The idea is to have a way of taking all the equipment assigned to a craft and moving it to another craft present in the same base, ideally with a single click. This would save substantial amounts of player time compared to manually removing all items and re-adding them to the second craft.
This feature is aimed at players using total conversion mods because the variety of vehicles is greatly increased compared to vanilla and different vehicles are often required for certain missions. For instance in the 40k mod gear is expensive and mostly comes from crafting, you might need to move your limited equipment pool between drop pods and a thunderhawk multiple times a month until you can afford to craft two whole sets for each vehicle. XPiratez is the extreme example of this because it has many different mission types that require specific vehicles. For instance urban city missions might disallow especially wide vehicles because there is nowhere to land, aquatic missions require special submersibles, space missions require vehicles that can not only reach space but maneuver there too and so on. Some missions are stealthy infiltrations that don't allow aircraft at all and force you to use ground vehicles to maintain your cover. Hence the need to mass transfer guns and other equipment to and from specialist vehicles occurs on a regular basis.
What I'm unsure of is the best way to implement this, ideally the player could use this feature with as few clicks as possible. Maybe you could add a Transfer button to the ship equipment screen in one of the top corners, clicking on the button opens up a dropdown list of all other craft at the base, and selecting a craft moves all of the equipment from the current craft to that one.
Another possibility that fits within the current UI is adding craft to the sort list on the equipment screen. For instance if I have two skyrangers at the same base upon opening the equipment menu I could select the other skyranger as a sort category which displays only the equipment loaded onto it. If I transfer any items it removes them from the other skyranger and loads it onto the current one, just like moving stuff between bases through the transfer menu. No single click functionality this time but it would still be substantially easier.
