'Regularly each year, the American public looks forward to the first showings of the new models by the country's automobile manufacturers. Not as often, perhaps, but awaited more eagerly by the Armed Forces is the appearance of a brand new combat vehicle. THE BIG PICTURE tells the inside story, from the idea to the fighting weapons, of the birth of a tank.'
Originally a public domain film from the National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

The M48 Patton is an American first generation main battle tank (MBT) introduced in February 1952, being designated as the 90mm Gun Tank: M48. Mrs. Beatrice Ayer Patton, wife of the late General George S Patton christened it as a Patton. It was designed as a replacement for the M26 Pershing, M4 Sherman variants and M46 Pattons used in the Korean War, and as the successor to the M47 Patton. Nearly 12,000 M48s were built, mainly by Chrysler and American Locomotive Company, from 1952 to 1961. The M48 underwent many design modifications and improvements during its production life. This led to a wide variety of suspension systems, cupola styles, power packs, fenders and other details among individual tanks. The early designs, up to the M48A2C, were powered by a gasoline engine. The M48A3 and A5 versions used a diesel engine, however gasoline engine versions were still in use in the US Army National Guard through 1968 and through 1975 by many West German Army units. Numerous examples of the M48 saw combat use in various Arab–Israeli conflicts and the Vietnam War. Beginning in 1959, most American M48A1s and A2s were upgraded to the M48A3 model.
The M48 Patton-series saw widespread service with the United States and NATO until it was superseded by the M60 tank as well as being widely exported. The tank's hull also developed a wide variety of prototypical, utility and support vehicles such as armored recovery vehicles and bridge layers. Some M48A5 models served into the mid-1980s with US Army National Guard units and M48A3s were used as targets for weapons and radar testing into the mid-1990s. Many M48s remain in service in other countries though most of these have been highly modified and had their firepower, mobility and protection upgraded to increase their combat effectiveness on the modern battlefield. As of 2015 Turkey is the largest operator with over 750 units in service, Taiwan is second with approximately 500 upgraded variants and Greece is third with 390 in service...
The M48 featured a gasoline-powered engine, different models were used depending on availability and manufacturer. Originally the M48(Mod A) that was built by Chrysler Defense at the OTAC Test Center (T48 Pilot #1) in 1951 used the Continental AV-1790-5B coupled to a General Motors CD-850-4A cross-drive transmission as used for the M47. The M48s built by American Locomotive used a Continental AV-1790-5C gasoline engine and either an Allison CD-850-4A or 4B cross-drive transmission. Additionally a two-cylinder, gasoline, air-cooled engine (sometimes referred to as the "Little Joe" by tank crews) was provided to power a 28 volt, 300 ampere generator when the main engine was not needed. Fuel capacity was 200 US gal (760 l) providing a cruising range of about 70 mi (110 km). The suspension consisted of six roadwheel pairs with a torsion bar suspension system and five return rollers. There was a dual compensating idler arm at the front, and dual auxiliary track tension wheels behind the last road wheels, using the T97E2 track assembly as were the previous M46 and M47 tanks. It had hydraulic shock absorbers mounted on the first, second and sixth roadwheel pairs (opposite of the M46 and M47). The bow mounted machine gun and its related crew station was eliminated thus providing more ammunition storage for the main gun. The driver's station was moved to the front center of the hull. The steering controls were redesigned. A large aircraft-styled steering wheel (replacing the wobble stick control of the M46 and M47) and placing the transmission range selector on the floor to the driver's right...
The M48's turret consisted of a redesigned flat gun shield and standard pop-up hatch for the commander's station...
