  The data challenge of space-based hypersonics defense

  By: Nathan Strout Managing data is the biggest challenge to developing a new space-based sensor layer that would help detect hypersonic weapons, the director of the Missile Defense Agency said Oct. 7. The agency is working toward building the Hypersonic and Ballistic Tracking Space Sensor, a layer of sensors on orbit that would be capable of detecting and tracking hypersonic weapons that the nation's current missile defense architecture was not designed to handle. The new system will be built into the Space Development Agency's constellation of low earth orbit satellites. For Vice Adm. Jon Hill, the director of the agency, designing the sensors for the system is a surmountable engineering issue and evolving commercial launch capabilities mean it will be easy to get the technology to space once its ready. The real challenge is “the passing of track data between different space vehicles and maintaining track and dealing with clutter.” Hypersonic weapons are dimmer than traditional ballistic missiles, making them harder to detect. The sensors will have to be able to remove that clutter, detect the threat and then pass their data to the next LEO sensor, which will pick up the object as it travels around the globe at hypersonic speed. Allowing for that data flow from sensor to sensor is essential to the effective operation of the system. Hill compared the complexity of that data transfer to his time in the Navy, where information had to go between moving vessels, but the data issue with satellites is magnitudes of order more difficult. “When you put yourself on a moving body that's moving, not at 30 knots but at a much higher speed, you know, maintaining the stability of that track, being able to pull the clutter out of it, determining how much you want to process up on orbit versus how much you want to feed down and process on the ground, then how you distribute. Do you distribute directly from the sensor? Do you control the weapon from space? Or do you take it to the ground station and do it there? There [are] different trades, and we'll probably do it differently in a lot of different ways because that adds to the overall resilience of the system,” Hill said speaking at a Center for Strategic and International Studies event October 7. Finding the right answers to those questions will be a priority for the MDA as it works to works to get the system on orbit quickly. “It's going to be a great capability. We just need to get it up there as soon as we can and rapidly proliferate,” Hill said. https://www.c4isrnet.com/battlefield-tech/space/2019/10/09/the-data-challenge-of-space-based-hypersonics-defense/

  Boeing Is Refurbishing Harpoon Missiles for U.S. Navy Submarines

  Posted on February 9, 2021 by Richard R. Burgess, Senior Editor ARLINGTON, Va. — Boeing has begun work to return the Harpoon cruise missile to operational status in the U.S. Navy's submarine force after a more than 20-year absence. Boeing received an $10.9 million Naval Sea Systems Command contract late last month to refurbish 16 Harpoon missile capsules and four all-up rounds of encapsulated Block 1C Harpoon missiles for the Navy's submarines. Work is scheduled for completion by December 2022. The UGM-84A Harpoon Block 1C missiles will be integrated on the Navy's Los Angeles-class submarines. The UGM-84A is encapsulated to be fired from a torpedo tube and has a rocket booster to propel it above the surface of the water and into flight. “I am happy to report that we will have the first refurbished [Harpoon] missiles delivered to the fleet in [fiscal] ‘21,” said Rear Adm. Thomas Ishee, director of undersea warfare in the Office of the Chief of Naval Operations, speaking Nov. 7 at the Naval Submarine League's annual symposium in Arlington. In a demonstration in the 2018 Rim of the Pacific exercise, a Harpoon was fired from the Los Angeles-class attack submarine USS Olympia at a target ship, the first time one was fired from a U.S. Navy submarine since the UGM-84A Harpoons were withdrawn from the force in 1997. The UGM-84A is encapsulated to be fired from a torpedo tube and has a rocket booster to propel it above the surface of the water and into flight. “The Navy has a deep inventory of Harpoon Block IC missiles,” said Sally Seibert, director, Cruise Missile Systems at Boeing, in a statement. “These missiles can be refurbished and reintegrated into the fleet in a shorter timeframe, and at a fraction of the cost, compared to purchasing new missiles — and that is exactly what our team is doing.” The Harpoon cruise missile is a combat-proven, all-domain anti-ship missile used by the Navy and more than 30 international customers, a statement from Boeing said. “Evolving over the years to keep pace with emerging threats, the Harpoon Block II includes a GPS-aided guidance system that allows for autonomous, all-weather capability — and can execute both anti-ship and land-strike missions. The more advanced Harpoon Block II+ adds a data link that allows for in-flight targeting updates.” “The shelf life of the Harpoon missile allows us to maximize existing capability by bringing this weapon back to the submarine fleet,” Seibert said. “Customers who currently have Harpoon missiles in their inventory are prime candidates for refurbishments, or even upgrades, to add this extremely viable and cost-effective weapon to their arsenal.” Currently, more than 600 ships, 180 submarines, 12 different types of aircraft and several land-based launch vehicles across the world are integrated with Harpoon missiles, Boeing said. https://seapowermagazine.org/boeing-is-refurbishing-harpoon-missiles-for-u-s-navy-submarines/
