After years of trying to buy mid-air refuellers, the Indian Air Force (IAF) is now looking to convert existing Boeing 767 passenger aircraft into tankers.  Hindustan Aeronautics Limited (HAL) has entered into an MoU with Israel Aerospace Industries (IAI) to convert civil (passenger) aircraft into multi-mission tanker transport (MMTT) aircraft in India, HAL announced on 6 April.

Mid-air refuelling has been a critical capability gap for the IAF. Tankers are valuable force multipliers for air forces such as India’s, which operate fighters for long-distance missions. Mid-air refuelling almost doubles the operating range of fighters. Refuelling them mid-mission saves a trip back to base, and a landing and take-off.

IAF currently uses six Russian IIyushin-78 tankers, first inducted in 2003, but they are facing maintenance and serviceability issues.

There have been efforts under way to procure new mid-air refuellers, with both Boeing and Airbus in contention. India has been in talks with France to lease one A330 multi-role tanker transport (MRTT) from the French Air Force for training purposes under a government-to-government deal.

With leasing of defence equipment now permitted under the Defence Acquisition Procedure of 2020, the IAF could also lease, rather than buy refuellers.

Under the pact, HAL will convert civil aircraft into mid-air refuelling aircraft with cargo and transport capabilities. The contract pertains to converting the Boeing 767 passenger aircraft, which is also used by the Italian and Japanese militaries.

Boeing has a specialised tanker – KC-46 Pegasus – a variant of Boeing 767. The conversion of passenger aircraft into cargo and tankers has been a lucrative business for IAI, which has emerged as a key player in this business.

India is looking at converting at least six aircraft into tankers. The development is a setback to Airbus, which had emerged as the frontrunner in the IAF’s plans to get mid-air refuellers.

The contract between HAL and IAI, Boeing will be a key component to any future programme to convert passenger aircraft into tankers since they are the original equipment manufacturer (OEM).

In two abortive procurement attempts in the past 15 years, the IAF has floated tenders to Ilyushin and Airbus. If a tender is floated afresh, there will be a third vendor in the fray – The Boeing Company, which has developed the KC-46 Pegasus tanker aircraft for the US Air Force.

The reason for the IAF’s withdrawal of both tenders was a conflict between “procurement cost” and “life cycle cost”. Russia’s IL-78 tanker is cheaper; but the Spanish Airbus 330-200 tanker worked out cheaper in terms of life cycle costs – considering not just the acquisition cost, but also the cost of operation, maintenance and spares over a 30-year service life.
