Project 571 (Solar timeline)

Project 571, also referred to as the Red Watch mutiny, was an insurrection within the Red Watch led by Lin Lizhang against commander Xu Qifeng and vice commander Liu Tongguan. The mutineer group, calling themselves the New Sol faction, attempted to assassinate Xu who was on an airship headed for Hohai city, while attempting to frame Liu for the crime. The mutiny, which was secretly backed by the Pirate Confederation, ultimately collapsed and all mutineers were killed.

Hohai battle
Xu rode with Lin on an airship bound for Hohai with about 30 of Lizhang's men as escort. It was on this airship that Lin planned to assassinate Xu and pin the blame on Liu.

Liu Tonggua showed his true colors by thwarting Lizhang's attempt on the commander's life and fought his way to the back of the airship, bringing the commander with him.

Shi, deciding to turn on Lin and his mutineers, attacked the airship using 2 hijacked police helicopters. Rocket-propelled grenades fired from the helicopter by Shi hit the tail fins and engines, forcing it to crash land. Lin fell out of the airship in a brawl with Xu and Liu, in which the latter was mortally wounded shielding Xu. As the airship made a crash landing, Shi's mercenaries landed to finish off survivors. A still alive Xu shot at Shi, hitting him in the leg. 2 mercenaries were killed in a shootout, before Shi withdrew his forces as local police approached. Xu and Liu were sent to the city hospital where Liu was pronounced dead, while fire helicopters began dousing the burning airship.

Mutiny in other areas
Following the attempted assassination of Xu at Hohai, attempts were made to arrest Red Watch officers suspected to be linked to the coup, resulting in violence in [capital] that lasted several days. All of the mutineers were killed in a series of shootouts and standoffs.

Aftermath
While the Red Watch commander Xu Qifeng survived the ordeal, Shi's forces had accomplished their primary objective of diverting government attention away from investigating officials affiliated with the Confederation. The Red Watch's investigation of government corruption was halted, as the government wished for an investigation of the Watch itself for its failure to prevent malicious actors such as Lin from entering Watch ranks.
