In 1931, the navy once more made headlines in Chilean politics when large portions of it (26 ships) began a mutiny that demanded the president to rescind a salary reduction. The demands were later expanded to include an agrarian reform, industrial "solidarity", and the payment of the external debt by the "millionaires". The mutineers had their ships located at Coquimbo and Talcahuano's naval base, which they controlled. Chilean government responded by sending the Chilean Air Force to bombard the ships in Coquimbo and charging Talcahuano's naval base. After the quelling of the rebellion, the navy was purged, though the mutiny had its origin among the lower ranks.
