the thing to remember is that in the end Star Trek is a work made to entertain people, not give 100% complete picture of how the technology is used. Starfleet not using EW except when the plot says so goes dangerously close to "they're all morons" explanation and a more logical explanation is that there's a standard version of EW that's used always when "red alert" is called (possible even when "yellow alert" is called) but no attention is drawn to it as it's business as usual.EnterpriseSovereign wrote: ↑2017-07-17 09:56pmProblem is that the Feds are most often on the receiving end of electronic warfare as opposed to dishing it out. Apart from one instance on the Siege of AR-558 where Starfleet and Dominion forces would jam one another's sensors I can't recall the Feds ever using EW. The Starfleet Command games at least made use of it, with ECM, ECCM and Wild Weasel shuttles.Lord Revan wrote: ↑2017-07-17 02:18pmHonestly the built in electronic warfare suit could be enough to prevent beaming stuff in or beaming stuff out, also places like main engineering could have additional shielding not to prevent weapons fire or transporters but to protect against things like radiation leaks.EnterpriseSovereign wrote: ↑2017-07-17 12:57pm
Although as Nemesis showed, it wouldn't necessarily take much fire to get the core shields to fail! During red alert Fed ships could have some form of transport inhibitor system in place so that even if the shields fail the enemy can't simply beam stuff on or off. Seeing as the ones the Feds used were battery-powered they clearly can't be much of a power drain.
Transporter scramblers are another option, apparently they were even capable of friend/foe recognition so the ship using them can still use their own systems.
Transporters don't seem like they'd be harder to jam/confuse then the tactical sensors of the ship, so you might need a dedicated anti-transporter methods since you're normal "I don't want to get hit" or "I don't want the whole ship end irradiated if there's a minor coolant leak in engineering" methods will do the job just fine in addition to their intended uses.
This would also explain the difference between the theoretical ranges in hundreds of kilometers and actual observed combat ranges in few thousand meters. We know from the TNG episode "The Wounded" that those theoretical ranges are avaible to Starfleet vessels so the most logical explanation is that rather then everyone using only 1/100 of their potential range to "be fair" is that normally EW makes it so that those long ranges are unviable to use in combat and jamming and what not is only mentioned when it's atypical either thru presence (aka sensors are jammed when there's no logical source for the jamming) or strength.
