Nope, there are 2 type of missions

First is only patrol designed area (stay close to star with binos - 100km or miles, im not sure which counts in perimeter) for 48 hours, change view and get back, star will be greyed out

Second is more confusing, its called DEPLOY AT ...... When u reach patrol area, star will grey out and u get second objective, to SINK SOME TONNAGE. I didnt found out the perimeter of patrol and how much do i need to sink for objective accomplished.
