Document 2: Surgically implanted explosive device: A surgically implanted improvised explosive device (SIIED) is an explosive device hidden inside the body of a person in order to commit a suicide attack. This type of terrorist weapon, more commonly known as Body Cavity Bomb (BCB), is only known to have been used once, in a failed assassination attempt.
Document 3: Head impact telemetry system: Head Impact Telemetry (HIT) System technology was developed by Simbex (Lebanon, NH) with support from the National Institutes of Health (NIH; R44HD40743 and R01HD048638) to measure and record "in vivo" head impact exposure (i.e. frequency, location, and kinematics of head impact). Since 2003, the core technology, which includes an array of non-orthogonal accelerometers, data acquisition, RF telemetry hardware, and post-processing software, has been used in a variety of sport and military applications to investigate the relationship between head kinematics and brain injury. This research has enabled and contributed to improved helmet design and testing methods, changes to sporting rules and regulations, and novel approaches to improve player safety. Additionally, HIT System technology is the essential feature of Riddell’s Sideline Response System (SRS) - a real-time monitoring tool used by American football teams to manage an athlete’s head impact exposure.

Document 6: Joint Improvised-Threat Defeat Organization: The Joint Improvised-Threat Defeat Organization (JIDO, pronounced like "JI-DOH") is a combat support organization of the U.S. Department of Defense (DoD) organization under the Defense Threat Reduction Agency (DTRA) that deals with improvised threats such as the improvised explosive device (IEDs). JIDO was born from the Joint IED Defeat Organization established in 2006, which focused on IEDs. JIDO's mission is to "enable Department of Defense actions to counter improvised threats with tactical responsiveness and anticipatory acquisition in support of combatant commanders' efforts to prepare for, and adapt to, battlefield surprise." This mission supports counter-terrorism, counter-insurgency and other related mission areas including Counter-IED.
Document 7: SpaceDev: SpaceDev, a part of the "Space Systems Business" of Sierra Nevada Corporation, is prominent for its spaceflight and microsatellite work. It designed and built components for the hybrid rocket motors for Paul Allen's Tier One suborbital SpaceShipOne space program operated by Scaled Composites. It is also developing micro- and nano-satellites, a small expendable launch vehicle, the SpaceDev Streaker, and has designed a piloted suborbital and orbital spaceship of its own, the SpaceDev Dream Chaser, in collaboration with NASA.
Document 8: Sierra Nevada Corporation: Sierra Nevada Corporation (SNC) is an American privately held electronic systems provider and systems integrator specializing in microsatellites, telemedicine, and commercial orbital transportation services. Sierra Nevada Corporation operates under the leadership of Chief Executive Officer, Fatih Ozmen and President, Eren Ozmen. The company contracts with the United States Armed Forces, NASA and private spaceflight companies. It is headquartered in Sparks, Nevada.
Document 9: Rocket Lab: Rocket Lab is a US aerospace corporation with a New Zealand subsidiary. Rocket Lab's mission is to develop lightweight, cost-effective commercial rocket launch services. The Electron Program was founded on the premise that small payloads such as CubeSats require dedicated small launch vehicles and flexibility not currently offered by traditional rocket systems. Electron, Rocket Lab's lightweight launch vehicle, is designed to service the small satellite market with dedicated, high-frequency launch opportunities. Electron is designed to deliver payloads of 150 kg to a 500 km Sun-synchronous orbit.
Document 10: Thor III: The THOR III is man-portable, counter-radio-controlled improvised explosive device (IED) jammer built by Sierra Nevada Corp and employed by the U.S. Army, U.S. Marine Corps, and partnered Afghan National Army soldiers in Afghanistan. Sierra Nevada received the initial contract in December 2007. This system uses three transceivers mounted on backpacks to jam radio-controlled IEDs; each of the three different transceivers jams a different frequency bandwidth (Low, Mid, and High).
Document 11: AN/SQQ-32 Mine-hunting sonar: The AN/SQQ-32 Minehunting Sonar Set (MSS) is a variable-depth mine-hunting sonar system originally developed by Raytheon and Thales Underwater Systems (formerly Thomson Marconi Sonar) for the United States Navy. It includes two separate active sonar systems to detect and classify mine-like objects on the surface, in the volume, or on the bottom of the sea. The sonar systems are packaged in a single towed body tethered to the ship through a cable providing power and data transmission, with the cable length variable via an electric winch. A hole in the ship extending from the Sonar Maintenance Room (SMR) to the hull allows movement of the towed body in different configurations for maintenance, stowage at sea, and minehunting operations. The towed body can be configured for minehunting by either locking to the bottom of the ship’s hull for shallow water operations, or by extending and retracting the tow cable to allow for variable depth sonar (VDS) operations. VDS operations are necessary in deep water due to refraction of the sonar from the various temperature layers present in the ocean; with the sonar positioned in the same thermal layer as the suspected mines the error induced by refraction is minimized. The detect and classify sonar subsystems are independently monitored and controlled by two operators at independent panels working together to find and characterize underwater objects as mine or non-mine like objects.
Document 12: Stratolaunch Systems: Stratolaunch Systems Corporation is a space transportation venture developing a new air launch to orbit system, with its corporate headquarters located in Seattle, Washington. The project was officially announced in December 2011 by Microsoft co-founder Paul G. Allen and Scaled Composites founder Burt Rutan, who had previously collaborated on the creation of SpaceShipOne.

Lockheed Martin is the contractor for the design, development and production of the GPS III Non-Flight Satellite Testbed (GNST) and the first eight GPS III satellites. The United States Air Force plans to purchase up to 32 GPS III satellites. GPS IIIA-1, the first satellite in the series, was projected to launch in 2014, but significant delays have pushed the initial launch to the spring of 2018.
Document 14: Space Island Group: Space Island Group (SIG) is a commercial organization based in West Covina, CA that is dedicated to the development of commerce, research, manufacturing and tourism in space. They plan to accomplish this by designing, building and operating commercial space transportation systems and destinations. Their flagship project is the Space Island Project. This will be a stand-alone commercial space infrastructure supporting manned business activities in Low Earth Orbit (LEO) 400 to 500 miles above earth. They plan to accomplish this through the use of technologies, vehicles and procedures developed by NASA and aerospace companies over the last 25 years.
Document 15: Shielder minelaying system: The Shielder minelaying system was used by the British Army to create anti-tank barriers quickly. The system was based on the American Alliant Techsystems Volcano mine system. It was ordered in 1995 and first deployed in 1999. The system consists of up to 40 dispensers, each containing 6 mines, mounted on the flat bed version of the Alvis Stormer tracked armoured fighting vehicle. The dispensers can launch mines to the sides and rear of the vehicle as it proceeds. Each mine has a programmable life, after which they self-destruct. A dispenser control unit provides fire signals, testing and arming of the self-destruct mechanism.
