100 gun ship-of-the-line Rayo of this Spain navy was launched in the royal shipyard located in Havana in 1749.
Although built at the beginning in the name of 80 gun ship of the line and "San Pedro", it was behind renamed by the "Rayo".The reason is not known.
As a result, it became 100 gun warships of a 36-pound gun x 32 and 18-pound gun x 32 and 8-pound gun x 32 and 18-pound carronade gun x6.
By this modification, firing-guns-broadside capability increases the staff from 890 pounds to 1010 pounds, and a boarding staff increases the staff from 670 persons to 830 persons.
Those days, the ship equipped with the gun which crosses 80 gates on a two-layer deck was not built even in the British navy till 1813.
Incidentally the firing-guns-broadside capability of a HMS Victory 1148 pounds (at the time of the battle of Trafalgar),
It was 904 pounds for the 98 gun ship-of-the-line HMS prince of the British warship equipped with the equivalent gun of a Rayo and an equivalent class.
Moreover, it may also be able to be called modification of foresight when it considers that they were 1030 (or 1048) pounds, if it is a 98 gun ship-of-the-line HMS Dreadnought.
It may be able to be said that the firing-guns-broadside capability in the Santisima Trinidad of 136 gate warships was change for the worse as it was said well that it considers that 112 gate warship Santana of this Spain warship was 1508 pounds by 1530 pounds (at the time of the battle of Trafalgar).
Since the Rayo which finished modification construction in 1803 has not participated in the strategy in West Indies before the naval battle of Trafalgar, either, it has not participated in the naval battle (battle of Cape Finisterre) in the Cape Finisterre offing on July 22, 1805, either.
(France x16 ships + Spain x6 ships vs British x15 ships).
Furthermore, also when it sorties from Cadiz towards the naval battle of Trafalgar, it becomes a ship of the last which was not blessed with a good wind but from which it departed.
Since the combined fleet changed its course 180 degrees when the naval battle started, a Rayo is seen at a naval battle, as located in the head group, but since the ship leg was late, it is located in a battleline's outside.
Although her squadron divided when Nelson divided the battleline of the combined fleet and devised the attack moved forward, became in the end of a battle, and once rushed into the battle area again and Britannia etc. and a gun game were held, the posture was never, and since it did not run away, it was captured after all.
Although the Rayo only took out the damage of four persons killed in war and 14 injured persons with the naval battle of Trafalgar, by the postwar storm, fire was released to it by the captured British Navy, and it was abandoned.
