⚠ Full profile not yet fetched. Dimensions, payload capacity, maiden flight, and manufacturer for Atlas V 521 haven't been pulled from the Launch Library 2 launcher-config API yet — this runs as a slow, paced background job so it doesn't hit the API's rate limit. The launch record below is still accurate; check back later for the rest.
