Book excerpt: This paper contains an analysis of submarine operations during the Falklands War. This was done to provide some insight on the importance of submarines in this conflict and to show the usefulness of submarines in any maritime conflict The submarine operations by both belligerents are looked at and compared over the duration of the conflict This is an unclassified study that was researched using published books, magazine articles, unpublished papers, unclassified government documents and interviews with officers involved in the conflict Reports done at a classified level were not used in the preparation of this paper. The submarine operations and methods of employment examined show the strength of submarines when properly used and the weakness when training is lacking or the submarine is used in the wrong manner. Also highlighted is the difficulty of antisubmarine efforts in a high ambient noise, shallow water environment Submarines can be a force multiplier to any navy when used properly and can frustrate an opponent by their presence or even their perceived presence. However, to get the full use of submarines they must be integrated fully into the military forces. With just a few boats in a navy, the submarines are wasted if they are operated independently. They must be fed intelligence or be intelligence platforms themselves to fully realize their potential. This point was not adhered to fully and thus submarines did not make the impact expected during the Falklands War.
