The first overhauled Sukhoi-30 aircraft will be delivered to the Indian Air Force by the Hindustan Aeronautics Ltd (HAL), Nashik division, today.

This will be the first time ever that a used Sukhoi will be returned to the field.

Defence minister Manohar Parrikar, chief of air staff Arup Raha and HAL chairman R K Tyagi will be present on the occasion.

The handing over ceremony will take place at HAL Nashik division at Ozar at 10.30 am on Friday and the actual handover will be done between 11.45 am to 12.30 pm, TOI reported.

Managing director (MiG Complex) S Subrahmanyan of HAL Nashik division told TOI, "We are the first in the world to hand over an overhauled Su-30 to the Air Force after its full completion of 10 years and 1,500 hours of flight. Even Russia has not done it."
