Saab touts Sea Gripen for India and Brazil

December 18, 2009, 11:19:06 PM

Robert Hewson Jane's Air-Launched Weapons Editor, London

 

Saab is responding to an Indian Navy (IN) request for information (RfI) regarding future carrier-capable fighters with a new development of the Gripen NG, dubbed the Sea Gripen.

 

India's RfI, selectively released to bidders over recent weeks, seeks detailed information on a common aircraft design for conventional aircraft carrier operations and short take-off but arrested recovery (STOBAR) operations.

 

Beyond the (much delayed) entry into service of the INS Vikramaditya (the rebuilt former Russian Navy vessel Admiral Gorshkov ), India has ambitious plans to build three indigenous aircraft carriers (IACs). Near-term procurement of the MiG-29K should equip Vikramaditya and IAC 1. The IN's RfI is looking for a follow-on type to operate from IAC 2 and 3.

 

Jane's understands the RfI has been issued to Boeing, Dassault, Eurofighter, Lockheed Martin, Sukhoi and Saab. While India is notionally developing a naval version of the Hindustan Aeronautics Limited (HAL) Tejas Light Combat Aircraft, the RfI is a recognition that this troubled programme might not be able to deliver an operational combat aircraft in the necessary timescale. India hopes to commission IAC 2 and 3 in the second half of the next decade.

 

Prior to receiving the RfI Saab had completed detailed design pre-studies for the Sea Gripen in response to earlier interest from Brazil and others. In fact, designs for a navalised Gripen date back to the 1980s in Sweden. For Saab the Indian requirement is particularly important because of its potential links with Brazil's F-X2 fighter competition. The Sea Gripen would be part of the long-term industrial development package for India and Brazil, should either country select the Gripen NG. The Indian RfI also makes a specific request that India's chosen aircraft should be exportable.

 

Saab's Sea Gripen project leader is former Swedish Air Force Lieutenant Colonel Peter Nilsson, now vice-president of operational capabilities for the Gripen. "You have the Rafale, Super Hornet, even - some day - the JSF [Joint Strike Fighter], but no affordable option for nations that want independent seapower. Gripen has a built-in carrier capability that was part of the original design consideration. It is made for precision landings on a short strip. The aerodynamics, handling and landing qualities are all there. You don't have to mess with it," he told Jane's .

 

The Sea Gripen is made possible by the inherent performance characteristics of the Gripen and the structural changes introduced with the Gripen NG. It has been designed to operate from 'full-spec' carriers at a maximum take-off weight of 16,500 kg and a landing weight (with weapons and fuel) of 3,500 kg. The same basic design parameters make it well suited to STOBAR operations. Any Gripen can already operate from a standard Swedish 'roadbase' strip of 800 m x 17 m, without arrestor hooks or brake chutes. Existing flight control qualities and low approach speed make the Gripen further suited to the carrier environment.

 

Some of the changes demanded for the Sea Gripen include a stronger, longer nose gear, with larger tyres and a new shock absorber; a new main undercarriage capable of absorbing a 6.3 m/sec sink rate; a strengthened arrestor hook, repositioned from the current design; removal of corrosion risks from the airframe using new manufacturing techniques/materials; and integration with an approach/landing system.

 

The result will be an aircraft with an empty weight of under 8,000 kg with a total fuel and weapon load of around 8,500 kg. Combat radius is estimated at around 1,250 km in a maritime strike profile or 1,400 km in an offensive counter-air profile. For carrier operations the aircraft will have a service life of 8,000 flight hours with an even distribution between shipborne and land-based operations.

 

Nilsson says the design work done so far has been a serious adjunct to the Gripen NG and has a very real footing. Asked about the inherent difficulties in taking any land-based fighter and putting it on a carrier, Nilsson replied: "If you were starting with an ordinary fighter you would have a much bigger problem."

 

"We have an engine [General Electric's F414] cleared for naval ops by the US Navy. We have thoroughly studied the load paths through the airframe. The Gripen is already built for high sink-rate landings in road base operations. So we need a new nose gear and undercarriage and we'll have to change some of the internal structure, but it's been analysed and it's possible. We built an arrestor hook into the Gripen NG proposal for Norway. That will have to be strengthened for carrier ops, with a new attachment point, but the work is there. Today's Gripen NG has a better wing attachment design with a more distributed load path than the current Gripen.

 

"The Gripen already has a salt water protection requirement. It does need more study but we already have an aircraft designed to operate in -50°C and +50°C, from the Arctic to hot-and-high with severe humidity. We don't build fighters for nice sunny days."

 

Saab expects to make initial presentations to the IN in January 2010 and submit an RfI response the following month.

Navy plans to acquire multi-role fighter aircraft

Ravi Sharma

 

BANGALORE: Looking for an enhanced presence, the Navy is planning to buy a state-of-the-art, multi-role, new generation carrier-based fighter aircraft. And in pursuance of this, the Navy has sent out a request for information (RFI) to some of the world’s leading aircraft manufacturers.

 

The aircraft firms included: the European Aeronautic Defence and Space Company (EADS) for their Eurofighter Typhoon, the Boeing Integrated Defence System (for the F/A-18 Super Hornet), Sweden’s SAAB (who are offering the Gripen JAS 39) and France’s Dassault (for the Rafale).

 

The new naval aircraft are meant for deployment on the Navy’s third aircraft carrier, which is expected to be commissioned around 2018.

 

While the Rafale and the F/A-18 are natural choices for naval operations as they were built specifically for carrier-based multi-role operations, the manufacturers of the Typhoon and the Gripen have indicated that their aircraft could be suitably modified for naval carrier-based flying.

 

All four aircraft (along with the Russian MiG-35 and the American F-16) are already in contention for another mega Indian defence forces’ deal — the $10 billion -$12 billion Indian Air Force’s plans to acquire 126 medium, multi-role combat aircraft.

 

The Ministry of Defence sources told The Hindu that the Navy has the go-ahead from the government for the purchase. The RFI has not specified the exact number of aircraft that the Navy is keen on acquiring, nor the modalities that will be specified for their manufacture or offset requirements.

 

Once the manufacturers provided their information, the Navy will send out a request for proposal detailing the Naval Staff Qualitative Requirements that the fighter should possess.

 

After the receipt of the proposals, the Navy will short list, setting in motion the process of flight evaluation trials, selection, commercial negotiations and finally the acquisition.

 

The new aircraft, which will be in the 25-30 tonne class, will be in addition to the 16 Russian-manufactured MiG-29Ks that India is acquiring, and the naval version of the indigenous Light Combat Aircraft Tejas (12-14 tonnes class) which is presently being designed.

 

The Navy on December 4 received in knocked-down condition, the first of its MiG-29Ks.

 

While the MiG-29Ks will be on the deck of the 44,570-tonne Kiev class Admiral Gorshkov (to be rechristened INS Vikramaditya), the naval Tejas is earmarked for the 40,000-tonne, indigenous aircraft carrier that is being built at the Cochin Shipyard.

 

The Navy’s only fighter aircraft now is the British-made Sea Harrier jump jets which are deployed on the Navy’s sole aircraft carrier, INS Viraat.

 

Official sources said that the Sea Harriers, which were decommissioned by the (British) Royal Navy in March 2006, will be in the inventory as long as the INS Viraat is deployed (could be till 2019).
