Atlas Werke was a German shipbuilding company, located in Bremen.

During World War I Atlas Werke built one single U 151 U-boat for the Kaiserliche Marine, the U-156.

After the war, Atlas Werke also started to make echo sounders and other nautical instruments.

[1][2] They developed the CH3 prototype (1950), the CH4 (1958) and were sold (by Krupp) in 1967 to Varian Associates.

The company in Bremen was then sold to Finnigan in 1981 to form the Finnigan MAT brand which was acquired by Thermo Electron (becoming Thermo Fisher Scientific in 2006).
