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 extensive redesign of the aircraft, the passenger capacity of the multipurpose airliner did not change, and only 40 people could still be accommodated on board the aircraft. Nevertheless, thanks to the use of larger fuel tanks, the maximum flight distance of the aircraft has increased significantly, reaching 1738 kilometers at its full load. Among other things, just like the Martin 2-0-2 model, the aircraft could transport various types of cargo on board, in particular, the maximum payload weight taken on board was 5200 kilograms, which made it possible 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.

The Martin 4-0-4 power plant is represented by two Pratt & Whitney R-2800-CB16 radial aircraft engines, each of which had 18 working cylinders and could develop a thrust of 1800 hp. The maximum flight speed of the aircraft also increased significantly, amounting to 502 km / h, which made it possible to overcome even long routes in a 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.
