Fyron says:

Once you have encountered a ship design in combat once, you can always see it's design later. So, scanner jammers on non-cargo ships are only useful for brand-new, top secret designs. Once you use the ships, the enemy will always be able to know their designs. After the enemy has seen your ships in combat, the only thing that the scanner jammer can do is prevent them from seeing if your ships are damaged or not and what cargo (if any) they carry.

Fascinating! I was going to post the results of my discussion with you guys but that is going to have to wait until digest this and reformat my presentation.
