--------------------------New Gripen Firms Up
Posted by Bill Sweetman at 6/14/2010 1:05 AM CDT
According to Saab executives, the decision to go ahead with the Gripen Next Generation has already been taken by the Swedish government.
[...]
The MS 21 configuration is being defined - but it is now clear that MS 21 is in fact the NG, with the new General Electric F414G engine, modified airframe, Selex Galileo active electronically scanned array radar and new core avionics. It is understood that development is being quietly funded by the Swedish government.

juice stuff. thanks
Some of my pics of the Gripen Demo. What a powerful machine!
Not sure in this case, but the manufacturers tend to speak in terms of their product generation. For instance Northrop Grumman is up to their 5th generation AESA with the APG-81. The first one being the Ultra Reliable Radar concept in 1985, earliest precursor to the F-22's APG-77. The precursor to the ES-05 would perhaps be Selex's Vixen series.Originally Posted by signatory
More generally, in simplified terms a 1st generation Phased Array or Electronically Scanned Array/Antenna often refers to the building sized, vacume tube survilance radars of the 1960s and early 1970s, such as the HAPDAR and later COBRA DANE.
2nd generation systems in the late 1970s switched to solid state or transistors greately compacting the systems. Examples are the AN/SPY-1 series of the AEGIS system and E-3 AWACS.
3rd generation are todays 'active' phased array systems with compact GaAs Monolithic Microwave Integrated Circuit (MMIC) arrays integrating the transmitter and reciever on the module. Key features are substantially improved reliability and the ability to interleave modes, ie. simultaneously operate air-to-ground and air-to-air modes.
Next generation will focus on new materials, packaging and mass production technologies; GaN, metamaterials, multiple per. chip arrays, wideband antennas, low cost single chip modules costing 10s of dollars, terrahertz carbon transistors, novel beam forming techniques, and not at least huge advances in computational power, software, networking and fusion with other sensors.
Excellent paper by Lincoln Labs on the history of phased arrays: "The Development of Phased-Array Radar Technology"

Someone said the SAAF Gripen will fly just before the world cup match between Brazil and North Korea. Hope we could see on TV!!!

Payload has grown again... to 7200 Kg
What is the dotted green circle representing? The green circles are alreday finished integrations and the dotted red circles would be those integrations standing next in line to be made but what does the dotted green circle around the RecceLite pod symbolize?
Well it's integrated but not on front line divisions as far as i can tell. Was flown during the Swiss evals on SwAF OT&E Gripens if I remember correctly.
@tidls, awesome photos !
The sound of their Volvo engines would surely be an improvement - damn, I#m really getting sick of those Vuvuzelas
Nice to see Hans Rosén moving up a slot.Date Posted: 15-Jun-2010

Saab predicts increase in global fighter market
Gareth Jennings Jane's Aviation Desk Editor - Linköping
Saab anticipates a substantial increase in fighter procurement activities in the next three to four years following a recent lull brought about by the global economic crisis, according to Hans Rosén, head of marketing and campaigns for the company's Gripen fighter aircraft.
[...]
Of the 12 fighter replacement programmes that are ongoing or expected to be launched before 2016, India's requirement for 126 aircraft is seen as "the big one", Rosén said. Saab's NG demonstrator aircraft arrived in the country on 17 May for three days of hot and high trials in northern Kashmir. Flying down through Hungary, Greece, Egypt, Saudi Arabia and Oman before arriving at Jamnagar in Gujarat, India (3,300 m above sea level), the NG "performed better than even we expected", Rosén said. The aircraft, which was accompanied by 10 support staff, flew eight sorties, during which it was crewed by Swedish and Indian pilots.
"We think the IAF [Indian Air Force] has a good view of the Gripen," he said, adding that Saab believes India will need more than the 126 aircraft requested so far. Of these, 108 are due to be built by Hindustan Aeronautics Limited (HAL) in-country. A downselect of the six competing aircraft is due towards the end of this year.
[...]
Thailand, which has started training pilots for the six aircraft it ordered in 2008, is expected to sign for a second batch later in 2010. Saab sees additional opportunities for up to 36 aircraft in this country.
The Swiss, who have a requirement for 22 aircraft to partially replace the air force's ageing fleet of Northrop F-5E Tiger IIs, are being offered the Gripen aircraft based on the future MS21 upgrade (the Swedish Air Force recently instigated the MS20 block upgrade of its Gripen fleet). "Switzerland is a real hot spot for us right now," Rosén said.
[...]
Saab sees the Gripen NG as being a prime contender to secure many of the 2,500 fighter orders expected in the next five to 10 years.

Sweden awards $29.6 million contract for Multifunctional Information Distribution System terminals to Data Link Solutions
(Finland also signed a contract for MIDS-LVT terminals the day before Sweden.)
http://www.rockwellcollins.com/news/page12472.htmlCEDAR RAPIDS, Iowa (June 15, 2010) - Data Link Solutions (DLS) has been awarded a $29.6 million contract for Multifunctional Information Distribution System - Low Volume Terminals (MIDS-LVTs) from the Swedish Defence Materiel Administration, FMV. The equipment is to be used by FMV and the Swedish military. These MIDS-LVT terminals provide real-time data communications, situational awareness, navigation and digital voice capability, all in a jam-resistant, crypto-secured package.
"This contract continues a 10-year relationship between DLS and the Swedish military to meet their data link network requirements," said DLS Director Steve Overbeck.
Deliveries begin later this year and will continue through 2012. The terminals will be installed on Gripen fighters, Erieye C2 aircraft as well as various ground and maritime applications. Work will be performed in Wayne, N.J., Cedar Rapids, Iowa, and Heidelberg, Germany.

But MTOW is still the same, 16.5t - 7.2t payload - 7.1t empty weight = 2.2t internal fuel only right? But it wasn't it 3.5t internal fuel initially?Brazilian Aero Blog and Alexandre Galante was invited to the Aerospace Conference Sweden. Saab held among things a conference on the Gripen NG programs.

Payload has grown again... to 7200 Kg
Sure. There's practially no normal loadout for a 7200 kg payload but if there's ever such a need to fly a very heavy load the jet would have to fly out with less than all its possible internal fuel. It's better to be able to do it once in a while with less fuel... than not at all. Provided that MTOW is not upped in the future.
Worth to keep in mind; all jets should be looked at in more details if people intend to compare payloads... some jets talk about near 10t payloads but has still quite few weapon stations that can support such massive loads unless all they pretty much plan to do is carry fuel and the occasional strike weapon. Gripen NG a/c despite being light-medium fighters has for instance as many as 7 pylons suitable for air to ground weapons while some of the heavy twin engine jets has fewer pylons available for A2G weapons and is then limited to lighter air to air weapons on remaining stations. But at the end of the day all that matters is what the air force intends to do with their jets...

Eyes on Applied Composites AB
Taking part at EUROSATORY this week; ACAB supplies the radar cross section reducing radome for the JAS Gripen.
The company has 50+ years of microwave technology experience on how to design radomes that optimizes radar performance while reducing vulnerabilities to external signals (and mother nature). Saab Lansen was the first SwAF aircraft to use one of their radomes.
Applied Composites AB has its hand on a wide range of projects that require light weight and/or stealthy composite components. Plenty of SAAB products but also for programs such as the Swedish and Norwegian stealth vessels.
Professor emeritus Gunnar Eliasson on ACAB in his book "Advanced Public Procurement as Industrial Policy: The Aircraft Industry as a Technical University":
ACAB's Gripen Radome at Compact Test Range (CRT):
ACAB is a natural part of Swedish aerospace R&D. They for instance contributed to the National Aeronautics Research Programme - NFFP "SIGANT" program that aimed to research body-integrated array antennas.
Google-Translate from VINNOVA NFFP review
SIGANT - Hull Integrated antenna arrays with low Radar signature
Project Hull Integrated Antenna Group in Stealth UAVs were
in EMW / SMW as a pilot study, together with researchers from
Department of Electrical and Information Technology at Lund University. The project
finally reported in March 2005, one main start in 2007.
SIGANT project aims to research and development of technologies for
relevant air apertures and creep of these standby. Given
future development and flygfarkosters future tasks, including
electrically controlled antenna arrays (radar, communications, on-board
entertainment systems, etc.) to airframe integration. This technique involves
lower weight, smaller volume and, ultimately, better fuel economy. Another
important aim is that the hull can be more easily integrated antennas provide
air craft low radar signature.
Three apertures was constructed: 1) group which antennkaviteten integrated antenna
against a slotted hull segments, 2) wing-edge integrated 1-GHz antenna and 3)
airframe-integrated, frequency selective radome. EMW / SMW and ACAB stands for
Design and development of Aperture, colleges for assistance with
calculations as well as research on related issues. KTH the focus has
on antenna theory and wave propagation, while LU mainly studying radomes
wave propagation and scattering theory. By EMW / SMW has also Saab
Aero Systems and Saab Bofors Dynamics participated in the project.
ACAB recently updated their web and with that a couple of new photos of their activities:
Unidentified (?) radome at the CTR.

Holy ****! That last pic with 18 of them, it's just so...awesome! I wish I could be there to see it in person!
And that unidentified radome seems very interesting!
I spoke to two guys from ACAB the other weekend at Malmen. They had this radome and Gripen's original on display. According to the information in their display, this was a project together with FMV. I guess it was a study of possible future radomes and given the geometry it's for a future stealth aircraft.ACAB recently updated their web and with that a couple of new photos of their activities:
