    Expand missile defenses during the pandemic, don’t cut them

    By: Rebeccah L. Heinrichs Rogue states are taking advantage of the American preoccupation with the COVID-19 pandemic. North Korea may test another long-range missile according to the head of U.S. Northern Command, Gen. Terrence O'Shaughnessy. He warned Congress in March that the North Korean regime is still a serious threat and is improving its missile program. And last week, Iran's Revolutionary Guard successfully launched a satellite into space. This was the first for the terrorist paramilitary group, though not the first for the regime. The pandemic is likely to prompt Congress to reassess, cut and redirect spending, but safeguarding the American people from missile attack is an essential service the government cannot afford to scale back. Deputy Assistant Secretary of Defense Rob Soofer said at a recent Hudson Institute event: “[T]oday we are in an advantageous position vis-a-vis North Korea. Forty-four ground-based interceptors. Gen. O'Shaughnessy has complete confidence that the system will work and we can address the threat. Then the question is: Can we wait until 2028?” The Trump administration intends to deploy in 2028 the Next Generation Interceptor, or NGI, meant to handle far more complicated missile threats than what the Ground-based Midcourse Defense, or GMD, system was initially designed to do. Still, as Dr. Soofer explained, threats develop at an unpredictable pace, and so the Pentagon is pushing for initiatives to bolster defense in the meantime. Those initiatives will require serious bipartisan cooperation while concurrently developing the NGI and pursuing other advanced capabilities meant to dramatically increase the ability of the missile defense architecture. It's a tall order, but critical, nonetheless. First, and to be clear, the Pentagon has not yet embraced this step due to its determination to focus on NGI. But Congress should invest in more than just sustaining the current GMD system; it should improve it by adding 20 GBIs to the already fielded 44. The silos will be prepared for the additional numbers since, in 2017, President Donald Trump called for adding more deployed GBIs considering the heightened North Korea missile threat. The Pentagon began work on preparing for their delivery but never emplaced GBIs into those silos because Pentagon officials canceled the Redesigned Kill Vehicle. The Pentagon had anticipated the Redesigned Kill Vehicle for the nation's new GBIs. After evaluating the resources and time it would take to restart the production line of the Capability Enhancement II interceptors or to rapidly develop an improved kill vehicle that leverages new technology, the Pentagon should choose the most cost-effective solution. Recall, the Capability Enhancement II was the kill vehicle that performed well in the last complex flight test, which was the first salvo engagement of a threat-representative intercontinental ballistic missile target by GBIs. Regardless of the option the Pentagon would choose, the result would be a near-term enhanced capability by either increased capacity at a minimum, or an increased capacity with improved kill vehicles on 20 of the 64 at best. Either would be a much better scenario than keeping the backbone of homeland defenses stagnant while we anticipate the NGI in 2028. But that is not all the country should do. It should also move forward with steps the Pentagon has embraced. Those steps include improving the discrimination radar capability in the next few years so GMD can better detect and characterize the evolving threat, and deploying other existing systems to bolster GMD. Utilizing current systems with impressive testing records against missiles shorter than ICBM range as part of a layered homeland defense is called the “underlay.” As a key component of the underlay, Congress has directed the Pentagon to test the Aegis SM-3 IIA interceptor against an ICBM target. Unfortunately, because of the pandemic, the Missile Defense Agency's planned flight tests will be delayed, including for the SM-3 IIA. The threats facing the country will not wait for the end of the pandemic, and the Pentagon should reconsider that delay. As soon as the country can test the system, and if it is a success, it would be wise to prepare to deploy Aegis SM-3 IIA as the threat requires. If there is an ICBM attack against the U.S. homeland, a GBI would have the first shot at the incoming missile while it's in its midcourse phase of flight; and if an enemy missile gets through, and the Aegis SM-3 IIA is positioned correctly, it could have another shot at the missile as it begins its descent. There has been some concern about whether Russia or China have legitimate claims that bolstering homeland defense in this way is destabilizing. But no evidence supports these claims, and, as Dr. Jim Miller, an Obama-era undersecretary of defense for policy, said at a recent Hudson event: “We cannot and must not give Russia or China a veto over the United States' ability to defend ourselves from North Korea and Iran. That is an absolute no-go for any administration.” Another system that is a natural candidate for the underlay is the Terminal High Altitude Area Defense air defense system. Embracing that concept as well, Dr. Miller said: “It makes sense for certain contexts. And if you're looking at a shorter-range missile and a relatively small footprint of coverage, THAAD has a real chance to contribute in that. To me, that's certainly the case for Guam and Hawaii.” But what about cost? That's the $10 billion question — a question that happens to be valued at more than the current president's budget requires for the Missile Defense Agency. The budget request that Congress is currently considering for the MDA is roughly $9.2 billion, noticeably less than previous years, even as the role of missile defense is supposed to be expanding in the country's National Security Strategy. There is no margin for cutting the budget. Congress should rally around this mission and budget, and it should increase funding to sufficiently make these necessary improvements in the near term without paying for them by sacrificing investments like NGI for the not-so-distant future. It can do that without tipping the scale much more than $10 billion this year. That is eminently reasonable given the pressure every government department will feel after the sudden spending splurge due to the COVID-19 pandemic. Rebeccah L.

    Ready, Fire, Aim: PACAF Chief Emphasizes Hypersonics

    Steve Trimble As the U.S. Defense Department accelerates hypersonic weapons fielding, the air force's top commander in the Pacific region emphasizes that the missile isn't the only technology required to realize an operational capability to strike targets at speeds faster than Mach 5. The air force plans to achieve an early operational capability in fiscal 2022 with the Lockheed Martin AGM-183A Air-launched Rapid Response Weapon, a maneuvering boost glide missile fired from the wing of an aircraft, such as a Boeing B-52. Such weapons are capable of hitting targets at ranges over 1,000 km within 10 min., but similarly new advances in intelligence-gathering and command and control infrastructure are required in order to make full use of them, said Gen. Charles Brown, commander of Pacific Air Forces. “In the time of flight, eight to 10 minutes, I've got to have pretty good intel that the target is still going to be there, particularly if it's a mobile target,” Brown said. “Those are things I'm thinking about. It's nice to have this weapon, but I've got to have the whole thing.” The Defense Department also is working on other long-range-missile technologies. In August, Russia and the U.S. governments withdrew from the 32-year-old Intermediate-Range Nuclear Forces Treaty, allowing both countries to follow China's lead in fielding ground-launched ballistic and cruise missiles with a range of between 500 km and 5,000 km. Since August, the DOD has demonstrated a rudimentary ground-launched cruise missile and ballistic missile in flight, but a fielding decision is still pending a policy decision by the Office of the Secretary of Defense (OSD). Brown could offer no update on the status of the policy decision. “That may be a logical conclusion, but I'd refer you to OSD on where their approach is and where the department might land as far as where we're going in the future,” Brown said. https://aviationweek.com/shownews/singapore-airshow/ready-fire-aim-pacaf-chief-emphasizes-hypersonics

  • The Army is looking to make a sports bra that also measures soldier performance

    The Army is looking to make a sports bra that also measures soldier performance

    By: Meghann Myers The Army has issued uniform items from top to bottom and inside out, except for one very important piece of clothing: a bra. Turns out, the service once took a stab at creating a tactical women's undergarment, but abandoned the idea because it didn't suit a variety of shapes and sizes. A designer at the Natick Soldier Research, Development and Engineering Center has taken up the cause again — however, this time adding an element of performance measurement. “So, I thought, let's kill two birds with one stone. Let's give them something that fits well and also create a platform where we can run the same tests and analysis that previously had been done on the male majority,” Ashley Cushon said in an Oct. 25 Army release. She dubbed the project BAMBI ― Biometric Algorithm Monitoring Brassiere Integration. And no, the acronym didn't come before the name. “Although BAMBI is still in its very early research stages, I wanted an innovative name that alluded to the end goal of the item ― which is to function as an integrated platform for physiological sensing specifically designed to the female soldier's biology,” Cushon told Army Times in a statement. “Most importantly, I wanted it to be an acronym that was functional and distinctive, yet relatively feminine and impactful.” While testing the prototype, soldiers will be hooked up to a Holter monitor to measure Heat Strain Index, heart rate and core temperature to predict heat stroke, exhaustion and fatigue, according to the release. NSRDEC has done these tests before, Cushon said, but could only do them on men because of the design of the vest that houses the sensors. “There are certain fit parameters that weren't accounted for when it came to the final test item and its ability to be unisex,” Cushon said. “Due to the lack of industry items that are properly suited to meet the sizing requirements of the female soldier population, we were unable to collect female data during those particular tests.” Her team will use measurements and 3-D scans taken from thousands of soldiers during 2012′s Army Anthropometry Survey to create a sports bra with proper sizing. It's not difficult to create a sensor-mounting garment, but it is a lot of work to make sure it can be worn by enough soldiers to collect significant data. “Developing a female undergarment is no simple task,” Cushon said in the release. “There's too large of a variety of body shapes and sizes to meet every need. Currently, there is no industry solution that accommodates the sizing needs of our female soldiers.” And so, few women have been able to participate in NSRDEC's push to get sensors on soldiers. “Currently, if soldiers are wearing physiological monitors in the field, they're either wearing wrist-mounted devices or some variation of a chest strap,” Cushon said. “Of the two, the chest strap is the most accurate but can cause chaffing or is otherwise not very compatible with the rest of their gear.” Using an algorithm, Natick researchers can take heart rate and core temperature data to calculate heat stress on the body, which can lead to casualties. “The long-term goal is for us to create an effective female-centric platform for introducing integrated sensing technology into the Army's effort of improving soldier and squad performance,” Cushon. Aside from health data, the Army is using sensors all over, from measuring parachute jumps to creating situational awareness for the Bradley Fighting Vehicle. A woman-specific garment increases the likelihood that women can contribute to and benefit from research with wearable sensors. “Female soldiers are making invaluable contributions to our great nation, and they deserve clothing and equipment designed with them in mind,” Cushon said. https://www.armytimes.com/news/your-army/2018/11/06/the-army-is-looking-to-make-a-sports-bra-that-also-measures-soldier-performance
