Aircraft program
Light attack aircraft. Includes B-250T (trainer), Wx-250 (weather research), Wx-80 (cloud seeding), and B-350 (in development) variants.

The aircraft as engineered: what it is built from, the systems it flies with, and its configuration — each box a theme.
Technical reference compiled with AI research; a value appears only where two independent research passes and a web fact-check agree. Gaps are deliberate.
