Who Argentine carrier ASW doctrine was meant to fight

Argentina adopted broadly useful American anti-submarine methods with the Soviet threat in mind, but its assumptions about British submarine behaviour proved dangerously incomplete in 1982.

Question

Who was Argentina's US-derived carrier ASW doctrine intended to counter?

Short answer

Primarily Soviet submarines, but it was meant to work against any threat and was weakened by poor assumptions about British behaviour.

Notes

ASW doctrine is not confined to one opponent because the same search problem applies to any hostile submarine. Soviet submarines were the principal model, while Brazil, Chile, and Britain remained possible regional or political threats. During the Falklands War, Argentine expectations were shaped by an incomplete understanding of NATO doctrine and underestimated Royal Navy submariners' aggressiveness. Imported doctrine can fail when local planners misunderstand how a specific opponent applies it.
