A large stadium, which is to the southwest of the "main base", was completed in 1955. The bowl originally was named Sebille Stadium in honor of Major Louis J. Sebille, a Medal of Honor recipient, who was killed in action in Korea on 5 August 1950. Since the designation was never made official, the facility was later renamed. While it played host to numerous sporting and entertainment events, the Bamboo Bowl's "shining hour" came in the spring of 1975, when it and its grounds served as the site for the massive tent city that supported Operations "New Life" and "Babylift." In 1986, to honor the memory of the seven astronauts who perished aboard the Space Shuttle Challenger, the stadium was renamed "Challenger Field."
