Its not all about the power avaliable, its also about what CPU systems are used.
The Gripen in 2000 used the pretty modern G3 delivering 7 GFLOPS.
The F22 anno 2005 used a cluster of the stoneage cpu family i960 delivering only 20GFLOPS.
F35 will in 2015 have a computer system that delivers 1-2’000 GFLOPS.
Just as a comparison an AMD computer with x86 based CPU will deliver 16 TFLOPS (that is 8-16 times the CPU power of the F35) the PSU needed is less than 1000 Watts. Yes, its a standard ATX motherboard.
So your 200KW are not needed, 3-4 KW is enough and that is easily cooled. What was impossible in 1999 or what was ground breaking performance in 2005 is what you can do with an iPhone today. iPhone 4S gives 51 GFLOPS in pure processing power (7,2 @ 200MHz and no relative drop off @ 300Mhz and the processor runs at 800 MHz). So in theory the F22 could run one iPhone 4S and more than double the capacity it currently has.
Cheers.

Unfortunately, Avenger is built for the irregular warfare role where the greatest threat is Igla-S, not combat against a sophisticated IADS.
Ah, so thats why they made it stealthy with internal carriage of 6 sdb and added SAR radar. Makes sense.

I think the exact same scenario as we discussed shows up in the video. Only difference is that some Avengers would have been lost (and the same goes for any aircraft flying over S300 and Pantsir systems). So the question remains, would you rather sacrifice drones for the high risc bombings or something that is 10 times more expensive and has a pilot on board?
They also showed a very good use of the F22 (in a similar role as the F35 could be used). But to do that effectively the cruise speed has to be at least supersonic.
Dont forget that it adds symmetry. Rafale and its twin beauty probes.
Add stealth to allow you to get close and that would be the ticket.
The one drawback for off-board processing is the lack of beyond line of sight bandwidth because Obama canceled TSAT. This limits the number of UAVs that you can use at one time. And if your task is to stop salvos of scuds which are hidden in a million square kilometers of mountainous terrain [100000 sq km for North Korea], you will need more than a handful of UAVs.
Here you go: http://regmedia.co.uk/2009/04/23/predator_c_avenger_full.jpg
It looks pretty stealthy, at least from the ground. Processing could be done on an AWACS that can share data with higher bitrates or simply by adding a larger cpu array.
Still. The F35 cant enter without riscing the pilots life. If it gets within 70 km of an active radar it will potentially be tracked and engaged at 50. (If the enemy has S300, which NK has). At least with UCAVs you can send them close enogough and dont cry rivers uf you lose one.
For bomb and surveiliance over heavily defended enemy areas I would be happier if they sent unmanned vehicles instead of manned ones. The F35 however could possibly be the “master” in that formation as long as it stays in the safer areas similar to the Gripen concept.
So what you are saying is that if the UCAV gets something like the EWS39 sensor suite it has everything that the F35 has to offer (in the attack role)? It already has the SAR and possibly some sort of FLIR that has performance close to F35 levels.
The Avenger will support the same weapons as the MQ-9, and carry the Lynx synthetic aperture radar and a version of the F-35 Lightning II’s electro-optical targeting system (EOTS), called the Advanced Low-observable Embedded Reconnaissance Targeting (ALERT) system.
Imaging is analyzed remotely in a datacenter with about 0,5 seconds delay.
So a new EWS package (and those are affordable) is all that is needed. Good. Lets get that yesterday.
@djcross: So a Predator C controlled via datalink/satellite would not do the same task equally or better than a F35 at roughly 1/10th the cost (assuming F35 costs 120m$)?
As we speak this is what the USAF are doing in Pakistan and to some extent at the Iranian border. Why should they start riscing pilots lives to solve the same task?
Just look at the endurance, 18 hrs at 647km/h! And its a colder target than any jet out there, and its most likely stealthier from the ground as well, it has similar internal AGM-payload as the F35 and if it gets shoot down then who cares? Nobody dies.
Predator C is just an example, it could just as well be the x47b, Taranis of an iteration of nEuron.
F15 is just that. “Not a pound for air to ground”. But then they found out that it could carry AGM-bombs just as well. (Software upgrades and maybe small changes to the pylons)
EF2000, F22 where made with similar philosophies but they both have agm-capabilities.
The F16 is a great example of versatility. If its lightly loaded for AA combat it will be very well performing in that arena. If it’s loaded for bombing/CAS it will do that at a decent price with good results.
:confused: Airliner engines are larger than an F-18? :confused: Since when?
The F-35 isn’t bigger than an F-18, but so what? It has half as many engines.
If you want to say the F135 is impressive, talk about its T/W ratio, or fuel efficiency, or some other category in which its performance is impressive, not absolute thrust. 191 kn for an aircraft engine is not in itself impressive. There were jets with 169 kn powering M2 aircraft forty years ago, & it’s dwarfed by subsonic commercial jet engines.
Haha. No, i meant that the F35 is shorter than a FA 18 whilst commercial airliners are not. So its impressive that such a small jet has such a large/powerful engine. The F135 is a great engine, the only problem is the high drag and heavy stuff around it.
There are commercial airliner engines with over twice that thrust.
Yeah, but they are ususally larger (longer) than a FA18 and the F35 isnt.
Msphere please enlighten us. Build us a plane that super cruises at mach 2.0
carries 30 AMRAAMS internally. has better stealth than a F-22, can land on a carrier, Gator boat, Has a 2000NM combat radius has 3d thrust vectoring and costs less than 50 million dollars. Whats is your solution to canceling the F-35? If your Not suggesting that the F-35 be canceled then why bother cutting numbers? If your not going to cut numbers then explain your reasoning?
There are two alternatives.
One is a possible “YF 23 Mk II”. Comparing the “Mk I” with F35.
[INDENT]Weapons: 8 missiles vs 4 (possible loadout for YF23 8 AIM120D+3 ASRAAM)
Cruise speed: mach 1,6 vs mach 0,95 (ok Spudman, mach 0,999 unless its in a dive)
Top speed: mach 2,2+ vs almost mach 1,65
Weight: 13’100kg vs 13’300-15’800
Thrust/weight ratio: 1,36 vs 0,75-0,87-0,9
Range: over 4500km vs 1670, 2220, 2520km
Combat radius: 1216nm+ vs 584, 469, 615nm
Stealth: Better than the F22 vs worse than the F22 [/INDENT]

So in conclusion, building a lighter jet usually is cheaper. Building a jet without politics involved (as much as in the F35 case) also makes it cheaper. The YF 23 would also be lighter today compared to 1990. Adding 3D TVC in a Mk II version should be doable.
I honestly think that was pretty close to your specs. Almost twice the F35 performance in most areas, less used materials. Will it have STOVL? No. But neither has the F35A or C. USMC can buy their own airplane/helicopter hybrids if they want, the rest of the world shouldnt pay for that.
The second, FA XX, looks like a great alternative to the F16 and FA18 but I think time and costs will tell whats best.
I know you had some exaggerated wishes but the YF23 does looks good, doesnt it?
191KN in one engine is nothing short of impressive.
Excellent posts. I will just provide some numbers for the discussion.
Remember that the Gripen platform was built around the “base 90”-system.
What this means in numbers is the following (based on Libya).
Aircrafts: 5 Gripens
Pilots: ~6
Ground personel (all included): 40
Flight hours per month: ~340
Total flight hours: over 2000.
40 persons included this:
* Stab (HQ):
* Stridsflygenhet (Fighter Unit): 6 ppl
* Flygunderhållskompani (Fighter Support Coy):
* Mission Support Element, Interpreters etc (MSE):
* Flygbasenhet (Air Base Unit): (SIS-grupp).
* National Support element (NSE):
All equipment needed (except for fuel) fit in one C-130 Hercules.
One maintenance task could not be made on site and it was a damage (peeling) to the cockpit canopy RAM-coatings on one Gripen (first time that has ever happened btw). All other maintenance, including engine replacements where made on site.
What does this mean for a regular force in a small country like Latvia, Estonia, Lithuania?
[INDENT]If Lithuania, Latvia and Estonia where to adopt a small joint AF that totals around 12 aircrafts they could all have fairly cheap forward operating bases (like the ones in FL01/02 or base 90).
So with these pretty down scaled airbases they should be able to fly 300 hours per year and aircraft and would go years without needing SwAF technicians. SwAF is a logical place to send the jets due to the loyalty agreements and the fact that its the largest operator nearby. If Gotland was opened for the Baltic countries as a “fallback” base it would be even better.[/INDENT]
I know its simplified but I just show what the numbers say. This is just if they use the FL01/02 package as their solution. Cost: ~6m$ per airplane and year. In this case 12m$ per year + personel, fuel and facilities (that can be cheap due to the STOL capabilities and low need for maintenance). There are plenty of existing airfields that can be used as they are if they only get the materials they need there.
There are a lot of old things that the SwAF dont need any more as well. Accomodation facilities, 600 meters of straight road, hangars and a storage unit + command unit is pretty much what is needed, maybe even with “guest hangars” that only have a roof.
Now just add what fits in one C-130 in the form of spares and weapons for one year + one Giraffe radar and a small commandunit (in base 90 its a mini caravan with the real command unit being under ground or at remote location).
Will this be free? No, but it sure wont cost a fortune either.
Premium hangar (can be bought at IKEA or from SwAF)
Smaller one:
I think it looks like a nice plan. Hopefully Gotland can stand as a fallback AF for quick turnarounds.
You mean deliver more like:
- A single 4-ship of F-35s can enter the defended battlespace without a circus of CAP, SEAD, jammers and tankers which a Gen 4 strike package would require. It is easy to forget about the cost of the protective circus and complain about the cost of F-35.
No it can’t. It need the same type of protection as the 4th gen fighters, only a little less.
- Use stealth to bypass IADS strongpoints? Where a Gen 4 would have to roll back SAMs via SEAD and jammer support. And how many additional Gen 4 sorties would it take to roll back the IADS? And how much do those sorties cost?
Flying under the radar can easily get you within 40 km of the targets (if radar + jets are at around 30 meters of altitude). Flying in a stealth jet you will get detected, tracked and possibly engaged within 55 km of the target (detected and tracked at over 70km) if you are at altitude. This is based on the enemy having the S300 or similar system and you flying a jet with a RCS of 0,001sqm, aka a smaller RCS tan an F35.
I think you still could get equal results or better by using “the old ways”. What gives more bang for the buck? 8 old jets with over +16 SEAD missiles or 4 jets with a total of 8?
- Use ESM and stealth to either avoid or ambush DCA? While Gen 4 requires CAP to stay alive. And what is the cost of the additional CAP?
Even the F35 needs CAP.
Again, the only difference is detection range vs radar. This is a threat most 4th gen fighter simply can avoid as demonstrated in excercises like Red flag as well as during operations like Unified Protector. The one using radar will giveaway their position first and the 4th gen fighter can take apropriate action.
- Use on-board sensors networked within the F-35 four-ship to find, fix, track and target the enemy’s relocatable kit who is using sophisticated camouflage, concealment and deception techniques? Where Gen 4 would waste munitions on decoys, requiring more sorties to finally destroy the real targets (Bosnia Kosovo lesson). And how many additional sorties are needed to kill the decoys and real targets? And how much do those additional sorties cost?
Lessons learned: Equipment that is over 35 years old is enough to engage stealth aircrafts. 1 downed F117, 1 damaged.
Against up to date air defences stealth alone wont cut it.
The engagement of decoys was also related to the ROE/Mission profile. The pilots had orders to engage all targets and not waste time trying to discriminate. Also, the US used decoys to keep the enemy SAMs occupied.
- Guide network enabled weapons to moving targets while the ring of protecting SAMs are furiously trying to stop the attack.
This is pretty standard stuff in most modern jets. Modern datalinks have these capabilities. For instance TIDLS has had it for approx 20 years. At least when it comes to shared guidance.
When it comes to the invisibility stuff its science fiction both today and tomorrow.
The only new thing in the F35 is that the avionics are top notch (that edge can be surpassed with upgrades in the other platforms if needed) and stealth that allows it to get closer to enemy radar stations without being detected. In the F35 this came at the expense of cost and flight performance. It does not have an invisibility cloak or plasma stealth. If we should compare it with cars its like having a manufacturer of a dragster saying “its impossible win a race against it”, which is true if the race is short and in a straight line. If you only compare jets in the strongpoints of the F35 it will always look like it’s a landslide victory for the F35, but if you move the comparison to the competitors strong sides it will be the oposite.
Italy’s next prime minister is vowing to cut his country’s F-35 orders too.
Netherlands : The Parliament voted to get out of the JSF program. New open bid contest.
Denmark : Open bid contest.
Canada : Open bid contest.
Korea : F-35 at a technical disqualification and given a 0% chance of a win. Trailing behind the Silent Eagle and the Typhoon.
Italy bailing out has been in the news for quite some time, but I will just add some comments to ur post.
Netherlands: Has already got one jet (or more?) delivered. They have already invested in the project and its very uncertain that there will be a real open bid contest. Once politicians start paying and getting results (no matter how bad) they tend to continue. If they bail it will be because of costs and then I believe Rafale and Gripen are the top candidates.
Korea: F35 disqualified partially because they didnt allow the Koreans to test it properly. Its not necessarily so that it was worse performing in every aspect. But it is out of the competition never the less.
Looks like they are starting to use more and more graphite based coatings.
