The Cerulean Sunset is a Lerontz B-26 Aircastle bomber, designed by Lerontz and flown by Aden during the Adenian-Tethish War. It is currently on display at the National Museum of Aviation, located in Juniper, Ranaj. The Cerulean Sunset is the aircraft which was used in the bombing of Geil in 511 GD.

The choice to restore and display this aircraft so soon after the end of the war was the subject of intense historical debate, with many petitions drafted by anti-war advocates across the world calling for the dismantling of the aircraft, which is lauded by the exhibit as a “technological marvel” and “proof of the air superiority of Aden”.
