Army-developed multimission launcher ‘off the table’
By: Jen Judson
WASHINGTON — The Army spent years internally developing its own multimission launcher for the Indirect Fires Protection Capability program — designed to counter threats like rockets, artillery and mortars as well as cruise missiles and unmanned aircraft systems. But that grand plan is now officially off the table.
The service has purchased two Rafael-made Iron Dome systems as an interim solution to get after the cruise missile defense capability gap, but it's taken a step back to rethink its enduring IFPC program strategy.
While much is up in the air, it's certain that the launcher that will ultimately be part of the IFPC program won't be the MML.
“It'll be something different that we will develop,” Brig. Gen. Brian Gibson, who is in charge of the Army's air-and-missile defense modernization, told Defense News at the Association of the U.S. Army's annual conference.
As of 2016, the Army had spent $119 million to build MML prototypes, which included owning the technical data rights. The cost of developing the system outside of the Army would have been about three times as much according to the service at the time.
Over the course of its development, the launcher was able to defeat a cruise missile target and an unmanned aircraft system using an AIM-9X missile at White Sands Missile Range, New Mexico, and fired the Miniature Hit-to-Kill (MHTK) and Tamir missiles as well.
The U.S. Army had awarded three $2.6 million contracts in the summer of 2018 for the first phase of a program to find a second interceptor — the Expanded Mission Area Missile (EMAM) — for the MML. Also already selected was the first interceptor for the launcher, the Sidewinder.
Lockheed Martin's MHTK missile and two missiles from Raytheon were chosen to be qualified for the launcher: Sky Hunter, the U.S. version of the Iron Dome missile Tamir; and the Accelerated Improved Interceptor Initiative missile.
The effort to qualify the MHTK has been paused, Scott Arnold, Lockheed Martin's vice president and deputy of integrated air-and-missile defense with the company's Missiles and Fire Control business, said at AUSA.
The company did not have an intercept test, but was able to move the MHTK missile through some testing prior to the Army's decision to pause the program.
The Army may take technologies developed as part of the MML effort and spiral them into a future launcher, “but there were a lot of things, with all the right reasons, that launcher turned out the way it did,” Gibson said. An assessment of the launcher determined it was not sufficient for an enduring capability, he added.
“All the variables of when you define a new piece of hardware matter and, for air defense, it really comes down to angles you launch things at, whether it's vertical or whether it's horizontal, and the applicability of how many different interceptors potentially you can put in,” Gibson said. “Those are all lessons learned from MML and it matters on the threat set.”
The one-star added that he is confident the Army is capable of developing something appropriate on the right timeline when it comes to a launcher for the enduring IFPC plan.
And while the service doesn't want to buy beyond the two batteries of Iron Dome already purchased, the Army is considering the feasibility of taking its launcher and missiles for the future IFPC program.
The Army has until the end of 2023 to field an initial enduring capability or, by law, will have to buy more interim Iron Dome systems.

Satellite Imagery + Social Media = A New Way to Spot Emerging Nuclear Threats
BY PATRICK TUCKER A research team is training computers to find and fuse clues from wildly different rivers of digital data. Hiding illicit nuclear programs might be getting harder, thanks to new ways of gleaning and combining clues from various rivers of digital data. That's the conclusion of new research funded in part by the U.S. Energy Department's National Nuclear Security Administration. Satellites offer one kind of information; social media another — particularly inside countries that may be trying to flout inspections. But large volumes of satellite imagery and social media data aren't similar. You can have one analyst examine satellite pictures and another look at social media posts to see if they align, but the process is time-consuming and generally far from comprehensive. The study's authors developed a method for fusing different types of data in a machine-readable way to offer a much clearer picture. “In light of their ubiquitous emergence, social media increasingly promise to be of great value even though associated applications have thus far remained simple, and their fusion with other data has been largely ad hoc,” the team from North Carolina State University writes in “Fusing Heterogeneous Data: A Case for Remote Sensing and Social Media.” Only by creating a new statistical method for fusing the outputs of satellite data and social media data do you get something you can use to predict what might happen next within a given area of interest, such as a specific nation's nuclear enrichment or weapons development. The researchers looked at satellite and social media data from August 2013, when deadly floods killed eight people and caused widespread damage in Colorado. They sought to show that if you could algorithmically identify which imagery showed the flooding from space, and which geotagged tweets described it on the ground, you could could much more quickly verify one data set against another — that is, you could determine whether incoming social media data supports the conclusions you might be reaching from your satellite data, and vice versa. “Next steps for the project include evaluating nuclear facilities in the West to identify common characteristics that may also be applicable to facilities in more isolated societies, such as North Korea,” notes a press release on the paper. One of the authors, NCSU computer and electrical engineering professor Hamid Krim, said the team would try to “address the insufficient knowledge in general in areas of great interest (e.g. N. Korea and Iran). The goal is to come up with systematic methodologies to transport knowledge about nuclear environments available in other areas (e.g., in the West) to these domains where there is very little available. Creating such an environment in these places of interest will help them detect potential undesired activity.” Of course, there are limitations to media monitoring in Iran and North Korea. The former's social media environment is largely underground, thanks to bans on Twitter and many other social networks. The latter has virtually no social media environment at all. Krim noted that the “adversarial strategy” of social-media censorship makes his team's analysis harder. But even social posts from nearby countries can help illuminate their more secretive neighbors, he said — think tweets from Japan after earth tremors are felt. https://www.defenseone.com/technology/2018/07/satellite-imagery-social-media-new-way-spot-emerging-nuclear-threats/150146/
