Aircraft program
Light single turboshaft helicopter. Marketed as Shen4T in China. Originally manufactured by Schweizer. Sold to Sikorsky in 2004. Acquired by Schweizer RSG in 2018.

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.
