From 3:30 the melody is taken from Doki no sakura (同期の桜)

I would never guessed this was a 1983 song wow.
Did they take the melody from an older song?

[@JMSTranslation]

I have no information on it, but I believe it's probably an original melody.
Edit: The melodies of "艦船勤務/ Kansen kinmu" and “同期の桜/Doki no sakura" are used for its interlude.
