I think that the only connection here, is that the brittish built one, wasn`t subject to all the stirrups and anti-gobernment campaigns that existed in Argentina (against the military coup) at the time of its construction, and as he (Hercules) was being built, he didn`t have to suffer nor go through any sabbotage as his Argentine sister did, during it. So Hercules, was built perfectly and in time, while his sister couldn`t benefit of the same instance. (The anti-government or subversive group known in Argentina as "The Montoneros", specially during 1976, had for temselves, a very big list of anti-government bombings (including among them the one that affected the ST), that had their government at the time very bussy).
Besides, afterwards came the international embargo that affected many nations in South America (for the same reasons = military coups in them), so for Argentina, each time it was harder to get any spares for her (ST) and for her brother (H), so naturally she became the source of spares for Hercules and each time as time passed by, together with what happened in 1982, she really had little hope to ever be the ship that she was meant to be.
(Good for us,
)
In her comissioned days (including those of the Falkland war), she never worked as a destroyer, for our Argentine brothers, but merely as a fast troop transport and nothing more.
