In early 1923, Captain
Walter Lohmann, who had acquired international business experience, gained command (
Chef der Seetransportabteilung der Reichsmarine) of the Navy's Maritime Transport Department on 28 October 1920, whose primary responsibility was logistical matters. With full confidence and trust of naval Chief Admiral
Paul Behncke, Lohmann was transferred to managing naval "black funds" generally used for covert funding. Initially, proceeds of about 100 million
Goldmark were garnered from the illegal sale of ships and submarines intended for scrapping in 1919 and 1920 under
Treaty of Versailles requirements. In addition, "Ruhr Funds" submitted by the Cabinet without Parliament knowledge were added to the fund, of which a portion, 12 million German gold marks, were intended to prepare the marines for military resistance in the
Occupation of the Ruhr crisis. Defense Minister Otto Gessler wrote in his memoirs: Ruhr fund monies were used mainly for secret weapons sales, especially in
Italy, and to build a
tanker fleet. Activities, however, went far beyond that, including: • Establishing a
marine intelligence service (), initially to ensure the supply of raw materials. • Developing a modern submarine (among other things with a bubble-free torpedo, see also
German Type II submarine) with the help of secret funds of the
Friedrich Krupp Ship Yard in
Kiel, the
AG Weser in
Bremen, the
Vulcan Shipyard () in
Hamburg and Stettin (now
Szczecin), and by the
Engineers Office for Shipbuilding () in
The Hague,
Netherlands, which was built on the basis of
Wilhelm Canaris's mediation from 1926 in
Cádiz,
Spain. • Supporting the
Heinkel,
Dornier Flugzeugwerke and
Rohrbach Metall-Flugzeugbau companies in building aeroplanes. • Purchasing the
Caspar Works, which developed "civilian" aircraft whose performance data "coincidentally" resembled those of other countries' military aircraft. • SEVERA (SEeflug-VERsuchsAnstalt), (seaplane pilot division) to develop aircraft required for Navy pilot training in
Norderney and
Kiel-Holtenau. •
Travemünde Marina A.G. to develop and maintain speedboats. • Participating in founding the Neustädter Slip-GmbH as a repair and training company for sport and speed boats. • Establishing the
German High Seasport Association HANSA to promote officers' children for secret reconstruction of the
Reichsmarine. • Making available the well-equipped yachting school in
Neustadt in Holstein to the German High Seasport Association HANSA (today DHH). ==Economic activities==
