The Rockomax Jumbo-64 Fuel Tank (famously known as The Big Orange 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.
