I don’t think FACs are ideal for operating in the kinds of seas and weather found around the Falklands.
“The weather and climate of the Falklands are similar to those of the Hebrides or Shetland Islands, but with a longer and slightly more severe winter.
The Falklands are situated in the very stormy latitudes of the southern westerly winds or ‘Roaring Forties’ and gales are very frequent, particularly during the winter months.”
