The deal, reportedly valued at over $2 billion, is under discussion between the Argentine government and French defense contractor Naval Group.

The advancement in talks coincides with Argentine Defense Minister Luis Petri's official visit to Paris, during which key discussions were held to finalize the potential agreement. According to various sources, the two nations are close to signing a Letter of Intent that would outline the terms for the acquisition of the submarines, including the provision of associated services such as spare parts and training.

This move comes at a critical time for Argentina's Navy, which has been without operational submarines since the tragic loss of the ARA San Juan in 2017. The lack of operational subs has severely diminished the Navy’s capacity for maritime control, surveillance, and reconnaissance. Currently, the Argentine fleet consists of two non-operational submarines, the ARA Santa Cruz and ARA Salta, the latter of which is primarily used for training purposes at the Mar del Plata Naval Base.

While the signing of a Letter of Intent does not legally bind either party, it sets a positive precedent for Naval Group, whose Scorpene-class submarine has already seen adoption in other regional navies. Chile currently operates two Scorpene submarines, and Brazil is in the process of incorporating its third unit, part of a planned four-boat fleet under the Riachuelo-class designation.

Technical data

These submarines have a length of approximately 66.4 meters and a beam of 6.2 meters. Their submerged displacement is around 2,000 tons. Powered by diesel-electric propulsion, the Scorpène-class submarines feature four diesel generators that charge the batteries used for underwater operation. These submarines are capable of reaching speeds up to 20 knots when submerged, with a maximum surface speed of 12 knots.

The operational diving depth is reported to be around 300 meters. Each Scorpène-class submarine typically has a crew of about 31 to 35 sailors, including officers. The submarines are equipped with six 533 mm torpedo tubes capable of launching torpedoes, anti-ship missiles, and laying mines. Their weapon systems include torpedoes such as the Black Shark or the Exocet anti-ship missile, depending on customer preferences.

The endurance of these submarines can extend up to 50 days, and their range is estimated to be around 6,500 nautical miles at 8 knots while surfaced. Advanced versions of the Scorpène class can incorporate air-independent propulsion (AIP) systems, which enhance underwater endurance by reducing the need for surfacing to charge batteries.
