# Manteniendo libres los mares [Ensuring Freedom of the Seas] [Spanish]

A photograph shows the 16-inch guns of a battleship firing, with sailors in the foreground, in a blue star-bordered frame beside an American flag and a portrait of President Roosevelt. The Spanish text says the ship is unequalled in armour and striking power and that the US Navy, with 343 warships and 345 building, can meet any attempt by aggressor nations to close the world's sea lanes. The flag, stars and portrait attach national symbols to the navy (transfer).

MANTENIENDO
LIBRES LOS MARES

La fotografía muestra los cañones de dieciséis pulgadas del acorazado norteamericano "North Carolina", recientemente puesto en servicio, en los momentos en que disparaban proyectiles de una tonelada a 42 kilómetros de distancia. Este buque de guerra, cuyo costo de construcción ascendió a 715 millones de pesetas, es uno de los cinco recientemente botados al agua, y no hay ninguno que le iguale en el mundo en materia de blindaje y potencial de ataque. La Marina de Guerra norteamericana, con 343 buques de guerra en servicio y 345 más en proceso de construcción, está en condiciones de hacer frente a cualquier intento de cerrar las rutas marítimas del mundo que puedan tener los paises agresores.

EL PRESIDENTE ROOSEVELT

KEEPING THE SEAS FREE

The photograph shows the sixteen-inch guns of the American battleship "North Carolina", recently placed in service, at the moment they were firing one-ton shells to a distance of 42 kilometres. This warship, whose construction cost amounted to 715 million pesetas, is one of the five recently launched, and there is none in the world that equals it in armour and offensive power. The American Navy, with 343 warships in service and 345 more under construction, is in a position to face any attempt by the aggressor countries to close the world's sea routes.

PRESIDENT ROOSEVELT
