Well its high time US/NATO leave Afghanistan besides the material looses in terms of aircraft/choppers they are now getting human losses in friendly fire and its getting worse for them.

You cant reform stone age people no matter how hard you try ....Afghanistan for NATO gets worse every day

True but allowing them to continue is not smart either. The NA needs to be supported against taliban and pakis. Pakistan must be pushed into a perpetual state of civil war for there to be peace in the region.

Keeps them busy killing each other without turning on their neighbors. Balochistan, pukhtoons are already in a state of civil war. Sindhis and POk residents need a push.

The way they started this WoT , their tactics was flawed . Instead of crushing pakistan first , the sponsor and organiser of terrorism, they simply collaborated, seing what many say as near term stratgic compulsions, they over relied on pakistan assuming the fact that pakistan as a state would continue its existence even after they leave afpak . But long term calculations suggest that they will be in loss and their purpose of crushing cant be solved unless they finish what is known as the terrorist state of pakistan.
But , they still have a little window into this

F-35C's redesigned arresting hook design validated

Keep this issue in mind. We'll see how things go when the Naval LCA goes for tests aboard the newly designed ramp at INS Hansa.

After India Success, Is Dassault Rafale A Favorite In Brazil?
Wed, Sep 5, 2012 13:30 CET

Brazil has taken up India’s offer to review its notes on selecting a winner for the MMRCA (medium multi-role combat aircraft) competition, as the emerging South American nation looks to add 36 fighter aircraft to its Air Force.

While visiting New Delhi, Brazilian President Dilma Rousseff met with Indian officials on the sidelines of the BRICS conference to confer over India’s selection of the Rafale.......... <SNIP>

Defense Merger to Push Rival Deals?
September 14, 2012, 5:25 p.m. ET

By DANIEL MICHAELS and DAVID GAUTHIER-VILLARS

The proposed merger of Airbus parent European Aeronautic Defence & Space Co. EAD.FR +1.17% and Britain's BAE Systems BA.LN -0.44% PLC to create a global titan could prompt rivals to strike deals that they have long debated but failed to complete, say industry officials.

Smaller European rivals, in particular, have danced around each other for years, but differences over valuations and strategies have scuppered the talks. French aerospace and defense groups Thales SA HO.FR -0.47% and Safran SA, SAF.FR -0.21% for example, have acknowledged repeated talks that came to no resolution.

If EADS and BAE succeed in plans they revealed Wednesday to create the world's largest aerospace-and-defense company, rivals in Europe and the U.S. could feel pressured to grow, analysts said............<SNIP>

Air Force insiders foresaw F-22 woes

http://news.yahoo.com/ap-impact-air-for ... 52828.html

Years before F-22 pilots began getting dizzy in the cockpit, before one struggled to breathe as he tried to pull out of a fatal crash, before two more went on television to say the plane was so unsafe they refused to fly it, a small circle of U.S. Air Force experts knew something was wrong with the prized stealth fighter jet.

Coughing among pilots and fears that contaminants were leaking into their breathing apparatus led the experts to suspect flaws in the oxygen-supply system of the F-22 Raptor, especially in extreme high-altitude conditions in which the $190 million aircraft is without equal. They formed a working group a decade ago to deal with the problem, creating an informal but unique brain trust.

Internal documents and emails obtained by The Associated Press show they proposed a range of solutions by 2005, including adjustments to the flow of oxygen into pilot's masks. But that key recommendation was rejected by military officials reluctant to add costs to a program that was already well over budget.

Nope that didn't work out. Funnily enough it is Russia which is now backing this project. Those propfans are certainly something though.

China is now looking at the Y-20.

does the AN70 fit in our MTA bucket? just asking.

The aircraft has a 19.1 metre (22.4 metre with the ramp) x 4 metre x 4.1 metre cargo space and can carry 47 ton of cargo. Powered by four Progress D-27 propfan engines, each turning a pair of contra-rotating scimitar propellers

Not the MTA bracket. Another Antonov design (An-148 derivative) was talked about though as a starting point for the MTA and it would possibly have carried a few tonnes more than the Il-214 baseline.

MTA is a 18-20 tonne bird looking to take on the KC-390 ( if that ever happens).

In fact there is a possibility that the HS-748 replacement aka MRTA will see the Indian private sector tie up with the Ukrainians.

This An-70 may also be the subject of discussions. Because Roos needs a competitor to the A 400M.

An-178 is a good replacement for MTA , its in 15-18 T cargo weight class and the civil variant has already flown many thousand hours with passengers.

As far as Risk to Reward ratio goes its a much better choice over MTA or KC-390

The An-178 is a derivative of the An-148/158 stable and that is precisely the derivative which was discussed. But it has been passed over in favour of the Ilyushin design.

And "Rusaviation" is contradicting what has been circulated before when it says 15-18 tons. because the An-158T which is the cargo version was actually being billed for 25 tons and this is what is now going forward as the "An-178".

Russia to field Kh-101 cruise missile next year
Currently being flight-tested, the new weapon will enable bombers to hit targets with an accuracy of 10m (33ft) from a mission range of up to 5,400nm (10,000km) :shock: , giving Russia's Long Range Aviation command its first such precision-strike capability.

The subsonic Kh-101 navigates primarily by using Russia's GLONASS satellite navigation system, but also has a back-up inertial guidance system. It will also be to hit small moving targets :idea: , such as vehicles, the paper says.

If you have a range of 10000 km why do you need a bomber? That's the range of bomber + missile right?

Unless they want to invade antartica that range is useless. 10000 km range makes the bomber completely redundant especially for a country stretching across two continents.

Looks like it incorporates some Low Observable characteristics as well.

Apparently, Each Tu-95 can carry EIGHT of these! Just image the damage 2 bombers with 16 of these nuclear bad boys can do in an opening salvo!

Somehow I would have preferred a missile with 1/3rd the range (2000 miles) but being much faster (mach 7+). I really don't see the point of launching a slow moving missile at such an extreme range.

Doesn't look like a 10,000 km aircraft to me. Compare it to a Global Hawk which can fly from the US to Australia. Perhaps 1000 kms?

I thought these bad boys had 3000km range. Being relatively slow, fighters can chase and take out with aam..so no point firing them from too far away except against folks like libya or syria.

However if we want to strike infra targets in interior of dragon and tibet using glcm telars from eastern india...a 3000km glcm has a role.

Mostly we can manage with 750km range weapons even against deep sam units and radar networks for military role.

500 knots at 50 feet altitude is darn fast! Now you see it, now you don't.

I doubt they could carry those kind of payload for An-158T must be some erronous information floating , those kind of payload are generally carried by 737 plus kind of aircraft . An-178 was always 15-18 T payload

Yefim Gordon in his book Russian Air Power mentions that Kh-101 range is 5,500 km and Kh-55SM range at 3,000 km both missile carry 400 kg warhead the difference is Kh-101 is a clean slate design and Kh-55SM is derived from the nuclear Kh-555 which itself is a deeply modified Kh-55.

Even Kalbir-NK LACM has a range of 2600 km as officially confirmed by RuN

You need a bomber because you still need a carrier platform to afford flexibility on where these platforms can be moved ...you dont have to use the full 5500 km range you can always use say 2000 km range to target and use the remaining fuel to map out a stealthy lo-lo mission , which is trading range for stealthy trajectory.

Russian Air Force to Get New Cruise Missile in 2013

The Russian Air Force will accept into service in 2013 the new Raduga Kh-101 cruise missile, capable of delivering precision strikes with a conventional warhead at long-distance, an Air Force source told Izvestia on Wednesday.

The new missile, currently being flight-tested, will be able to hit targets with an accuracy of just 30 feet (10 meters) at ranges of up to 6,000 miles (10,000 km), giving Long-Range Aviation its first precision-strike long-range weapon, the paper says.

The Russian Air Force's bombers currently deploy the Kh-555 conventionally-armed cruise missile, which only has an accuracy of 75-90 feet (25-30 meters) accuracy.

The subsonic Kh-101 navigates primarily by using Russia's GLONASS satellite navigation system, but also has a backup intertial guidance mechanism which can take over if its SATNAV is jammed. It will also be capable of hitting small moving targets like vehicles, the paper said.

<snip>

It will be very useful for hitting targets from unexpected routes. The southern border of the US is lightly covered as compared to the northern border. Tu 160 is horrible at stealth so they would have to release from outside radar coverage to maximise its chance. The other alternative like a supersonic missile can easily be shot down by ABM systems. Subsonic stealth missiles do not get detected easily by ground based radars. They are also planning a new bomber PAK DA. The new missile could probably have a loiter time measured in several hours. This way they can leave the missile to loiter at its target for hours before hitting the target while the Tu 160/ Tu 95 is outside the danger zone.

There was a lot of scare in the media when a Russian Akula was found to be lurking in the Gulf of Mexico. I suppose the popular perception that it is America's soft underbelly is playing a key role. But this weapon or the Akula is not US centric. Any missile in sea skimming mode is going to shorten its range considerably. So a high range is probably a good place to start off. Diversions, loitering & terrain hugging modes will lower the range.

I think that Russia still sees US as its no 1 threat and weapons are designed accordingly. They probably figured out it is cheaper to build a stealth missile than to build a stealth bomber.

The Akula story was released by Bill Gertz formerly of the Washington Times now with the Washington Free Beacon, a house organ for the Center of American Freedom chaired by Michael Goldfarb, a propagandist for the Koch brothers who have more money than God and who firmly believe that billionaires should run the country through purchased politicians. They ae deeply concerned that President Obama is soft on defense and that US military cuts will weaken the nation.

http://www.businessinsider.com/everyone ... ico-2012-8

The US Navy will not confirm or deny the Akula story. The Russians will not confirm or deny the story. If you believe the story then enjoy.

Finally, the US DoD understands the Black Swan concept which was painfully brought to them by the 9-11 terrorist strike. In the terrorist strike on the Pentagon, the communications section that the brass depended upon to give orders to their far flung outposts was wiped out, except for the US Navy which had a section with its own global communications. For a number of days that is what they used which included an Aegis class warship parked off the US east coast, IIRC. I think that situation has since been corrected. The US DoD now understands the concept of "recovery" versus "resilience". Until the next Back Swan event.

Typical problems faced by startups and 787 remains worlds most advanced civilian aircraft flying today a military equivalent of F-22 if such a comparison is valid and higher the complexity of an aircraft more are the chances that it may end up facing some issue during start up , the domination of 787 will only be broken when A-350 takes to air.

IIRC even A-380 faced some issue typically late into its flight program.
