The United States Naval Research Laboratory (NRL) is the corporate research laboratory for the United States Navy and the United States Marine Corps. It conducts basic scientific research, applied research, technological development and prototyping. The laboratory's specialties include plasma physics, space physics, materials science, and tactical electronic warfare. NRL is one of the first US government scientific R&D laboratories, having opened in 1923 at the instigation of Thomas Edison, and is currently under the Office of Naval Research. billion per year.NRL is a Navy Working Capital Fund activity. All costs, including overhead, are recovered through sponsor-funded research projects. NRL’s research expenditures are approximately $1
The Naval Research Laboratory conducts a variety of basic and scientific research and technological development of importance to the Navy. It has a history of scientific breakthroughs and technological achievements dating back to its foundation in 1923.In some instances the laboratory's contributions to military technology have been declassified decades after those technologies have become widely adopted. In 2011, NRL researchers published 1,398 unclassified scientific and technical articles, book chapters and conference proceedings. In 2008, the NRL was ranked No. 3 among all U.S. institutions holding nanotechnology-related patents, behind IBM and the University of California.
Current areas of research at NRL include:
In 2014, the NRL was researching: armor for munitions in transport, high-powered lasers, remote explosives detection, spintronics, the dynamics of explosive gas mixtures, electromagnetic railgun technology, detection of hidden nuclear materials, graphene devices, high-power extremely high frequency (35–220 GHz) amplifiers, acoustic lensing, information-rich orbital coastline mapping, arctic weather forecasting, global aerosol analysis & prediction, high-density plasmas, millisecond pulsars, broadband laser data links, virtual mission operation centers, battery technology, photonic crystals, carbon nanotube electronics, electronic sensors, mechanical nano-resonators, solid-state chemical sensors, organic opto-electronics, neural-electronic interfaces and self-assembling nanostructures.
The laboratory includes a range of R&D facilities. 2014 additions included the NRL Nanoscience Institute's 5,000 sq ft (460 m2) Class 100 nanofabrication cleanroom; quiet and ultra-quiet measurement labs; and the Laboratory for Autonomous Systems Research (LASR).
The Naval Research Laboratory has a long history of spacecraft development. This includes the second, fifth and seventh American satellites in Earth orbit, the first solar-powered satellite, the first surveillance satellite, the first meteorological satellite and the first GPS satellite. Project Vanguard, the first American satellite program, tasked NRL with the design, construction and launch of an artificial satellite, which was accomplished in 1958. As of 2013 [update] , Vanguard I and its upper launch stage are still in orbit, making them the longest-lived man-made satellites. Vanguard II was the first satellite to observe the Earth's cloud cover and therefore the first meteorological satellite. NRL's Galactic Radiation and Background I (GRAB I) was the first U.S. intelligence satellite, mapping out Soviet radar networks from space. The Global Positioning System (GPS) was invented at NRL and tested by NRL's Timation series of satellites. The first operational GPS satellite, Timation IV (NTS-II) was designed and constructed at NRL.
NRL pioneered the study of the sun Ultraviolet and X-Ray spectrum and continues to contribute to the field with satellites like Coriolis (satellite) launched in 2003. NRL is also responsible for the Tactical Satellite Program with spacecraft launched in 2006, 2009 and 2011.
The NRL designed the first satellite tracking system, Minitrack, which became the prototype for future satellite tracking networks. Prior to the success of surveillance satellites, the iconic parabolic antenna atop NRL's main headquarters in Washington, D.C. was part of Communication Moon Relay, a project that utilized signals bounced off the Moon both for long-distance communications research and surveillance of internal Soviet transmissions during the Cold War.
NRL's spacecraft development program continues today with the TacSat-4 experimental tactical reconnaissance and communication satellite. In addition to spacecraft design, NRL designs and operates spaceborne research instruments and experiments, such as the Strontium Iodide Radiation Instrumentation (SIRI) and RAM Angle and Magnetic field sensor (RAMS) aboard STPSat-5,the Wide-field imager for solar probe (WISP) aboard the Parker Solar Probe, and the Large Angle and Spectrometric Coronagraph Experiment (LASCO) aboard the Solar and Heliospheric Observatory (SOHO). NASA's Fermi Gamma-ray Space Telescope (FGST) [formerly called Gamma-ray Large Area Space Telescope (GLAST)] was tested at NRL spacecraft testing facilities. NRL scientists have most recently contributed leading research to the study of novas and gamma ray bursts.
The Marine Meteorology Division (Naval Research Lab–Monterey, NRL–MRY), located in Monterey, California, contributes to weather forecasting in the United States and around the world by publishing imagery from 18 weather satellites. Satellite images of severe weather (e.g. hurricanes and cyclones) that are used for advanced warning often originate from NRL–MRY, as seen in 2017 during hurricane Harvey.NRL is also involved in weather forecasting models such as the Hurricane Weather Research and Forecasting model released in 2007.
NRL has a long history of contributions to materials science, dating back to the use of Industrial radiography with gamma rays for the nondestructive inspection of metal casings and welds on Navy vessels beginning in the 1920s. Modern mechanical fracture mechanics were pioneered at NRL and were subsequently applied to solve fracture problems in Navy vessels, commercial aircraft and Polaris missiles. That knowledge is in widespread use today in applications ranging from design of nuclear reactors to aircraft, submarines and toxic material storage tanks.NRL developed the synthesis of high-purity GaAs crystals used in a myriad of modern high frequency transceivers including cellular phones, satellite communication systems, commercial and military radar systems including those aboard all US combat aircraft and ARM, Phoenix, AIM-9L and AMRAAM missiles. NRL's GaAs inventions were licensed by Rockwell, Westinghouse, Texas Instruments and Hughes Research. High-purity GaAs is also used for high-efficiency solar cells like those aboard NASA's Spirit and Opportunity rovers currently on Mars.
Fundamental aspects of stealth technology were developed at NRL, including the radar absorption mechanisms in ferrite-containing materials.Metal bearing surface treatments using Cr ion implantation researched at NRL nearly tripled the service life of Navy turbine engine parts and was adopted for Army helicopter parts as well. Fluorinated polyurethane coatings developed at NRL are used to line fuel storage tanks throughout the US Navy, reducing leakage and environmental and fuel contamination. The same polymer films are used in Los Angeles-class submarine radomes to repel water and enable radar operation soon after surfacing.
Scientists at NRL frequently contribute theoretical and experimental research on novel materials,particularly magnetic materials and nanomaterials and thermoplastic.
The first modern U.S. radar was invented and developed at NRL in Washington, DC in 1922. By 1939, NRL installed the first operational radar aboard the USS New York, in time for radar to contribute to naval victories of the Coral Sea, Midway and Guadalcanal. NRL then further developed over-the-horizon radar as well as radar data displays.NRL's Radar Division continues important research & development contributing to US Navy and US Department of Defense capabilities.
NRL's Tactical Electronic Warfare (TEW) Divisionis responsible for research and development in support of the Navy's tactical electronic warfare requirements and missions. These include electronic warfare support measures, electronic countermeasures, and supporting counter-countermeasures, as well as studies, analyses, and simulations for determining and improving the performance of Electronic Warfare systems. NRL TEW includes aerial, surface, and ground EW within its scope. NRL is responsible for the identification, friend or foe (IFF) system and a number of other advances.
The Information Technology Divisionfeatures an information security R&D group, which is where the IETF's IP Security (IPsec) protocols were originally developed. The Encapsulating Security Payload (ESP) protocol developed at NRL is widely used for virtual private network (VPN) connections worldwide. The projects developed by the laboratory often become mainstream applications without public awareness of the developer; an example in computer science is onion routing, the core principle of the anonymizing Tor software.
Nuclear power research was initiated at NRL as early as 1939,six years before the first atomic bomb, for the purpose of powering submarines. Uranium enrichment methods sponsored by NRL over the course of World War II were adopted by the Manhattan Project and guided the design of Oak Ridge National Laboratory's Uranium enrichment plant. NRL is currently developing laser focusing techniques aimed at inertial confinement fusion technology.
The static discharger seen on trailing edges of virtually all modern aircraft was originally developed by NRL scientists during World War II. After the war, the laboratory developed modern synthetic lubricantsinitially for use in the Navy's jet aircraft but subsequently adopted by the commercial jet industry.
In the late 1960s, NRL researched low-temperature physics, achieving for the first time a temperature within one millionth of a degree of absolute zero in 1967. In 1985 two scientists at the laboratory, Herbert A. Hauptman and Jerome Karle, won the Nobel Prize for devising direct methods employing X-ray diffraction analysis in the determination of crystal structures.Their methods form the basis for the computer packages used in pharmaceutical labs and research institutions worldwide for the analysis of more than 10,000 new substances each year.
NRL has most recently published research on quantum computing,quantum dots, plasma shockwaves, thermodynamics of liquids, modeling of oil spills and other topics.
NRL operates a small squadron of research aircraft termed Scientific Development Squadron (VXS) 1. Its missions include, for example, Rampant Lion, which used sophisticated airborne instrumentation (gravimeters, magnetometers and hyperspectral cameras) to collect precise 3D topography of two-thirds of Aghanistan and locate natural resources (underground gas and mineral deposits, vegetation types, etc.) thereand in Iraq and Colombia.
The Division of Plasma Science conducts research and development into ionized matter. NRL currently holds the world record for most energetic rail gun projectile (33 MJ, 9.2 kWh) and fastest man-made projectile (2.24 million mph, 3.60 million km/h).
NRL established the Navy Center for Applied Research in Artificial Intelligence in 1981,which conducts basic and applied research in artificial intelligence, cognitive science, autonomy, and human-centered computing. Among its achievements are advances in cognitive architectures, human-robot interaction, and machine learning.
The laboratory is divided into four research directorates, one financial directorate, and one executive directorate. All the directorates are headquartered in Washington, D.C. Many directorates have other facilities elsewhere, primarily at either the Stennis Space Center in Bay St Louis, Mississippi or in Monterey, California.
Most NRL staff are civilians in the civil service, with a relatively small number of Navy enlisted personnel or officers. In addition, there are some support contractors that work on-site at NRL. As of 31 December 2015, across all NRL locations, NRL had 2540 civilian employees (i.e., not including civilian contractors).On the same date, there were 35 military officers on-board NRL and 58 enlisted on-board NRL, most of whom are with NRL's VXS-1 Scientific Flight Detachment, which is located at the Patuxent River ('Pax River') Naval Air Station (NAS) in southern Maryland.
NRL has special authority to use a Pay-Band pay system instead of using the traditional General Schedule (GS) pay system for its civilian employees.This gives NRL more ability to pay employees based on performance and merit, rather than time-in-grade or some other seniority metric. There are several different pay-band groups at NRL, each being for different categories of civilian employees. As of 31 December 2015, NRL had 1615 civilian scientists/engineers in the NP pay system, 103 civilian technicians in the NR pay system, 383 civilian administrative specialists/professionals in the NO pay system, and 238 civilian administrative support staff in the NC pay system.
NRL scientists & engineers typically are in the (NP) pay group in NRL's Pay Band system.The NP-II pay band is equivalent to GS-5 Step 1 through GS-10 Step 10. The NP-III pay band is equivalent to GS-11 Step 1 through GS-13 Step 10. NRL's Pay Band IV corresponds to the GS-14 Step 1 to GS-15 Step 10 pay grades, inclusive, while NRL's Pay Band V can pay above GS-15 Step 10 and corresponds to the Senior Technologist (ST) pay grade elsewhere in the civil service. A new graduate scientist or engineer with a Bachelor of Science degree typically is hired with a salary equivalent to a GS-7, while a new graduate scientist or engineer with a Master of Science degree typically at the equivalent of a GS-11.
According to the NRL Fact Book (2016), of NRL civilian full-time permanent employees, 870 had a doctorate, 417 had a master's, and 576 had a bachelor's as their highest degree.
The laboratory also hosts post-doctoral researchers and was voted #15 in the Best Places to Work PostDocs 2013 survey.
The four research directorates within NRL are:
The two support directorates are:
In April 2001, in a departure from traditional working relationships between NRL scientists, the Institute for Nanoscience was established to conduct multidisciplinary research in the fields of materials, electronics and biology. Scientists may be part of the Nanoscience Institute while still performing research for their respective divisions.
Opened March 2012,the Laboratory for Autonomous Systems Research (LASR) is a 50,000 square foot facility that supports basic and applied research in autonomous systems. The facility supports a wide range of interdisciplinary basic and applied research in autonomous systems to include research in autonomous systems, intelligent autonomy, human-autonomous system interaction and collaboration, sensor systems, power and energy systems, networking and communications, and platforms.
LASR provides unique facilities and simulated environmental high bays (littoral, desert, tropical, and forest) and instrumented reconfigurable high bay spaces to support integration of science and technology components into research prototype systems.
The main campus of NRL is in Washington, DC, near the southernmost part of the District. It is on the Potomac River and is immediately south of (but is not part of) Joint Base Anacostia-Bolling. This campus is immediately north of the Blue Plains site of the DC Water Authority. Exit 1 of northbound I-295 leads directly to Overlook Avenue and the NRL Main Gate. The U.S. Postal Service operates a post office on the NRL main campus.
In addition, NRL operates several field sites and satellite facilities:
Artifacts found on the NRL campus, such as stone tools and ceramic shards, show that the site had been inhabited since the Late Archaic Period. Cecil Calvert, 2nd Baron Baltimore, granted the tract of land which includes the present NRL campus to William Middleton in 1663. It became part of the District of Columbia in 1791, and was purchased by Thomas Grafton Addison in 1795, who named the area Bellevue and built a mansion on the highlands to the east.
Zachariah Berry purchased the land in 1827, who rented it out for various purposes including a fishery at Blue Plains. The mansion was demolished during the Civil War to build Fort Greble. In 1873 the land was purchased by the federal government as the Bellevue Annex to the Naval Gun Factory, and several buildings were constructed including the Commandant's house, "Quarters A", which is still in use today.
The Naval Research Laboratory came into existence from an idea that originated from Thomas Edison. In a May 1915 editorial piece in the New York Times Magazine, Edison wrote; "The Government should maintain a great research laboratory... In this could be developed...all the technique of military and naval progression without any vast expense."This statement addressed concerns about World War I in the United States.
Edison then agreed to serve as the head of the Naval Consulting Board that consisted of civilians who had achieved expertise. The focus of the Naval Consulting Board was as advisor to the U.S. Navy pertaining to science and technology. The board brought forward a plan to create a modern facility for the Navy. In 1916 Congress allocated $1.5 million for implementation. However, construction was delayed until 1920 because of the war and internal disagreements within the board.
The U.S. Naval Research Laboratory, the first modern research institution created within the United States Navy, began operations at 1100 on 2 July 1923. The Laboratory's two original divisions – Radio and Sound – performed research in the fields of high-frequency radio and underwater sound propagation. They produced communications equipment, direction-finding devices, sonar sets, and the first practical radar equipment built in the United States. They performed basic research, participating in the discovery and early exploration of the ionosphere. The NRL gradually worked towards its goal of becoming a broadly based research facility. By the beginning of World War II, five new divisions had been added: Physical Optics, Chemistry, Metallurgy, Mechanics and Electricity, and Internal Communications.
Total employment at the NRL jumped from 396 in 1941 to 4400 in 1946, expenditures from $1.7 million to $13.7 million, the number of buildings from 23 to 67, and the number of projects from 200 to about 900. During World War II, scientific activities necessarily were concentrated almost entirely on applied research. Advances were made in radio, radar, and sonar. Countermeasures were devised. New lubricants were produced, as were antifouling paints, luminous identification tapes, and a sea marking dye to help save survivors of disasters at sea. A thermal diffusion process was conceived and used to supply some of the U-235 isotope needed for one of the first atomic bombs. Also, many new devices that developed from booming wartime industry were type tested and then certified as reliable for the Fleet.
As a result of the scientific accomplishments of the WWII, the United States emerged into the postwar era determined to consolidate its wartime gains in science and technology and to preserve the working relationship between its armed forces and the scientific community. While the Navy was establishing the Office of Naval Research (ONR) as a liaison with and supporter of basic and applied scientific research, the Navy encouraged NRL to broaden its scope since it was the Navy Department's corporate research laboratory. NRL was placed under the administrative oversight of ONR after ONR was created. NRL's Commanding Officer reports to the Navy's Chief of Naval Research (CNR). The Chief of Naval Research leads the Office of Naval Research, which primarily is located in the Ballston area of Arlington, Virginia. The reorganization also caused a parallel shift of the Laboratory's emphasis to one of long-range basic and applied research in the full range of the physical sciences.
However, rapid expansion during the war had left NRL improperly structured to address long-term Navy requirements. One major task – neither easily nor rapidly accomplished – was that of reshaping and coordinating research. This was achieved by transforming a group of largely autonomous scientific divisions into a unified institution with a clear mission and a fully coordinated research program. The first attempt at reorganization vested power in an executive committee composed of all the division superintendents. This committee was impracticably large, so in 1949, a civilian director of research was named and given full authority over the program. Positions for associate directors were added in 1954.
In 1992, the previously separate Naval Oceanographic and Atmospheric Research Laboratory (NOARL), with centers in Bay St. Louis, Mississippi, and Monterey, California, was merged into NRL. Since then, NRL is also the lead Navy center for research in Oceanographic and Atmospheric Sciences, with special strengths in physical oceanography, marine geosciences, ocean acoustics, marine meteorology, and remote oceanic and atmospheric sensing.
Quantum entanglement is the physical phenomenon that occurs when a pair or group of particles is generated, interact, or share spatial proximity in a way such that the quantum state of each particle of the pair or group cannot be described independently of the state of the others, even when the particles are separated by a large distance. The topic of quantum entanglement is at the heart of the disparity between classical and quantum physics.
Metallic hydrogen is a phase of hydrogen in which it behaves like an electrical conductor. This phase was predicted in 1935 on theoretical grounds by Eugene Wigner and Hillard Bell Huntington.
In particle physics, majorons are a hypothetical type of Goldstone boson that are theorized to mediate the neutrino mass violation of lepton number or B − L in certain high energy collisions such as
In physics, topological order is a kind of order in the zero-temperature phase of matter. Macroscopically, topological order is defined and described by robust ground state degeneracy and quantized non-Abelian geometric phases of degenerate ground states. Microscopically, topological orders correspond to patterns of long-range quantum entanglement. States with different topological orders cannot change into each other without a phase transition.
A Majorana fermion, also referred to as a Majorana particle, is a fermion that is its own antiparticle. They were hypothesized by Ettore Majorana in 1937. The term is sometimes used in opposition to a Dirac fermion, which describes fermions that are not their own antiparticles.
The percolation threshold is a mathematical concept in percolation theory that describes the formation of long-range connectivity in random systems. Below the threshold a giant connected component does not exist; while above it, there exists a giant component of the order of system size. In engineering and coffee making, percolation represents the flow of fluids through porous media, but in the mathematics and physics worlds it generally refers to simplified lattice models of random systems or networks (graphs), and the nature of the connectivity in them. The percolation threshold is the critical value of the occupation probability p, or more generally a critical surface for a group of parameters p1, p2, ..., such that infinite connectivity (percolation) first occurs.
Christopher T. Hill is an American theoretical physicist at the Fermi National Accelerator Laboratory who did undergraduate work in physics at M.I.T., and graduate work at Caltech. Hill's Ph.D. thesis, "Higgs Scalars and the Nonleptonic Weak Interactions" (1977) contains the first discussion of the two-Higgs-doublet model.
Alexander Balankin is a Mexican scientist of Russian origin whose work in the field of fractal mechanics and its engineering applications won him the UNESCO Science Prize in 2005.
Ghost imaging is a technique that produces an image of an object by combining information from two light detectors: a conventional, multi-pixel detector that doesn't view the object, and a single-pixel (bucket) detector that does view the object. Two techniques have been demonstrated. A quantum method uses a source of pairs of entangled photons, each pair shared between the two detectors, while a classical method uses a pair of correlated coherent beams without exploiting entanglement. Both approaches may be understood within the framework of a single theory.
Daniel Amihud Lidar is the holder of the Viterbi Professorship of Engineering at the University of Southern California, where he is a Professor of Electrical Engineering, Chemistry, Physics & Astronomy. He is the Director and co-founder of the USC Center for Quantum Information Science & Technology (CQIST) as well as Scientific Director of the USC-Lockheed Martin Quantum Computation Center, notable for his research on control of quantum systems and quantum information processing.
The chameleon is a hypothetical scalar particle that couples to matter more weakly than gravity, postulated as a dark energy candidate. Due to a non-linear self-interaction, it has a variable effective mass which is an increasing function of the ambient energy density—as a result, the range of the force mediated by the particle is predicted to be very small in regions of high density but much larger in low-density intergalactic regions: out in the cosmos chameleon models permit a range of up to several thousand parsecs. As a result of this variable mass, the hypothetical fifth force mediated by the chameleon is able to evade current constraints on equivalence principle violation derived from terrestrial experiments even if it couples to matter with a strength equal or greater than that of gravity. Although this property would allow the chameleon to drive the currently observed acceleration of the universe's expansion, it also makes it very difficult to test for experimentally.
Subir Sachdev is Herchel Smith Professor of Physics at Harvard University specializing in condensed matter. He was elected to the U.S. National Academy of Sciences in 2014, and received the Lars Onsager Prize from the American Physical Society and the Dirac Medal from the ICTP in 2018.
Silicene is a two-dimensional allotrope of silicon, with a hexagonal honeycomb structure similar to that of graphene. Contrary to graphene, silicene is not flat, but has a periodically buckled topology; the coupling between layers in silicene is much stronger than in multilayered graphene; and the oxidized form of silicene, 2D silica, has a very different chemical structure from graphene oxide.
Modern searches for Lorentz violation are scientific studies that look for deviations from Lorentz invariance or symmetry, a set of fundamental frameworks that underpin modern science and fundamental physics in particular. These studies try to determine whether violations or exceptions might exist for well-known physical laws such as special relativity and CPT symmetry, as predicted by some variations of quantum gravity, string theory, and some alternatives to general relativity.
A time crystal or space-time crystal is a structure that repeats in time, as well as in space. Normal three-dimensional crystals have a repeating pattern in space, but remain unchanged as time passes. Time crystals repeat themselves in time as well, leading the crystal to change from moment to moment.

Luk has conducted research on neutrino oscillation and CP violation. Luk and his collaborator Yifang Wang were awarded the 2014 Panofsky Prize “for their leadership of the Daya Bay experiment, which produced the first definitive measurement of θ13 angle of the neutrino mixing matrix.” His work on neutrino oscillation also received 2016 Breakthrough Prize in Fundamental Physics shared with other teams. He also received a Doctor of Science honoris causa from the Hong Kong University of Science and Technology in 2016. Luk is a fellow of the American Physical Society, and the American Academy of Arts and Sciences.
Quantum machine learning is an emerging interdisciplinary research area at the intersection of quantum physics and machine learning. The most common use of the term refers to machine learning algorithms for the analysis of classical data executed on a quantum computer, i.e. quantum-enhanced machine learning. While machine learning algorithms are used to compute immense quantities of data, quantum machine learning increases such capabilities intelligently, by creating opportunities to conduct analysis on quantum states and systems. This includes hybrid methods that involve both classical and quantum processing, where computationally difficult subroutines are outsourced to a quantum device. These routines can be more complex in nature and executed faster with the assistance of quantum devices. Furthermore, quantum algorithms can be used to analyze quantum states instead of classical data. Beyond quantum computing, the term "quantum machine learning" is often associated with classical machine learning methods applied to data generated from quantum experiments, such as learning quantum phase transitions or creating new quantum experiments. Quantum machine learning also extends to a branch of research that explores methodological and structural similarities between certain physical systems and learning systems, in particular neural networks. For example, some mathematical and numerical techniques from quantum physics are applicable to classical deep learning and vice versa. Finally, researchers investigate more abstract notions of learning theory with respect to quantum information, sometimes referred to as "quantum learning theory".
Patrick Gill, is a Senior NPL Fellow in Time & Frequency at the National Physical Laboratory (NPL) in the UK.
Applying classical methods of machine learning to the study of quantum systems is the focus of an emergent area of physics research. A basic example of this is quantum state tomography, where a quantum state is learned from measurement. Other examples include learning Hamiltonians, learning quantum phase transitions, and automatically generating new quantum experiments. Classical machine learning is effective at processing large amounts of experimental or calculated data in order to characterize an unknown quantum system, making its application useful in contexts including quantum information theory, quantum technologies development, and computational materials design. In this context, it can be used for example as a tool to interpolate pre-calculated interatomic potentials or directly solving the Schrödinger equation with a variational method.
