Old spanish warship - what is it called?

It's impossible to give you a specific name without more context. "Old Spanish warship" could refer to a huge variety of ships, from different eras and with different purposes.

To help me find the right name, could you tell me:

* What era are we talking about? (16th century, 17th century, 18th century, etc.)

* What type of ship was it? (Galleon, frigate, carrack, etc.)

* Do you have any additional information about the ship? (Its size, where it sailed, any famous battles it fought, etc.)

Once I have more information, I can help you find the right name.
