M.F. Gunning

Maximiliaan Frederik "Max" Gunning (9 October 1895 – 13 February 1972) was a Dutch naval engineer who designed several warships for the Royal Netherlands Navy. He is known for designing the Dolfijn class submarines.

Early life Maximiliaan Frederik "Max" Gunning was born on 9 October 1895 in Zwolle, Netherlands, as the son of Johannes Hermanus Gunning and Cecilia van Eeghen. While this design was offered to Portugal and Norway via a firm in Paris, none were actually built. The two submarines had a mass of 755 tons while surfaced and 960 tons submerged. He became convinced that submarines with multiple pressure hulls could deliver more supplies than submarines with a single pressure hull and also the ships that managed to evade the enemy. The design of the Dolfijn class consisted of an outer hull in the general shape of a triangle, with three parallel pressure cylinders arranged inside the triangle.
