There are so many inconguities concerning Brazil's offer of
old Tupi Type 209 submarines to Argentina.
Brazil and Argentina, over the last decade and a half, have placed submarine building and maintenance as lower budgetary and political priorities than in previous decades when each country considered the other a strategic opponent.
Put another way, two decades ago there was a mild, ongoing, Brazilian-Argentine submarine arms race.
This is no longer the case.
“The creation
of the Union of South American Nations, in 2008, was a landmark in the new foreign
policies of Brazil and Argentina. [Earlier in] another sign of mutual trust,
since 2003, diplomats from both countries occupy a single seat in the United Nations Security Council
when either of them hold a non-permanent
seat.” There is Brazilian-Argentine military
cooperation across most areas.
Hence Brazil has chosen a novel, but strangely logical, action of offering some the components of the past arms race (2 to 4 Brazilian submarines) to Argentina.
Aside from the old arms race Brazil's and Argentina's submarine forces are too weak to be seen as viable guardians of their national independence against nuclear submarine powers. Their submarine forces are simply too weak to be asymmetric responses to the overwhelming US and UK/
Falkland nuclear submarine forces that patrol the South American region. Also the US defence forces have long countered major military threats to the "
Western Hemisphere" which includes Argentina and Brazil.
Perhaps the only other serious owner of conventional submarines in South America is Chile,
with 2 modern Scorpenes and 2 older Type 209s. Argentina shares a long land/sea border with Chile
enjoying good relations.
The most valuable function of Latin American submarines may be anti-drugs and against other organised crime. But this does not make 1,000+ tonne submarines efficient or justifiable solutions.

"The Brazilian Navy has agreed to
transfer two Tupi class submarines – Type 209/1400 – to Argentina, following a
meeting between Brazilian president Jair Bolsonaro and his Argentine
counterpart, Mauricio Macro.
The deal includes a potential
future transfer of an additional two boats. The first two could be
transferred during 2019 and the ships would then receive some "minor" repairs at
Tandanor shipyard in Argentina before entering service in 2020.
The Tupi class of four vessels
was commissioned between 1989 and 1999 and is slated to be replaced by the four
Tonelero-class submarines of the Scorpene type in the near future..."
BACKGROUND
Following ARA
San Juan's accidental sinking in November 2017 Argentina's now has just one very old, semi-active submarine,
ARA Santa Cruz,
which was commissioned way back in 1984. In the following paragraphs Submarine Matters is directly citing some Portuguese-Brazilian language sources.
Meanwhile Brazil 5 Tupi class subs are reportedly non operational with S Tupi (commissioned 1989) being cannibalized for spare parts. Brazil's
S Tikuna (S-34), arguably a Tupi, was commissioned in 2006, and may not be offered to Argentina.
So far just
one of Brazil’s new class of Scorpene submarines (S Riachuelo (S 40)) has been launched and even it may not be commissioned until 2023.
Given the sporadic state of repairs the 3 available Tupi's (S Tamoio (S-31) commissioned 1995, S Timbira (S-32) 1996 and S Tapajó (S-33) 1999) have aged quickly and are in need of extensive repairs and upgrades.
Argentina’s naval shipyard
(Tandanor) chief Jorge Arosa (unlike other Argentine admirals and officials) is not enthusiastic about the Tupi deal as he
believes the Tupis are far less capable/smaller than ARA Santa Cruz. Arosa also says he has is
no idea of the true cost of repairing and refurbishing the Tupis.
