Please let me preview the weapons in the shipyard before ordering. Now I have to order a ship, pay the price and change to the system reserve, to see the weapons.
You can just not from the shipyard! Buying from the shipyard is a shortcut, the original way was from the fleet menu, just as you do it in the very beginning. My suggestion do not use the shipyard if you want to see the loadout properly but create a new fleet and use the + button which opens the vessel options, there you can see it. I am sorry but it is just not feasible to do it in the shipyard.
