Document 3: Northrop Grumman E-2 Hawkeye: The Northrop Grumman E-2 Hawkeye is an American all-weather, carrier-capable tactical airborne early warning (AEW) aircraft. This twin-turboprop aircraft was designed and developed during the late 1950s and early 1960s by the Grumman Aircraft Company for the United States Navy as a replacement for the earlier, piston-engined E-1 Tracer, which was rapidly becoming obsolete. The aircraft's performance has been upgraded with the E-2B, and E-2C versions, where most of the changes were made to the radar and radio communications due to advances in electronic integrated circuits and other electronics. The fourth major version of the Hawkeye is the E-2D, which first flew in 2007. The E-2 was the first aircraft designed specifically for its role, as opposed to a modification of an existing airframe, such as the Boeing E-3 Sentry. Variants of the Hawkeye have been in continuous production since 1960, giving it the longest production run of any carrier-based aircraft.

Document 6: ASR-9: ASR-9 is an airport surveillance radar system admitted into the National Airspace System (NAS), to be utilized by the Federal Aviation Administration to monitor civilian and commercial air traffic within the United States. Developed by Westinghouse, ASR-9 was the first radar system to display air traffic, and weather conditions simultaneously. The ASR-9 is mainly intended to monitor and track aircraft below 25,000 ft and within forty to sixty nautical miles from the airport of operation. The ASR radar systems were widely used where an advanced radar system was needed, consisting of 135 different ASR-9 operating locations around the U.S. The FAA is currently working to upgrade the remaining ASR-9 radar sites to a modernized digital version known as the ASR-11.
Document 7: AN/APQ-159: Emerson Electric's AN/APQ-159 was an I band/J band radar designed to upgrade Emerson's simple AN/APQ-153 used in the Northrop F-5. It offered roughly double the range, increased off-boresight tracking angles, and considerably improved reliability. Originally intended to be replaced by the further improved AN/APQ-167, modernized F-5s have typically moved to the entirely new AN/APG-69 instead.
Document 8: AN/APQ-153: Emerson Electric's AN/APQ-153 was an I band radar system developed for the Northrop F-5E fighter aircraft. Required to fit into the tight confines of the originally radar-less F-5, the system offered relatively simple air-to-air modes and a short detection range. The AN/APQ-157 was a similar system with dual displays and controls for the twin-seat F-5F trainer. Many of the F-5's still flying have been upgraded to the improved AN/APQ-159.
Document 9: GE Appliances: GE Appliances, formerly known as GE Appliances & Lighting and GE Consumer & Industrial, along with GE Appliances, when owned by General Electric (GE), is an appliance company headquartered in Louisville, Kentucky and owned by Haier Group. It is one of the largest appliance brands in the United States. The company encompasses the appliance brands of GE, Profile, Cafe, Monogram, and Hotpoint. GE Appliances includes wholly owned subsidiary FirstBuild, a global co-creation community and state-of-the-art microfactory located in Louisville, Kentucky.
Document 10: KAB-1500L: KAB-1500L is a Russian precision guided weapon, a laser guided bomb and also the current production standard for use on 4+ and 4++ generation fighter jets, like the Sukhoi Su-30MKI/Sukhoi Su-30MKK, Sukhoi Su-34 and Sukhoi Su-35. It is claimed to be the Russian equivalent to USA's Paveway II/Paveway III and is designed to hit railway, ammunition depots, railway terminals, highway bridges, military and industrial facilities, ships and transport vessels. The KAB-1500LG-F-E has an impact fuse which includes 3 different delay modes for target attack and it can also be mounted on older aircraft, like the Sukhoi Su-24 and the Mikoyan MiG-27.
Document 11: KEMET Corporation: KEMET Corporation was set up in 1919 and now is based in Simpsonville, South Carolina. The company produces many kinds of capacitors, such as tantalum, aluminum, multilayer ceramic, film, paper, polymer electrolytic, and supercapacitors. Capacitors are electronic components that store, filter, and regulate electrical energy and current flow. As an essential passive component used in most circuit boards, capacitors are typically used for coupling, decoupling, filtering, oscillating and wave shaping and are used in communication systems, data processing equipment, personal computers, cellular phones, automotive electronic systems, defense and aerospace systems, consumer electronics, power management systems and many other electronic devices and systems (basically anything that plugs in or has a battery). The company also manufacturers a variety of electronic components such as, AC line filters, EMI cores and filters, flex suppressors, relays, metal composite inductors, ferrite products, and transformers/magnetics. The product line consists of nearly 5 million distinct part configurations distinguished by various attributes, such as dielectric (or insulating) material, configuration, encapsulation, capacitance (at various tolerances), voltage, performance characteristics and packaging.

Document 14: Northrop F-15 Reporter: The Northrop F-15 Reporter (later RF-61) was an American unarmed photographic reconnaissance aircraft. Based on the Northrop P-61 Black Widow night fighter, it was the last piston-powered photo-reconnaissance aircraft designed and produced for the United States Air Force. Though produced in limited quantities, and with a relatively short service life, the F-15's aerial photographs of the Korean Peninsula would prove vital in 1950, when North Korea invaded the south.
Document 15: AN/APQ-181: The AN/APQ-181 is an all-weather, low probability of intercept (LPI) radar system designed by Hughes Aircraft (now Raytheon) for the U.S. Air Force B-2A Spirit bomber aircraft. The system was developed in the mid-1980s and entered service in 1993. The APQ-181 provides a number of precision targeting modes, and also supports terrain-following radar and terrain avoidance. The radar operates in the K band (a subset of the J band). The original design uses a TWT-based transmitter with a 2-dimensional passive electronically scanned array (PESA) antenna.
