Fuel Tank 1

Lore & Background

While larger tanks were developed for heavy lifters and deep space probes, the Fuel Tank 1 remains a staple in training missions and scientific experiments. It is often seen attached to the bottom of command pods or sandwiched between decouplers in multi-stage rockets. Its durability and predictable performance make it the trusted choice for rookie engineers who are still learning the delicate balance of thrust-to-weight ratios.

Reader's Guide

The Fuel Tank 1 is essential for constructing lightweight rockets capable of reaching low Kerbin orbit. It provides a balanced mix of LiquidFuel and Oxidizer, making it compatible with almost all standard chemical engines in the early game. When building, place this tank directly above your engine to minimize structural stress. For multi-stage vehicles, stack multiple units vertically or arrange them radially around a central core to increase delta-v without excessive drag. Strategically, use this part for initial orbital insertion and sub-orbital hops. It is too small for interplanetary travel on its own but serves as an excellent upper stage for larger rockets. Always ensure your engine's fuel consumption matches the tank's capacity to avoid running dry before achieving orbit.
