I think a 50% increase per year in production is a good plan. LRIP 6 is the first Block3i. Block 3F is on schedule to be completed by 2017
50% a year would only increase your 40 jets to 135 in 4 years.
yr1: 40
yr2: 60
yr3: 90
yr4: 135
‘Tis nearer 60% year on year. That is probably not sustainable for (at least) some specialist companies within the supply chain. The kind of qualified people needed to build these types of equipment just don’t grow on trees.
Interesting graph, why does it take LM 4 years to ramp up the production to over 200 a year? Are they not confident of the dynamics of the supply chain and the capacity of the line? Secondly what Blocks will Fort Worth be producing? As I understand it the hardware for the post tech refresh has been designed but there are major issues with the software to run the hardware. Serious Concurrency issues.
To only quadruple production in 4 years*? That is an astoundingly aggressive ramp and one which they undoubtedly won’t meet (at least, while maintaining quality).
*Including incorporating the lessons learned from testing?
Any thoughts or opinions on the change of EADS to Airbus group?
There was a thread elsewhere that touched on it.
I think my conclusion there was “the devil makes work for idle hands”… i.e. EADS need to gut their marketing department. Too many overheads looking to justify their continued employment.
On hindsight the decision was a wise one.
In hindsight the decision worked (very) well for them.
I still don’t agree with it though. In an uncertain world (early 90s), they made the decision to decreased the sphere of influence of the carrier and decrease its air defense capability.
That it worked well probably shows they’ve more foresight than me. Or were bounded by greater political/monetary influences than I appreciate. Or both.
This is of course why people laugh at forums like this. It is loaded with self proclaimed experts whose analysis inevitably boils down to “is this a plane I like?”
If you can’t be bothered to read what people are talking about you might as well spare us your ignorant comments. It isn’t like you are going to fool anyone into thinking you know what you are talking about when it is 100% clear you don’t.
Great, we have the expert opinion of the same guy who “sniggered” at the thought of the CFTs reducing drag just a day or so ago… :rolleyes: :very_drunk:
The fact is you don’t have a clue how a Super Hornet with CFTs and the enhanced engines would perform but as usual you are just spouting off. Certainly it would be slower than a Super Hornet with the enhanced engines and no CFTs… but it would almost certainly be faster than the current Super Hornet.
1. It is a PR presentation. It is barely worth reading. If someone rolled in here using 1 test point for performance characterisation I’d laugh them back out the front door.
2. Read my original post again. It seems you equate me to thinking negligible drag rise was impossible, whereas I started out saying it highlights how bad the original was.
3. That the subsonic drag is insensitive to the addition of two massive volume (and wetted area) increases along the spine indicates: “The original aerodynamics of the subpar-Hornet are even more crap than I thought.”
4. That the Boeing official(s) chose to highlight this change (or non change) at a point where performance is not critical indicates “The Boeing official is a bullsh!tter of the highest order”.
5. Much more informed and intelligent people than yourself are content to pay me a great deal for consultation on matters relating to aircraft aerodynamics and structures. Whether that means I know what I am talking about is up to them. But they do keep coming back and it does keep me in beer-money.
I guess you better call up the various F-15 and F-16 operators who use CFTs and let them know they have it all screwed up. :very_drunk:
Who ever said the CFT designers screwed up?
If the F-15/F-16 CFTs had no detrimental performance on the aircraft, I’d call up the original designers and tell them that they screwed up.
Of course there are tradeoffs when you add CFTs to a jet, but for the most part they are modest and outside of messageboards range and endurance are almost always more important to operators than shaving a few seconds off of a hypothetical drag race.
Drag races and energy bleed cease to be hypothetical when it comes to getting out of the way of a SAM or AAM. Especially when you cannot quickly regain “clean” performance mid-mission.
Although, I suppose that is the difference in the USN when it chose to go with the SH rather than updated Tomcat.
The F-14 kept the carrier safer from air attack.
The SH made the carrier cheaper to operate.
Pays your money and takes your choices. Personally, if it had come to it, I’d have dropped a deck and used the extra money to get the updated Tomcat. Better to have 10 carriers with more effective air defense and payload-range attackers than 11 with marginal. Although to add to that the end of the cold war no doubt came into the Navy’s decision making. Their thought train no doubt being “Do we need the best possible air defence and heaviest strike when the Backfires are doing no more than gathering rust and all we are doing is dropping bombs on lightly armed mobs?”
Look at slide 11 where it is very clear what the test conditions were, .84M and 34k feet. Those are cruise conditions and are very relevant to discussion of drag/efficiency as that is where all fighters spend the vast majority of their time and fuel.
Nah, I didn’t bother to look at the slides.
~M0.8 is at the start of the transonic envelope for a fighter; therefore there is no difference in lift mechanism between that and M0.5. If you increased the speed of the test to M0.9 I would put down money the results would be very different as wave drag starts to rise.
[Note, if that is not the case – then just what the f**k were the original aerodynamicists at when they designed the SH?]
The tanks will certainly impose some penalty at higher speeds, but if that is a concern the uprated engines can more than offset that.
Unlikely. Very, very unlikely. Drag increases to the square of speed for constant Cd.
Cd here will no doubt jump due to the mach-area compromises of the CFTs.
Don’t forget, in a warzone, a pilot won’t hesitate to drop an empty external tank (and even munitions) if they badly need to step on the go-go juice. Thats not really an option with CFTs. Therefore you could expect a non CFT SH to accelerate quicker through M1 than a CFT SH when it matters.
eagle and hornet are too last gen
possibly eurofighter and rafale toobut F-35 is current gen but might not have the legs to cover Canada’s huge vastness..
Don’t get caught up on the marketing speak that is “generations”.
It is by-and-by-large a lot of marketing crap*.
Better off paying attention to actual capabilities, operating costs and to expected production runs.
*For instance 1, is the F-22 5th generation because it can super-cruise? If so, what does that make the F-35?
For instance 2, is the F-35 5th generation because its network-centric? If so, what does that make the F-22?
Now, regarding KS-P/KS-U. It does seem indeed that the nose KS and tail KS has the same number of windows and same style of them. Hence it is either:
a – Both are same system, KS-U.
b – Nose one is still KS-P, although it looks the same as tail one from external POV.
c – Tail one is not complete and will have more windows so the alikeness is only illusion for time being.I think i will send him a PM and see if he can clarify the issue and if the nose one is still KS-P or if he was mistaken. I found the “evolution” comment weird too.
Both operate in different thermal regimes; which may require different internals.
Transonic acceleration is less important than cruise efficiency on a standoff jammer and SEAD aircraft, which is the configuration shown above.
The drag comments are not exclusive to the EW variant.
I am always surprised at just how quick people around here are to make fools of themselves.
Ugh. :rolleyes:
Yes… cruise L/D at Mach 0.5 really matters ‘cos fighter performance is critical in that part of the performance envelope.
Having to deal with clowns that cannot separate the wheat from the chaff is one of the most annoying things about this forum.
Where it matters – drag will either be markedly worse (which is undoubtedly the case) than an already bad airframe, or the original SH aerodynamics are astoundingly rubbish.
An official polishing a turd may fool some clowns on here and F-16.net. It’ll not fool too many that have even the most rudimentary understanding of aerodynamics and of what areas of the performance envelope are important.
Tbh, journalist probably made a mistake reporting…
True… but why spoil the fun 😉

I see the drag claim and laugh. It can mean only 2 things:
– The Boeing official is a bullsh!tter of the highest order
– The original aerodynamics of the subpar-Hornet are even more crap than I thought.
Being semi-serious, I would have thought it possible that the drag could be better because they have been able to mount 4 AMRAAM without having to use those horrible canted inner pylons… but apparently the drag comparison is between clean aircraft.
On the economics side of things, i would recommend buying a Global Hawk – Lite, and lesser number of F-18E/F’s. The GH Does your long ranged / loiter ISR mission, while the F-18E/F sits on the ground saving operational cost.
Why not do it properly and deploy airships?
I would still pick F-106 in Canada’s case, what a perfect streamlined beast with a spanky new engine
Meh. Why take the risk when the MiG-31BM would do that job better and probably cost less?
Hmmm.
Just thought of the perfect jet for the Canadians. Its:
– 2 engined for safe peacetime flight over the large expanses.
– Will have extremely long range.
– LO for survivability.
– Can supercruise at high altitude (for additional survivability).
– Can go toe-to-toe with any combat aircraft in the sky in WVR.
– Probably won’t cost as much as an F-35 (at least, in terms of purchase cost).
Can you guess what it is yet?
