Bombers Vs. Fighters

Fighter drop, always a good option. When I was growing up I always told my mom I wanted to be a fighter drop pilot they were so awesome!
Why replace fighters with bombers?

Space.

Bombers and Fighters both take up 1 hangar spot. Bombers do twice the damage making them ideal for long distance operations. They also do more damage to cruisers and carriers making them more efficient when you are fighter dropping a fleet with those in it.
Bombers of course are not good meat unless you are using Heavy cruisers or higher but can really increase the amount of firepower you have on long distance operations! As well as rip cruiser fleets apart with ease. (There will be no survivors hehe!)

Technology.
Yes, that is the one major barrier. However, if you decide to use bombers as your new drop unit, laser tech isn't as important as you will be using them nearly 100% for their armor value to reduce losses so you can focus research on missiles to improve bomber attack.
