The Dragon of the Sea

'''Herbert, Frank. The Dragon in the Sea' (vt. 21st Century Sub)''. 1955. New York: Avon, 1955, 1956.

In submarine warfare in the near future, the tunnel from which submarines exit their base is "a birth canal. Going through it is like being born. This sub is a perambulating womb looking for a place to spew us out." The sub is "afloat in amniotic fluid" (181), and the captain becomes "almost literally a part of his boat" (184 and passim).
