The Oscar-B Fuel Tank is a liquid fuel tank containing liquid fuel and oxidizer.

It is the second smallest liquid fuel tank in the game, carrying 40% of the capacity of the FL-T100 Fuel Tank.

Product description

The Oscar-B Fuel Tank from Probodobodyne is a compact fuel container for small space probes, or a backup tank for other small spacecraft. Do not wash in cold water, or feed after midnight.

The Oscar-B Fuel Tank is a liquid fuel tank containing LF/O mix. This allows it to power liquid fuel rocket engines, like the 48-7S "Spark" Liquid Fuel Engine. If there are multiple liquid fuel tanks connected to an engine, then they will all be drained equally to power it. [1] The Oscar-B can be placed both in-line and radially mounted.

When full, one tank can power a single LV-1 "Ant" Liquid Fuel Engine for up to 310.3 seconds at full thrust, or a single 48-7S "Spark" Liquid Fuel Engine for up to 31.4 seconds at full thrust.

Despite its vastly smaller size, the Oscar-B has the same mass ratio and attachment properties as the FL-T, Rockomax, and Kerbodyne tanks, making it suitable in most-any case where marginally more propellant is required.


  • The "Do not wash in cold water, or feed after midnight" text in the object's description is a reference to the movie Gremlins.


  • Cost decreased from 180 to 70, dry mass increased from 0.015 to 0.025, total propellant increased from 12.735 to 40.
