The Kerbodyne S3-14400 Tank is a extra large (3.75m) liquid fuel tank. It contains 72 t of liquid fuel/oxidizer mixture, which is 125% more compared to the Rockomax Jumbo-64 Fuel Tank (which contains 32 t).

It is the largest tank available in the base game, containing twice as much fuel as the Kerbodyne S3-7200 Tank. In addition, it holds the impressive title of "heaviest stock part in the entire game."

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.



The S3-14400 is by far the largest tank, best used for supplying the similarly wide Kerbodyne KR-2L+ "Rhino" Liquid Fuel Engine or S3 KS-25x4 "Mammoth" Liquid Fuel Engine. A single tank is approximately the maximum amount of propellant a RE-M3 "Mainsail" Liquid Engine can usefully lift.

When full, one tank can power a Kerbodyne KR-2L+ "Rhino" Liquid Fuel Engine for 120.0 seconds, or a S3 KS-25x4 "Mammoth" Liquid Fuel Engine for 55.6 seconds, while at full thrust.

The S3-3600, S3-7200, and S3-14400 all have the same radius, mass ratio, and cost ratio. This means that the S3-14400 is interchangeable with two stacked S3-7200 tanks or four stacked S3-3600 tanks. However, as a single part, the S3-14400 is more structurally stable than a stack of the smaller tanks.


  • The product description describes the Kerbodyne S3-7200 Tank as Kerbodyne's signature fuel tank. Prior to version 1.0, the Kerbodyne S3-14400 Tank was described as Kerbodyne's "signature" tank, and this description was used instead:
Kerbodyne's signature super heavy fuel tank. Designed to be used with their advanced rocket engines.
