Wilhelmshaven is in East Frisia. The city's current population is about 75,000.
The most controversial piece of infrastructure, however, is an entirely civilian one; the JadeWeserPort, Germany's largest harbor project. It was opened in 2012 and is intended to become the third largest German port on the North Sea (after Hamburg and Bremen), however transport volumes have stayed well below expectations as of 2015, leading to charges that the project is a "white elephant".
By carA29 is intended to serve as a major transportation route to and from the harbor and thus also serves as a good entry point to the city.
Wilhelmshaven railway stationRegional trains run from Oldenburg (every half-hour to hourly), Osnabrück (every half-hour to hourly) and - several times daily - Bremen. If you arrive from further away you will probably have to change trains at one of the latter two.
By planeThe next major airport is in Bremen (BRE), but depending on your plans it might also make sense to fly into Hamburg (HAM), as there are more flights to Hamburg than to Bremen.
By boatThe harbor mainly caters to freight ships, and does not have many ferry connections. Wilhelmshaven is not a stop on many cruise-lines. A connection to Heligoland was ended in 2014 due to lack of demand.
By busWilhelmshaven has a city bus system, but it does not accept the Niedersachsen-Ticket.
