An advanced development of the A-1, also known as the Falcon, with a retractable landing gear.
About this creation
The A-1C was a development of the A-1B, replacing its spatted main landing gear with a hand-cranked, retractable one. The A-1C's landing gear was notorious for both being very fragile and for taking a significant amount of time to either retract or extend, making it difficult to take off quickly.
One thing that did work about the gear's design was that, despite being outward-retracting, were mounted outward enough to give the A-1C's main gear a decently wide track.
The SBN-2 was a relatively short-lived naval derivative of the A-1C, incorporating the SBN-1's deployable arrestor hook. It was not deployed in large numbers, as most Esthen warships had rangefinders calibrated to much faster aircraft; the SBN-1, with its heavier, fixed landing gear, was slightly slower, and thus harder for the aforementioned warships to shoot down. It was later resurrected as the SBN-2B, re-engined with the more reliable R2-W, during the brief period in which Esthen attempted to bolster their navy with restored Mitsubishi A6M fighters--faster divebombers would be harder to maneuver against, as the A6M had a well-known problem with its control surfaces locking up at high speed.
The A-1C was also used more prodigiously during this time, for similar reasons. It was particularly notable in that it was the first Zephyrian aircraft with a retractable landing gear, but it was not the last time the A-1 Falcon would be used to develop a new technology...
Brief fourth wall comment: I love this shot of the A-1C divebombing.
