The Oscar-B Fuel Tank provides fuel to attached liquid fuel engines.

It is currently the second smallest liquid fuel tank in the game, containing enough fuel to run the tiny LV-1 at full throttle for 307.7 seconds. It carries 74% of the capacity of the next largest fuel tank (the R-4 'Dumpling' External Tank) and 20% of the capacity of the FL-T200 Fuel Tank.

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.
