Den IS-7 tung tank, også kendt under sit projektnavn Objekt 260, er en sovjetisk tank, der begyndte udviklingen i 1945. Køretøjet eksisterede kun i prototypeform og blev annulleret til fordel for T-10-tanken.

Den JS-7 tank was a Soviet heavy tank that was developed in 1945 as a successor to the IS series. It was also known as Object 260 or Iosif Stalin tank. It was one of the most advanced and powerful tanks of its time, with a 130 mm gun, thick armor and a high speed. However, it never entered mass production due to its excessive weight and size.
JS-7 kampvognen blev designet af Nikolai Fedorovich Shashmurin i Leningrad. Han ønskede at skabe en banebrydende kampvogn, der kunne modstå enhver fjendtlig ild og levere et ødelæggende slag. Kampvognen havde et halvkugleformet støbt tårn, der lignede en opadvendt suppeskål, som blev et karakteristisk træk ved senere sovjetiske kampvogne. Tårnet rummede en 130 mm S-70 kanon, der kunne affyre pansergennemtrængende eller højeksplosive granater med stor nøjagtighed og gennemtrængning. Kanonen havde en autoloader, der reducerede besætningen til fire medlemmer.
JS-7 tanken havde også imponerende mobilitet i forhold til sin vægt. Den blev drevet af en 1050-hestes dieselmotor, der gav den en tophastighed på 60 km/t. Den havde torsionsstangsophæng og brede bælter, der forbedrede dens langrendspræstationer. Tanken vejede 68 tons, hvilket gjorde den til det tungeste medlem af IS-familien og en af de tungeste kampvogne, der nogensinde er bygget.
The JS-7 tank had formidable armor protection that could resist most enemy weapons. The front hull had a pike nose design with 150 mm of sloped armor at 65 degrees, which increased its effective thickness against frontal attacks. The lower hull had 100-120 mm of armor at 30 degrees. The sides had 150 mm of upper armor and 100 mm of lower armor, with inflatable fuel bags behind them for extra protection. The turret had 350 mm of armor on the mantlet and 240-250 mm on the sides and rear.
The JS-7 tank was tested in late 1945 and early 1946, but it faced several problems due to its massive size and weight. It was difficult to transport by rail or road, and it could not cross many bridges or tunnels. It also consumed a lot of fuel and required frequent maintenance. Moreover, it was deemed too expensive and complex to produce in large numbers, especially after the end of World War II when the Soviet Union faced economic difficulties.
Therefore, the JS-7 tank project was cancelled in favor of the T-10 tank , which was lighter and simpler than the JS-7 but still retained some of its features such as the hemispherical turret and pike nose hull. Only six prototypes of the JS-7 were built, one of which is preserved at the Kubinka Tank Museum near Moscow.
