What is the required area for a single Launcher?

The required area for a single launcher is based on the specifications concerning the space needed for operational safety, efficiency, and accessibility during gunnery practices. In this case, the dimensions of 6 by 15 meters provide an adequate footprint for one launcher, ensuring that the necessary clearance is available for crew movement, equipment handling, and safety measures.

This area is designed to accommodate the launcher itself while allowing for the proper setup of any support systems and ensuring that crew members can operate safely without interference from other equipment or personnel. The other options likely exceed this requirement and may suggest unnecessary space that does not contribute to the practical operational needs of a single launcher, making the 6 by 15 meters the most suitable choice.
