Development
Curtiss-Wright anticipated the requirement for this type of "high-performance" aircraft and designed the Curtiss-Wright CW-25, a twin-engine trainer, which possessed the takeoff and landing characteristics of a light bomber aircraft.
Using the same basic design as the larger [Vous devez être inscrit et connecté pour voir ce lien], the new CW-25 was designed to be simulate the demands of multi-engine operations.

The design featured a small layout, grouping two Lycoming R-680-9 radial engines forward and using a retractable tail-wheel landing gear to achieve the performance necessary to meet the requirements of an advanced trainer.
The single CW-25 prototype acquired for evaluation had a welded steel-tube fuselage structure with the wings, fuselage and tail unit fabric-covered.[Vous devez être inscrit et connecté pour voir ce lien]

Operational history
The first prototype Model 25 flew in 1941 and the production version entered service as the AT-9 in 1942.
Named the "Fledgling" by Curtiss-Wright, it commonly became known as the "Jeep" in the [Vous devez être inscrit et connecté pour voir ce lien] (USAAF).[Vous devez être inscrit et connecté pour voir ce lien][Vous devez être inscrit et connecté pour voir ce lien]

The AT-9 was purposely designed to be less stable and proved be difficult to fly or land, which made it particularly suitable for teaching new pilots to cope with the demanding flight characteristics of a new generation of high-performance, multi-engine aircraft such as the [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien].

A total of 491 AT-9s were built before production ended and a new production run of 300 of the generally similar AT-9A commenced.

Because of its difficult flying characteristics the AT-9 was not offered for sale to civilians after the war, although many non-flying examples were given to ground schools for training purposes.

Survivors
Two AT-9s survive today with one AT-9A on permanent display at the [Vous devez être inscrit et connecté pour voir ce lien] in [Vous devez être inscrit et connecté pour voir ce lien].
This aircraft required extensive restoration, and was the product of the museum staff incorporating two incomplete airframes together, along with parts fabricated on site.
While the wreckage of an AT-9A recovered from a crash site in 2003 was turned over to the [Vous devez être inscrit et connecté pour voir ce lien] for restoration, the aircraft is incomplete and will require a long and extensive restoration for display.
