CIWS.
I'm a bit perplexed.
During the development of a new CIWS system, at fixed options for all the details, which is the reason to choose an Active Grav Sensor strength instead of another one, apart a minimal reduction of the size of the entire gun using larger sensors (12 tons fewer going from strength 10 to strength 48)?
All the statistics seems the same, included the materials to use and the development cost, regardless the sensor installed.
