The TMF/A-803 LaGOWE is a mobile suit introduced in the anime Mobile Suit Gundam SEED.

In C.E. 71, ZAFT learned that the OMNI Enforcer possessed mobile suits of its own following the Battle of Heliopolis. In response, they began modifying the existing TMF/A-802 BuCUE for anti-mobile suit combat while simultaneously developing a high-performance successor unit. The result was the TMF/A-803 LaGOWE, which was developed based on the TMF/A-802 P-Mod.W BuCUE Waltfeld Custom Type.

The LaGOWE maintained the BuCUE's ability to transform between a quadrupedal mode and a cruising mode. Unlike its predecessor, however, the LaGOWE was designed with close combat and anti-mobile suit combat in mind. It was equipped with an enlarged head-mounted sensor array that allowed better intelligence gathering, a twin beam saber in its "mouth", and claws that could function as melee weapons. Its back turret weapon was also changed to a twin beam cannon. Both the twin beam saber and twin beam cannon were developed using data from the captured G Project mobile suits.

In order to compensate for the increase in weight and size, the LaGOWE was fitted with improved leg units and additional thrusters in its wings. Like the BuCUE Waltfeld Custom Type, the LaGOWE adopted a two-seater design, with a gunner seated in the front and a pilot seated in the back. With this arrangement, the gunner could make the most effective use of the mobile suit's beam weaponry, while the pilot could better concentrate on piloting, allowing the LaGOWE to be utilized at its maximum potential and demonstrate mobility that far surpassed that of BuCUE's.
