ORLANDO, Fla., Jan. 30, 2019 /PRNewswire/ -- The Javelin Joint Venture was awarded a production contract for 2,100 F-Model (FGM-148F) missiles, following a successful and rigorous system qualification test program that included 21 successful flight tests. The contract launches the initial full-rate production agreement for the Javelin F-Model missile, replacing the Javelin FGM-148E (Block I). The Javelin FGM-148F missile features an advanced multipurpose warhead (MPWH) as part of the man portable, fire-and-forget Javelin missile system. The MPWH incorporates the latest generation shaped charged technology to defeat present and future advanced armored threats while adding a fragmenting steel warhead case to significantly improve lethality against soft targets and light armored vehicles. The Javelin F-Model round deliveries are planned for early 2020 and will be available for international allies, with U.S. government permission. There are also funded efforts underway to develop a higher performance Lightweight Command Launch Unit (CLU) and FGM-148G Model missile that will dramatically improve system performance while reducing weight and lowering system cost. First deployed in 1996, Javelin is the world's most versatile and lethal one-man-portable and platform-employed anti-tank and multi-target precision weapon system. To date, more than 45,000 missiles and 12,000 CLUs have been produced. The Javelin weapon system has experienced numerous technology insertions since its initial fielding to stay ahead of advancing threats. Javelin, which is produced by a joint venture between Raytheon and Lockheed Martin, has been used extensively and to great advantage in combat operations in both Afghanistan and Iraq. Over 5,000 engagements have been successfully conducted by U.S. and coalition forces. Current U.S. allies that have Javelin in inventory include France, Taiwan, Jordan, Qatar, Turkey, Lithuania, Czech Republic, Indonesia, Ireland, New Zealand, Norway, Oman, Ukraine, Georgia, Australia, Estonia, UAE and the United Kingdom. The Javelin Joint Venture is an award-winning enterprise recognized in 2015 by the Office of the Secretary of Defense for its outstanding achievements in providing operational support to warfighters with the highest level of mission success and tactical operational readiness. About Lockheed Martin Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company that employs approximately 105,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services.

Nine teams hailing from four continents gathered in Idaho Springs, Colorado, the week of April 5-11, 2019, to test autonomous air and ground systems for navigating the dark, dangerous, dirty, and unpredictable underground domain. The SubT Integration Exercise, known as STIX, took place at the Colorado School of Mines' Edgar Experimental Mine. The event provided a shakeout opportunity for competitors in advance of the Tunnel Circuit in August, the first of three subdomains that teams will tackle in DARPA's Subterranean Challenge. The teams were divided into three groups. Each group had one day to experiment with their various systems during multiple runs in the mine, followed by a second day in which each team attempted a one-hour mock, scored run. Teams could earn points by accurately locating, identifying, and reporting artifacts placed within the tunnels. Artifacts included thermal manikins, backpacks, fire extinguishers, cell phones, and cordless drills – all inspired by objects an end user such as a warfighter or first responder might encounter. The mine environment presented teams with low light, high dust, metal rails, and irregular terrain. The DARPA team added to the complexity with a theatrical smoke machine, which mimicked real smoke a warfighter or first responder could contend with in an emergency response scenario, for example. “It was amazing to see the progression from day one into day two for each team as they explored the tunnels of the mine and began to understand just how complex and unknown these underground environments can be,” said Timothy Chung, program manager for the Subterranean Challenge in DARPA's Tactical Technology Office. “It's not just about testing whether there's enough light or if robots can drive a few meters. It's about how all that has to come together in a difficult environment and the teams are experiencing the challenge of integration in addition to technology development.” The competitors at STIX included a mix of DARPA-funded and self-funded teams: CERBERUS University of Nevada, Reno ETH Zurich, Switzerland Sierra Nevada Corporation University of California, Berkeley Flyability, Switzerland CoStar: Collaborative SubTerranean Autonomous Resilient Robots Jet Propulsion Laboratory California Institute of Technology Massachusetts Institute of Technology KAIST, South Korea CRETISE: Collaborative Robot Exploration and Teaming In Subterranean Environments Endeavor Robotics Neya Systems CSIRO Data 61 Commonwealth Scientific and Industrial Research Organisation, Australia Emesent, Australia Georgia Institute of Technology CTU-CRAS Czech Technical University in Prague, Czech Republic Université Laval, Canada Explorer Carnegie Mellon University Oregon State University MARBLE: Multi-agent Autonomy with Radar-Based Localization for Exploration University of Colorado, Boulder University of Colorado, Denver Scientific Systems Company, Inc. PLUTO: Pennsylvania Laboratory for Underground Tunnel Operations University of Pennsylvania Exyn Technologies Ghost Robotics Robotika Robotika.cz, Czech Republic Czech University of Life Science, Czech Republic Following the Tunnel Circuit, teams will compete in the Urban Circuit, which will focus on underground urban environments such as mass transit and municipal infrastructure; and the Cave Circuit, which will focus on naturally occurring cave networks. Locations for the circuit events have not been announced. Qualification is ongoing for the circuit events. Requirements can be found in the SubT Qualification Guide available on the Resources Page. Teams interested in joining either the virtual or systems tracks can still register and are encouraged to join the SubT Community Forum to exchange ideas, explore teaming opportunities, and receive updates on the Challenge.
