You are probably looking for the "StoredShips" event, I see it in my logs a few seconds before I swap ships ("ShipyardSwap") so I think it is entering the shipyard screen that emits it. However it is just a short description of each ship not full outfitting. To get full outfitting, you need to actually swap into each ship as then you will get the "Loadout" event for the new ship each time. There isn't (currently) an event that gives full outfitting for all owned ships.
