Lockheed Aims For Laser On Fighter By 2025

How do you keep a laser focused on a target moving at hundreds of miles per hour? The answer is crucial to Lockheed lasers being fitted on Army trucks and Air Force fighters over the next few years.

WASHINGTON: “Lockheed Martin is working to fly a laser on tactical fighters within the next five years,” Lockheed laser expert Mark Stephen told reporters yesterday afternoon. “We're spending a lot of time to get the beam director right.”

That beam director, which keeps the laser beam on target, is a crucial but easily overlooked component of future laser weapons.

The Air Force Research Lab's SHiELD program aims to put defensive laser pod on fighters to defend them against incoming anti-aircraft missiles. An offensive laser to shoot down enemy aircraft would have to hit harder and at longer distances, so it's a more distant goal: Such weapons are envisioned for a future “sixth generation” fighter — like the NGAD prototype now in flight test — to follow the 5th-gen F-35, while the SHiELD pod will go on non-stealthy 4th gen aircraft like the F-16, as in this Lockheed video.

But the company's new beam-director design is actually getting its first workout on an Army system, the truck-mounted IFPC Energy Laser, which will defend against artillery rockets, drones, and, potentially, subsonic cruise missiles.

    Turkish Drones Destroy Russian-Made Air Defense Systems

    On Friday, a missile fired by a Turkish drone destroyed a Russian-made Pantsir-S1 deployed by the Syrian Army in Idlib province. This video released by Turkish media, shows an active Syrian Pantsir being destroyed by a Turkish drone. According to Turkish media, the Pantsir radar was active when it was hit, indicating that the system failed to detect the incoming missile. The Syrian Air Defense Force reportedly has more than 30 $14 million Pantsir S1 (SA-22) air defense systems. Russia has also strengthened its Syrian Khmeimim air base with Pantsir systems to prevent air strikes. The systems were deployed in Khmeimim after a series of drone attacks in 2018. Combat unmanned aerial vehicles used by the Turkish military against the Syrian army led to Syria's largest losses, according to the Turkish Ministry of Defense. After Turkey started using drones against the Syrian Armed Forces, Assad's army has lost about a hundred units of armoured vehicles and several hundred military personnel. Russian news outlet Avia.pro writes that, for unknown reasons, Turkish drones are invisible to Syrian air defense systems. According to the news outlet, Pantsir radars are possibly “blinded” by Turkish electronic warfare systems. Reportedly, Turkey has been using it Koral jamming system built by Aselsan, to degrade the effectiveness of Syrian air defense radars. The Koral, which has a range of 124 miles, has support sensors designed to detect and classify other systems in the area, and an electronic attack element designed to jam, deceive and overload enemy sensors The Turkish drones are reportedly using MAM-C and MAM-L ‘micro-munitions'—70- and 160-millimeter rockets respectively, weighing only 14 and 48.5 pounds designed to strike targets illuminated by a laser. These can carry high explosive, armour-penetrating shaped charges, or (on the MAM-L) lung-rupturing thermobaric warheads, while remaining light enough to mount on relatively small drones. The larger MAM-L can also extend range from 5 to 8.6 miles by using GPS or inertial guidance. Syrian air defenses have managed to shoot down at least three Turkish Anka-S drones in February, and Damascus claims as many as six. As these are larger and newer drones, their loss may be keenly felt, but obviously less so than manned aircraft. https://www.uasvision.com/2020/03/06/turkish-drones-destroy-russian-made-air-defense-systems/

  • Shipbuilding suppliers need more than market forces to stay afloat

    Shipbuilding suppliers need more than market forces to stay afloat

    By: Bryan Clark and Timothy A. Walton The U.S. Navy's award this month of the contract for its new class of frigates starts the very necessary process of rebalancing the U.S. surface fleet, but the competition also highlighted the U.S. shipbuilding-industrial base's increasing fragility. If they lost, two of the four shipyards bidding on the frigate were at risk of either going out of business or joining the underemployed ranks of U.S. commercial shipbuilders. Due to specialization, only one or two yards construct each class of Navy combat ship with workforces, equipment, and infrastructure that would be expensive and difficult to adapt. A decision on any single ship class, as with the frigate, can shut down a shipyard and send its workers to the unemployment line. Specialization is also a problem when orders increase. The Navy's two submarine shipyards, General Dynamics Electric Boat and Huntington Ingalls Industries' Newport News division, shrank the time needed to build subs by 20 percent during the past decade while increasing production to two per year. The rising sophistication of Virginia-class submarines has now reversed this trend, however, and submarine builders' challenges are only increasing. They recently started a new contract to build up to 10 of the larger Block V Virginia submarines and are in negotiation with the Navy on a block-buy contract for the first two Columbia-class ballistic missile submarines. Supplier challenges abound U.S. shipbuilders may be fragile, but their suppliers are on life support. After decades of being whipsawed by changes to shipbuilding plans and budget uncertainty, a shrinking number of suppliers are able and willing to stay in business. The Navy's recent initiatives to improve supplier production capacity and resilience don't go far enough to address its rising dependence on sole-source suppliers, which now provide more than 75 percent of submarine parts. For example, when problems with Columbia missile tubes led the Navy to seek new suppliers, it replaced the existing, sole source — BWXT — with another — General Dynamics — that will assemble tubes at the same facilities that are constructing parts for the Virginia and Columbia submarines. Last year, the Trump administration used the Defense Production Act to establish new suppliers for military missile fuel. The Navy should build on this effort to identify sole-source items for which an additional supplier is appropriate. In selecting additional suppliers, the Navy should prioritize attributes other than cost. Sole-source items by definition are important enough to justify seeking out or creating a single supplier rather than adapting the ship's design to use an existing item. Therefore, the Navy should emphasize the provider's track record in conducting similar or other challenging engineering; its ability to adjust to what will likely be variable demand and changing specifications; and the likelihood of quality production that avoids rework. Planning for resiliency The Department of Defense could help address the shipbuilding-industrial base's fragility with its current study of the number and mix of ships needed in the future fleet. Although the primary goal of this analysis should be determining the most effective fleet possible within likely budget constraints, it must also ensure the industrial base can build and sustain the future Navy. Industrial base considerations are not new to Navy force structure planning. During the last decade, the Navy or Congress added amphibious ships, submarines, destroyers and auxiliary vessels to maintain hot production lines or keep a shipyard afloat until the next order. Each of the Navy's new combatant ships are expected to cost more than $1 billion to build, constraining the Navy's ability to spread ship construction to other qualified shipyards to fill production gaps or extend classes to keep a shipyard in operation. The Navy could better support shipbuilders by rebalancing its fleet architecture to increase the number of smaller vessels such as corvettes or tank landing ships, and reduce the number of larger destroyers and amphibious warships. Smaller, less-expensive ships could be built in larger numbers per year, providing more flexibility in shipbuilding plans to stabilize the workload for shipbuilders and providing more scalability to align shipbuilding expenditures with changing budgets. Smaller ships could also be built at a wider range of shipyards, including those that only build commercial vessels and noncombatant government ships like Coast Guard cutters and oceanographic research vessels. These “dual-use” shipbuilders suffer today from a lack of coordination between commercial and government shipbuilding, which creates a feast-or-famine cycle of orders. The Navy and nation depend on a healthy shipbuilding-industrial base. To foster the industrial base in the face of natural and man-made challenges, the Navy should change its fleet design and shipbuilding plans, while investing to establish and qualify new suppliers. Without deliberate action, the U.S. shipbuilding industry will become increasingly fragile, limiting the Navy's ability to build the ships it needs and respond when today's competitions turn to conflict.
