That IS impressive, but i think that would require being built-in in a fighter,
i don’t think you can fit those sensors in a pod
More information:
Hans Hellsten working now of Saab Microwave to create an industrial product of ideas. Products that can be used on different types of flying platforms. One possible platform can be Gripen.
Good, now we are getting somewhere, now just give us the name of these
“big sensors” that F-35 has but no-one else has ?
There are probably several techniques to find things that are hidden, e.g. things like Carabas:
Carabas enables foliage penetration, wide-area surveillance and automatic target detection.
The Carabas system, based on change detection and synthetic-aperture radar technology, uses the VHF-band offering unique features compared to other ground surveillance systems. Carabas pinpoints the exact position of targets irrespective of weather, light and camouflage conditions.
They cannot hide
A high-quality photograph or a microwave SAR image of the ground shows almost nothing of what is hidden in a forest or concealed beneath camouflage netting.Carabas uses SAR technology but exploits the 20–90 MHz frequency interval in the VHF band, and since our system uses this part of the electromagnetic spectrum, it observes the target area differently. Carabas signals penetrate foliage without reflections through all vegetation types and man-made camouflage.
The system can sense any concealed ordnance – trucks, tanks and artillery – with dimensions of more than one metre. The location of the ordnance is pinpointed to within one metre in real time.
and Scarab:
The Scaled Carabas (Scarab) option includes a vertically polarised lower UHF-band Synthetic Aperture Radar (at 140-360 MHz) as an add-on for the Carabas product. In an interval around the Brewster angle, the major part of the transmitted radar energy penetrates the soil.
In addition, the wavelength of the refracted beam is shortened by the refraction (to around 20-30 cm), making it possible to image smaller objects than what is possible with the transmitted wavelength above the surface. Underground imaging and detection of decimetre-sized objects – a much sought after application – is therefore possible.
The Scarab option relies on several innovative technological breakthroughs and methods for miniaturisation of the radar and antennas – enabling a full and complete sharing of radar electronics between Scarab and the original Carabas in a single compact unit.

AFAIK Saab can offer something similar as a pod solution for the Gripen NG, this was mentioned in conjunction with the Gripen IN offering to India.
I would be very surprised if the F-35 did not use similar techniques — perhaps in a different part of the frequency spectrum and a different implementation.
It only has two sensors which means that it cannot track objects below the Rafale due to the bods and wings in the way, like a MANPADS team defending the target you are flying towards.
Besides, it’s only an MLD and does not do what EODAS does.
Can it later do more with more CPU power and integration work, sure. I am in no way saying that EODAS wil never be matched, just that it has not yet.
Where are the two sensors positioned and what can they potentially see? Perhaps some Rafale experts can enlighten us?
I suspect you are overly negative in your assumptions about the coverage — perhaps there are some blind spots, but probably not more than that.
With two sensors, each equipped with a fish-eye lens, DDM NG provides a 360° spherical field of view around the aircraft.

No doubt EODAS is the most potent system out there today however it’s not really available in an operational a/c quite yet; when it becomes operational presumably the other systems have evolved somewhat further as well.
IMHO the main points of F-35 is that it has:
1. world-class sensors (including the AESA, EODAS, EOTS and a few other things…)
2. world-class sensor fusion
3. world-class stealth.
4. world-class EWS
4.5 gen fighters like Rafale F4, SH block III etc. will not close the gap, but make it more narrow, and should not be underestimated.
What is the resolution of the DDM-NG?
How does Iraq’s bread and butter relate to the Danish fighter competition?:confused:
Highly relevant — How many times have Denmark been attacked since WW2?
0, zero, zilch, nada
How many wars (and which) have Denmark been involved in since WW2?
I leave that as an exercise to the reader to figure out 😉
I think you are confusing EOTS with EODAS as they serve two completely different functions. EOTS is an advanced version of a typical targeting pod while EODAS provides 360 coverage (which nobody has).
The hard part is concept and integration. That is done. Once in production then it can & will get upgraded as funds and need dictate.
This is a far cry from 4th gen systems due to it being a completely new piece of equipment and a new integration task.
btw, A pod will never match EODAS due to size and sector coverage.

It was not that difficult, and i did not imply it eighter.
This is a moot point. Even Iran will be a walk in the park. Just send in a ballpark of cruise missile first(which NATO did not bother in Libya), and then the clean-up can start.
What!?
In the opening days of the assault on Libya, the United States and the United Kingdom launched a barrage of at least 161 Tomahawk cruise missiles to flatten Moammar Gadhafi’s air defenses and pave the way for coalition aircraft.

In addition I believe a small number of Scalp missiles were launched?
There is no free lunch.
Rebuilding existing airplanes to upgrade their kit is never easy. There will often be a need for increased electrical power and cooling, which robs power from the engine and increases fuel consumption, which reduces available thrust and range respectively.For example, simple AESA retrofits like SABR and RACR for F-16C have inferior performance to the custom-installed APG-80 in F-16E due to power and cooling upgrades in the later. But the -E required the -132 engine to keep thrust performance at the expense of fuel consumption/range, which required CFTs to offset, which increased weight and drag… 😮
True but more recent planes like the SH, Rafale and Typhoon are either built with AESA or with growth potential to handle AESAs.
This in combination with built-in systems like SPECTRA, PIRATE, etc, and reduced RCS and a few other things like rudimentary sensor fusion is the reason I feel the Rafale (latest release), SH, (and in the near future Typhoon and Gripen NG) deserve the notation “4.5 gen”.
Out of production in likely timeframe perhaps?

Perhaps not.
September 11, 2012
Senior Pentagon officials voiced frustration about the pace of Lockheed Martin Corp’s development of the $396 billion F-35 Joint Strike Fighter program at a high-level review on Friday, according to several sources familiar with the program.
Officials did not approve a comprehensive plan for operational testing of the F-35 program as had been expected.

Or perhaps Dassault & Eurofighter didn’t get the same information than Boeing had.
Nic
I strongly doubt that.
They most likely received the same information. but for whatever reason they decided to act differently.
rafael is 4 gen aircraft.
It’s Rafale not Rafael (which is an Israeli defence company).
Personally I still like to put Rafale (well at least the AESA version) in the 4.5 gen category, due to it’s higher survivability compared to 4.0 gen fighters like Su-30, F-15 and F-16. . But that’s just me 🙂
Norwegian MoD confirms that the F-35 will be significantly more expensive to fly than the F-16, however costs will be kept managable by relying more on simulators:
So the planes will fly 8000 hours per year (1000-2000 hours less per year than the F-16), and cost 915 – 1075 million NOK per year compared to 540 – 700 million per year today (all in 2012 NOK). It will be interesting to see if these estimates hold.
I read that the Swiss told US that they wouldn’t buy from US, period.
And that was a very long time ago.
Where did you read that?
It could not be that long ago since they bought the Hornets not too long ago (or am I becoming old…?)
I’m not sure if not fitting infrastructure was a reason or not. But they certainly never endorsed the Gripen- that’s a myth being propagated. This link states exactly what Boeing said when they withdrew.
I found the source of this “myth”:
Gripen Endorsed
Posted by Robert Wall 5:00 AM on Jun 10, 2008
Saab’s Gripen “would probably be a pretty good pick” for Switzerland. It may not be gushing language, but it’s how Mark Kronenburg, Boeing Integrated Defense Systems’ VP for international business sizes up the Swiss competition.
With Boeing having decided not to bid in Switzerland, the comment is going to further irritate officials promoting the Typhoon and Rafale. They were already furious that Boeing claims it pulled out of Switzerland because the partial F-5 fighter replacement wasn’t a good fit for the twin-engine Super Hornet. Gripen is the only single-engine competitor, and Boeing’s rationale was seen as aimed at undermining Typhoon and Rafale.
One of the big reasons Boeing decided not to bid was linked to the F/A-18E/F’s radar. The strike fighter is now offered only with an active electronically scanned array, but Switzerland wasn’t looking to spend the money on that capability, Kronenburg says.
Boeing’s nice words for Gripen are likely to be a rare exception, though. The Super Hornet is up against Gripen in several other markets, including Denmark and India.
I also suggest you read the the text in bold above, and think about what we know about the cost of SH (with AESA) compared to the cost of Rafale and Typhoon (with our without AESA…)
I recall Boeing leaving the competition very early (they considered to offer the SH), making a cryptic statement that “Switzerland should choose Gripen” or something similar. I recall it because it is rather unusual to suggest to a country that they should buy a specific competitor’s product.
Perhaps also Dassault and Eurofighter knew more about the budget situation at that time than what they are willing to admit.
If they got the same information as Boeing then also Dassault and Eurofighter were free to leave the race, but, for whatever reason they decided to stay in the race…
Perhaps we see that reason now?
