How does the author use foreshadowing in The Hunt for Red October?

Early in the novel, the description of the Red October allows the reader a glimpse into the Soviet military system. The layout of the Red October focuses on the nuclear reactors and missiles. Personal quarters, especially for the regular sailors, are very cramped and not designed for comfort. This description foreshadows the comparisons to be made with the American and British made submarines and ships later in the novel.
