Zitat:ISRAEL SEES RIVALS IN WESTERN-BASED AIR FORCES


TEL AVIV [MENL] -- The Israel Air Force has determined emerging threats from neighboring Arab states that have been building combat air fleets based on U.S. aircraft.

Zitat:Israel launches new spy satellite

“This will significantly boost our intelligence-gathering capabilities,” a defense official said.

The Ofek 9 weighs about 300 kg. and can complete an orbit every 90 minutes.

While the new satellite will not represent a significant technological breakthrough – it will carry the same camera as the Ofek 7 – it will provide the IDF with greater flexibility in utilizing its space assets.

The last satellite, the TecSar, was launched by Israel from India in 2008. Also developed by IAI, the TecSar can create high-resolution images using advanced radar technology called Synthetic Aperture Radar, enabling it to produce images in all weather conditions and even at night.

Israel also operates the Ofek 5 and receives services from the EROS B.

After the Ofek 9, the next spy satellite launched into space will be called the Opsat 3000, scheduled to be sent into space later this decade and to be capable of unprecedented optical remote sensing at extremely high resolution.

Zitat:Israel debates F-15 purchase

Silent Eagle aircraft debuts in US; Defense Ministry follows closely.

The Israel Air Force closely followed the maiden flight of the F-15 Silent Eagle, which took to the skies over the weekend in the US. Debate continued within the Defense Ministry over whether it should buy the aircraft in the face of expected additional delays in the development of the F-35 Joint Strike Fighter.

While Boeing is still reportedly awaiting Pentagon approval to export the plane, Israel has already held a number of initial discussions regarding the plane and its capabilities.

The maiden flight comes as the Defense Ministry is holding a series of consultations aimed at reaching a decision on which aircraft to buy and how many by the end of the summer.

Israel would like to buy the JSF fifthgeneration fighter jet manufactured by Lockheed Martin, but is concerned with expected delays and the soaring price of the plane, now estimated at close to $150 million. In comparison, the F-15SE will reportedly cost around $100m.

Zitat:Israel's secret new weapon?

Israeli company uses nanotechnology to develop paint that makes planes disappear off radar

Imagine for a moment what the battlefield will look like in the future. Unmanned planes flying through the air; robots fighting on the ground; smart missiles hunting down targets. Now imagine that none of this can be detected on radar screens.

It may sound fictional, but it's happening. An Israeli company called Nanoflight is currently developing a special paint that makes drones, missiles, or war craft simply disappear. Or, to be more precise, they become very difficult to detect.

The critical stage in developing the paint, which was developed in a nanotechnology lab, has recently concluded, and a successful test run was conducted this week. For the test run, a thin layer of the material was painted on dummy missiles, and radar waves aimed at them had a difficult time registering them.
The paint particles don't make the missile's detection on the radar disappear completely, but make it exceedingly difficult to positively identify the object as a missile. In the future, this development will allow any missile or jet significantly decreased radar detection.

Even though they may not entirely disappear from radar screens, this technology is a considerably more cost-effective method to evade radar detection than purchasing an American stealth plane for $5 billion.

How does it work? In order to locate objects, the radar transmitter sends out electromagnetic waves. When these waves hit an object, they are scattered in all directions, with some of them being bounced back to the radar itself. Regular signal reception indicates the existence of an object.



The nanotechnology developed envelopes the object, absorbs the radio waves emitted by the radar, and releases them as heat energy scattered in space. In doing so, the material disguises the object, making it difficult to identify by radar.

"We are only at the beginning and are discovering new worlds everyday," said Eli Shaldag, a former senior Israel Air Force official who worked on the Arrow missile project. He currently is part of the military applications department of Nanoflight.

"This is a breakthrough with the potential to change the rules of the game in the battlefield," Shaldag said.


When will the material be ready for use on war craft?

"We have already completed the main development stage. We conducted a number of tests and discovered that the particles in their nanotechnology composition do significantly neutralize the ability to detect objects that have been painted with the material. We are entering the second stage, after which we will already be able to produce the material in larger quantities."

Will this material be applicable for additional uses in the future?

"Absolutely yes. Discovery of nanotechnology materials is still in its infancy, and we are decoding the secret of this technology's power every day. We are currently working on developing an application of the material that will work with infrared so that soldiers won't be detected on night-vision goggles."

According to company officials, the material can also be used for civilian purposes.

"Just like the nanotechnology material can prevent a radar from detecting a missile, it can also prevent radiation emitted by electrical transformers from reaching nursery schools," said Nanoflight CEO Ricardo Burstein.

Burstein also noted that the material can prevent pollution through its absorption and transformation properties.

"In the future, it could be painted on sidewalks and roads in order to decrease air pollution. We are currently conducting an experiment with the City of Ramat Gan in which we are painting guardrails with the material in order to purify pollution from cars," Burstein explained.

NANO COMPOSITES – A CONTROVERSIAL CASE STUDY
...
High conductivity nanocomposites have been developed by research people now. The scientist from Iran and Azerbaijani were under this. TEHRAN (INIC)- The Iranian Researchers in cooperation with their colleagues from Azerbaijan Republic, managed to synthesize highly conductive nanocomposites broadly used in the production of toxic gases' sensors and radar wave absorbing coatings. Mohammad Reza Saboktakin, an Iranian researcher synthesised nanocomposites by a specified chemical method with good efficiency. The advantage of the developed material was said that it has the ability of absorbing electromagnetic waves of different frequencies by metallic nanoparticles.
...
Polyaniline, polythiophene, polypyrrole, similar heterocycles and common polymers, which can be used for making conductive nanocomposites, are of most importance in this research.
Saboktakin stressed that the product has applications in the production of toxic gases' sensors in petroleum, gas, and petrochemical industries, the production of wave absorbing coatings especially radar wave ones and the production of conductive coatings etc.

Zitat:Production of Anti-Electromagnetic Textures in Iran
2008-08-02
Using iron nanoparticles, Iranian researchers have managed to produce a conductive texture, which is able to damp the electromagnetic waves.
...
These textures not only “can be used in safety clothes which are used in some particular industries”, but also may be employed as “anti-radar covers”.
Furthermore, these textures may be used to enhance the safety in various workrooms, radar stations and radiography centers. Also it may give help to computer operators.
