Whaam!

The left-hand panel shows a fighter plane firing a rocket that, in the right-hand panel, hits a second plane which explodes in flames. Lichtenstein adapted the image from several comic-book panels, with the primary source being a panel illustrated by Irv Novick from a 1962 war comic book. Lichtenstein transformed the source by presenting it as a diptych while altering the relationship of the graphical and narrative elements. Whaam! is regarded for the temporal, spatial and psychological integration of its two panels. The painting's title is integral to the action and impact of the painting, and displayed in large onomatopoeia in the right panel.

Lichtenstein studied as an artist before and after serving in the United States Army during World War II. He practiced anti-aircraft drills during basic training, and he was sent for pilot training but the program was canceled before it started. Among the topics he tackled after the war were romance and war. He depicted aerial combat in several works. Whaam! is part of a series on war that he worked on between 1962 and 1964, and along with As I Opened Fire (1964) is one of his two large war-themed paintings.
