Option 4 was to produce the T-64A at all Soviet factories but one and the T-72 in Poland and Czechoslovakia and at Nizhni-Tagil; in wartime three Soviet factories would produce the T-64A, and two Soviet factories and the Warsaw Pact countries would produce the T-72. The simplest was to create a thick cavity in the front of the turret that was filled with aluminum. You will enjoy reading this book while spent your free time. In 1964, the average engine lifespan was 89 hours. Steven J Zaloga, Zaloga History Books: Buy Online from - Zaloga History: All Results In Stock 262 products. The T-44 was very short-lived, as it was armed with the same 85mm gun as the previous T-34-85 tank.
At the time of the collapse of the Soviet Union in 1991, there were 3,982 T-64 tanks in service west of the Urals, with 2,091 in Ukraine. So far as is known, none of these projects proceeded beyond mock-ups or prototypes. The most radical of the rocket tanks was the Obiekt 775, a competitor to the Kharkov Astra program, undertaken by the Chelyabinsk Tractor Plant. The British engine proved to be every bit as troublesome as its Soviet counterpart. The first serial production batch of tanks was delivered in January 1969 and was subjected to factory trials. The T-72 had won strong support in the army by promising to offer a degree of reliability not found in the T-64A. The government insisted that Kharkov reach a durability goal of 150 engine hours by 1965, and 300 engine hours and 3,000 km by 1966; the ultimate goal was 500 engine hours and 5,000 km.
The Soviet numbering practice was deliberately non-standard and varied from division to division. At a range of 1,000 meters, the D-54T 100mm projectile could penetrate 235mm vertical armor plate. The Krasnoye Sormovo shipyard in Gorkiy was assigned as a war-mobilization factory for the T-64. Both the Obiekt 287 and Obiekt 775 missile tanks were canceled formally on February 16, 1968 when attention turned to the idea of using a new 125mm guided projectile from the normal D-81T gun. Antitank missiles would make heavy tanks obsolete; rockets and missiles would replace conventional artillery guns. Field trials of the Obiekt 287 started in 1965.
The army was skeptical about the use of a mechanical autoloader and wanted enough space left in the turret for a human loader. Tochmash came up with the idea of building the missile in two parts corresponding to the normal 125mm ammunition.

A small number were built for the Ukrainian Army in 2005, but widespread upgrades were constrained by the weak defense budget. It pioneered a host of sophisticated new technologies including laminate armor, stereoscopic tank rangefinders, opposed-piston engines, smooth-bore tank guns with discarding sabot ammunition, and gun-fired guided projectiles. On either side of the missile launchers were small turrets armed with a 73mm antitank rocket gun.
In January 1979, the tanks began to be fitted with the new Type 902A Tucha-1 Cloud smoke grenade launchers on the front of the turret. The senior army leaders tended to favor conservative, simple weapons since they would be operated by conscript troops with modest training. Minister of Defense Andrei Grechko came to side with the Obiekt 172 as well. It is shown in the inset drawing here. The materials that were studied included aluminum, titanium, plastics, and ceramics.
This was done during periodic rebuilding of the tanks. However, the Obiekt 775 had only a two-man crew, with the driver in the turret. Aside from the numerous requirement changes for the armament, the automotive trials of the various Obiekt 430 prototypes revealed the need The Obiekt 435 was the first attempt to mount the 115mm gun in the Obiekt 430. The controversy has continued in print in recent years, with Uralvagonzavod in Nizhni-Tagil offering their view in several of their books on tank development at the plant. The demonstration of the Obiekt 432 was so impressive that Khrushchev impulsively authorized production even though development trials had not been completed. The Chelyabinsk Tractor Plant began a similar scheme designated as Obiekt 772.

In Britain a similar belief in the power of the missile had a devastating impact on the aircraft industry. A review of the program later in the year by the Council of Ministers was harshly critical of work on the engine to date, but accepted the advances it offered and authorized additional development work. The T-64 tank was the most revolutionary design of the whole Cold War, designed to provide the firepower and armour protection of a heavy tank in a medium-weight design. However, the institute failed to overcome the challenging problems of missile guidance and the Delfin program was eventually abandoned before a prototype Obiekt 431 was constructed. He began the discussion by noting that the Obiekt 432 program, after the nuclear missile program, was the top priority of the ministry of defense.
The first batch of Obiekt 434 tanks was delivered for trials in the summer of 1966. The original configuration seen in this Soviet illustration consisted of ceramic balls cast inside the turret armor. This led to the first serial production order for the type. By August 1, 1971 the T-64 tanks will be retired to the combat training park. The tank plants in Nizhni-Tagil and Leningrad, along with their political supporters, began sniping at the Kharkov Obiekt 432, echoing the numerous complaints coming from the army.
