Tucan T-18B NB-2
Designed as a one-off prototype, this was the prototype T-18 fitted with a Spartan inline engine and new nose section ahead of the cockpit. The fuselage was strengthened, a section inserted aft to maintain the cg, new undercarriage fitted, altered fuel system and some aerodynamic refinements added. It first flew on July 6 1938 and then went for trials with the Aviacion Naval. Since then it has been brought by both Chile and Brazil as a land-based attack aircraft and the FAA has ordered a batch of 40 as the NB-2 to replace the older NB-1 between 1940-41.
