I am in agreement with the volume and price increasing by the number of back-ups installed.

 

Light bulb turns, okay in my case a stick caught fire, the active sensors are using a bunch of small antenna spaced along the hull to

create the illusion of a single large antenna.

 

Increasing the power requirement when adding a back-up system keeps calculations simple and will save time in having to go back and fix

my spreadsheet.

 

Okay active sensors with back-ups double everything, except crew and USD.

I’ll agree that at TL-10 the AEMS is the system that has the back-up since it has the best short range of 480,000 km which is 180,000 km longer

than a LADAR/LIDAR.

 

Unfortunately, I apparently forgot to mention that my question was for the TL-9 Medium Military Sensor package that has RADAR and LADAR/LIDAR active sensors. The Active sensor USD of 4 appears to be for a LADAR/LIDAR system with a short range of 120,000 km. The radar’s best short range is

60,000 km which would result in an active USD of 2.

 

I was not able to recreate the TL-9 Medium Military sensor package in the QSDS 1.5e table by having two RADAR and 1 LADAR/LIDAR or

1 RADAR/2 LADAR/LIDAR systems using either a fixed or folding array, which prompted my question.

 

My guess is the LADAR/LIDAR has the back-up since the HRT has the range to pick-up a target.

 

Thank you for the help, back to work.
