Star Trek: Every* Starbase Ranked Worst To Best

Sol Station appears in the third season of Star Trek: Picard, replacing the long-lived Spacedock One. This upgraded station bore a strong resemblance to its predecessor, though featured additional structures and platforms. It was also far larger, evidenced by the ships it could accommodate. 

When the Frontier Day celebrations began in full earnest, the Enterprise-F exited Sol Station via the doors on its mushroom-shaped head. These were similar in design to those made famous by the theft of the Enterprise some hundred years earlier, though the Odyssey-class ship dwarfed her earlier namesake.

Sol Station was equipped with a vast array of weapons and defenses, allowing it to hold off the entire fleet for a short period. This allowed several key Federation representatives to escape the Borg Armada in orbit, though even this mighty station fell to the combined strength of the captured ships. It would suffer catastrophic, though not total, damage. It was saved by the timely intervention of the Enterprise-D.

It would take almost a full year for the station to return to its former glory, though it was ready to host the launch of the newly rechristened Enterprise-G.
