sounds are the modified sound of a Vickers Vimy, a World War I bomber. Both Hasbro and Lego released LAAT models in 2002; Lego released another LAAT in 2008. Code 3 Collectibles released a die-cast gunship two years later. Within the Star Wars universe, these repulsorlift gunships were built by Rothana Heavy Engineering to serve a vital role as atmospheric transports and escorts for the Republic during the Clone Wars. The standard LAAT/i gunship (Low Altitude Assault Transport/infantry), measuring long (clearance with guns) and deep with a wingspan, can carry a platoon of 30 clone troopers with storage racks for several speeder bikes. With a maximum air speed of , the LAAT was designed specifically with low-atmosphere flight in mind, giving it an advantage engaging enemy starfighters which give up their speed advantage when fighting below mountain level. Later models however were adapted to allow short trips in deep space. The gunship's weaponry includes three antipersonnel laser cannons on swivel turrets, two forward and one rear; four composite-beam laser turrets, two mounted on the wings and two on ball turrets extending from either side; two mass driver missile launchers which can accelerate a variety of missiles at up to hypersonic velocities; and eight light air-to-air rockets carried on underwing hardpoints. The LAAT/i is crewed by a pilot, copilot/gunner, and two auxiliary turret gunners. It also carries a variety of emergency supplies, including an IM-6 Battlefield Medical Droid, collapsible repulsor stretchers, and inflatable decontamination tents. Another variant, the LAAT/c (Low Altitude Assault Transport/carrier), is crewed by a single pilot and armed with just the nose-mounted cannons, but features a pair of magnetic clamps that can quickly ferry cargo or AT-TEs into battle. Self-propelled heavy artillery (SPHA) Self-propelled heavy artillery first appear in Attack of the Clones during the Battle of Geonosis. The vehicle was initially designed on treads, but George Lucas suggested that it be equipped with legs like the AT-TEs that fight alongside it. The SPHA was referred to as "Clone Tank A" during production. Source material identifies the SPHA as one of the biggest ground guns in the Republic's arsenals during the Clone Wars, operated by a crew of 30 clone troopers. At long, the SPHA is slow but steady, reaching speeds of up to on 12 articulate legs though it must remain stationary to fire its weapon. The SPHA-T is armed with a heavy turbolaser cannon powerful enough
