At its core, the plane Martin 4-0-4 is nothing more than an upgraded version of the model Martin 2-0-2, however, the similarities are there is only a purely external, as the aircraft design has undergone a number of changes, in particular, it was largely strengthened fuselage of the aircraft, its main processing performed flight performance etc.
Nevertheless, despite the fact that the model by Martin 4-0-4 was largely better than the previous version of the aircraft, the great popularity of the airliner was also unable to find among business customers, and in 1953, the aircraft was officially removed with the release. In two years, the production of American engineers were able to build 103 aircraft, at the same time, to date, remained one suitable for the operation of a copy of which is stored in the Museum of Air Glory (USA).

Despite the large recycling of aircraft design, multipurpose passenger airliner has not changed, and on board the aircraft for the only 40 people could still accommodate. However, through the use of larger volume of fuel tanks, the maximum distance of the aircraft following the largely increased, reaching at its full load 1738 kilometers. Among other things, as well as the model of Martin 2-0-2 plane could carry on its board and various kinds of goods, in particular, the maximum net weight of cargo received on board was 5200 kg, which allows you to actively use the aircraft for these purposes.
Plane by Martin 4-0-4 also found its application in the Air Force, in particular, the liner was used in the US as a transport aircraft, and the aircraft is capable of carrying on its board until 50 soldiers.
Powerplant Martin 4-0-4 represented by two radial aircraft engines Pratt & Whitney R-2800-CB16, each of which possessed 18 working cylinders and could develop traction in 1800 hp Maximum airspeed of an aircraft also greatly increased, making 502 km \ h., Which allowed even to overcome the length of the route of the minimum time.
Due to the processing of aircraft design by Martin 4-0-4, greatly improved its reliability, only 4 air incident that occurred in part because of the actions of the crew were officially registered in particular in the history of the operation of these aircraft, and partly because of technical problems.
