Navy\u2014solid state lasers (SSLs), the electromagnetic railgun (EMRG), and the gun-launched guided projectile (GLGP), also known as the hypervelocity projectile (HVP)\u2014could substantially improve the ability of Navy surface ships to defend themselves against surface craft, unmanned aerial vehicles (UAVs), and eventually anti-ship cruise missiles (ASCMs).\nThe Navy has been developing SSLs for several years, and in 2014 installed on a Navy ship its first prototype SSL capable of countering surface craft and UAVs. The Navy since then has been developing and installing additional SSL prototypes with improved capability for countering surface craft and UAVs. Higher-power SSLs being developed by the Navy are to have a capability for countering ASCMs. Current Navy efforts to develop SSLs include\nthe Solid State Laser Technology Maturation (SSL-TM) effort;\nthe Optical Dazzling Interdictor, Navy (ODIN);\nthe Surface Navy Laser Weapon System (SNLWS) Increment 1, also known as the high-energy laser with integrated optical dazzler and surveillance (HELIOS); and\nthe High Energy Laser Counter-ASCM Program (HELCAP).\nThe first three efforts above are included in what the Navy calls the Navy Laser Family of Systems (NFLoS) effort. NFLOS and HELCAP, along with technologies developed by other parts of DOD, are to support the development of future, more capable shipboard lasers.\nThe Navy has been developing EMRG for several years. It was originally conceived as a naval surface fire support (NSFS) weapon for supporting Marines and other friendly forces ashore. Subsequently, it was determined that ERGM could also be used for air and missile defense, which strengthened Navy interest in ERGM development. The Navy is continuing development work on ERGM, but it is unclear when production-model ERGMs will be installed on Navy ships.\nAs the Navy was developing EMRG, it realized that the guided projectile being developed for EMRG could also be fired from powder guns, including 5-inch guns on Navy cruisers and destroyers and 155 mm artillery guns operated by the Army and Marine Corps. When fired from powder guns, the projectile does not fly as quickly as it does when fired from an ERGM, but it still flies quickly enough to be of use as an air-defense weapon. The concept of firing the projectile from powder guns is referred to as GLGP and HVP. One potential advantage of HVP/GLGP is that, once developed, it can be rapidly deployed on Navy cruisers and destroyers and in Army and Marine Corps artillery units, because the powder guns in question already exist.\nIn addition to the question of whether to approve, reject, or modify the Navy\u2019s FY2021 funding requests for SSLs, ERGM, and HVP/GLGP, issues for Congress include the following:\nwhether the Navy is moving too quickly, too slowly, or at about the right speed in its efforts to develop these weapons;\nthe Navy\u2019s plans for transitioning these weapons from development to procurement and fielding of production models aboard Navy ships; and\nwhether Navy the Navy\u2019s shipbuilding plans include ships with appropriate amounts of space, weight, electrical power, and cooling capacity to accommodate these weapons.", "type": "CRS Report", "typeId": "REPORTS", "active": true, "formats": [ { "format": "HTML", "encoding": "utf-8", "url": "https://www.crs.gov/Reports/R44175", "sha1": "a18072dc69af58d4d22cce679fbd7b07a527321e", "filename": "files/20200402_R44175_a18072dc69af58d4d22cce679fbd7b07a527321e.html", "images": { "/products/Getimages/?directory=R/html/R44175_files&id=/1.png": "files/20200402_R44175_images_6ca82c07e30c681450ae89a7e267aee7d79a6125.png", "/products/Getimages/?directory=R/html/R44175_files&id=/3.png": "files/20200402_R44175_images_3234dde32a8bafc8db2f3ad2b1a4cd5fc8a93700.png", "/products/Getimages/?directory=R/html/R44175_files&id=/0.png": "files/20200402_R44175_images_babab05a32ccad87decc7465df7a55f3ee5cab6c.png", "/products/Getimages/?directory=R/html/R44175_files&id=/17.png": "files/20200402_R44175_images_045da5f481a7e534754147a1b0182bcf0dba8661.png", "/products/Getimages/?directory=R/html/R44175_files&id=/9.png": "files/20200402_R44175_images_e8ea121d8df4347cdc139d14702dd591fda1b4d0.png", "/products/Getimages/?directory=R/html/R44175_files&id=/13.png": "files/20200402_R44175_images_9108e150328694bdfb7696504274daeb3f298edf.png", "/products/Getimages/?directory=R/html/R44175_files&id=/14.png": "files/20200402_R44175_images_5c9dde560e891a9fd58b89ae3d32e6fda5ea5bff.png", "/products/Getimages/?directory=R/html/R44175_files&id=/7.png": "files/20200402_R44175_images_c20a7e041fe850cc4743107376d6a3291ccef39f.png", "/products/Getimages/?directory=R/html/R44175_files&id=/4.png": "files/20200402_R44175_images_aa9ae58593f69640ec20f1ec55dae9153b5a249b.png", "/products/Getimages/?directory=R/html/R44175_files&id=/8.png": "files/20200402_R44175_images_723db9057bf6b4b93e562b6cb49010713c30a664.png", "/products/Getimages/?directory=R/html/R44175_files&id=/5.png": "files/20200402_R44175_images_178887a7a89951a169a24e9c53e90cfd4e680adb.png", "/products/Getimages/?directory=R/html/R44175_files&id=/16.png": "files/20200402_R44175_images_4511327f69437aa00c95b32059b38184adb1fe12.png", "/products/Getimages/?directory=R/html/R44175_files&id=/11.png": "files/20200402_R44175_images_15030d177a2e1f6df58a707a000a37a1ce477142.png", "/products/Getimages/?directory=R/html/R44175_files&id=/15.png": "files/20200402_R44175_images_87642b746ff0362d3e15e9fa10b24047ffbf068a.png", "/products/Getimages/?directory=R/html/R44175_files&id=/6.png": "files/20200402_R44175_images_442c642adbd2c988bb03c0bf3918d50da575cf4b.png", "/products/Getimages/?directory=R/html/R44175_files&id=/12.png": "files/20200402_R44175_images_a37d0f0eced0d6ec007b103d6009d7976f0a66eb.png", "/products/Getimages/?directory=R/html/R44175_files&id=/10.png": "files/20200402_R44175_images_34137beded237d5add1ea49654ab390754b9c889.png", "/products/Getimages/?directory=R/html/R44175_files&id=/2.png": "files/20200402_R44175_images_379bb64b425aba8256bd310bd523662b884da71a.png" } }, { "format": "PDF", "encoding": null, "url": "https://www.crs.gov/Reports/pdf/R44175", "sha1": "3325832780da1f708a846eb251b24cb566c725fc", "filename": "files/20200402_R44175_3325832780da1f708a846eb251b24cb566c725fc.pdf", "images": {} } ], "topics": [ { "source": "IBCList", "id": 4902, "name": "Air, Land, Sea, & Projection Forces" } ] }, { "source": "EveryCRSReport.com", "id": 611576, "date": "2019-12-17", "retrieved": "2019-12-20T16:29:31.804959", "title": "Navy Lasers, Railgun, and Gun-Launched Guided Projectile: Background and Issues for Congress", "summary": "Three new ship-based weapons being developed by the Navy\u2014solid state lasers (SSLs), the electromagnetic railgun (EMRG), and the gun-launched guided projectile (GLGP), also known as the hypervelocity projectile (HVP)\u2014could substantially improve the ability of Navy surface ships to defend themselves against surface craft, unmanned aerial vehicles (UAVs), and eventually anti-ship cruise missiles (ASCMs).\nThe Navy has been developing SSLs for several years, and in 2014 installed on a Navy ship a prototype SSL called the Laser Weapon System (LaWS) that was capable of countering surface craft and UAVs.

Navy\u2014solid state lasers (SSLs), the electromagnetic railgun (EMRG), and the gun-launched guided projectile (GLGP), also known as the hypervelocity projectile (HVP)\u2014could substantially improve the ability of Navy surface ships to defend themselves against surface craft, unmanned aerial vehicles (UAVs), and eventually anti-ship cruise missiles (ASCMs).\nThe Navy has been developing SSLs for several years, and in 2014 installed on a Navy ship a prototype SSL called the Laser Weapon System (LaWS) that was capable of countering surface craft and UAVs. The Navy is now developing SSLs with improved capability for countering surface craft and UAVs, and eventually a capability for countering ASCMs. Navy efforts to develop these more capable lasers include\nthe Solid State Laser Technology Maturation (SSL-TM) effort;\nthe Ruggedized High Energy Laser (RHEL);\nthe Optical Dazzling Interdictor, Navy (ODIN);\nthe Surface Navy Laser Weapon System (SNLWS) Increment 1, also known as the high-energy laser with integrated optical dazzler and surveillance (HELIOS); and\nthe High Energy Laser Counter-ASCM Program (HELCAP).\nThe Navy refers to the first four efforts above collectively as the Navy Laser Family of Systems (NFLoS). Under the Navy\u2019s laser development approach, NFLOS and HELCAP, along with technologies developed by other parts of DOD, are to support the development of future, more capable shipboard lasers.\nThe Navy has been developing EMRG for several years. It was originally conceived as a naval surface fire support (NSFS) weapon for supporting Marines and other friendly forces ashore. Subsequently, it was determined that ERGM could also be used for air and missile defense, which strengthened interest in ERGM development. More recently, it was determined that the projectile to be fired by ERGM could also be fired by existing powder-propellant guns, including 5-inch and 155 mm guns on Navy cruisers and destroyers, and 155 mm artillery guns operated by the Army and Marine Corps. When fired from power guns, the projectile does not fly as quickly as it does when fired from an ERGM, but it still flies quickly enough to be of use as an air-defense weapon. The concept of firing the projectile from powder guns is referred to as GLGP and HVP. One potential advantage of HVP/GLGP is that, once developed, it can be rapidly deployed on Navy cruisers and destroyers and in Army and Marine Corps artillery units, because the powder guns in question already exist.\nIn addition to the question of whether to approve, reject, or modify the Navy\u2019s FY2020 funding requests for SSLs, ERGM, and HVP/GLGP, issues for Congress include the following:\nwhether the Navy is moving too quickly, too slowly, or at about the right speed in its efforts to develop these weapons;\nthe Navy\u2019s plans for transitioning these weapons from development to procurement and fielding aboard Navy ships;

"2019-05-20T22:08:42.977119", "title": "Navy Lasers, Railgun, and Gun-Launched Guided Projectile: Background and Issues for Congress", "summary": "Three new ship-based weapons being developed by the Navy\u2014solid state lasers (SSLs), the electromagnetic railgun (EMRG), and the gun-launched guided projectile (GLGP), also known as the hypervelocity projectile (HVP)\u2014could substantially improve the ability of Navy surface ships to defend themselves against surface craft, unmanned aerial vehicles (UAVs), and eventually anti-ship cruise missiles (ASCMs).\nThe Navy has been developing SSLs for several years, and in 2014 installed on a Navy ship a prototype SSL called the Laser Weapon System (LaWS) that was capable of countering surface craft and UAVs. The Navy is now developing SSLs with improved capability for countering surface craft and UAVs, and eventually a capability for countering ASCMs. Navy efforts to develop these more capable lasers include\nthe Solid State Laser Technology Maturation (SSL-TM) effort;\nthe Ruggedized High Energy Laser (RHEL);\nthe Optical Dazzling Interdictor, Navy (ODIN);\nthe Surface Navy Laser Weapon System (SNLWS) Increment 1, also known as the high-energy laser with integrated optical dazzler and surveillance (HELIOS); and\nthe High Energy Laser Counter-ASCM Program (HELCAP).\nThe Navy refers to the first four efforts above collectively as the Navy Laser Family of Systems (NFLoS). Under the Navy\u2019s laser development approach, NFLOS and HELCAP, along with technologies developed by other parts of DOD, are to support the development of future, more capable shipboard lasers.\nThe Navy has been developing EMRG for several years. It was originally conceived as a naval surface fire support (NSFS) weapon for supporting Marines and other friendly forces ashore. Subsequently, it was determined that ERGM could also be used for air and missile defense, which strengthened interest in ERGM development. More recently, it was determined that the projectile to be fired by ERGM could also be fired by existing powder-propellant guns, including 5-inch and 155 mm guns on Navy cruisers and destroyers, and 155 mm artillery guns operated by the Army and Marine Corps. When fired from power guns, the projectile does not fly as quickly as it does when fired from an ERGM, but it still flies quickly enough to be of use as an air-defense weapon. The concept of firing the projectile from powder guns is referred to as GLGP and HVP. One potential advantage of HVP/GLGP is that, once developed, it can be rapidly deployed on Navy cruisers and destroyers and in Army and Marine Corps artillery units, because the powder guns in question already exist.\nIn addition to the question of whether to approve, reject, or modify the Navy\u2019s FY2020 funding requests for SSLs, ERGM, and HVP/GLGP, issues for Congress include the following:\nwhether the Navy is moving too quickly, too slowly, or at about the right speed in its efforts to develop these weapons;\nthe Navy\u2019s plans for transitioning these weapons from development to procurement and fielding aboard Navy ships; and\nwhether Navy the Navy\u2019s shipbuilding plans include ships with appropriate amounts of space, weight, electrical power, and cooling capacity to accommodate these weapons.", "type": "CRS Report", "typeId": "REPORTS", "active": true, "formats": [ { "format": "HTML", "encoding": "utf-8", "url": "https://www.crs.gov/Reports/R44175", "sha1": "cc59843b19d3be42fbe2c3164901567b1f8d433d", "filename": "files/20190517_R44175_cc59843b19d3be42fbe2c3164901567b1f8d433d.html", "images": { "/products/Getimages/?directory=R/html/R44175_files&id=/1.png": "files/20190517_R44175_images_8ea91cae3bafd0ca2f1ed2aa42e40102cde950e0.png", "/products/Getimages/?directory=R/html/R44175_files&id=/3.png": "files/20190517_R44175_images_2f0333a0febf51f4aa80501c11c2ec753f55580c.png", "/products/Getimages/?directory=R/html/R44175_files&id=/0.png": "files/20190517_R44175_images_23fff998a6a37aeef50c99005ec8dff64fd834f9.png", "/products/Getimages/?directory=R/html/R44175_files&id=/9.png": "files/20190517_R44175_images_1f02c57962b5805859388a4221b91a8d8a37a6ee.png", "/products/Getimages/?directory=R/html/R44175_files&id=/13.png": "files/20190517_R44175_images_d5a044af25af1028ccae390327946a5f1a50e42f.png", "/products/Getimages/?directory=R/html/R44175_files&id=/7.png": "files/20190517_R44175_images_cf5aa81808aff240a3e833eb5de59f7799ddfd8c.png", "/products/Getimages/?directory=R/html/R44175_files&id=/4.png": "files/20190517_R44175_images_f8725888021be534f6858cb448b8f7d470f1b1e4.png", "/products/Getimages/?directory=R/html/R44175_files&id=/8.png": "files/20190517_R44175_images_afc95a052bb5ccd6932f20fb944c25c52840816f.png", "/products/Getimages/?directory=R/html/R44175_files&id=/5.png": "files/20190517_R44175_images_d8c403cca7e8c6101043f8e0bdb4ffb845da493a.png", "/products/Getimages/?directory=R/html/R44175_files&id=/11.png": "files/20190517_R44175_images_183ddd0f6646aeafa1f023839e2bdfb305a20218.png", "/products/Getimages/?directory=R/html/R44175_files&id=/6.png": "files/20190517_R44175_images_0dfcecd951cf59bbec4a9678b51ca31bb6f9bc50.png", "/products/Getimages/?directory=R/html/R44175_files&id=/12.png": "files/20190517_R44175_images_65d9f583276d3a1fa74b79f30de6402b4f4f6de6.png", "/products/Getimages/?directory=R/html/R44175_files&id=/10.png": "files/20190517_R44175_images_f056823a0e416b67b8d68d173b4eec01915b0294.png", "/products/Getimages/?directory=R/html/R44175_files&id=/2.png": "files/20190517_R44175_images_2a7100f8ef4c2791e9ae7843ef267e1ce0535da4.png" } }, { "format": "PDF", "encoding": null, "url": "https://www.crs.gov/Reports/pdf/R44175", "sha1": "75b9d93fd620a2b55d67619f76c14c67aa4a4104", "filename": "files/20190517_R44175_75b9d93fd620a2b55d67619f76c14c67aa4a4104.pdf", "images": {} } ], "topics": [ { "source": "IBCList", "id": 4902, "name": "Air, Land, Sea, & Projection Forces" } ] }, { "source": "EveryCRSReport.com", "id": 586677, "date": "2018-10-23", "retrieved": "2019-04-18T13:32:45.585262", "title": "Navy Lasers, Railgun, and Gun-Launched Guided Projectile: Background and Issues for Congress", "summary": "The Navy is developing three new ship-based weapons that could improve the ability of Navy surface ships to defend themselves against missiles, unmanned aerial vehicles (UAVs), and surface craft: the Surface Navy Laser Weapon System (SNLWS), the electromagnetic railgun (EMRG), and the gun-launched guided projectile (GLGP), previously known as the hypervelocity projectile (HVP).\nThe Navy refers to the initial (i.e., Increment 1) version of SNLWS as HELIOS, an acronym meaning high-energy laser with integrated optical dazzler and surveillance.

If two or three of them are successfully developed and deployed, the result might be considered not just a game changer, but a revolution. Rarely has the Navy had so many potential new types of surface-ship missile-defense weapons simultaneously available for development and potential deployment.\nAlthough the Navy in recent years has made considerable progress in developing SSLs, EMRG, and HVP, a number of significant development challenges remain. Overcoming these challenges will likely require years of additional development work, and ultimate success in overcoming them is not guaranteed.\nThe issue for Congress is whether to approve, reject, or modify the Navy\u2019s funding requests and proposed acquisition strategies for these three potential new weapons. Potential oversight questions for Congress include the following:\nUsing currently available approaches for countering anti-ship cruise missiles (ASCMs) and anti-ship ballistic missiles (ASBMs), how well could Navy surface ships defend themselves in a combat scenario against an adversary such as China that has large numbers of ASCMs (including advanced models) and ASBMs?
