Piper L-18B
The Piper L-18B was a two-seat light observation plane used by the Turkish Army during the Korean War.
After the end of World War Two Piper developed a more austere version of the Cub for the civilian market, designating it the PA-11 Cub Special. Turkey acquired 105 under a US military assistance program with the designation L-18B.
The Turkish Brigade used a few of these L-18Bs for visual reconnaissance and artillery observation during the Korean War.
