Re: F-35 Joint Strike Fighter Thread

No, thunder, the pricing projections are not a joke. Neither could they be. They are constrianed by significant US law to give accurate, documented portrayals of their costing.

They are not there now, but they will get there. The price has been steadliy dropping and will continue to do so.

Do you know any fighter aircraft in US inventory that was cheaper in the middle or at the end of its service then at beginning ? Maybe some of the piston engined fighters from WW2, but jets - no Sir . Yes, there is the factor of inflation, but also equipment is more complicated , parts are more expensive etc . To put things in perspective , there were over 15 000 P-51 built, over 5000 F-4s and under 200 F-22s . Air forces all over world are getting smaller while planes are getting more expensive .

F-16 flyaway cost in 1975 was somewhere around $5-6 million . Today, F-16 Block 60/61 are over $60 million . Official inflation from 1975 to 2014 is 442 % (

) . Therefore, F-16 today is more then twice expensive in 1975 dollars . Same thing would happen to F-35 if it becomes F-16 of 21st century .

F-35s deploying to US carrier in November might not be fully operational
By: DAN PARSONSWASHINGTON DC Source: Flightglobal.com in 5 hours
Plans to test a Lockheed Martin F-35C aboard a US aircraft carrier in November are on track, but both aircraft scheduled to deploy to the Pacific may not be capable of taking off and landing from the ship.

The C-model F-35 will be the US Navy’s carrier-based version of the jet and will be the last to enter service in 2018, following the Marine Corps and air force variants. Lt Gen Christopher Bogdan, speaking at a meeting of the programme’s joint executive steering board in Oslo, Norway, said the deployment to the USS Nimitz in the Pacific Ocean was on track despite lagging software development and flight restrictions resulting from a June engine fire that damaged an F-35A prior to a training flight.

However, work is ongoing to determine if both aircraft slated to deploy will be fully capable of performing carrier launches and landings, Bogdan says.

“We have some work to do as we lead up to that point in November,” he says. “That work we’re doing now will decide whether both airplanes that go to the ship will be capable of doing arrestments and catapult launches or only one of them will be and the other airplane we will leave on the deck to do logistics testing.”

“The November deployment will happen. It will most likely happen with two airplanes. Whether both airplanes will be fully capable of doing all the work remains to be seen,” he says.

The JESB convenes every six months and includes representatives from the F-35 joint program office (JPO), all three US military services that are buying the jet and acquisition officials from the programme’s eight partner nations. The September meeting was overshadowed by a recent US Government Accountability Office (GAO) report criticising the JPO’s estimations of the lifecycle costs for the aircraft.

“The annual F-35 operating and support (O&S) costs are estimated to be considerably higher than the combined annual costs of several legacy aircraft,” the GAO report says. While the F-15C/D, F-16C/D, AV-8B and F-18A-D will cost a combined $11.1 billion over their service lives, the F-35 will cost $19.9 billion, the report says. While the Defense Department has begun cost-saving efforts to bring total per-jet lifecycle cost down, the JPO did not base its current assumptions on the service’s actual budgets and therefore “may not be representative of what the services can afford”.

“In addition, DOD has not fully addressed several issues that have an effect on affordability and operational readiness, including aircraft reliability and technical-data rights, which could affect the development of the sustainment strategy,” the report says.

Bogdan says the GAO was given eight months of open access to the JPO’s records to form its analysis, but dismissed the criticisms as based on assumptions that could “greatly change” within the 50-year service life of the aircraft.

“From my point of view, as the director of the F-35 programme, I am less concerned about cost estimates that occur 50 years from now, because those are based on a whole lot of assumptions and if you change even a little bit of those assumptions, those cost estimates change greatly,” he says.

“What’s more important to me is what we are doing today, when we have 150 airplanes, to reduce the overall lifecycle cost of the airplane for when we have 3,000 of them.”

Plans to bring the per-aircraft cost down to $80 million by 2019 are heavily reliant now on a production ramp to fulfill international orders.

Despite recent setbacks, Bogdan says current partners and potential foreign military sales customers remain committed. Discussions with Israel to increase that nation’s buy are progressing and could be finalised within months, Bogdan says. Norway’s first two aircraft are in assembly with delivery scheduled for late 2015.

“We have other nations out there who have been interested and are discussing potential buys of the F-35 despite the fact that we have an engine setback or in the past we’ve had some software problems,” Bogdan says. “Most of them look past those immediate problems because those immediate problems are not unlike anything you’ll find in most any airplane development programme."

Re: F-35 Joint Strike Fighter Thread

Not really. Using stealth is like being dressed in black, trying to sneak up on someone in the dark. Using jammers is like pointing flashlight in someones face trying to blind him . Mutually exclusive in most cases .

Using the flashlight analogy is too simple. But fine:
1) it is dark (otherwise you wouldn't need the search light (radar))
2) someone is dressed in camouflage (stealthy airframe)
3) you finally manage to see something that looks like a human (stealthy airframe) and not a bird (other irrelevant radar returns) or something that moved by the wind (erroneous radar blips)
4a) you get blinded by a strong light so you lose track of that human for a while (on-board jammer) and when your eyes get used to the sudden bright flash of light (jammer), the light is turned off again (jamming turned off to prevent home-on-jamming missiles/trackers and to try and be stealthy again). It takes a while before your eyes are used to the darkness again and you are trying to find that human again.
4b) what happens with 4a but when someone else flashes the light (dedicated jammers).



Well, F-117 was not used for air combat, F-35 will . F-35 is Joint Strike Fighter , but unfortunately it will be used in air to air role, especially in some smaller airforces . As for usefulness of supersonic speeds in air combat, volumes has been written about it (yes, it is useful if you know what to do ) .
Well, there are also volumes written how useful stealth is too, if you know how to use it.


Israel wants new planes, same as Gulf states . No new F-15s are being produced (Silent Eagle unfortunately getting slashed) . Also , F-15E (F-15I) is somewhat inferior to F-35A in strike role, I admit that . So what could Israelis do ? Lobby for restart of F-15 production or get some F-35s for free? On the other side, Gulf states are paying for their equipment, so they have other options (Typhoon, Rafale etc .. )

To my understanding the Eagle line is still open due to the SA variant. The F-15SA is the most advanced variant produced and that's why Israel is complaining. If the Gulf states are allowed to buy (non-downgraded) F-35s, then they too would view it as better than the Typhoon etc. In the article which you earlier provided, the author explained why those Gulf states are not yet deciding on buying new fighters yet, because they want to see if they get their hands on the F-35.



They complained to get best US has to offer for free in that time. Compared to F-16s and F-15s with mechanically steered radars, F-35 is somewhat better, I admit that . Had US upgraded F-16s and F-15s with AESA and some other things from F-35 program, maybe they would want that .
1) you really think that current flying, fatigue-suffering F-15Cs and F-16Cs are worth upgrading and sending your pilots into combat with them?


They are producing parts and upgrade kits, not new airframes .

The Saudi buy of F-15s carries the company’s production line, based in St. Louis, through 2018. A
Also, Singapore is also buying (anonymously) new Eagles. So that line may well last beyond 2018.

Projected cost of F-35 is a joke, especially after this unplanned engine changes . US was paying over $120 million per plane in 2013 , without engines and spares .

When starting the production line, those first builds are always going to be more pricier than when the line is up and running. How many F-35s are flying? Not fair to compare to the multitude of F-15s etc. currently flying.


Speed, maneuverability ...
The F-22 which you've brought up a couple of times has demonstrated that in order to achieve stealth, speed and maneuverability is not per se sacrificed. The question is: was the US correct in assuming F-16-like maneuverability is sufficient for the F-35? LM is a commercial company, they won't build a fighter that is much much better than what's preferred or even required. Imagine the problems they'd have if they not only need to build an airframe that satifies the needs of the USAF, USN and the Marines, but also be better than the F-22.

Jammers have been developed to confuse AESA radars too, it is ongoing battle . Also, Mig-21 were downed by Mirage III or F-4s , yet they managed to score simulated kills on F-15s . Therefore, Mig-29s that lost from F-16s could potentially defeat F-35 with right avionics .
1) Yes they'll be able to be jammed, but not yet by that Mig-21, yet. Not many countries besides the US can produce AESA radars, let alone the jammers.
2) The examples you've brought forward show that more maneuverable opponents can be beaten by less maneuverable opponents. This is consistent with what I've claimed: the F-35 does have a chance in WVR even though it may not be as maneuverable as other airframes. As a matter of a fact: thanks to its stealth + the ability to jam the F-22s radar, only the F-35 has a realistic chance to get close/ WVR and fight the F-22 in a dogfight. Other fighters should've be blown out of the sky before it comes to that.

Re: F-35 Joint Strike Fighter Thread

Actually Stealth + jamming is a super lethal combination
attachment.php

look at the picture , reduction of RCS by only 50 % mean jamming can achieve same effect with 50 % less power , and the burn through range reduced by 25% , and how much the F-35 RCS compared to su-30 or F-15 ? ( 0.001 m2 vs 10 m2 )
which mean reduction by factor of 10000 ( just look at the number and you can already imagine how much more effective jamming will be when you are in a stealth fighter

if you cannot imagine it look at the picture below
attachment.php

DDG-1000 destroyer's RCS is 2500 times less than CG-47 , thus with same jamming power of only 100 W it been able to reduce missiles seeker burn through range by 58 times
F-35's RCS is 10000 times less than su-30 , F-15 ( do the math yourself )
also F-35 can use MALD-J , FOTD or APG-81 to jam enemy radar , so it's jamming ability is actually not very limited

Re: F-35 Joint Strike Fighter Thread

I'm not trying to start a fight, but I would really want to know why do you (and all the other supporters of F-35) think it would be a game changer : it is not fastest nor it is most maneuverable, it wont be stealthiest and will not have best avionics . Last but not least , it won't be inexpensive .

speed and maneuver are alot less important than LO and SA , and to be fair i dont think any other aircraft have better LO and SA than F-35.
in fact high speed are not always good:
according to many critic of f-35 then the most important thing for fighter is kinematic ( fly high , fast , agile ) right
EF-2000 is one of the best in kinematic aspect :
The time it takes for a missile to lose 25% of its velocity after burn out at supersonic speeds.

Never @ > 100,000 m (~300,000 ft) ; in space
~150 seconds @ 24,000 m (~80,000 ft)
~70 seconds @ 18,000 m (~ 60,000 ft)
~25 seconds @ 12,000 m (~ 40,000 ft)
~10 seconds @ 6,000 ft (~20,000 ft)
~5 seconds @ Sea Level



so let assume the EF-2000 and a f-35 flying head on at 60K ft , assume EF-2000 supercruise at mach 1.5 while f-35 alot slower may be mach 0.9- mach 1 . Due to advantage of stealth f-35 will alot more likely to attack first , it launch a AIM-120D at the EF-2000 ,now since F-35 is very slow let assume it can only accelerate to mach 1 before launching the missiles , so with launching speed of mach 1 (from f-35 ) and when firing from stand still aim-120 reach top speed of mach 4 , so top speed of the aim-120 when it fired from a mach 1 aircraft is about mach 5 . Since it take ~70 seconds at 18,000 m (~ 60,000 ft ) for missiles to lose 25 percent of it's speed ( assume it fly without thrust ) , the aim-120 will have to fly for 70 sec ( about 100 km ) before speed reduced to mach 4 ) , if the EF-2000 was supercruise at mach 1.5 then the closing rate between it and the aim-120 will be mach 5.5 , assume the IRST on EF-2000 detect the missile from 20 km then the pilot will have : [20/( 1234*5.5 )]*60*60 = only about ten second to maneuver or eject or what ever
the situation will be even worst if the missiles was Meteor (higher sustain speed due to ramjet engine ) or a CUDA ( the design make it turn better at high altitude )
if you want the EF-2000 to fly at lower altitude ( dive down when he detect the missile ) then it will be worse because the f-35 will now have the advantage in potential energy for it's missiles
you can see that the faster speed really doesnt do anything good if enemy attack you first , in fact it make situation worst because it much harder to turn away , reduce reaction time , and remember with jamming from MALD-J , FOTD , APG-81 then enemy aircraft may not even have a chance to attack f-35

I found about the deal with South Korea, posted: http://www.sinodefenceforum.com/world-armed-forces/rok-military-news-12-6304.html#post306440

actually lots of older aircraft have benefitted from life extensions, it is quite amazing what can be done to extend the life of aircraft such as Spar Straps, Riveting in Gussets on attach points, these aircraft have been well maintained, but they work very hard for their living, the USAF will find a way to take care of their birds and the ThunderHoggeII will be along very shortly to pick up the gauntlet, so really, lot of peoples aircraft are in much worse shape than ours????? really, and lots of aircraft are flown with operating limitations of many different natures!
