to the U.S. Bureau of Naval Research (ONR), said the U.S. Navy plans to next month with the industrial sector in seeking help to develop more high-power free electron laser for ship defense.
According to the spokesman, Colin? Bo Bu said that the U.S. Navy Research Council plans to publish a "wide range of announcement" (BAA), to seek assistance to develop up to 100kW of power free electron laser. The notice will also focus on more high-power laser, that is, "scalability."
According to the U.S. Naval Research Bureau Director William Landay last August to the United States will be "at home and military," said U.S. Navy Research Council, the ultimate goal is the development of megawatt-class free electron laser. However, the main medium-term phase is to achieve up to 100kW of power free electron laser. U.S. Department of Energy's Jefferson Lab researchers have developed a technology to give at least 14kW of infrared laser. The lab is located in Newport News, Virginia.
According to the U.S. Office of Naval Research published in the website, free electron laser can provide a strong laser beam, the laser beam can be adjusted to a precise wavelength. Compared with traditional laser, free electron laser can be more accurately controlled, resulting in high accuracy, strong power of the laser.
U.S. Navy Research Council ultimately hopes to develop MW free electron laser, used "ships, offshore platforms should cruise missiles, ballistic missile defense threats, and flocks of small boats"
According to Landay said issued "notices wide range", the U.S. Navy Research Council to prepare for a competitive edge, "innovative naval prototype" project tenders to research and development of 100kW power lasers.
U.S. Navy Science and Technology Committee approved the prototype in late summer this year, work started in the 2010 fiscal year, before the start of the work required to further technology development, and to ensure that funds are available.
In 2006, according to the U.S. "missile defense insider" reports, the U.S. Naval Research Laboratory (ONR) directed energy project leader Quentin Saulter said the free-electron laser (FEL) will be deployed in 2020 to become the enemy ship missile defense weapons, and eventually will be installed in such as DD (X) and other next-generation destroyer and the CVN? 21 class aircraft carrier.
The laser has recently been placed in the U.S. Department of Energy, "Thomas National Accelerator" experimental facilities, it is directed by the ONR is responsible for providing funds to plan, but the same research for the Army, Air Force, industry and academic research use.
The laser wavelength is its flexibility and superior to other types of laser weapons, the main reason. Saulter, said, FEL provides strong beam can be tuned to a specific wavelength, and obtained than from conventional laser beam power higher, FEL can be tuned to different wavelengths of capacity to make it more reasonable to ship defense laser Type?? because its beam from atmospheric interference, such interference in the sea is very serious. Their research showed that? In offshore operations, limits the thermal blooming of high energy laser beam propagation in the atmosphere, therefore, also limit the effectiveness of laser weapons. The traditional DF chemical laser wavelength of the coastal environment is not the best, so at least 60% of the transmission power during the attack by atmospheric scattering.
"Missile defense insider" reports that after 20 years of development, the U.S. Navy has already built a megawatt-class DF chemical laser (MIRACL) and the sea rock beam directional devices (SLBD), now they are constituted at the White Sands, New Mexico Missile Range in the "high-energy laser system test equipment," one of the main weapons have been used to test and validate the concept of several laser weapons.
As the operational environment in recent years, tremendous changes have taken place in the U.S. Navy began to shift its operations, from the coastal ocean into combat operations and operational forms of transition from the offensive naval ships self-defense, therefore, deal with the growing cruise missile threatened to become the Navy High Energy Laser weapons program the main objective. Marine applications as lasers, to overcome the effects of the marine environment caused by the transmission is essential. U.S. Navy has been working to develop high-power directed energy technology, but the work of chemical laser wavelength, laser to launch prior to reaching the goal of easily absorbed by the atmosphere, so had to abandon the development of high-power chemical laser weapons, but using lasers to protect ships against cruise missiles in research funding has not given up. FEL related to the emergence of institutions that the U.S. Navy is a better alternative. June 2005, FEL was 25 kW infrared laser and a laser kind in the world the highest laser power.
Naval Research Rear manager Jay Cohen in May 2005 an industry conference, said, "We will in the next five years to reach 100 kW, which is the minimum necessary power of anti-."
December 19, 2005, the U.S. Navy's new minister of war, Mike? Mullen reported to Congress the future of the Navy ships program. According to the U.S. Navy budget for 2035 years ago, the Navy will maintain a fleet of 313 ships, including: 11 nuclear-powered aircraft carriers, 19 cruisers, 62 destroyers, seven DD (X) on the landing assault ship, 48 boats attack submarines, 14 ballistic missile submarines, four SSGN nuclear submarines, 10 LPD? 17 amphibious ships, 12 ships at sea and a variety of preset command, control and support ship. Although the number of ships will ship with the retirement of the old and the new ship procurement changes slightly each year, but generally not less than 300. Which include the DD (X) on the landing assault ship, LPD? 17 amphibious ships, including all-electric model will account for future ships a large percentage.
