Was Omura Bay a fleet anchorage during World War II or mainly a weapons-testing area?
Short answerIt appears to have been used mainly for weapons testing and firing, with occasional fleet assembly.
NotesOmura Bay appears to have served primarily as a weapons-testing and firing area. It was also available as an anchorage when ships needed to assemble. These occasional concentrations supported fleet movements without making fleet assembly the bay's principal function. The distinction is between its usual work and an additional use made when suitable anchorage space was needed.
