The Myrmidon is a state-of-the art warship and the Artemis Global Security's powerful flagship.
It was ordered somewhere between 2016 and 2021 and was presumably deployed into its Pacific Fleet. The Myrmidon and her frigate group was sent to the Straits of Magellan to assist its contract with Brazil and the USS James Lawrence carrier strike group. The Myrmidon took part in the Brazil operation, and after Artemis joined with Las Trinidad, the Myrmidon's captain ordered Commander Adam Bowden, the Commanding Officer of USS James Lawrence to withdraw from the Straits of Magellan at once or will be destroyed. When the Artemis pilot David Crenshaw and his wingmen found out about the attack, they defected and protected the carrier strike group from the Myrmidon's attacks. After the Myrmidon's destruction, David Crenshaw and his wingmen left Artemis and rejoined the H.A.W.X. squadron.
