The Rockomax Jumbo-64 Fuel Tank provides fuel to attached liquid fuel engines, and was the largest liquid fuel tank prior to 0.23.5. The appearance of the tank, including the rust-like orange colour is inspired by Space Shuttle external tank. However, unlike the real life counterpart containing liquid hydrogen and liquid oxygen, the Jumbo-64 contains the unspecified liquid fuel and oxidizer.


That's how many fuel tanks can SAFELY go on the same craft.

As of 0.23[outdated], this tank does not transfer heat effectively. Engines attached directly to it and running at full throttle (especially Mainsails or LV-Ns) risk overheat. Throttling down, or placing a fuel tank (such as the Rockomax X200-8 Fuel Tank) or structural component in between the engines and the Jumbo-64 fuel tank will fix this. Another workaround for this problem is to stack two Rockomax X200-32 Fuel Tanks in place of a Jumbo-64. Together they have exactly the same mass, fuel capacity, drag and dimensions but different part count which might impact on the performance of the game.

The Mainsail produces less heat in 0.22. Its heat production was lowered from 500 to 400, reducing the chance of overheating. The LV-N will no longer overheat under this tank as of 0.22. The Aerospike has a higher maximum temperature as of 0.22, also reducing its overheat risk.

There is a "01" label near the top lip of the fuel tank.


Before 0.23.5 it was the heaviest part, when fuelled, and the largest tank. Both records go the Kerbodyne S3-14400 Tank with it's release. Additionally the LFB KR-1x2 was released in 0.23.5 which can store the same amount of fuel and additionally provides engines. So even between all tanks with a large radius, or smaller, the Jumbo-64 tank is not the heaviest part and shares the record of the largest tank of that radius with the LFB KR-1x2. Of the tanks introduced in 0.23.5 it's only larger than Kerbodyne S3-3600 Tank which is the smallest of the new tanks.

Manufacturer's description

The largest tank available from Rockomax, the Jumbo-64 holds a vast amount of fuel in a friendly orange insulated container. Contrary to popular belief, the Jumbo-64 is NOT orange flavored and should NOT be tasted.
