A pirate vessel preying on ships at the edge of Federation space, whose captain, Angel, used it in 2259 to lure the Enterprise into a trap.
The Serene Squall is a pirate ship that operates beyond the Federation's border. It gives its name to an episode of the first season of Strange New Worlds, set in 2259.
A counsellor calling herself Dr Aspen asks the Enterprise to help rescue colonists taken by the pirates. Pike beams over with a boarding party and is captured, while the pirates seize the Enterprise. Aspen then reveals that she is Angel, the Squall's captain, and that the whole thing was arranged so she could trade Spock for her lover, a Vulcan prisoner held on Ankeshtan K'til.
Pike, set to work in the galley, cooks for the pirate crew and stirs them into mutiny against the first mate, Remy, then uses the Serene Squall to win his own ship back. Angel escapes.
