Helios

Helios is a burst missile designed to be carried by Arsenal Birds. Helios missiles can be launched from very long ranges. They detonate in a blue flash of light and cause massive damage to all units caught inside the blast radius.

Origin
The origin of Helios missiles is not confirmed. The Osean AWACS Bandog was unaware of their existence until Osean headquarters provided intelligence on them, implying that Helios missiles are not Osean.

During Operation Eastern Wind, an Erusean officer laments "war merchants" not writing manuals in a language that he can understand. It is unclear if he was referring to Helios or to the MQ-99s. If he was referring to Helios, the possibility exists that Belka (the aforementioned "war merchants") developed Helios.

Deployment
Helios missiles were not used until the middle of the Lighthouse War. Before then, Osean and IUN forces repeatedly destroyed the missiles without realizing it: inside one C-17A Globemaster III during the IUN's Operation Eastern Wind, and inside two tank trucks during Operation Three of a Kind.

Helios was first officially launched in combat during Spare Squadron's Operation Flush. One or both Arsenal Birds fired Helios missiles to shoot down Spare Squadron, but they failed to destroy the squadron.

Helios missiles were not used again until the end of the war. During the Osean-Erusean coalition's Operation Daredevil, the Arsenal Bird "Justice" repeatedly fired Helios missiles to shoot down coalition aircraft. The coalition suffered casualties, but the mission continued and Trigger destroyed the Arsenal Bird.
