In February 2000 the KTX-2 programme was renamed as the T-50 Golden Eagle, while a light-attack variant of the basic design was designated A-50 (later redesignated as the TA-50).
The next two T-50 prototypes, which were configured as TA-50 aircraft (see below) completed the four T-50 aircraft stipulated under the FSD contract (see above).
The 22 examples of the TA-50 ordered alongside the second batch of T-50s in November 2006 represented the LIFT version of the Golden Eagle.
The first production TA-50 was rolled out at Sacheon airbase in January 2011, with deliveries to the 115th Squadron of the 16th Fighter Wing at Yecheon airbase in the central RoK taking place between March 2011 and 2013.
The HHP, meanwhile, selected the TA-50 to meet its requirement for a light-attack and LIFT aircraft in August 2012.
In November 2006 the RoKAF placed another order for 47 TA-50s for delivery from 2008.
The 50th and final T-50 (not including the TA-50s that were part of the second RoKAF order) was delivered in May 2010.
