Amphibious Interstellar Assault Transport/infantry

The Amphibious Interstellar Assault Transport/infantry (AIAT/i) gunship was the predecessor of the LAAT gunships, produced over three decades before the Battle of Geonosis.

The AIAT/i was 31.5 meters long, 12.5 meters high, and had a 30-meter wingspan. It could carry either 350 cubic meters of cargo or else 50 troops, 1 repulsorlift assault vehicle, 4 speeder bikes, and 1 IM-6 medical droid. It had a number of weapons and was used by the Republic Judicial Forces as a troop transport, capable of landing on water.

The AIAT/i was a gunship with interstellar range, meant to replace the aging Meteor-class Q-Carrier. One of these vessels was used by Jaster Mereel and known by its military designation, JAST07. Later, Jango Fett used the ship and renamed it Jaster's Legacy.

Recently, Cadden Blackthorne as Mandalore managed to get his hands on several of these craft and, with some retrofitting, has made it a formidable Mandalorian war craft.
