"Operación San Lorenzo" was a military operation conducted by the Argentine Navy during the Falklands War in 1982. Its primary goal was to establish a naval blockade around the Falkland Islands to prevent supplies from reaching the British forces. The operation aimed to assert Argentine control over the disputed territory. The operation involved various naval assets, including submarines and surface ships, to monitor and intercept any incoming vessels. Despite initial successes, the blockade faced challenges due to the British Royal Navy's countermeasures and the overall strategic situation, ultimately impacting the outcome of the conflict.
