Helipad (Tiberian Sun)

GDI and Nod helipads were support structures designed to build, refuel and rearm aircraft. Without them, aircraft would be left without ammunition to perform any offensive role. These iterations were used during the Second Tiberium War and the Firestorm Crisis.

Background
As the technology became more sophisticated, helipads evolved. In the Second Tiberium War, the weapons were much more complex and required longer reload times than their predecessors due to their integration within the frame of the aircraft at a greater level than previous generation gunships. Nod redesigned the original circular platforms, relocating the fuel tanks and weapon racks to the outside to allow swift rearming and refueling of Harpy assault helicopters and Banshee fighters, while GDI developed what essentially was a bunker with a helicopter landing pad on its top, which was compatible with most ORCA aircraft, including the Orca Fighter, Bomber, and Carryall craft. An unique quirk is that all type of helipad can reload ammunition onto any strike aircraft in position, regardless of the faction technology trees and aircraft assigned to them.

Legacy
Helipads were decommissioned following the Firestorm Crisis in favor of GDI airfields and Nod air towers, which can house multiple aircraft at a time as well as construct attack helicopters.

In-game
Each helipad can only serve one aircraft. If the structure is captured, the parking aircraft is captured as well. If every helipad is occupied, newly built aircraft will appear from a random point on the edge of the map and fly directly to the helipad which is set as "primary".
