Yup, during the bombing raids, but the SEAD raids with XM597 there were only five Victors each way as the Vulcan had tanks in its bomb bay. The RAF certainly got a lot out of their Victors, they remained in service for another ten years and took part in Desert Storm, too.
The timing with perfect for Britain. Argentina would have had a larger number of Super Etendards and Exocets, too if the invasion had taken place later. As it was, they only had five air launched missiles.
Galtieri was feeling the pressure of public dissent. When the Junta held its coup in 1976, all dissent was brutally suppressed, but when Galtieri took over in December 1981, with the help of his pal Anaya, head of the navy and Lami Dozo, head of the air force, he enacted an expression of dissent policy and pretty much straight away crowds began gathering outside the Casa Rosada, the presidential Palace in the main square in Buenos Aires. It was a strange move, but the retaking of the islands was as much to placate the restless population that has suffered continuous hardship under the junta as it was to assert Argentinian sovreignty over the islands. Anaya and his aids had drawn up the invasion previously, and enacting it was a big part of the junta's El Processo in asserting Argentina as the big regional power.
The invasion had a short window as through intelligence Anaya had learned that a British nuclear submarine had embarked from Gibraltar and he incorrectly assessed that it was on its way down to the islands. That particular sub went north to hunt a Russian Alpha entering the North Sea, but of course two nuclear subs were already heading south for the islands, but Anaya didn't know this.
