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, rugged, easy to manufacture 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.

Design & Development

Background

The SJ-1 was originally designated as the RY-5 Interceptor Program, an aircraft development project initiated by Ryusei with the objective is replacing the Air Force's ageing inventor of AR-3 interceptors. The project began in 1992 and at the time the RY-5 was meant as a third-generation aircraft, a cheap replacement. However in 1994 in an attempt to promote cooperation & regional security with its neighbors and partners decided to invite both Fusou and Keija into the new interceptor project. With the inclusion of international partners, the aircraft's mission & specification parameters were expanded in order to make it scalable and future-proofed. TBC
