MDA to deliver mission-critical SAR information for maritime surveillance
ichmond, BC - MDA, a Maxar Technologies company (formerly MacDonald, Dettwiler and Associates Ltd.), (NYSE: MAXR) (TSX: MAXR), today announced that it has signed a multi-million dollar contract with the South African National Space Agency (SANSA) for a one-year maritime surveillance program that includes the delivery of synthetic aperture radar (SAR) data products from the RADARSAT-2 satellite, using MDA's global network of ground receiving stations. The contract includes two additional option years.
As part of the Presidential program Operation Phakisa, SANSA has been tasked to acquire SAR imagery with the aim of enhancing the monitoring and protection of South Africa's coastal regions and oceans. Initiatives under this program are considered crucial in accelerating the delivery of South Africa's development priorities. Operations Phakisa estimates that the approximate total contribution of coastal resources (marine fishing, port and harbour development, attractive lifestyles, recreation and tourism) is 35% of South Africa's GDP. The information provided by the SAR data contributes to ensuring improved governance and enables the securing of South African resources, such as the National Ocean and Coastal Information System.
The South African Exclusive Economic Zone (EEZ) is roughly 1.5 million square km and forms part of the economic resources and trade routes of South Africa. The Council for Scientific and Industrial Research (CSIR), South Africa's central and premier scientific research and development organization will create the ship and oil detection products for SANSA to share with various government agencies.
“RADARSAT-2 provides a unique method of cost-effectively and accurately monitoring very large areas and providing information in near real-time, demonstrating immediate value to users,” said Mike Greenley, group president of MDA. “MDA has decades of remote sensing expertise to help our customers anticipate and address their most complex mission-critical challenges with confidence.”
Under this contract, using RADARSAT-2 information, MDA will provide systematic weekly broad-area surveillance over South Africa's EEZ and on-demand high-resolution image acquisitions. RADARSAT-2 Ocean Surveillance Mode is well suited for broad area maritime surveillance, and is unique as a single scene covers over 250,000 ㎢ and allows for the detection of ships and oil within the coastal and offshore regions regardless of light or weather condition.

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.
