Final answer:
The author of “Under Pressure,” also known as “The Dragon in the Sea,” detailing a submarine's harrowing mission, is Frank Herbert, famous for his “Dune” series.
Step-by-step explanation:
The novel “Under Pressure,” detailing the perilous journey of a submarine crew, was written by Frank Herbert, who is also known for his famous science fiction series Dune. Although Arthur C. Clarke, Isaac Asimov, and Ray Bradbury are notable authors within the science fiction genre, it is Frank Herbert who authored “Under Pressure”, also known as “The Dragon in the Sea”, before his breakthrough novel “Dune” was published. This novel predates his work on the complex ecological and political saga of the desert planet Arrakis found in the “Dune” series.
