"Fleet" can be used for both warships and peaceable merchant ships. "Convoy" requires some warships, but may involve merchant ships being protected by the warships.
The collective nouns are a fleet of warships, an armada of warships, a flotilla of warships.
A fleet of warships is usually called a fleet, and it includes many auxiliary vessels as well as warships to keep the fleet supplied and operational. Over the centuries smaller units of warships have been known by various names; task force, task group, flotilla, squadron, armada, and others.
