回顾 2016 年军工行业业绩，军工行业上市公司业绩保持整体稳定状态，2017 年一季度部分上市公司业绩有所改善，但军工年底交货特点，一季度业绩释放空间有限。今年军工行业处在混改等改革和军机批产等中长期拐点利好兑现期，行业正全面向好。二季度在市场风险偏好变化等情况下，市场忽视军工行业基本面向好的变化，军工板块上市公司股价大幅回撤，板块整体被错杀，投资价值被低估。 

行业维持高景气度，预计未来3年行业净利润年均增速将维持20%左右；军工指数大幅回调，回到2014年11月的水平，即牛市启动初期的水平；我们研判军工板块：2017年下半年将以震荡态势为主。

In this report, Technavio covers the present scenario (with the base year being 2016) and the growth prospects of the global unmanned aerial vehicle (UAV) payload and subsystems market for 2017-2021. To calculate the market size, the report considers the revenue generated in the overall defense market from the procurement of sensors and cameras, weaponry, radars and communication systems, and other types of UAV payload and subsystems (ground control stations [GCS] and onboard computers).However, both funded and unfunded R&D investments in the development of UAV prototypes and payload components were not considered when deriving the market size for the base and projected years.

韩新任总统文在寅本周表示：前任政府部署“萨德”的决定不符合民主程序，是一个错误的决定。 “萨德”入韩为朝鲜半岛局势带来“不必要的紧张”，韩国应暂停“萨德”部署，新政府应对“萨德”入韩问题重新进行审视，应学会对华盛顿政府说“不”。 

Aircraft batteries are used to start engines while initiating taxiing or the APU. The batteries are also used to power the airplane interiors and services (such as broadband and air conditioning). The major battery chemistries that are generally used as modern aircraft batteries are lithium-based (Li-ion and lithium iron phosphate), nickel-based (Ni-Cd or nickel metal hydride), and lead-acid. Lead-acid batteries are usually employed in light and general aviation aircraft. The nickel-based batteries dominate larger aircraft and helicopter applications, which are being replaced by the lithium-based batteries since the past decade.

Attack helicopters or gunships are designed to carry heavy armaments such as antitank guided missiles (ATGMs) like Hellfire, auto canons, unguided rockets, heavy machine guns, and air-to-air missiles. The air-to-air missiles carried by them are mostly deployed for self-defense purposes. In addition, attack helicopters attack enemy tanks, flanks, and rear, which provides strategic support and assistance to the ground forces to maneuver and engage with hostile forces. In recent years, the threats imposed on civilian life have increased rapidly, particularly due to the rise in terrorism and crossborder insurgent activities. Therefore, development and procurement of attack helicopters have been increased in recent years to have a highly efficient and effective aerial attack force.

Airport passenger screening systems are being used at the airport security checkpoints since decades. Earlier, most of the airport passenger screening process relied on hand-held metal detectors or walk-through metal detector for passengers and X-ray systems for carry-on items. However, the evolving security threats and the inability of metal detectors to detect non-metallic objects and explosives are nudging many airports to implement advanced imaging technologies and procedures to screen passengers for explosives and non-metallic weapons.

Line maintenance is a part of aircraft MRO, which refers to the works on discrepancies as per the requirements of the flight crew in order to ensure airworthy condition of the aircraft. These works are conducted before or in between flight operations on a regular basis. Line maintenance involves two components: labor and materials. Some of the line maintenance activities are A checks, weekly/overnight checks, daily checks, transit checks, and pre-flight checks.

The global baby stroller and pram market has been registering positive growth over the last few years and is shaping up to become one of the top competitive markets at a global level. With the rise in globalization, ample growth opportunities are being created in the market.

An aerostat uses gases lighter than air such as hydrogen, helium, as well as hot air, which helps the aerostat to generate airlift. Aerostats include powered airships and unpowered balloons that are tethered to the ground. These are generally used for intelligence, surveillance, and reconnaissance (ISR) purposes by the military forces and also for tourism and civilian observations. An aerostat surveillance system possesses the long-endurance capability, which is not feasible with a fixed-wing aircraft. The alternatives to aerostats (such as unmanned aerial vehicles (UAVs)) are battery dependent, which results in operational failures.
