It is interesting to remember that during World War II, the whaling ships Indus 3 and Indus 4, were transferred to the Navy, taking the names of P3 and P4 (patrollers), and with an officer's naval crew and 17 seafarers. , keeping on board the Captains who represented the company. In these units, the harpoon gun was exchanged for a 47 mm cannon.

They operated during 1942 and 1943, in patrol activities, from Iquique to Valparaíso passing through Juan Fernández, and in defense exercises of the ports of Iquique, Tocopilla, Antofagasta and Chañaral. In the 60's the fishing company "Ruiz" acquired the Indus 7 and 9, those that were named Ruiz I and Ruiz II, vessels that were dedicated to shrimp fishing.
