History: The C-47 was the most important military transport of WW2,
and yet today, five decades later, it remains in service with the air
arms of more than 25 countries around the world.
The C-47 traces back to the DC-3 airliner, an improved development
of the earlier DC-2 which made its first flight in 1934. The DC-3
flew for the first time on December 17 1935 and went on to become
the mainstay of US domestic airlines in the years prior to World War 2.
The entry of the US into WW2 in December 1941 would have a
profound effect on the fortunes of the already successful DC-3 (more
than 400 had been built by then). The US Army Air Force's requirements
for transport aircraft were well met by the in-production DC-3,
with the result that as the C-47 Skytrain it became the standard
USAAF transport during the war. More than 10,000 were built for service
with US and foreign air arms; in British service it was named Dakota.
Postwar surplus C-47s became the standard equipment of almost
all the world's airlines, while many US surplus C-47s were also sold
or donated to the world's air forces. In the USSR it was built in
quantity as the Lisunov Li-2.
The C-47's longevity has resulted in a number of turboprop conversion
programs to improve its performance. Two notable convenions
are the Basler Turbo-67 and Professional Aviation Jet Prop DC-3, both
of which feature a small fuselage stretch and two Pratt & Whitney
Canada PT6A turboprops. A small number of operators have converted
their C-47s to Turbo-67 standard, while South Africa is converting
30 or so to Jet Prop standard.

ถ้าจะว่าไปแล้ว การนำสายการผลิตของเครื่องบินพาณิชย์มาเป็นต้นแบบของเครื่องบินทหาร หลังจากสงครามโลกครั้งที่ 2 ก็ยังมี Boeing 707 ครับ ในส่วนของกิจการทหารจะใช้ชื่อว่า C-135, ส่วน Boeing 747 ถูกพัฒนาต่อเป็นเครื่องบิน Air Force One ในชื่อ VC25, เครื่องบินตรวจการ หรือ AWAACS ในชื่อ E4B ด้วยครับ _________________ รักรถไฟมั่นใจโคปเตอร์ || Railway Racing Team || Korat Spotter
