The SAB-333 Slibnas (English: Dragon) II is a single-seat, twin-turbofan, swept-wing, subsonic attack aircraft developed by SAB for the Siluan Air Force. In service since 1995. In service since 1995, it is named for the SAB-133 Slibnas, a Eracuran War-era fighter-bomber effective at attacking ground targets, but is commonly referred to as Karalienė (English: Queen). The SAB-333 was designed to provide close air support (CAS) to friendly ground troops by attacking armored vehicles, tanks, and other enemy ground forces; it is the only production-built aircraft designed solely for CAS to have served in the Siluan Air Force. Its secondary mission is to direct other aircraft in attacks on ground targets, as role called forward air controller-airborne; aircraft used primarily in this role are designated OO-333.

Development

In the early 1980s, the need for an attack aircraft dedicated to the CAS (close air support) role was identified by the Siluan government. While the Ku-7 Kraujasiurbis attack aircraft that had been in service since 1956 was tough, agile, and well loved by its crews it was deemed insufficient for the CAS role in the quickly evolving combat environment of the 1980s. Requirements put forth by the Siluan Airforce called for an aircraft that was simple and quick to both produce and maintain, have a relatively short take-off run, be highly durable, have an integral cannon, and also have a weapons load of at least 6,000 kg. A design competition for the new aircraft began in 1982 and by 1984 Siluan companies Kubulius Design Bureau and Siluano Aviacijos Darbai (SAB) as well as the Tennaiite Nikita Corporation. Kubulius submitted their Ku-ES11 design, SAB submitted thier ES331, and Nikita submitted their already in production AF-11 Pangolin.

Initially, the Siluan government and the Siluan Air Force considered the Nikita offering as it was already in production and would thus save on development cost and the need to establish new production lines as well. By 1986 though, there was a new Pukias Sualkaranė, Skaidre Jarockis, and Air Force Command. Jarockis and and the new Air Force Command insisted upon a domestically designed and built aircraft and subsequently dropped the Nikita AF-11 from consideration.
