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.


Before 0.23.5, it was the heaviest part, when fueled, and the largest tank. Both records go the Kerbodyne S3-14400 Tank with its release. Additionally the LFB KR-1x2 was released in 0.23.5 which can store the same amount of fuel and provide additional 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.

Product 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.
