Hesse ( / ˈ h ɛ s ə / )  or Hessia ( German : Hessen [ˈhɛsn̩] , Hessian dialect : Hesse [ˈhɛzə] ), officially the State of Hesse (German: Land Hessen ), is a federal state ( Land ) of the Federal Republic of Germany , with just over six million inhabitants. The state capital is Wiesbaden ; the largest city is Frankfurt am Main .
Though the Braunschweig class marked a significant improvement over earlier German battleships, its design fell victim to the rapid pace of technological development in the early 1900s. The British battleship HMS Dreadnought —armed with ten 30.5 cm (12 in) guns—was commissioned in December 1906,  just over a year after Hessen entered service. Dreadnought ' s revolutionary design rendered every capital ship of the German navy obsolete, including Hessen and her sister ships .
