Okay, to start with could I suggest the whole Sensors and Electronic Warfare section gets a serious rewrite in terms of what is happening with the Spacecraft Options section. It should be very clear in terms of each component just what they do and don't apply to. If there is a general name like Electronic Warfare, which applies to jamming, breaking a lock and anti-missile activities, then that is what should be used in the description of the component. Not referring to just jamming. Similarly in Enhanced Signal Processing, does this apply to rolls when somebody is trying to break your lock i.e. and Electronic Warfare roll? Really don't have a clue, I've assumed no.
Key question - if both sides have a military counter measures suite do they counter act each other when the other side tries Electronic Warfare? That is, if somebody tries to jam communications, does both the jammer and the jammee get the +6 on the dice roll if they both have the suite? I assume so. But what about Lock? What are the add ons for breaking this, I guess the bonus applies to both opponents. However I might assume that this bonus does NOT apply to both parties for anti-missile rolls. That is its the sensor operator vs the missile only and that the firing ship having a counter measure suite doesn't apply. Right? Wrong?
Does the military counter measures suite count towards avoid a lock on? No idea, I've gone with no.
I've done up a table as best I can make out on what affects aspects of combat through different tech levels from combined sensor and stealth to illustrate what may be going on. If I've got this a bit mucked up then that's significant in itself.
As the for rules balance it's a bit over the place. Not that is necessarily a terrible thing. However the for detection and lock the balance is in favor of stealth, the table below doesn't take into consideration further tech level minus for different TL systems.
As noted previously not having a tech level on the counter measures suites seems a bit strange. I've but them together as currently they are just an option between the two, no tech level progression there.
D= ability to detect an enemy
L= the ability to lock onto an enemy
EW = electronic warfare = jamming communications, breaking a lock, anti-missile
Basically up to Tech Level 13 you're struggling with detection and locks. The -2 on jamming is an uncomfortable pay off for the +2 the Improved Signal Processing offers with no tech level on the military counter measures suite.
