"Miguel de Cervantes" performed her trials at sea in December 1929, reaching a speed of 25 knots, three more than the Navy requirement. Along with her sister ship "Almirante Cervera", she took part in the repression of the 1934 Asturias Revolution, shelling the neighborhood of Cimadevilla and, along with the battleship "Jaime I", transporting troops and munitions to Gijón.
