The ARM Construction Aircraft is a level 1 unit that is able to build level 2 towers and structures. Despite having the weakest nanolathe out of the level 1 construction units, it is considerably faster than the others, and is not affected by terrain elevation as it can just fly over the obstruction; as such, it is mainly used to repair units quickly. Each Construction Aircraft increases the player's energy and metal storage capacity by 50. Its counterpart is the CORE Construction Aircraft.
