T-50 개발을 이끌고 있는 이희우 준장이 앞으로 한국 공군이 EA-50, RA-50을 개발할 예정이라고 했답니다.
영국에서 무슨 학회가 있다는 얘기를 들었던것 같은데 그곳에서 발표한 자료가 아닌가 싶네요.
현재는 예산이 없지만 조만간 예산을 확보해서 2~3년 후에는 개발에 나설것이고, T-50, TA-50을 개량한 FA-50이 플랫폼이 될거라고 합니다.
EA-50에는 재밍포드와 AGM-88 함 미사일을 장착하게되고 RA-50은 electro-optical/infrared 포드를 장착하게 되는데 잠재적으로는 KF-16에 장착하기로된 이스라엘 Elop 제품을 장착할 수 있다고 합니다.
두기종 모두 FA-50과 RWR과 디스펜서를 공유하게 되고, 현재 25대의 T-50이 발주되어 12대가 공급되었고 50대는 대기중이지만 최종적으로는 FA-50을 포함하여 140대 이상으로 증가할 예정이라고 합니다.
여기에 EA-50, RA-50이 포함된 숫자인지는 확실치 않네요.

Seoul adds two T-50 variants

South Korean air force to prepare budget to start programme within three years
South Korea is to extend its development of the Korea Aerospace Industries (KAI)/Lockheed Martin T-50 Golden Eagle advanced jet trainer and light attack aircraft to add variants dedicated to electronic attack and reconnaissance duties, according to a senior official from the nation\'s air force.

Respectively dubbed the EA-50 and RA-50, the new variants are to be developed from the South Korean air force\'s future FA-50 light attack development of the T-50 advanced and TA-50 lead-in fighter trainer, says Brig Gen Hee-woo Lee, the service\'s T-50 programme manager.

Planned role equipment for the new aircraft includes active jamming pods and Raytheon AGM-88 HARM anti-radiation missiles for the EA-50 and an electro-optical/infrared pod for the RA-50, potentially the Elop long-range oblique imagery system already ordered for the air force\'s Lockheed F-16s. Additional equipment to be used in common with the FA-50 includes radar warning receivers and counter­measures dispensers, says Lee.

"The EA-50 and RA-50 are not funded yet, but we will prepare the budget this year and expect a programme to start within two or three years," Lee told IQPC\'s annual Military Flying Training conference in London last week.

South Korea has so far ordered 25 T-50s, with another 50 pending. However, Lee says the air force\'s requirement for the indigenous Golden Eagle will eventually increase to more than 140 aircraft, with its fleet to include FA-50s to replace its McDonnell Douglas F-4s and Northrop F-5E/Fs. The service plans to use combat versions to protect South Korean territory, operating beneath the more-capable F-16 and Boeing F-15K fighters to provide defensive counter-air and close-air support services.

On 1 March the South Korean air force began its first 34-week advanced training course with the T-50 at Gwang-Ju airbase, where the service\'s initial 12 examples have been delivered. The air force has completed the training of instructor pilots for the type. The T-50 - which will replace Northrop T-38, BAE Systems Hawk and F-5 trainers - also participated in a combat-readiness check in January, successfully operating alongside the F-16.
