Gross-Basenach
Gross-Basenach or Groß-Basenach is the designation for a series of five so-called M-class German military semi-rigid airships constructed by balloonist Nikolaus Basenach and Major Hans Georg Friedrich Groß (1860–1924) of the Royal Prussian Airship Battalion Nr 2 between 1907 and 1914.
They produced one experimental and four military Groß-Basenach types, rebuilding each one several times. In all they were not as successful as Major Groß wished. He was one of the sharpest critics of the Zeppelin airships, but the overall superiority and popularity of the Zeppelins doomed his own airships. Even his more successful competitors, Parseval and Schütte-Lanz, could not compete with Zeppelin after the war's end.
