Tricycle landing gear was introduced on the Yak-18 in 1954. To provide room for the backwards-retracting nosewheel, fuselage was extended forward by 468mm. Attachment of the main undercarriage was moved from the front wing spar to the rear one, and wheels were now retracing forwards (backwards in the Yak-18).
Engine helmet cowling was modified also, providing increased frontal air intake.
Tricycle landing gear installation resulted in increase of the gross weight and corresponding degradation of the performance. In 1957 Yak-18U was replaced in production lines by Yak-18A with smaller and more powerful engine.
Yak-18U was built at Arsenyevsk (960 aircraft) and in Poland as Let C-18M.
