What is the maximum capacity of one tank module in the SIXCON system?

In the context of the SIXCON system used for tactical fuel operations, understanding the specifications of its components is crucial. The maximum capacity of one tank module in the SIXCON system is indeed 900 gallons. This specification is important for operational planning, logistical assessments, and ensuring that fuel distribution meets mission requirements without exceeding the tank's capacity.

Knowing that one tank module can hold 900 gallons helps in calculating how many modules would be necessary for larger operations or contingencies. It also plays a critical role in safety considerations, preventing overfilling and ensuring that the system operates effectively within its designed parameters.

This information is key for personnel involved in fuel management and tactical operations, ensuring efficiency and compliance with operational standards. The other capacities provided in the options do not accurately represent the SIXCON tank modules' specifications, further solidifying that 900 gallons is indeed the correct maximum capacity.
