KAI T-50
The KAI T-50 Golden Eagle (골든 이글) is a South Korean supersonic trainer from Korea Aerospace Industries .
history
The development of the T-50 began in 1992 with studies by Samsung for a jet-powered supersonic trainer under the project name KTX-2. After the turbo prop trainer KTX-1 , which had its maiden flight in December 1991, this should be a further step towards the independence of the domestic aviation industry. The KTX-2 was to replace the T-38 Talon and Hawk and later the F-5 Tiger II .
Since the cost of the development was estimated to be high (it cost a total of 2 billion US dollars), a strong partner was sought, who was found in Lockheed Martin . However, this led to time delays, so that the project was only officially started in mid-1997. Financially, Lockheed Martin (13%), KAI (17%) and the South Korean state (70%) shared the costs. Lockheed Martin's influence can be seen in the design of the machine, which is similar to the F-16 .
On October 24, 1997, the contract for the construction of six prototypes (two of which only for static tests) was signed. In August 1999 the design freeze took place , in October 1999 the company KAI was founded and in February 2000 the company was renamed T-50. The first prototype was built from January 2001 onwards and presented to the public for the first time on October 31, 2001 in the presence of President Kim Dae-jung. On August 20, 2002, the prototype took off on its 39-minute maiden flight with Lieutenant Colonel Cho Gwang-Je on board. The first flight of the second prototype followed on November 8 of the same year. On February 19, 2003, at Mach 1.05, supersonic was reached for the first time. The prototype of the trainer / fighter-bomber version, known as LIFT (Lead-in-Fighter-Trainer), T-50B, A-50 or TA-50 took off on August 29, 2003, the fourth prototype on September 4, 2003 for its maiden flight.
At the end of 2003, the first firm order for 25 machines from the South Korean Air Force was placed, and on August 30, 2005, the first series machine celebrated its rollout at the KAI plant in Sachon. The official handover of the first machine to the South Korean Air Force took place on December 29, 2005 to the squadron in Gwangju . 94 machines have now been ordered, 44 of them in the TA-50 version. The first TA-50 was rolled out on January 24, 2011. A pure combat version with the designation FA-50 (including AESA radar from Elta) as a replacement for the F-5 is still to be developed. The order for this was placed in December 2008 and the first flight is scheduled for 2012. At the beginning of 2011, 20 FA-50s were firmly ordered, which were delivered between 2013 and 2014.
Using a modified version of the T-50 took Lockheed Martin on the TX program of the US Air Force in part, the aim of which was to create a modern successor to the Northrop T-38 Talon to find. The Lockheed Martin version is called the T-50A and took off on its maiden flight on June 2, 2016.
