GLSDB is GPS-guided, can defeat some electronic jamming, is usable in all weather conditions, and can be used against armored vehicles, according to SAAB's website. The GBU-39 - which would function as the GLSDB's warhead - has small, folding wings that allow it to glide more than 100km if dropped from an aircraft and hit targets as small as 3 feet (1 meter) in diameter.
根據 SAAB 的網站,GLSDB 是 GPS 製導的,可以克服一些電子幹擾,可在所有天氣條件下使用,並可用於對付裝甲車。 GBU-39——將用作 GLSDB 的彈頭——具有小型折疊機翼,如果從飛機上掉落並擊中直徑小至 3 英尺(1 米)的目標,它可以滑翔超過 100 公裏。
