The Object 770 was a prototype heavy tank designed by Pavel Isakov.
In 1956, the USSR was working on a new type of heavy tank. The Object 770 was an experimental heavy tank project developed in Chelyabinsk Tractor Plant under the leadership of Pavel Isakov. [1] [2]
The hull of the Object 770 had a sloped front like the T-54. The tank was manned by a crew of 4. The Object 770 had an NBC protection system. The turret was mounted in the front while the engine is located at the rear.
The Object 770 had a dome-shaped 3 man turret. The turret houses the 130 mm M-65 gun). The gun had a gun stabilizer and an autoloader. Day and night sighting devices were also installed in the turret. Ammunition consists of 37 rounds. A 1x 14.5mm KPVT machine gun is located in a mount behind the rear of the turret for anti-aircraft defense.
The Object 770 had six roadwheels and no support rollers. The tank had a hydropneumatic suspension for crew comfort and better accuracy. The tank was powered by a 10-cylinder, four-stroke, DST-10 experimental diesel engine. The engine also had a supercharger. The engine can output 1000 hp and allow the tank to cruise at 55 km/h. [1] [2]
In the 1960s, the Soviets embraced the main battle tank (MBT) concept and replaced heavy tanks with mobile medium tanks. All works on the Object 770 was discontinued and only a prototype of the Object 770 was built. [1] [2]
The Tiger II is a German heavy tank of the Second World War. The final official German designation was Panzerkampfwagen Tiger Ausf. B, often shortened to Tiger B. The ordnance inventory designation was Sd.Kfz. 182.. It was known as King Tiger by Allied soldiers, and is also known under the informal name Königstiger. The name Königstiger was one of many informal names used for the Tiger II.
The IS tanks were a series of heavy tanks developed as a successor to the KV-series by the Soviet Union during World War II. The IS acronym is the anglicized initialism of Joseph Stalin. The heavy tanks were designed with thick armor to counter German 88 mm guns and carried a main gun capable of defeating Panzer IV tanks. They were mainly designed as breakthrough tanks, firing a heavy high-explosive shell that was useful against entrenchments and bunkers. The IS-2 went into service in April 1944 and was used as a spearhead by the Red Army in the final stage of the Battle of Berlin. The IS-3 served on the Chinese-Soviet border, the Hungarian Revolution, the Prague Spring and on both sides of the Six-Day War. The series eventually culminated in the T-10 heavy tank.
The Kliment Voroshilov (KV) tanks are a series of Soviet heavy tanks named after the Soviet defence commissar and politician Kliment Voroshilov who operated with the Red Army during World War II. The KV tanks were known for their heavy armour protection during the early stages of the war, especially during the first year of the German invasion of the Soviet Union. In certain situations, even a single KV-1 or KV-2 supported by infantry could halt German formations. The German Wehrmacht at that time rarely deployed its tanks against KVs, as their own armament was too poor to deal with the "Russischer Koloss" – "Russian Colossus".
The T-26 tank was a Soviet light tank used during many conflicts of the Interwar period and in World War II. It was a development of the British Vickers 6-Ton tank and was one of the most successful tank designs of the 1930s until its light armour became vulnerable to newer anti-tank guns. It was produced in greater numbers than any other tank of the period, with more than 11,000 units manufactured. During the 1930s, the USSR developed 53 variants of the T-26, including flame-throwing tanks, combat engineer vehicles, remotely controlled tanks, self-propelled guns, artillery tractors, and armoured carriers. Twenty-three of these were series-produced, others were experimental models.
The T-35 was a Soviet multi-turreted heavy tank of the interwar period and early Second World War that saw limited production and service with the Red Army. Often called a land battleship, it was the only five-turreted heavy tank in the world to reach production, but proved to be slow and mechanically unreliable. Most of the T-35 tanks still operational at the time of Operation Barbarossa were lost due to mechanical failure rather than enemy action. It was designed to replace the T-28 at the time; however, very few were built.
The BT tanks were a series of Soviet light tanks produced in large numbers between 1932 and 1941. They were lightly armoured, but reasonably well-armed for their time, and had the best mobility of all contemporary tanks. The BT tanks were known by the nickname Betka from the acronym, or its diminutive Betushka. The successor of the BT tanks was the famous T-34 medium tank, introduced in 1940, which would replace all of the Soviet fast tanks, infantry tanks, and medium tanks in service.
The Panzerkampfwagen III, commonly known as the Panzer III, was a medium tank developed in the 1930s by Germany, and was used extensively in World War II. The official German ordnance designation was Sd.Kfz. 141. It was intended to fight other armoured fighting vehicles and serve alongside and support the similar Panzer IV, which was originally designed for infantry support. However, as the Germans faced the formidable T-34, more powerful anti-tank guns were needed, and since the Panzer IV had more development potential with a larger turret ring, it was redesigned to mount the long-barrelled 7.5 cm KwK 40 gun. The Panzer III effectively swapped roles with the Panzer IV, as from 1942 the last version of Panzer III mounted the 7.5 cm KwK 37 L/24 that was better suited for infantry support. Production of the Panzer III ceased in 1943. Nevertheless, the Panzer III's capable chassis provided hulls for the Sturmgeschütz III assault gun until the end of the war.
Panzerkampfwagen VIII Maus was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armored fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed, the turret being attached, before the testing grounds were captured by advancing Soviet military forces.
The Elefant was a heavy tank destroyer used by German Wehrmacht Panzerjäger during World War II. Ninety-one units were built in 1943 under the name Ferdinand, after its designer Ferdinand Porsche, using tank hulls produced for the Tiger I tank design abandoned in favour of a Henschel design.
The T-44 is a medium tank first developed and produced near the end of World War II by the Soviet Union. It was the successor to the T-34, offering an improved ride and cross-country performance, along with much greater armor. Designed to be equipped with an 85 mm main gun, by the time it was fully tested the T-34 had also moved to this weapon. Both tanks offered similar performance, so introducing the T-44 was not considered as important as increasing T-34 production. Fewer than 2,000 T-44s were built, compared to about 58,000 T-34s. Although the T-44 was available by the end of the war, it was not used in any battle. It was 1 ton lighter than the T-34-85 and slightly faster. The T-44 was heavily influential on the design of the T-54/55 main battle tank, most notably the removal of side sloping, thick frontal armor, and a low profile. Also notable was the T-44-100, a 100 mm D-10T-armed prototype, which would be the same 100 mm gun mounted on the T-54/55, bar some minor changes.
The Special Type 2 Launch Ka-Mi was the first amphibious tank of the Imperial Japanese Navy (IJN). The Type 2 Ka-Mi was based on the Imperial Japanese Army's Type 95 Ha-Go light tank with major modifications.
The IS-4, also known as the Object 701, was a Soviet heavy tank that started development in 1943 and began production in 1946. Derived from the IS-2 and part of the IS tank family, the IS-4 featured a longer hull and increased armor. With the IS-3 already in production, and when sluggish mobility and decreased need for tanks became an issue, many were sent to the Russian Far East with some eventually becoming pillboxes along the Chinese border in the 1960s. Less than 250 were produced.
The Type 5 medium tank Chi-Ri was a medium tank developed by the Imperial Japanese Army in World War II. Intended to be a heavier, more powerful version of Japan's prototype Type 4 Chi-To medium tank, in performance it was designed to surpass the US M4 Sherman medium tanks being fielded by the Allied forces. A single prototype was incomplete when the war ended.
The Uralmash-1 (Уралмаш-1) was a Soviet prototype self-propelled gun developed during World War II. It was a turretless, tracked armoured fighting vehicle designed by the Yekaterinburg-based Uralmash design bureau (UZTM) between autumn 1944 and spring 1945. It used the chassis of the T-44 medium tank and was intended to replace the SU-100 which itself had only entered service with the Red Army in late 1944. Two prototypes of the Uralmash-1 with different armament were built in early 1945, one with the 100 mm D-10 tank gun, the other with the 122 mm D-25S tank gun. While mass production was initially recommended, the end of the war with Germany in May 1945 eventually caused the project to be cancelled due to lack of necessity. If the Uralmash-1 had entered service, the 100 mm variant would have been designated SU-101 (СУ-101) while the 122 mm variant would have been designated SU-102 (СУ-102), in accordance with Soviet military nomenclature, where the "SU"-label stood for Samokhodnaya Ustanovka, or self-propelled gun.
Object 187 was a Soviet experimental main battle tank developed between the late 1980s and middle 1990s. It remains a relatively unpublicized development because of high levels of secrecy surrounding the project.
The Tiger I was a German heavy tank of World War II that operated beginning in 1942 in Africa and in the Soviet Union, usually in independent heavy tank battalions. It gave the German Army its first armoured fighting vehicle that mounted the 8.8 cm KwK 36 gun. 1,347 were built between August 1942 and August 1944. After August 1944, production of the Tiger I was phased out in favour of the Tiger II.
The experimental Type 98 Chi-Ho was a prototype Japanese medium tank. It was developed on orders from the Imperial Japanese Army. "Chi Ho" indicates that it is designated as the 5th medium (Chi) tank. A total of four prototypes were completed. Two were built in 1940 and two were built in 1941. It did not enter production.
The IS-2 is a Soviet heavy tank, the first of the IS tank series named after the Soviet leader Joseph Stalin. It was developed and saw combat during World War II, and saw service in other Soviet allied countries after the war.
The SU-100P is a Soviet experimental 100-mm self-propelled howitzer, and is designed by OKB-3 of the heavy machine construction division of Uralmash. The main designer of the SU-100P is Lev Gorlitsky. The SU-100P was intended to suppress and destroy enemy firing positions, engage armoured hostiles as well as area denial, in addition to conducting counter-battery tasks. It is intended to be the main competitor of the Object 416.
The Object 416 is a Soviet prototype self-propelled artillery. It never went beyond prototype stage. It was intended to be a low profile tank destroyer.
