As a result, no further improvements were made to Guam's defenses during the 1920s and 1930s, and the island's coastal artillery battery was removed by 1930.
Som ett resultat gjordes inga ytterligare förbättringar av Guams försvar under 1920- och 1930-talet, och öns kustartilleribatteri avlägsnades 1930.
