Operation Opal (Codename 0PA1) was an operation initiated by the Australian Government in the 1970s to create a new fighter aircraft for the Royal Australian Air Force. The Australian Government wanted a design that was cheap to produce and easy to fly. The RAAF made a deal with Northrop Grumman to create the aircraft. The first prototype was built in 1974 and cost a total of 1 million dollars (in today’s money) per unit. A second prototype was introduced in 1979 and after testing, entered service with the RAAF in 1981. However, the aircraft was pulled from service in 1989 after 4 tragic crashes. One in 1982, one in 1983, and two in 1985. This aircraft was replaced by the much more reliable F-18 Hornets in the 90s. Lore aside, this vehicle is actually very hard to control. I only reccomend trying to fly this if you are a professional pilot. I may add weapons in the future. AG8 controls the gyroscope btw. This is my first plane, I hope you enjoy.
