Four members of the class saw action during the 1982 Falklands War, three Batch Two conversions, HMS "Argonaut", HMS "Minerva" and HMS "Penelope" "Argonaut" experienced 15 air attacks in San Carlos Sound and was hit by a number of bombs and cannon fire; it was stranded for six days, with two bombs lodged in the forward Seacat magazine and boiler room. The first Seawolf conversion HMS "Andromeda", was one of only three Seawolf fitted frigates available with the Royal Navy's newest missile in the war and served during the war as the critical "goalkeeper"- the last line of defence for the carrier HMS "Invincible" during the war. The five unconverted, gun-armed, broad-beam "Leanders", arrived in the war zone in the last week of the conflict and immediately after it to serve with the post-war task force led by the brand new carrier HMS "Illustrious". An Argentine naval dive team made a serious attempt to place limpet mines on HMS "Ariadne" at Gibraltar during the conflict. The last "Leander" commissioned in 1973, like the two built for Chile, carried special electronic warfare systems, for countering Exocet missiles, and the Argentine services may have anticipated the "Ariadne" was scheduled for service in the Total Exclusion Zone, which in fact did not happen until after the end of the war.
