The Imperial Fighter (IF) series has been instrumental to the victory the Empire had won against the Rebellion. Although they came in late, they came in hard. The IF-50's carrier capabilities and air superiority left even the Knights of the wing in awe. However, they are naturally quite expensive to produce. the Imperial Interceptor Bomber or IIB-01 Willow was designed to be a cheaper alternative to the imperial Fighter series. Featuring a more standard engine, as opposed to the unique "Shatter engine" also produced by Imperial Industries, features a unique vector thrust configuration. 2 engines up front and 2 at the back. An impressive load, and capable of landing on carriers. Typical of Imperial Industries.
