In March 1947 aboard the ARA “Patagonia” commanded by Lieutenant Commander Leandro M.B. Maloberti, a slightly more suitable aircraft is transferred, since it has its cabin closed in the fuselage, it is the Walrus M-O-2, whose crew is composed by: Frigate Lieutenant Oscar Tachella, Corporal 1º Mechanic R. J. Román and Mr. Pedro Pouchulu photographer. One of the tasks assigned was to intensify the aerial reconnaissance activity and to start using aerial photogrammetry in the hydrographic surveys, a task that will decide the incorporation of airplanes and equipment capable of carrying out this type of surveys for the next decade.
In December of that year the Sea Fleet was deployed, with the Cruisers “Brown” and “25 de Mayo” with Walrus aircrafts, to continue the exploration tasks.
