Airbases are not produced directly by cities. They can be constructed by Engineers, Seabees or Infantry units can change into Airbases.
Once an Infantry has changed itself to an Airbase, it cannot change itself back again.
Airbases cannot move or attack, but are otherwise identical to Infantry in combat.
They have the added advantage of being able to see 2 squares instead of one on the ground.
Their primary use is as a place to land and refuel air units.
In this, they are similar in performance to Carriers, but can hold any type of air unit, not just Fighters. Airbases can hold an unlimited number of units at any one given time.
They also can hold other ground level units, but be aware that they offer those units no protection from attack. An Airbase can take four hits to kill. If destroyed, all air and ground level units at the Airbase are destroyed with it.
Unit Statistics: 4 hitpoints, melee attack strength of 1.
A good strategy is to get Airbase established as you expand. It will help get you to explore areas you couldn't early on in a game. This could get you ten or more turns ahead of your opponent if not doing the same. Also hunting and eliminating other players Airbases will stunt their expansionist goals.
Another needed strategy is to pair an Airbase with Coastal Guns. Coastal Guns have limited sighting and require other units to spot for them. Use Reconnaissance aircraft set to patrol areas where you would like the Coastal Gun to cover.
If the Airbase is close to front lines put appropriate units in place to help shield it from threats.

The Oil Facility is used to exploit resources to aid in combating the resource drain. It has the capability to act as a road on land terrain and shallow waters.
Unit Statistics: 3 hitpoints, melee attack strength of 1.

--------------
The Fort is designed to serve as a defensive position for gathering land units.
Forts can be constructed by engineer and Seabee units on most land-based terrain. Forts have a capacity of 6 portage points.
When an enemy unit tries to attack a fort that has units inside it, the attacking unit must first defeat all the hosted units by Siege Attacks. The attacked unit is randomly picked at the time of combat, and it enjoys the defensive capability of the fort.
If a Fort is attacked and it is empty, it may be destroyed.
Unit Statistics: 8 hitpoints, melee attack strength of 1.
The Fort has no combat or ranged fire capability. The Fort is best deployed near Airbases and Coastal Guns to provide security by filling it with units determined to be the best deterrence for aircraft or land units seeking to invade.

The Coastal Gun is designed to serve as a static Battleship, making city capture difficult from a sea approach.
Coastal Guns can be constructed by Engineer and Seabee units on most land-based terrain. Coastal Guns can only be built on: Clear, Forest, Snow, Desert, Hills and Mountain terrain.
The Coastal Gun can only carry a General.
Unit Statistics: 18 hitpoints, melee attack strength of 3, it has an effective fire of 8 spaces and does 3 damage. They cannot move.
The Coastal Gun takes 48 turns to be constructed by an Engineer or Seabee. Daisy chain them together to add a further defensive beltway your opponent will need to breach. Back them up with Airbases, Forts and mines to help keep their longevity from Aircraft and Land units. The Coastal Gun cannot be repaired so be sure to protect them well.
The Coastal Gun cannot be built in a city.

--------------
The Port is a unit that can hold ships and most ground level units. It has only the minimum of defenses.
Ports are constructed by Engineers and Sea Bees on land based terrain. Ports can be built together in such a way to produce man-made waterways across continents.
Ports can repair damaged ships at a rate of one point per turn, if the unit in question has not moved.
The Port is capable of storing Infantry like units, serving as a waypoint for transport.
Ports have an unlimited stacking capability. If a Port is attacked and destroyed, all the units inside it are likewise destroyed.
Unit Statistics: 10 hitpoints, melee attack strength of 1.
