The high point of her career was the Argentine invasion of the
Falkland Islands (Malvinas) in 1982, as part of
Operation Azul.
Cabo San Antonio disembarked with 20
LVTP-7 tracked
amphibious armoured personnel carriers and
LARC-V transports from the 1st Amphibious Vehicles Battalion, carrying D and E Companies of the 2nd Marine Infantry Battalion at
Yorke Bay. She did not participate further in the
Falklands War once the Argentinian landings finished.
Cabo San Antonio was decommissioned in 1997. ==References==
