  Israel Plans Anti-Missile Nano Satellite Constellation

  By ARIE EGOZI TEL AVIV: Israel is planning constellations of nano satellites, built by Israel Aerospace Industries (IAI), that will allow almost continuous coverage of “areas of interest,” which are likely to include Iran, Syria, Lebanon and other countries, according to experts that are not connected in any way to the program. IAI refused to comment. The first nano satellite was developed by IAI and was launched into space in 2017 as part of a scientific experiment. The 5-kilogram satellite — approximately the size of a milk carton — is equipped with special cameras able to identify various climatic phenomena, and a monitoring system that allows the choice of areas to be imaged and researched. ”We are developing the capability to launch a constellation of Nano satellites. The large number of satellites will give us the capability for a much higher rate of revisits, and actually a continuous monitoring of areas of interest.” says Opher Doron, general manager of IAI's Space Division. The nano satellites optical payloads are smaller and the quality of their optical payloads is lower. ”But by using a temporal resolution method this problem is dealt with in a very effective way,” Doron claims. “This method is not directly related to the quality of the sensor but is based on the frequency of revisits over a site.“ The other problem with smaller satellites is color. “Resolution is, of course, very important but we also work on improving the color quality of the images, Doron said. “A good intelligence expert does not need color to extract, the needed intelligence from a satellite image, but when it comes to decision-makers, color is of great importance.” What underpins all this? It takes a ballistic missile 12 to 15 minutes to travel from Iran to Israel. The earlier a launch is detected and the earlier the trajectory of the missile can be plotted, the better the chances to intercept it far from its designated target. Today, low orbit Ofeq spy satellites visit “areas of interest” in wide intervals so their optical or radar payloads cannot keep a persistent watch. When it comes to the ballistic missile threat, this is a major problem. Israeli sources say that some 30 minutes are needed from the command to prepare a ballistic missile for launch until it is ready for launch, and this if the protection silos are well equipped. If the enemy is aware of the “visiting” time of the spy satellites over his territory this can be the perfect time to avoid detection of the preparations until the launch itself. Once launch occurs, Israel is supposed to get warnings from Lockheed Martin's Space-Based Infrared System (SBIRS),the US constellation of geosynchronous earth orbit (GEO) satellites. The U.S also deploys an X-band radar system in southern Israel to improve detection of ballistic missiles. This complements the layer supplied by the Green Pine radar, part of the Israeli Arrow missile interceptors. The first nano satellite was launched from India on the PSLV-C37 launcher with 103 other nano satellites. The plan to build and launch nano satellites first emerged a decade ago. A joint company of IAI and Rafael would undertake the mission. But that plan was deserted. Yizhak Ben Israel, chairman of the Israeli space agency, served in the Israeli air force and later was in charge of developing Israel's most advanced and classified military systems at the development directorate in the Defense Ministry. He notes that, although nanosats possess much less exquisite capabilities than SBIRS or other large satellites, “when you use a constellation of such satellites the combined capability can be very effective in missions like locating missile launchers.” The other advantage of nano satellites is their price: “You go from hundreds of million of dollars for a full size imaging satellite to some millions of dollars when it comes to a nano satellite.” Not directly related to the nano satellite program but part of Israel's space effort, IAI teamed with British start-up company Effective Space to make a fleet of special satellites weighing roughly 880 pounds that can refuel other satellites in space. IAI signed an agreement for technological and financial cooperation with the smaller company. While Effective Space is headquartered in London, its CEO, Arie Halsband, was general manager of IAI's space division before starting his own company. https://breakingdefense.com/2018/10/israel-plans-anti-missile-nano-satellite-constellation

  3 ways America can fix its vulnerability to cruise missiles

  By: Bradley Bowman and Andrew Gabel September's drone and cruise missile attack on a major Saudi energy facility highlights the challenges associated with cruise missile defense. Americans might be tempted to dismiss this attack merely as evidence of a Saudi vulnerability, with little relevance to the U.S. homeland. However, given that an American-built air defense system failed to stop the attack, this would be a mistake. As China and Russia continue to develop and deploy advanced cruise missiles to threaten the United States, urgent action is required. In recent years, the Pentagon has focused on protecting the homeland from ballistic missile attacks by building a ballistic missile defense system consisting of radars and interceptors. This system can provide some protection against a limited ballistic missile attack on the United States, but it is not designed to protect American cities from cruise missile attacks. Unlike ballistic missiles, which arc high into the atmosphere and beyond before striking their target, cruise missiles fly at low altitudes, where ground-based radars struggle to detect them. And to defeat a cruise missile, the Department of Defense must first be able to detect and track it. America's adversaries “currently hold our citizens and national interests at risk,” the commander of Northern Command, Gen. Terrence O'Shaughnessy, testified before the Senate in April. “The homeland is not a sanctuary. For that reason, improving our ability to detect and defeat cruise missile attacks is among my highest priorities.” It is not difficult to understand why. Seeing this long-standing vulnerability, America's great power adversaries have worked to improve their cruise missile capabilities. Today, for example, Russia possesses a submarine-launched cruise missile that Moscow could use to circumvent existing U.S. missile defenses and target key East Coast military bases and population centers. And the cruise missile capabilities of U.S. adversaries are only growing more formidable. In April testimony before the Senate, Under Secretary of Defense for Policy John Rood warned that potential adversaries are developing sophisticated “cruise missile systems with increased speed, range, accuracy and lethality.” For its part, Russia is developing hypersonic cruise missiles. Russian President Vladimir Putin claims one of these cruise missiles could fly as fast as nine times the speed of sound. The Kremlin is also pursuing nuclear-powered cruise missiles with virtually unlimited range. Not to be outdone, China is developing its own hypersonic cruise missiles, supplementing its existing cruise missile stocks. Against both Moscow and Beijing's cruise missile arsenals, America's current defenses are inadequate. So what's to be done? The first step is for the Department of Defense to quickly assign a lead in the Pentagon for homeland cruise missile defense, which would enable key decisions related to the homeland cruise missile defense architecture — including decisions related to sensors and shooters, as well as command and control, battle management, and communications. This would help expedite efforts to integrate ballistic missile defense and cruise missile defense. Second, Congress should support efforts to deploy without delay the space-based sensors necessary to detect, track and ultimately defeat advanced cruise missiles and other missile threats to our homeland. Third, the Department of Defense should proactively look to partner with its impressive array of allies and partners to field — both at home and abroad — advanced cruise missile defense capabilities without delay. Consider the United Kingdom, Canada, Australia and New Zealand. These allies are already part of a long-standing intelligence sharing arrangement with the United States, known as the “Five Eyes agreement.” As Atlantic Council Senior Fellow William Greenwalt has suggested, systematically expanding this arrangement to institutionalize the shared development of military technology makes sense. Cruise missile defense might be one of several good places to start. Israel represents another obvious partner, as it possesses a proven track record on missile defense innovation, deep real-world experience, an admirable sense of urgency and a long history of cooperation with the U.S. on missile defense. Indeed, Israel and the U.S. have worked together for years to develop the Arrow and David's Sling missile defense systems. If we combine these international partnerships with the innovation prowess of the American private sector — as well as timely, predictable and sufficient funding from Congress — much can be done to address areas of shared vulnerability. That includes cruise missile defenses for both the American homeland and forward-deployed U.S. troops. The September attack on the Saudi energy facility may seem of little concern to most Americans, but that attack should serve as a warning regarding the unique challenges associated with cruise missile defense. If Iran could pull off such an attack, imagine what Moscow and Beijing may be able to do. If our great power adversaries believe a surprise cruise missile attack against the U.S. homeland or American positions abroad might succeed, it increases the chances that Beijing or Moscow would undertake such an attack. The Pentagon assessed in its Missile Defense Review earlier this year that advanced cruise missile threats to the homeland “are on the horizon.” The attack last month in Saudi Arabia suggests that horizon might be closer than Americans think. Bradley Bowman is the senior director for the Center on Military and Political Power with the Foundation for Defense of Democracies, where Andrew Gabel is a research analyst. https://www.defensenews.com/opinion/commentary/2019/10/29/3-ways-america-can-fix-its-vulnerability-to-cruise-missiles/
