Not really. With fighters space is at a premium, they max out at 10 hull spaces(500ton).
Cloak systems are as massive at jumpdrives and don't scaledown to fighters without a very hefty research investment.
Smallcraft EW systems(both ECM and ECCM) are also handicapped. They are always no better than half the effective level of the full size ship systems.
Reduced thermal drives are useful if the OPFOR is relying on that for long range detection. But don't depend on that, active sensors consistently outrange passives for standoff detection.
Even if you have invested enough to field a beam fighter that has the TCS and thermal signature of a missile, systems at the investment level designed to engage missiles will easily kill it from beyond it's range to reply in an open space battle. The only hope is to be able to field them in quantities that exceed to OPFOR's ability to kill them before they can open fire.
I haven't fielded any fighters yet, but what about if they have good cloaking, ecm, and low-thermal drives? Is it possible to make a stealth beam fighter that can engage without getting toasted by AMM and PD?
