The IAF’s Elusive Quest for a New Tactical Transporter

25 Apr , 2014

Antonov AN32

Although it is certainly important to have an indigenous aerospace production base, a monopoly (as HAL has enjoyed so far) is not conducive to efficiency. Some private sector competition might help HAL to shape up, as state-owned Air India is doing after the entry of private airlines. However, if no foreign entity is willing to enter the Indian defence market by tying up with Indian industry, the Avro replacement process needs to go ahead in any case by purchasing a suitable tactical transport aircraft off the shelf. The IAF’s requirement is urgent and cannot be delayed much longer lest safety issues begin to emerge with the ageing Avro fleet.

The Avros are by far the worst off, as they are fast approaching the half-century service mark…

The Indian Air Force (IAF) is in the throes of an exciting transformation into a strategic air force. Armed with the latest aerospace technology it will gradually be able to extend its vigilance, reach and power. Although fighter aircraft rightly dominate the process, transport aircraft are no less important, and the IAF is striving to greatly boost its airlift capability by the end of the Twelfth Plan (2017). Once again, though strategic airlifters regularly make the headlines, tactical transport aircraft are equally necessary. One of the important requirements of air power is that it should offer a range of options – tactical as well as strategic. This applies also to the transport fleet, where a balanced structure is imperative. The question therefore arises – is the IAF transport fleet balanced?

Delayed Action

The recent enhancements of the IAF’s airlift capability have come after a gap of almost 30 years. It was in the mid-1980s that the transport fleet witnessed a flurry of activity as the government at last recognised that the IAF needed to be better equipped to meet its numerous responsibilities. First, the Dakota and Packet fleets were replaced by 110 Antonov An-32 twin-turboprop medium-tactical transport aircraft, from 1984 onwards. Then, 17 four-engine Ilyushin IL-76MD jets were acquired in place of the An-12 turboprops, commencing 1985. The giant 43-tonne payload IL-76 was the IAF’s first true strategic airlifter and made a dramatic difference to its transport fleet. Finally, in 1988, Dornier Do-228 light transport aircraft were inducted to replace the Otter and Devon aircraft for communication, liaison and training duties. All these aircraft are still flying today, as is a large fleet of HS 748M Avro medium transport aircraft.

Avro HS748

The twin-turboprop Avros with a payload capacity of 5.1 tonnes were acquired from Britain’s Hawker Siddeley from 1964 onwards and later produced under licence by HAL. About 56 remain in service, employed primarily for communication and medium lift tasks. The IAF’s current predicament stems mainly from the urgent need to replace the ageing Avro fleet.

Fleet replacement is a hugely expensive process. Since most of the current transport aircraft were inducted over a short period, practically the entire fleet is falling due for replacement, at a cost the nation can ill afford. The IAF’s transformation plan therefore has three key components – “preserve and maintain”, “upgrade and improve” and “replace and acquire”.

Overall, the strategic end of the airlift spectrum looks reasonably healthy.

Today, less than half the IL-76 jets can be operationally employed but they will be preserved and kept in service for some more years, perhaps with the help of an upgrade. The An-32s are already undergoing a mid-life upgrade in Ukraine, under a $400-million contract signed in 2009. The programme that will run till March 2017 includes overhaul and re-equipment of 40 aircraft in Ukraine at the rate of ten aircraft annually. The refurbishment of the airframe as well as improved avionics will help increase the service life of the fleet to 40 years i.e. at least till 2025.

The cockpit layout is being modernised, noise and vibration reduced and crew comfort, reliability and maintainability enhanced. The payload capacity is also being increased from 6.7 tonnes to 7.5 tonnes. The balance 64 aircraft will be upgraded at the IAF’s No 1 Base Repair Depot at Kanpur. The Dorniers are in reasonably good shape and these too can be preserved to meet the IAF’s requirements till around 2025. The Avros are by far the worst off, as they are fast approaching the half-century service mark. And being of vintage technology, they need to be replaced by modern tactical transport aircraft as soon as possible.

Strategic Surge

In recent years the IAF’s strategic airlift capability has seen a significant surge. The process began in 2008 with a $1.2 billion contract for six Lockheed Martin C-130J Super Hercules four-engine turboprop aircraft. These planes are already in operational service and have proved their worth in natural calamities. The C-130J with a maximum payload capacity of 19 tonnes, or 92 fully equipped troops, is today the world’s most widely used military transport aircraft. The IAF’s C-130Js are customised for Special Operations, for which the service lacked a dedicated platform thus far. They can undertake deployment of Special Forces in all-weather conditions, even in complete darkness. They can also be employed for tasks such as airborne assault, air transported operations, air supply, air maintenance and disaster relief. Another six aircraft have been cleared for induction and these are expected to be based at Panagarh, West Bengal. The total of twelve aircraft should be adequate to meet the IAF’s Special Operations requirements and augment its heavy lift capability if required.

The truly exciting enhancement of strategic airlift was the $4.1 billion deal concluded in 2011 for the purchase of ten Boeing C-17 Globemaster III four-engine jets. The first few of these iconic aircraft have already been formally inducted into the newly-formed 81 Skylord Squadron, based at Air Force Station Hindon, and all ten are due in by the end of 2014. With a payload capacity of 74.8 tonnes, well above the 43-tonne load of the IL-76, and a range of 2,400 nautical miles without refuelling, the C-17 aircraft is a true game-changer for the IAF. Another six C-17s may also be inducted, although the window of opportunity to do so is closing since Boeing has already announced plans to shut down its long-running production line in 2015. If the Indian government does take a timely decision to enhance the strength of the IAF’s fleet to 16, half the number is expected to be based at Panagarh. These 16 C-17 planes should be adequate to meet the IAF’s strategic airlift needs for some years, particularly since they will be backed up by the remaining IL-76 aircraft.

In September 2010, Hindustan Aeronautics Limited (HAL) also signed a joint venture agreement with United Aircraft Corporation (UAC) of Russia to co-develop a twin-jet Multi-role Transport Aircraft (MTA) as replacement for the An-32. The aircraft is intended to have a cruise speed of 430 knots, a range of up to 1,460 nautical miles and a payload capacity of about 18.5 tonnes. The high wing, rear loading MTA will have features such as fly-by-wire, full authority digital engine control, modern avionics and a glass cockpit. Although the MTA is classified as a tactical transport aircraft it may also be employed in some strategic roles. It is expected to fly for the first time in 2017 and enter production both in Russia and India in 2019. The IAF plans to order 45 aircraft initially and a follow-up order is possible.

Tactical Troubles

Overall, the strategic end of the airlift spectrum looks reasonably healthy. If the government clears the IAF’s demand for another six C-17s, the strategic fleet will consist of 16 C-17s and perhaps eight to ten IL-76s. A dozen C-130s, meant primarily for Special Operations can also shoulder some strategic tasks if required. At least 45 MTA, perhaps another 45, have about ten years in hand to replace the 104 upgraded An-32s. These MTA too lie close to the strategic end of the scale. But once the An-32s are retired from service the low-end tasks need to be carried out by purely tactical transport aircraft – medium-lift planes of about five to ten tonne payload capacity that will ultimately replace the HS 748 Avro.

So what is the IAF doing about it? A global tender valued at about $2.5 billion for the supply of 56 aircraft to replace the Avro fleet was floated in May 2013. The Request for Proposal (RFP) was sent to eight foreign manufacturers – Casa/EADS, now renamed Airbus Military (Spain), Alenia Aermacchi (Italy), Boeing and Lockheed Martin (United States), Antonov (Ukraine), Ilyushin (Russia) and Embraer (Brazil). The RFP specifies a twin-engine cargo aircraft with six to eight tonne payload capacity, a cruise speed of 800km/h and a range of 2,500 to 2,800 km. It envisages buying these aircraft from a foreign Original Equipment Manufacturer (OEM) who must tie up with one or more Indian private sector players and nominate an Indian Production Agency (IPA). It specifies that 16 aircraft will be bought off-the-shelf from the selected vendor while 40 must be produced in India. Of these 40, the first 16 need to have 30 per cent indigenous content and the remaining 24 must have 60 per cent indigenous content. Because HAL is already overloaded with commitments, the idea was to encourage India’s private sector also to get involved in the aerospace industry.

However, there are reports that Indian industry finds the order of 56 too small to justify the capital expenditure that would be incurred in setting up a new production line, especially in the absence of clarity about what would happen after completion of this order. And just weeks before the RFP’s extended deadline of December 08, 2013, Praful Patel, Union Minister of Heavy Industries & Public Enterprises, opposed the deal on the grounds that Public Sector Undertakings (PSUs) were being denied an opportunity to compete for the order. The IAF has since extended the deadline to March 08, 2014. However, as Mr Chandrajit Banerjee, Director General, Confederation of Indian Industry (CII) rightly points out, “Hindustan Aeronautics Limited (HAL) or any other Defence PSU, as an entity, has not been excluded from the participation in the project. Moreover, HAL is free to tie up with private sector companies who would be the Indian Production Agency (IPA).” He goes on to warn that revisiting the programme, at this advanced stage, will not only stall this project but also discourage private industry from investing in defence projects.

C27J Spartan

The Avro replacement scheme is perhaps the only viable entry-level project for India’s private industry. It is neither a strategic project nor is advanced technology required; hence it will not benefit HAL in any way. HAL has its hands full with numerous contracts and is rarely able to meet its obligations in terms of quality and timelines, resulting in huge cost overruns for the IAF. Competition serves to make the industry more efficient and will strengthen the military-industrial base in the country which, at present, is woefully weak.

Some experts believe that India’s private aerospace industry is at least half a decade away from being able to undertake complete assembly and systems integration for a medium-sized transport aircraft. Production delays are also possible since the aircraft would be produced by an inexperienced private sector company for the first time. But since the IAF has initiated the process well in advance, it would not be left high and dry.

The C-27J Spartan is also a twin-turboprop, an advanced derivative of Alenia Aeronautica’s G.222…

What Is On Offer?

With some luck, this wrangle will be resolved and the IAF can get on with the more important task of considering its options. The two main contenders are Airbus Military’s C-295, and Alenia Aermacchi’s C-27J Spartan.

The C-295 is a twin-turboprop tactical transport aircraft manufactured in Spain. It is a rear-ramp aircraft and has proved popular with a number of military forces around the world. It can carry 71 troops or a payload of 9,250 kg. It has a maximum take-off weight of 23,200 kg, cruise speed of 480 km/h, and range of 1,300 km with full payload. It is fairly close to the Avro in size and capability. Airbus Military has also launched the uprated C-295W with winglets and more powerful engines with an eye on the Indian market.

The C-27J Spartan is also a twin-turboprop, an advanced derivative of Alenia Aeronautica’s G.222. It has a capacity of 60 troops or 46 paratroops or a payload of 11,500 kg. Its maximum take-off weight is 30,500 kg. It has a cruise speed of 583km/h and a range of 1,852 km with 10,000 kg payload.

Neither of the two frontrunners has the desired cruise speed of 800km/h and range of 2,500-2,800 km. But these parameters are somewhat unrealistic, especially for a turboprop, and may need to be lowered. The C-295 is cost-efficient to operate, and the manufacturer promises large savings over comparable aircraft over its lifetime. The C-27J offers enough width and floor strength to handle loads like vehicles and small helicopters, though it is shorter than the C-295 and can carry fewer cargo pallets. Since it has some commonality with the IAF’s C-130 fleet, maintenance should be more economical. However, Alenia’s parent company Finmeccanica is under investigation for kickbacks and unless it is quickly cleared, this deal seems rather unlikely.

Most of the world’s air forces are tactical by definition…

The chances of the other contenders are even slimmer. Ukraine’s Antonov An-148 regional jet is a possibility. It can carry a mix of passengers and up to nine tonnes cargo and has a number of other customers around the world, including countries with comparable climate variations and high altitude terrain. However, it reportedly has high operating costs and some reliability issues. Russia’s Ilyushin IL-114 and Sweden’s Saab 2000 turboprops have also been mentioned. But since they are currently out of production their chances are bleak.

The Perils Of Tactical Neglect

Most of the world’s air forces are tactical by definition. Even those that have strategic capability cannot disown their tactical antecedents because a purely strategic force cannot meet the range of contingencies that may warrant the use of air power. Indeed, the bulk of routine transport missions fall within the purview of tactical transporters. While the total airlift capability of the IAF must necessarily be high, as must be the total number of aircraft available, the medium and light tactical transport segment cannot be neglected. Otherwise large and costly aircraft may be misused to transport smaller loads more suited to a tactical airlifter.

A balanced transport fleet – in which heavy and medium lift as well as light aircraft are in adequate numbers – is essential to enable the IAF to meet the wide variety and scope of tasks that may land on its plate. That is why although the service is justifiably proud of its recent big-ticket strategic airlifter inductions it cannot lose sight of the fact that it is in danger of becoming unbalanced.

The Avro replacement requirement has been pegged at 56, purely to replace the IAF’s existing fleet. This demand is contingent on sufficient MTA being produced to replace the An-32s. The MTA themselves are of higher payload capacity so the need for light aircraft may actually increase, to cater to lighter loads. In time, therefore, this Avro replacement fleet may need to be doubled. There may also be other orders, perhaps from the other defence services and paramilitary organisations, even civil regional airlines. It could eventually make a large total. However, the private sector needs to be given some such assurance in order to help the project take off.

Although it is certainly important to have an indigenous aerospace production base, a monopoly (as HAL has enjoyed so far) is not conducive to efficiency. Some private sector competition might help HAL to shape up, as state-owned Air India is doing after the entry of private airlines. However, if no foreign entity is willing to enter the Indian defence market by tying up with Indian industry, the Avro replacement process needs to go ahead in any case by purchasing a suitable tactical transport aircraft off the shelf. The IAF’s requirement is urgent and cannot be delayed much longer lest safety issues begin to emerge with the ageing Avro fleet.
