The Kerbodyne S3-14400 Tank is the largest tank containing 72 t of liquid fuel/oxidizer mixture. Compared to the Rockomax Jumbo-64 Fuel Tank which contains 32 t it holds 2.25x the mass of fuel. It is also slightly taller. In addition, it holds the impressive title of "heaviest stock part in the entire game."


The S3-14400 is by far the largest tank, best used for supplying the similarly wide KR-2L+ or KS-25x4. A single tank is approximately the maximum amount of propellant a Mainsail can usefully lift.

Product description

When nobody believed in (or even asked for) an even larger fuel tank than the already enormous S3-7200, Kerbodyne stepped up with the sanity-defying S3-14400 model. Carrying fully twice as much fuel as before, this fuel tank may just pack enough propellant to justify its proportionately enormous cost.


Kerbodyne's signature super heavy fuel tank. Designed to be used with their advanced rocket engines.
