The ship was sent out to the Kuiper Belt shortly before the First Formic War to test the Glaser, a revolutionary new mining tool. The Makarhu was used to bump the free miner ship El Cavador from the asteroid they were mining in order to test the Glaser on the rock. The Makarhu assisted in the attempted sabotage of the Formic scout ship, but it escaped the destruction of its gamma plasma exhaust when it fled the scene of the battle.
