I believe the answer is:
fleet
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">armada</span>' is the definition.<br/ ><span class="explanation-format__explanation">(fleet of ships)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for fleet that I've seen before include "group of taxis, for example" , "Group of aircraft, ships or cars" , "Squadron" , "task force" , "Quick of foot" .)
