  MDA pauses defensive hypersonic missile design to refocus plan

  By: Jen Judson   WASHINGTON — The Missile Defense Agency has paused its effort to design a defensive hypersonic missile and wants to refocus its plan of attack by concentrating on near-term options that could feed into a more “elegant” solution, according to Vice Adm. Jon Hill, the organization's director. The agency tapped industry in January to design and build an interceptor capable of defending against regional hypersonic weapons threats, releasing a draft request for proposals to build prototypes. The request directed industry to submit whitepapers by March 19 to build a Hypersonic Defense Regional Glide Phase Weapons System interceptor. The plan then was to select at least one prime contractor to build prototypes that would culminate in a flight test, according to the draft RFP. But last month, the agency updated its posting on the federal government's contract opportunities website and said the final solicitation was under review. It also said the agency was assessing COVID-19 impacts, technology maturation efforts, threat analyses, and empirical data from the recent joint Defense Department hypersonic testing in March “to accurately establish the technical baseline and future end-state for hypersonic missile defense and the (RGPWS) effort.” Agency leaders said they expect to complete the review by the end of the first quarter of fiscal 2021. “One of the reasons we took the pause and said, ‘We'll get back to you later in the year,' is we want to see what we can do in the very near-term, and I'll define the near-term as the mid-20s, and then feed the science and technology investments going so you can get to that farther-term, more elegant solution,” Hill said at the virtual Space and Missile Defense Symposium Aug. 4. “But we want to get that capability out there as soon as possible to defend against the hypersonic threat and we want to continue to build out that capability and we believe the glide phase, further back in that trajectory, is always better than the terminal systems that we got today,” Hill added. He noted that the capability to take out threats in the terminal phase of flight is still critical. But, “you will want to move back that trajectory as far as you can,” he said. Achieving “glide phase” defensive capability could come through a variety of technologies, he said, including different warhead types, different effector types and what kind of propulsion is used to get there. MDA is on a long-term path to achieving hypersonic defensive capability, but it is focused first on its Hypersonic and Ballistic Tracking Space Sensor (HBTSS), according to Hill. “That is number one, we have got to be able to sense, detect and get tracking and fire control information down to the shooter,” he said. As the agency went through its analysis of alternatives for a defensive hypersonic interceptor, “we recognized there are two paths you can take to get to a weapon system,” Hill said. MDA is going to build off its command-and-control battle management and the effectors it has in place, Hill said, adding the agency can take advantage of terrestrial-based and mobile sea-based sensing today to get tracking data and push it where it needs to go. “The question is how long do you stay in the science and technology world? You should also take a look at a quick development path and that is what we are looking at now,” Hill said. https://www.defensenews.com/digital-show-dailies/smd/2020/08/04/mda-pauses-defensive-hypersonic-missile-design-effort-to-refocus-plan/

  NRL Pigment Package for Ships Slows Discoloration, Lowers Solar Temperature Load

  By Sara Francis, U.S. Naval Research Laboratory Public Affairs WASHINGTON (NNS) -- A pigment package designed by the U.S. Naval Research Laboratory (NRL) to slow discoloration of the exterior coating on surface ships has started to make its way into the fleet and is producing early, positive results. NRL researchers created the pigment combination to satisfy the fleet requirement for the Navy standard "haze gray" paint that will remain color stable for longer than current coatings. While many paint manufacturers had produced new coating technologies that solved a variety of other problems, such as corrosion and delamination, some ships still showed discoloration in as little as 18 months. Additionally, different coatings from different manufacturer's fade to different hues, resulting in an inconsistent appearance between the original coatings and any in-service touch-ups or repairs. “We had a good idea on how to solve the issue, and we leveled the playing field by providing the pigment combination to all companies at the same time,” said Dr. Erick Iezzi, senior research chemist in the Center for Corrosion Science and Engineering at NRL. NRL is currently working with Naval Sea Systems Command, Naval Systems Engineering Directorate, Ship Integrity & Performance Engineering (SEA 05P) to transition the new pigment combination into a military specification, which will become the standard for haze gray paint applied to surface ships. The first vessel to receive a coating with the pigment combination was USS Essex (LHD 2) in 2017. The most recent to vessel to receive it was USS George Washington (CVN 73). While all paint manufacturers have access to the pigment technology, three companies have already started mass-producing the paint, generating an estimated tens of thousands of gallons thus far. Recently, Sherwin-Williams won the Society for Protective Coatings Military Coatings Project Award of Excellence for its new topcoat paint that incorporates the new pigment after it was used to overhaul USS George Washington. “It was motivating to know that several companies were willing to lean on our expertise to provide a new technology that would produce the best product for the Navy,” Iezzi said. From 2012 to 2013, Iezzi worked with corrosion science researchers Jimmy Tagert and Candice Langaster to design five new pigment combinations and test them for color stability, solar reflectance and other coating properties. After testing all combinations, they provided the best performer to paint and coating manufacturers to begin integration in 2015. The pigment combinations underwent testing at NRL's Key West facility for atmospheric exposure performance and accelerated weathering. Coatings that contained the new pigments proved to have excellent color stability, were five times harder than silicone alkyd, had improved gloss retention and chemical resistance, and provided greater barrier properties. “It was great working with the manufacturers and demonstrating our ability to provide a product needed for the fleet,” Tagert said.
