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.

In Their Own Story

Engineer Joolie adjusted her visor, staring at the trembling stack on Launch Pad 1. The Fuel Tank 1 sat centrally, gleaming under the harsh Kerbin sun, its white surface unblemished by soot or stress. "Check the feed lines," she called out to the ground crew. As the countdown reached zero, a roar erupted from the Terrier engine mounted below. The tank shuddered violently as the propellant rushed upward, feeding the fire that would lift her command pod toward the stars. For a brief moment, it was just a metal cylinder; then, it became the heart of history.

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.

• This part is one of the very first components unlocked in the career mode technology tree.
• It can be stacked multiple times vertically, though aerodynamic stability becomes a concern at high altitudes without fins.
