The Curtiss-Wright CW-19 was a civil utility aircraft designed in the United States in the mid-1930s and built in small quantities in a number of variants including the CW-23 military trainer prototype.

Design and development[edit]

Originally conceived as the Curtiss-Robertson CR-2 Coupe shortly before the Curtiss-Wright merger and the dropping of the Curtiss-Robertson brand, it was an all-metal, low-wing cantilever monoplane of conventional configuration with fixed tailwheel undercarriage and side-by-side seating for two. A prominent feature on all versions other than the original CR-2 prototypes was the large "trouser"-style wheel spats. While the design was never perfected for the civil market, it was originally intended for, a militarized version was soon developed that replaced the side-by-side cabin with tandem seating and added provision for guns and bombs.

Operational history[edit]

Curtiss-Wright hoped that in this form, it could be sold on the export market as a ground-attack machine. Orders, however, were disappointing, with only 20 purchased by the Chinese Air Force, and three by the Cuban Air Force. An unarmed trainer version was also developed and offered to the USAAC, but no orders were placed.

In a final attempt to find a market for the design, engine power was increased from 450 hp (340 kW) to 600 hp (450 kW), and retractable undercarriage was fitted. In this form, designated CW-23, the aircraft was offered once again to the USAAC, this time as an advanced trainer, but once again, the service was not interested. The CW-19 did, however, form the basis of the far more successful CW-21 and CW-22 designs.

  •  Bolivia received 10 CW-19Rs in 1938, with four remaining in service in 1949.[2]
  •  China purchased 20 CW-19Rs.[3]
  •  Cuba received five CW-19Rs in 1937, one remaining in service until 1948.[2]

Survivors[edit]

  • A single example arrived at Fantasy of Flight on March 22, 2013. Pictured is the plane packed for shipment and ready to start its journey. The plane currently sports Bolivian markings. The plane will enter the Fantasy of Flight maintenance queue and be restored to airworthy status.[4] On February 10, 2014, it flew its first test flight since restoration began.[5]
