Bomber is space vessel role describing combat craft designed to deliver massive amounts of destruction to large or area targets. Their primary methods of delivery are ordnance called torpedoes and the namesake bombs. Bombers use these ordnance to attack other vessels and ground targets respectively.
Sizes
Bombers come in multiple different sizes.
Small
Small bombers are ideal for carrier operations against a variety of targets. Though the curtailed size of their ordnance limits their effectiveness against the truly gargantuan super-capitals, the number of ships fielded together can flexibly scale to tackle many target sizes.
Medium
While less flexible than small bombers, medium bomber craft can carry more or a wider variety of ordnance and operate with greater independence.
Large
Large bombers are capable of carrying the largest torpedoes and bombs, allowing them to deliver battle- or even war-winning amounts of damage.
Operations
Whether ground- or carrier-based, bombers are a naval commander's primary asset in fighting against hard targets. They, however, do not always have the ability to withstand fighter attacks unaided.
Space
While capital ships may dominate volumes of space and space lanes, bombers are fielded to attack them and their support vessels. Whether stealthy insertion of an Eclipse or a massive formation of Retaliators, their torpedoes cause havoc and destruction within enemy fleets.
Ground
Dirt side targets include massed infantry, bunkers, armor columns, and airfields. A bomber may be used to soften up IADS for easier insertion of ground forces or to interdict ground transport supply lines.
