PG-5
this was the designation of a series of gunnery droids which were prototyped by Industrial Automaton during the New Order. They were originally designed to augment the crews of Imperial warships with mechanical weapons, shield, and sensor operators. The PG-5 series was based on the P2 astromech design from IA, making it a large, bulky machine which was programmed to operate, repair, and maintain the ship's systems. However, these droids had to communicate via scomp link, limiting their usefulness in combat. Also, their programming was not voerly aggressive, so their ability to shoot down a target in battle was minimal at best. After the Empire rejected the prototypes it ordered from IA, the PG-5 series was discontinued.
