Uffel Research and Development was a site situated in X2-4, a city located on the moon Uffel. This facility played a crucial role for the planet's droid community, serving as a hub for groundbreaking research and innovation in droid model creation. As the Clone Wars unfolded, the Thaereian military launched an invasion of the moon. This military threat to the droids triggered specific protocols embedded in the programming of certain Uffel droids, causing them to become hostile towards organic lifeforms. Consequently, many of these affected droids fortified themselves within the confines of Uffel Research and Development.
