Armada Espa�ola is the Spanish Navy (armada = navy). When we talk of the Spanish Armada, people (in the UK) generally assume that we are referring to the 1588 episode. However, the Spanish Armada goes back to 1492 and still exists under that name today.
The 1588 episode of the anglo-spanish war also gave rise to the expression, the English Armada or the Counter Armada. The armada's on both sides consisted of a 'fleet' of warships. A fleet is a collection of ships or vehicles, in this case a Naval fleet.
