Without nukes on those cruise missiles though how much damage could they realistically do (both because of warhead types and numbers)? Do they even have BLU-109 equivalent penetration?
I doubt. I think a Harpoon (or the cruise missile version), carries some 1000lbs (or even less, maybe only 500lbs). Anyways, to penetrate the enrichment facilities in Natanz you need BIG stick.
In a study released by two M.I.T. graduates they assume a strike would need something between 20 and 30 GBU-28 warheads. One GBU-28 is 4000lbs!
The other targets are less difficult, but the Uranium enrichment is large, buried and hardened.
This board is not short of know-it-alls….now come on. Help me clarify some stuff. My brain alone can’t solve this question. 🙂
I have a copy from a flight manual for F-4C, revision date 1967. I just list the stuff:
Air2Air:
AIM-7D/E
AIM-9B
Air2Ground – Guided:
AGM-12B/C
AGM-45A
Air2Ground – Bombs:
BLU-1/B Fire Bomb
M116A2 Fire Bomb
M117
Mk81
Mk82 (+SnakeEye)
Mk83
MC-1 Gas Bomb
MLU-10/B Land Mine
M129E1 Leaflet Bomb
Air2Ground – Rockets, Stuff:
LAU-3/A & 10/A
CBU-1,2,24
SUU-16/A 20mm Gun Pod
Air2Ground – The Bomb:
B28 (thermo nuclear, tactical/strategical, 350 to 1450kT)
B43 (thermo nuclear, tactical/strategical, 70 to 1000kT, especially for low altitude lay-down, lowest yield is fission only)
B57 (pure fission, tactical lightweight, 5-20kT)
Nice looking machine. Cuddly koala-nose.
So… anyone care to bet if the extended fuselage variant is proposed before, or after the initial deliveries are completed?
If landing requirements are eased, I think there is some fantasy in the A400M. Maybe even on the civil market. The Hercules didn’t really score any civil success back then, but the Hercules was also smaller, a bit slow and fuel prices were in the single digit dollar area. Would be interesting if there is interest in the cargo market for an A410F (stretched A400M).
Well yes, that would be a good reason to bolt on a gun turret on to it… would look a lot cooler if the gun turret was in the nose though…
Any chance of a “gunship version”, a la C-130 Spectre, that would be just as cool?
For the RAF maybe a vintage version having some resemblance to a Short Stirling might sell.
Why would you order one with a tail gun turret, what use would it be?:confused:
No use, just for fun. Just had to think of the Soviet designs from the 1950ies that all had a tail gun.
Contrary to popular belief around here, yes, the Blackbird was the first generation of stealth technology designed to reduce radar detection range. Now duck and cover because that one will get people riled up 😀
I guess the misunderstanding comes from different look on stealth. The laymen think it must be invisible. The SR-71 surely is not invisible.
But an SR-71 must basically be hard to track from forward down, the most likely angle a SAM would attack from. The high speed and altitude makes it immune from rearward attack by missiles.
Likewise the F-22: Being unstealthy from rear hemisphere does not really matter in most situations.
Now people might argue that any detection will increase the likeliness of being shot down by other assets, for example directed fighters. That is true, but if 20 F-22 attack there is hardly the time to vector each fighter into WVR attack position.
1MAN (and his alias “diaonis”) are the reason the “ignore” feature was invented.
Concur!
@BIO:
Don’t waste you valuable time fighting forum trolls that not even write a single reasonably correct sentence.
Then you should read the source material which seems to make it quite clear that the F-22 can not do mach 1.7 over it’s entire combat range of 800 Km’s on external fuel. Sure it can be refueled but so can others fighters that costs 4 times less with similar general performance margins. I could not find the data that shows as much but as i recall both the Su-27 and F-15 can fly at high supersonic speeds for at least as much time as the F-22. If you can bring sources that show otherwise ( the magical super cruising engines that does not burn fuel) i would be more than happy to accept them as i am not happier than you are that the American people are paying trough the teeth for something that does not even beat the F-15 in high speed dashes or in range.
What exactly does this confusing cloud of ASCII elements exactly tell us? Not muc i fear.
F-22 can not do mach 1.7 over it’s entire combat range of 800 Km’s on external fuel.
I think nobody ever argued it could. Why external fuel?
others fighters that costs 4 times less
Deducting the non-recurring development costs, the F-22 cost about 50 to 100% more than a Eurofighter (depends how you want to look at it).
By the way: 4 times less, how can I calculate that? One time less would be 100% less. Pretty good price, 4 times less would be minus 400%, that means, you actually earn when you buy it. 😮
Su-27 and F-15 can fly at high supersonic speeds for at least as much time as the F-22
Again, nobody argued otherwise, as high supersonic speeds normally start at M1.9ish, the limits here are temperature. But who cares about time at Mach 2?
does not even beat the F-15 in high speed dashes or in range.
In normal configs the F-15 hardly exceeds Mach 1.9.
Seriously, are you drunk?
There is NO way I believe 40 minutes of Mach 1.5!!! That is Soviet-style propaganda.
And Superman’s farts make him go hypersonic …
And these M1.5 @ 80%? Does it have to shut down the engine to land?
Given the specific range that would require 14 to 18klbs of fuel, or basically the whole loaded gas. The aircraft was ergo topped up, dive-accelerated to supersonic and stayed there until 2000lbs were left and re-attached to the tanker. That all in an area where at any given time an airport can be reached gliding.
I would like to know if one can order it with a tail gun turret.
???
Dead simple: distance = speed x time
time = 7 minutes
speed = 860kts
distance = ~100nm
A 7 minute dash is 100nm , 7 minutes of dash would be 3.5 in and 3.5 out but without any loiter time so its 50nm radius if we are not factoring in any loiter time i radius which is usually not the case so for the raptor the range compared to the 100nm of the F-16 would be 200nm @ mach 1.5 but also in addition to that the raptor would be able to go 600nm subsonically . This is ofcourse assuming RADIUS of ACTION = 2 x Range but IIRC it also usually factors in Loiter time , some i know use the 2.5x conversion factor and some even use 3x conversion factor but to be same i have used 2x conversion factor.
For an air superiority mission it is usually cruise-dash-combat-dash-cruise in a hi-med-hi or hi-hi profile. I guess the stated radius is for hi-hi. The critical thing is the combat fuel allowance, normally 3 to 5 minutes at maximum thrust (that is with reheat) or several turns at given Mach number. For the conversation of range into radius I think 2.5 is good factor for such a mission, if the range already includes reserves and climb.
So in reality the Raptor can do Mach 1.5 for twice as long as the F-16 and still have reserve to do 600nm in subsonic or do around 600nm at mach 1.5 which would be 6 times more mach 1.5 flight then the F-16 . If one was to compare @ speeds of around mach 1.2-mach 1.3 the raptor would most probably do even better and this is with a full load of weaponry even with 2×1000 lb’s these figures wont be effected by much , but we cant say that for the f-16.
You don’t have to defend it, I have said nothing negative about it.
I think specific range for lower Mach numbers will not look significantly better, maybe even worse.
It is rumoured that the F-22 does mach 1.5 @ 80% dry thrust.
Which is fun as nobody knows what exactly 100% is. The stated M1.72 are not something Lt. John Doe flies in his standard F-22A. In normal operation engines are limited for safety and cost reasons.
the supersonic speeds come with a price, the visible drop in specific range. However, cruising for prolonged distances supersonic is an advantage, and its ability to go farer at higher speed is nearly unequaled.
41 minutes on Mach 1.5 (groundspeed: ~860kts) equals 590nm range. Doesn’t exactly look like an operational figure (according to the specific ranges the remaining fuel afterwards is barely enough to reach the next tanker), but even two thirds of it is a good achievement.
Fun fact: the stated 7 minutes an F-16 can go are exactly the 100nm that are listed in the “default mission” of the Raptor.
The goal of U.S has NEVER been stability in Iraq, but the divertion of Iraqi oil to Isreal, your wasting your time believeing these fantastic explainations of why Iraq was invaded.
Oh. I thought they invaded Iraq because the secret alien mastermind* has ordered it. I found this explanation very logical.
————–
*that alien mastermind that runs all US administrations from secrecy and uses presidents as his marionettes.
And Israel is in no position to tell another nation they cannot have nuclear weapons. Neither is the United States. Nor is Russia. Next.
Isn’t the whole idea of the non-proliferation treaty about making the club most exclusive? I think if there was something the USA and USSR always agreed about, then it was that the nuclear club needed to be small. France and England was acceptable, as they did rarely behave differently than the USA (in global questions).
China was less acceptable, so was India. Israel limited its ability to the region and did not have any ambitions in the region (except for its very own survival plus security perimeter).
China, Russia, USA, Europe, Saudi Arabia and Pakistan all agree that Iran neither needs nuclear weapons, nor needs the ability to produce them (Japan, for example, is allowed the ability to produce nuclear weapons, so is basically Germany, too, or some other “nuclear nations”). Where the limit for its nuclear industry exactly is not agreed to the detail, and what kind of sanctions are to be used.
The more interesting question regarding “Mission 1” is at what altitude? The Stevenson’s slides show a SR of ~0.075nm/lb at M0.9 at 45K and a SR of 0.04nm/lb at M1.5 at 45Kft. Going w/ those numbers that burn about 11,200lbs total for 360 + 100 which leaves about 7,000lbs for 1 minute of blower + reserves; this seems about right. Now here’s the kicker; AvLeak reports that the F-22 routinely operated at 60+Kft during NE and RF exercises and Col. Showers comments – before they were removed on fencecheck – supported AvLeak’s reporting.
A very rough estimate shows that at M1.5, fuel burn drops almost 50% from 45 to 60K so we’re looking at a supersonic SR of roughly 0.08nm/lb; IF the relationship stays more or less true for the F-22/F119. That alone would double the supersonic segment and now you’re looking at close to 360+200nm radius of action. Interestingly with such efficiency, one could come off the tanker (assuming you’ve topped off) and go 800+ nm at M1.5 at 60K (one way of course); a useful tool for sortie generation for long range missions off of remote airfields such as Guam.

I doubt that a bit. I think altitudes above 45000ft require afterburner to fly supersonic, at least that is what Stevenson writes. Maybe under favorable conditions it is possible, but it looks like the aircraft cannot supercruise at 50000ft pressure altitude, at least not from the limited data given.
My “assessment” shows that the 360nm + 100nm supercruise, both in and out, is possible, with a difference of 800lbs, which is nothing considering the crude methods. See that I have chosen optimum altitudes.
[ATTACH]163218[/ATTACH]
See that I have no burner reserve, while I do have normal reserves. 15% for take-off, climb and stuff is quite OK, while it means a military thrust climb of course.
The cruise and supercruise sections are quite fast, a cruise at M0.8 or .85 would yield better range. Guessed from the Stevenson graph you can see 6% better specific range at M0.8, leaving saving about 2000lbs of fuel on the subsonic cruise sections.
Not incorrect, but incomplete! Once you get around 65-70,000 feet, the temperature and the speed of sound INCREASE. They increase and decrease based on atmospheric temperatures all the way until you hit space. Saying that the speed of sound decreases because the temperature decreases is not correct, since eventually the speed of sound will increase again.

I am further an engineer, no physics nerd.
