The Johns Hopkins University Applied Physics Laboratory, commonly known as simply the Applied Physics Laboratory, or APL, located in Howard County, Maryland, near Laurel and Columbia, is a not-for-profit, university-affiliated research center (or UARC) employing over 6,000 people. The Lab serves as a technical resource for the Department of Defense, NASA, and other government agencies. APL has developed numerous systems and technologies in the areas of air and missile defense, surface and undersea naval warfare, computer security, and space science and spacecraft construction.[2] While APL provides research and engineering services to the government, it is not a traditional defense contractor, as it is a UARC and a division of Johns Hopkins University. APL is a scientific and engineering research and development division, rather than an academic division, of Johns Hopkins.
Hopkins' Whiting School of Engineering offers part-time graduate programs through its Engineering for Professionals program. Courses are taught at seven locations in the Baltimore-Washington Metropolitan Area, including the APL Education Center.[3]

History
APL was created in 1942 during World War II under the Office of Scientific Research and Development as part of the Government's effort to mobilize the nation's science and engineering expertise within its universities. Its founding director was Merle Anthony Tuve. The Laboratory succeeded in developing the variable-time proximity fuze[4] that played a significant role in the Allied victory.[5] In response to the fuze's success, the APL created the MK 57 gun director in 1944. Pleased with the APL's work, the Navy then tasked it with the mission to find a way to negate guided missile threats. From there on, the APL became very involved in wartime research.[6] Expected to disband at the end of the war, APL instead became heavily involved in the development of guided missile technology for the Navy. At governmental request, the University continued to maintain the Laboratory as a public service.
APL was originally located in Silver Spring, Maryland in a used-car garage[7] at the former Wolf Motor Company building at 8621 Georgia Avenue.[8] APL moved to Laurel beginning in 1954, with the construction of a two million dollar building and a $700,000 wing expansion in 1956.[9] The final staff transitioned to the new facility in 1975.[7][10] Before moving to Laurel, APL also maintained the "Forest Grove Station", north of Silver Spring on Georgia Avenue near today's Forest Glen Metro,[11] which included a hypersonic wind tunnel. The Forest Grove Station was vacated and torn down in 1963 and flight simulations were moved to Laurel.
The Laboratory's name comes from its origins in World War II, but APL's major strengths are systems engineering and technology application. More than three quarters of the staff are technical professionals, and 25% have computer science and math degrees. APL conducts programs in fundamental and applied research; exploratory and advanced development; test and evaluation; and systems engineering and integration.
Wartime Contributions
During the 1950s and the 1960s APL worked with the US Navy in the Operation Bumblebee Program on the Talos missile, Tartar missile, Terrier, and RIM-2 Terrier Surface to Air Missile systems. The follow-on RIM-50 Typhon Missile Project, based on improved Talos and Tartar Missiles, while successful, was cancelled in 1963 due to high costs and was eventually developed into the now well known AEGIS system based on an improved Terrier. In 1965, the US Army contracted with APL to develop and implement a test and evaluation program for the Pershing missile systems.[12] APL developed the Pershing Operational Test Program (OTP), provided technical support to the Pershing Operational Test Unit (POTU), identified problem areas and improved the performance and survivability of the Pershing systems.[13]
In 1990, APL became involved with Operation Desert Storm and was involved in the Gulf Crisis Room[clarification needed] among other efforts. In the same decade (1992), APL, along with Johns Hopkins University, developed an algorithm that allowed for automatic mammogram analysis.[6]
Campus
The modern Applied Physics Laboratory is located in Laurel, Maryland, and spans 453 acres with more than 20 buildings on site. Additional auxiliary campuses exist in the surrounding areas.[14]
Education
APL is also home to a Johns Hopkins graduate program in engineering and applied sciences, called Engineering for Professionals.[15] Courses are taught at seven locations in the Baltimore-Washington Metropolitan Area, including the APL Education Center.[3]
Research
As of APL's 70th anniversary in 2012, there were over 600 projects in progress, spanning from those in APL's more traditional areas of work, including air defense, undersea warfare precision engagement and strategic systems to newer types of projects, including those in homeland security and cyber operations.[6] Due to the nature of the APL's work, many of its projects' details are kept confidential.
Defense
The U.S. Navy continues to be APL's primary long-term sponsor. The Laboratory performs work for the Missile Defense Agency, the Department of Homeland Security, intelligence agencies, the Defense Advanced Research Projects Agency (DARPA), and others. The Laboratory supports NASA through space science, spacecraft design and fabrication, and mission operations. APL has made significant contributions in the areas of air defense, strike and power projection, submarine security, antisubmarine warfare, strategic systems evaluation, command and control, distributed information and display systems, sensors, information processing and space systems.
Space
APL has built and operated many spacecraft, including: the TRANSIT navigation system, NEAR, Geosat, ACE, TIMED, CONTOUR, MESSENGER, Van Allen Probes,[16] the New Horizons mission to Pluto, and STEREO.[16] APL proposed the Titan Mare Explorer (TiME) mission to NASA.[16] The asteroid 132524 APL was named in honor of APL after a flyby by the New Horizons spacecraft. The Lab is currently developing the Parker Solar Probe mission to probe the outer corona of the Sun.[17] In 2017, APL proposed Titan Dragonfly to NASA: Dragonfly is a lander, using rotors in a dual-quadcopter configuration to change its location on Saturn's moon, Titan (moon).
Prosthetics
In 2014, APL made history with the successful use of the Modular Prosthetic Limb — a fully artificial articulated arm and hand — by a bilateral shoulder-level amputee. APL used pattern recognition algorithms to track which muscles were contracting and enable the prosthetics to move in conjunction with the amputee's body.[18]
Similar technology was used in 2016 for a demonstration in which a paralyzed man was able to "fist-bump" Barack Obama using signals sent from an implanted brain chip.[19] The limb returned sensory feedback from the arm to the wearer's brain.
Drones
The APL researches and produces unmanned aerial vehicles for the US military.[20] One of its most recent projects is an unmanned aerial swarm that can be controlled by a single operator on the ground.[21]

Aerospace Manufacturing and Design.Boeing and the Johns Hopkins University Applied Physics Laboratory (JHU/APL) have demonstrated that an operator on the ground, using only a laptop and a military radio, can command an unmanned aerial vehicle (UAV) "swarm." Despite limited flight training, the operator was able to connect with autonomous UAVs, task them and obtain information without using a ground control station. [...] The demonstrations are conducted under a collaborative agreement between Boeing and JHU/APL, a University Affiliated Research Center and a division of Johns Hopkins University that has been addressing critical national challenges through the innovative application of science and technology for nearly 70 years. It maintains a staff of about 5,000 on its Laurel, MD, campus.
