The SJ-1 Okami (Myrian: 狼, Romanized: Lang / Mizuhese: 狼, lit.: "Wolf") is a fourth-generation multirole combat aircraft jointly developed by the Ryusei Rockets & Aerospace of Aldia, Tashihise-Nagadawa Heavy Industries Corporation of Keija and the Amatsuzake Concern of Fusou. It was envisioned to be a reliable, robust and inexpensive fighter aircraft. The designation "SJ" stands for Sentōki (Mizuhese: 戦闘機, and Jiānjíjī Myrian: 歼击机), both of which means fighter aircraft in their respective languages. The "1" designation indicates it is the first international development project undertaken by the three partner countries and it may not necessarily be the last as well. The SJ-1 was previously a solo development venture by the Ryusei Rockets & Aerospace and was designated the RY-5 program. It was originally meant only as an interceptor aircraft to replace the Air Force's ageing AR-3 interceptors. However in the spirit of fostering stronger ties with its neighbor & allies, the Aldian Government decided to invite its partners to develop the fighter together. The primary purpose of the SJ-1 is to serve as a multirole fighter, however there are variants that specialize in a variety of roles such as but not limited to: reconnaicense, interceptors and ground attack variants. The Commonwealth Air Force currently has 40 SJ-1Is in active service with another 180 on order, meanwhile the Commonwealth Air Territorial Forces operates a total of 180 SJ-1s of various types with a further 60 on order.
