But there are many other reasons — including the race to pump undersea oil and to establish
new military outposts — that have nations with Arctic coasts scrabbling, like aggressive crabs, to establish territorial rights.
To further expand your control you have to fly out to a
new, unclaimed sector and plant either the cheap radar station which will naturally pick up any ships travelling through the sector, construct a mining platform above a planet that will grant you extra resources, or go all out with a
military outpost, which costs a small fortune but will also grant control of all adjacent sectors as well.
