Title:  Beechcraft L-23F Queen Air

The US Army requested Beechcraft to develop an enlarged version of the Twin Bonanza and the aircraft that emerged in 1958 retained the same wings and tail but had a new longer, wider and higher cabin that could seat 10 persons instead of the previous 5. The US Army ordered 68 examples designated L-23F (later re-designated U-8F).

Beechcraft developed a civil version known as the Queen Air and built another 930 examples. It formed the basis for the later turboprop powered hugely successful King Air.
