No. No, range is 3 iirc. Helicopters on Carriers could be a problem, but their range is only 4. Destroyers, AEGIS Cruisers and other Submarines can see Submarines.Are there any unit carrying ships faster than transports (m: 6)?
Can Paratroopers start from ships or carriers and land in towns? What's their range?
Are Helicopters a threat? What's their range?
How can submarines be detected? Only by destroyers or by any ship trying to move on the same tile?
