After Argentina signed the Rio Pact in 1947, three Grumman Geese, 0184/PGM-1, (C/N B.53, BuNo 37800), 0185/PGM-2, (C/N B.29, BuNo 37776) and 0186/PGM-3, (C/N 1100, BuNo 3846), were suplied by the U.S.A. to this country to be operated by the Navy. The first couple (0184/PGM-1 & 0185/PGM-2) were of the JRF-5 model, while the third (0186/PGM-3) started life as a JRF-1 model in 1939 but in 1940 it was part of a batch of ten JRF-1 aircraft converted to the JRF-4 model, which allowed them to launch depth charges. This first batch of three aircraft would in the years to come serve with the Armada Nacional de Paraguay (ANP). Then in 1947 three more Geese of the G-21A model, 0293/PGM-4, 0294/PGM-5 and 0295/PGM-6, would be acquired.
From 1946 to 1957 all of the Geese would initially use serials of the Prefectura Naval Argentina (PNA) but in fact they were operated at discretion by the Navy which was in control of the Prefectura at that time. This was done to hide this purchase from the government of that period which was politically against the Naval Aviation. This forced the Prefectura to buy some four Nord 1203 Norécrin to perform some of the functions required.
Since all of these aircraft were equipped with radios they were ideally suited for fishery control, patrol, surveillance, SAR, MEDEVAC, light logistics and general utility duties, but in practice they saw limited flying. Last but not least, they did operate in the Antarctic in four summer campaigns. It seems that, even thought they could be armed with one rack under each wing for either a 250 lbs bomb or a 325 lbs depth charge, they were never used by the Argentinean Navy, nor by the Prefectura, with any kind of weaponry. They were based at B.A. Jorge Newbery and operated by the Escuadrilla Aeronaval de Patrulleros. By 1957 another couple of Geese, PNM-7 and PNM-8, of unknown model would be acquired. For a brief period, just before being finally transferred to the operational use of the Prefectura sometime in 1957, they were reserialled as follows, 3-P-21 to 3-P-25 and 3-P-50 to 3-P-52.
The service of these Geese was very similar with the Prefectura with the exception of the Antarctic missions performed by the Navy. When finally operational control was transferred to the Prefectura they were reserialled as PM-1 to PM-8. They finally were retired in from service in 1963 and some of them, PM-1, PM-2, PM-3 and probably PM-5, would be transferred in 1967 to the Armada Nacional de Paraguay. The fate of the reminders is unknown.
