The Age of Legends is a total conversion series based on the Star Wars Expanded Universe, from the aftermath of Endor to the defeat of the Yuuzhan Vong.
A selection of the fighters and bombers used by the Cavrilhu Pirates. Many modders to thank for this range of ships!
The Cavrilhu Pirates armed many (though not all) of their stolen bombers with Ion Pulse Missiles, which are very effective at taking down shields (but which do no hull damage). They are great for taking down the shields on Mon Calamari cruisers, leaving their Imperial employers to come in and inflict the hull damage and clean up after them.
How do you build them? Are they tied to a hero like Smugglers Alliance ships or do you build them individually?
Both! You can recruit their leader, Zothip, from wherever Moff Disra is. That unlocks Imperial Preybirds, which can be built from any planet as long as Zothip is alive, and, in addition, Cavrilhu units (IPV, Marauder, Neutron Star carrier refit) which can be built in limited numbers from wherever Zothip is. The Marauder and Neutron Star spawn mixed fighter and bomber squadrons like the ones shown.
Pirates are independent faction??
The Cavrilhu Pirates are a subfaction of the Imperial Remnant in Era 4, which, for the Empire, is the late Galactic Civil War.
