How will stealth, ECM, and anti-scan devices work?
TL;DRStealth will be driven by equipment and ship traits (size, heat, power draw, hull plating) with trade-offs, while radar detects contacts and scanners get information, which items placed on cargo can slow.
Stealth – They covered it a bit on AtV. In space, infrared, electromagnetic and cross-section will make you visible. How large your ship is is a factor in that. Maybe you have hull plating that, even though you're a big ship, it disguises you. Same with heat-masking your equipment, same with power draw. Buying the specific stealth items, tailored for stealth but maybe they don't pack the biggest punch. Powerplants that are shielded but don't put out as much power, so you can't run as much. Lots of trade-off in the equipment for ships. Stealth will be driven by items. For anti-scan stuff, when you get a contact; before the scanner was 'everything', radar now detects contacts and scanner allows you to get information from it, it's why staying quiet is so important. You'll be able to place sub items so that it takes longer to scan the item. If you don't want someone to know about your cargo container, you can put items on it that will slow down the penetration of scans.
