The runway model itself is another one of Rhino's amazing additions! 
The surrounding terrain is pretty much sorted too, again, its just awaiting a few other bits to be made to finish it off. Here's an updated minimap and a few screenshots of a Bastion (which is around 1700m x 1200m at its widest and longest points) in its current state:
An editor shot to show the full base (a large part of Bastion is in the surrounding terrain to save on space whilst still giving the impression of a larger base):
A few ingame shots:
(ignore the black patches to the right, the runway will be fixed with shaders etc in the future)
(please note that the tower in the image below is just a placeholder, as are the concrete barriers)
So what's next? Some more performance tweaks whilst I await Rhino's 'IKEA store' to finish manufacturing all its goods XD (New IKEA Store Opening in Helmand! - Project Reality Forums), then it'll be compounds, final details including all the new fields, final terrain tweaks, FOB buildings and cabling work, gamemodes, lightmaps etc, and finally on to testing
