Rising Sun is an alternate history novel written by Robert Conroy.

Two of the United States' handful of carriers in the Pacific were blundered into a Japanese submarine picket line and were sunk, while a third is destroyed the next day.

The United States Navy now only has one carrier remaining in the Pacific against nine Japanese ones, while the ragtag remnants of U.S. battleships – an armada still reeling from the defeat at Pearl Harbor in the December of the previous year – are in even worse shape.

The Panama Canal is soon clogged with traffic while towns and cities on the West Coast of America are subjected to bombing raids.

Booklist called it "thrilling", and noted that "familiarity with actual events is a bonus but not a requirement".
