The Spanish Armada consisted of approximately 130 ships, of which the largest and most powerful were the galleons. The galleons were armed with a variety of cannons, including some of the largest and most powerful naval guns of the time. However, these guns were slow to reload and had a very limited range. In addition, the galleons were slow and maneuverable, and they were vulnerable to ramming attacks.
A modern frigate, on the other hand, is armed with a variety of highly advanced weapons, including surface-to-surface missiles, torpedoes, and guns. These weapons have a much longer range and are much more accurate than the guns of the Spanish Armada. In addition, modern frigates are much faster and more maneuverable than the galleons, and they are better able to withstand damage.
As a result, a single modern frigate could easily defeat the Spanish Armada. The frigate's superior firepower, range, and maneuverability would allow it to sink or disable the galleons with minimal risk to itself.
