Ironcastle Airworks Sleanna

The **Ironcastle Airworks Sleanna** was the first foray of the SDF into ground attack aircraft, a small, low-wing monoplane with a fixed landing gear. As one of the first aircraft of Ironcastle Airworks, it did its job, but it did not do it splendidly. While capable of dive-bombing attacks, the primary purpose were horizontal attacks.

In 1938, thoughts of a single-seater fighter based on this model came up, but they were quickly dismissed.
