A blast wall served as a security measure implemented at spaceports, designed to protect vessels from being stolen and to ensure the safety of the facility. The Graith starport, situated on Goroth Prime, had a blast wall encircling it. At the spaceport located on Zelos II, blast walls were in place; however, they proved ineffective in preventing a Special Ops team from absconding with the YT-1300 light freighter, known as The Maker.
