The
global aerial technological changes taking place are partially being led by the
aerospace industry. Technological up gradations are being incorporated in civil
and military sector operations. The defense sector is not far behind as there
are increasing technological changes that are taking place in this respect and
many countries are investing in the aerospace discipline to further improve
their defense sector.
Aerospace
technology is helping the defense sector to deal with one of the most obvious
challenges of operation. Proper surveillance is a must for efficient and
successful missions. Swedish Saab has recently completed the first flight of
its Global Eye Airborne Early Warning and Control aircraft, which it claims is
among the most advanced swing role surveillance systems in the world. Global
Eye brings together a sophisticated set of the latest surveillance sensors and
communications that allow the operators to survey air.
The
large radar on the back of the aircraft is an Erieye ER active electronically
scanned array (AESA) consisting of numerous advanced modules that use gallium
nitride technology (GaN) technology to scan air and surfaces for the most
challenging of targets within a very large volume of space. Seaspray radar by
Leonardo is located underneath the aircraft and supports on surface
surveillance, while an electro-optical turret near the front bottom region
provides round the clock imaging within a 360 degree arc.
The
data from these various sensors is provided to an operator who can further
direct these sensors. The network nature of Global Eye means that it can share
this information with others, issue instructions or accept data or communications
from third parties.
Aerospace
technology is not only inventing new machines but also upgrading existing ones.
The Lockheed Martin/Boeing F-22 Raptor is undergoing rapid developments.
Recently it was fitted with better signal reception and transmission systems
and subsequent blocking mechanisms that will enhance its ability to combat
other aircrafts. It has also received improved sensors and apart from this the
upgrade planned for 2018 will include a new storage and management system for
advanced missiles like AIM-9X Sidewinder and AIM-120D AMRAAM over which the
operators will have improved control.
Chinese
armed forces are also incorporating technology in their products and are
developing their own hi-tech aircrafts. The new fourth generation Chengdu J-20
is the first multi-role stealth fighter in China’s armed forces. Capable of
air-to-air and air-to-ground combat, it carries more fuel and weapons than the
F-22 Raptor and features fifth generation subsystems and field signature
reduction technology.
Russian
companies are also developing programs to promote aerospace developments in
their air force. The Sukhoi Su-57 is a product of the Russian Air Force’s PAK
FA fifth generation fighter programme and will succeed the MIG-29 and Su-27.
The Sukhoi Su-57 is believed to have super cruise, stealth, super
maneuverability and advanced avionics along with the capacity for extensive
loads of ordnance.
According
to the study, ‘Aerospace
& Defense Global Industry Almanac 2017-2021’, many more
developments are taking place across the world mostly being carried out by the
US. Its current surveillance and patrol technology is being improved by taking
ISR (intelligence, surveillance and reconnaissance) to the next level. Stealth
bombing is also an upcoming sector with the American B-21 Raider being one of
the latest developments.
The
country is also investing heavily in aerial refueling for its military
aircraft, for which the US Air Force is replacing its older jets with the
Boeing KC-46 Pegasus which is among the most advanced military aerial refueling
and strategic transport aircrafts in operation.
Aerospace
defense technology can safely be considered among the growth drivers for the
aerospace industry. Many countries are transforming their military using
aerospace as a potential tool. Multiple military products are exemplifying not
only the extent to which innovation can lead the military sector, but also the
productiveness that can be extracted from such developments. The US has
undoubtedly emerged as the global leader in aerospace defense technology with
many current projects still under development whilst facing competition from
China and Russia.
