View of the stage's RP-1 (fuel) tank.

Picture 2 of 4.

The fuel tank held approximately 203,000 gallons (1,359,000 lbs) of RP-1, a kerosene-like fuel. The tank's wall is smooth, and its bulkheads extended into the corrugated thrust structure at aft and corrugated intertank structure at forward. The tank wall incorporated a Y-ring forward and aft, allowing attachment of the thrust structure and intertank.
