitney Canada.
The Y8-F600 has a redesigned fuselage, western avionics, PW150B turboprop
engines with an R-408 propeller system, and a two-crew glass cockpit. It is
unknown whether the Shaanxi Y-8 remains in production.
