history

the DC-3 is an advancement of the DC1, of only one prototype builtbecame. This prototype was so much promising that it was developed further immediately to the DC-2, those more largely and stronger was than the DC1. It applied to create a competition to Douglas to Boeing B-247. Of the type Douglas DC-2 193 airplanes were manufactured.

The Douglas DC-3 was actually developed, in order to make possible for the passengers to sleep during the flight. One built couches into the DC-3 first, in order to ensure this. This system was called first DST (Douglas Sleeper transport). When one built seats into the DST again, the airplane gotits names:Douglas DC-3. The passenger capacity amounted to first 28, later up to 35 passengers.

The DC-3 had their first flight to 17. December 1935. The airplane was characterised particularly by security, robustness and high economy. In the Second World War the DC-3 cameas transporters, dragging airplane, medical airplane and passenger airline to the employment. The RAF called the airplane Dakota (British manufacture under licence); with American armed forces it had many names and designations: C-47, C-49, C-50, C-52, C-53, C-68, C-84, C-117, Skytrain, Skytrooper; with the US-Navy was called it R4D. Itan attempt execution with floats and one gave with developed engines as transport glider. The freight version had a broad, double loading door (cargo Door), in order to simplify the loading and an unloading.

the DC-3 became starting from 1938 under the designation Li-2 (Ли-2) in the Soviet Unionunder license manufactured, however with Russian М-62ИР-Motoren, which brought only 1,000 HP and with shortened wings (span 28.81 m in relation to 29,98 m). The changes settled in the maximum speed, which was clearly smaller with 322 km/h than with the DC-3; due to economical engines laybut the range of the Li-2 with 2.600 km instead of 2.160 the DC-3. Li-2 was built until 1952, finished altogether 4,937 copies.

The Li-2 gave it in all possible variations, and. A. also military (bomber, fighter-bomber, military hospital airplane) or also as UKW Übertragungsstation and as tractors forGliders. Today only a Li-2 is airworthy, which № 23441605, which is used with Flugshows. It belongs to an association in Budaörs (a small suburb of Budapest) and flies under the identification HA-LIX. Some enthusiasts built it within five years from several superseded LI-2 againup. Up to a re-tooled it still the complete original avionics and engines has government inspection department and modern radios.

After the Second World War the assigned airplanes of the American army were sold partially civilian aviation enterprises. The DC-3 did not play thereby a role which can be underestimatedin the development of civilian aviation.

Further variants under license in China and Japan one built.

Today still in the employment DC-3 present was re-tooled partly with more modern turbo-prop. (PTL) - engines, whereby its achievement and economy were somewhat improved. Outwardly one recognizes it partially by characteristics howthe extended cowls, at five-sheet propellers, or remarkably large tail pipes. There were even individual copies, with which a third engine was built in front in the nose.

even in the Viet Nam war the Dakotas became (besidetheir traditional role) heavily arms as” Gunships “assigned.

During the Viet Nam war US air Force came to the conviction the fact that a combat aircraft, which was capable of of substantial of it to fire and concentrates on comparatively small areas on the soil where itself the enemyto keep hidden could, a possibly crucial weapon represented.

The first airplane of this kind was the “Gunship I” - development of the C-47D, which originally carried the designation FC-47D and for late AC-47D “Spooky” were called. It concerned a comparatively simple modification of the which is the basis transport aircraft, thatwith three 7.62 mm MXU-470/A Minigun machine guns with multiple run and 21,000 shot ammunition was equipped. The rifles were installed on the port side of the airplane (in the fifth and sixth window as well as at the freight hatch) and could with highest rate of fire (ever 1000 shot/minute) within 3 secondsa ball in each square foot (30*30cm) of a football field shoot.

tactics in the employment consisted of flying an even link circle approximately around the goal so that the pilot the weapons could aim and fire, their ammunition throughWeapon control room was reloaded, which set off flare signals with night missions also.

Around the 32 pieces C-47D on the standard AC-47D were converted; they were starting from November 1965 with 4. Air command squadron in the employment, later in 4. and14. Air command squadron (special-in-corrode later) was divided. The AC-47D was taken in December 1968 from the service, remaining airplanes were handed over to air forces from south Viet Nam and Laos.
