While the Combat support airfield was cheaper than a regular airfield and could perform many of the same functions, it lacked the crucial ability to build aircraft. Therefore, a normal airfield must be built prior to the construction of support airfields.
The combat support airfield is implemented in Kane's Wrath. It was also freely buildable from the support structures tab, from both the construction yard and from cranes.
If there are Orcas and/or Firehawks in a Strike Force, a combat support airfield will be instantly constructed in the Strike Force's spawn location to accommodate them in a Real-Time battle. More combat support airfields will be constructed depending on the number of aircraft in the Strike Force.
However, as the combat support airfield drains power, this shuts down the radar, forcing the player to depower the combat support airfield if they require radar, especially if controlling a Strike Force without an MCV. The only disadvantage depowering brings is that damaged aircraft will not be repaired.
In multiplayer, building a combat support airfield will cause a desync and end the match. Intentional use of this error is considered an offence on the C&C:Online server. The unofficial 1.02+ patch fixed this issue in Releases 6 and newer.
