You're not strictly enforced to do it, you can place masses of Interceptor weapons on bombers, what I meant is that heavier anti-attack craft weaponry and anti-ship weaponry gets increasingly larger, and the I/S/B is mainly just a means of defining the max level of weaponry you can place on the craft. Interceptors can be built/launched in swarms, are very fast but cannot wield heavy anti-AC weaponry, they're mainly limited to swarming enemy S/Bs and mainly harassing them, superiority fighters can carry swarms of Interceptor weapons but they can also carry some heavier, longer-ranged anti-AC weapons, but they are slower - designed to fulfill a more defensive role, escorting warships and bombers and protecting them from enemy interceptor/superiority attack. Bombers are simply the minimum size ACs that can carry anti-ship weapons, but you can also cram Heavy Bombers with Interceptor weapons and thereby spread out your to-hit chances against ACs. Normal PD can only target seekers, and modded PD will be a threat to ACs but if you put enough armor on them they'll be able to hold their own against ships with PD. Bombers will thus be a pretty serious threat for smaller warships, and can be an effective support when attacking capital warships, but since PD will be less effective against them, you'll need interceptors and superiority fighters to take out enemy bombers before they can cause serious damage/interference to your fleet.
