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.
Z tego powodu nie przeprowadzono żadnych dalszych udoskonaleń obrony Guam w latach 20. i 30., a bateria artylerii nadbrzeżnej została usunięta z wyspy w 1930 roku.
