What if the sensor jammer would actually be in the torpedo slot. It would have like a 1000 drain, so it couldn't be used long, and anyone who would want it to sneak up on battleships for a mass attack wouldn't be able to do so as they would have lost all their energy for shooting. Thus making it ideal for interceptor ships, or make it like the supernova, where only scout like ships could use it... it's a good idea I think but there are lot's of factors to take into account. idk
