Irken Armada

"The Irkens have a very special armada that serves for the Irken Empire Armed Forces. Just in case, there were a lot of Spittle Runners and Shuvvers that can escort the Massive, and when they're done, they'll get the Organic Sweep ready, then they could kill or enslave most of planet's inhabitants as well, then the Almighty Tallest could change a planet into a usually singular purpose."

--Su Ji-Hoon, Coming in Peace

The Irken Armada is a vast fleet of Irken vessels, seeming to consist mostly of Spittle Runners and Shuvvers, escorting the Massive, the flagship and vessel of choice for the Almighty Tallest. Whenever an Irken Invader discovers a planet's weakness, they call in the Armada to perform the Organic Sweep. When the planet's inhabitants are killed or enslaved, the Almighty Tallest give the planet a purpose (usually singular), such as an intergalactic food court or a parking structure planet.

However, in When the Cold Breeze Blows Away, the Irken Armada would intendedly assist the Coalition of the Red Star for their invasion after the Treaty of Ningbo is signed.
