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.

By: Todd South A recent annual conference at the epicenter of the Army's maneuver force training saw combat arms leaders focusing on transforming the force with an eye toward future conflict. Though in past years portions of the annual conference have been open to the media, this year staff decided to close the entire event to outside media. The following information was gleaned from Army releases on the event. Gen. Stephen Townsend, commander of Army Training and Doctrine Command, told attendees that five near-term priorities will drive how well today's soldiers are ready for their next operating environment. Those priorities include: A review of how the Army recruits its soldiers and a plan to improve. Improving the leader-to-led ratio and resourcing in initial entry training. Successfully standing up Army Futures Command. Fielding a new Combat Fitness Test and changing the force's fitness culture. Ramping up Multi-Domain Operations into doctrine and practice. Each of these near-term priorities have some early work already completed, with more on the way.
