Krall's Attack on Yorktown

In 2263, during the third year of its five-year mission, the Kelvin-timeline Enterprise stopped at Yorktown, a vast new Federation starbase. A stranger's plea for help drew the ship into an uncharted nebula, where a swarm of small vessels commanded by the warlord Krall tore it apart. The surviving crew were captured or scattered across the planet Altamid.

Krall wanted the Abronath, an ancient bioweapon component the Enterprise carried. With help from Jaylah, a scavenger who had made her home in the wreck of the long-lost USS Franklin, Kirk's officers regrouped, freed their crewmates and relaunched the old ship. They learned that Krall was in fact Balthazar Edison, the Franklin's former captain, who had been abandoned a century earlier and had come to despise the Federation.

Krall's swarm struck Yorktown, but the Franklin's crew disrupted it by broadcasting loud music over its communication network. Kirk pursued Krall into the starbase and expelled him and his weapon into space before it could be released. Starfleet then began building a new Enterprise, the NCC-1701-A, for the crew to continue their mission.
