Companies continue to experiment with and develop new technologies to meet global needs. With the emphasis on international security and environmental issues, many businesses and governments have implemented new aerospace and defense equipment to address these concerns. Faster, lighter, safer, and more fuel efficient are important watchwords in the aerospace and defense industries. Using these innovations, both military and civilian aircraft have been redesigned and equipped with additional on-board technology.
Very light jets (VLJs)Very light jets (VLJs) are also sometimes referred to as microjets. These are single-pilot planes, weighing less than 10,000 pounds, that carry four to eight passengers and sometimes function as air taxis.
PurePower enginesPurePower engines developed from the geared turbofan (GTF) engines, which followed advanced technology fan integrators (ATFIs). Touted to decrease fuel use by 10% to 15%, PurePower engines are ideal for military planes because the engine noise level is significantly reduced.
Military airlift marketMilitary airlift comprises both fixed-wing and rotary airlift applications. With ongoing wars and terrorism affecting many nations, military airlift is central to the defense strategies of many countries around the world.
Unmanned aerial vehicle (UAV)Also called an unmanned aircraft vehicle system (UAVS) or unmanned aircraft system (UAS), an unmanned aerial vehicle (UAV) is an aircraft without a pilot. Some follow preprogrammed flight plans, whereas others fly by remote control. UAVs are generally flown for military reconnaissance and attack, but civilian uses include firefighting or other missions too dangerous for humans.
Pulse detonation engine (PDE)The pulse detonation engine (PDE), or the pulse detonation wave engine (PDWE), detonates rather than burns its fuel. This gives the engine the capacity to operate under different flight conditions with increased performance.

Synthetic aperture radar (SAR)Most radar uses a large, rotating antenna, but the Synthetic-aperture radar (SAR) has many small, scattered, stationary antennas. By using many small antennas and combining all the signals, the SAR gets a more complete picture; however, it needs a significant amount of computer resources to process all the data. Often SARs are attached to aircraft to conduct remote sensing and mapping.
