Fifth generation jet fighter
Encyclopedia
A fifth-generation jet fighter is a fighter aircraft
classification used in the United States encompassing the most advanced generation of fighter aircraft. Fifth-generation aircraft are the most advanced , designed to incorporate numerous technological advancements over the class similarly dubbed fourth generation, including all-aspect stealth
even when armed, Low Probability of Intercept Radar (LPIR), high-performance air frames, advanced avionics
features, and highly integrated computer systems capable of networking with other elements within the theater of war to achieve an advantage in situational awareness. The only currently combat-ready fifth-generation fighter, the Lockheed Martin F-22 Raptor, entered service with the U.S. Air Force in 2005; the Lockheed Martin F-35 Lightning II is in development. Fifth-generation aircraft are exceptionally expensive, and have been difficult to justify in the post-Cold War
period.
and F-117 Nighthawk
, lacked LPI Active Electronically Scanned Array
(AESA) radars, and LPI radio networks, and were thus limited to attacking ground targets, because use of radar
to engage other aircraft would have revealed the aircraft's position.
In the early 1970s, various American design projects identified stealth, speed, and maneuverability as key characteristics for a next generation air to air combat aircraft. This led to the Request for Information
for the Advanced Tactical Fighter
project in May 1981 which would lead to the F-22.
Then in the late 1980s, the Soviet Union
outlined a need for a next-generation aircraft to replace 4th generation fighter aircraft: MiG-29 Fulcrum
and Su-27 Flanker
in frontline
service. Two projects were proposed to meet this need, the 4.5th generation fighter aircraft: Su-47 Berkut
and the MiG-1.44 Flatpack
(although later modernized MiG-35
to 4.5th generation fighter). In 2002, Sukhoi
was chosen to lead the design for the new combat aircraft.
The fifth-generation fighter aircraft, Sukhoi PAK FA (T-50)
will incorporate technology from both the Su-47 and the MiG 1.44 and when fully developed is intended to replace the MiG-29 and Su-27 in the Russian inventory and serve as the basis of the Sukhoi/HAL FGFA
project being developed with India
. A fifth-generation jet fighter, it is designed to fight against the American F-22 Raptor and F-35 Lightning II
. The Sukhoi PAK FA performed its first flight 29 January 2010. Russia is now constructing a new stealth lightweight multirole fighter
- MiG-LMFS (aka Projekt 1.27, MiG-1.27)
by Mikoyan
aircraft manufacturer. This jet fighter is based on the cancelled MiG 1.44. Russia will also provide India
with an advanced version of the Sukhoi-30MKI, which will have fifth generation capabilities and stealth features. India will be giving 18 Sukhoi-30K aircraft to Russia, to replace them with the advanced Sukhoi-30MKI, which is being christened as "Super Sukhoi" that boasts of fifth generation features.
India is also developing Medium Combat Aircraft
, a twin-engine fifth-generation stealth multirole fighter apart from Sukhoi/HAL FGFA
project being developed with Russia. The main purpose of this aircraft is to replace the aging SEPECAT Jaguar
& Dassault Mirage 2000. Unofficial design work on the MCA has been started.
By late 1990s, several Chinese fifth-generation fighter programs, grouped under the program codename J-XX or XXJ, were identified by western intelligence sources. PLAAF officials have confirmed the existence of such a program, which they estimate will enter service between 2017-2019. Nevertheless, the United States has predicted that it may possess as much as 20 times more "advanced stealth fighters" than the Chinese by 2020. By late 2010, it had emerged that two prototypes (#2001 & 2002) of the Chengdu J-20
had been constructed and were undergoing high-speed taxi trials. The J-20 made its first flight on 11 January 2011.
In July 2010, news emerged that Pakistan
will upgrade its inventory of CAC/PAC JF-17 Thunder planes with the help of its close ally, China
. 250 JF-17s will be built for the Pakistan Air Force
by 2025, some of which will be configured as "stealthy 5th generation" fighters. It was reported that an MoU
had been signed to develop a stealthy variant and, of the 250 fighters to be produced for Pakistan, 100–150 stealthy versions may be produced between 2015 and 2025.
South Korea has its own project to build a fifth-generation fighter, called KAI KF-X, while Japan also has project Mitsubishi ATD-X
.
The only fifth-generation jet fighter currently in operational service is the F-22 Raptor. US fighter manufacturer Lockheed Martin
uses "fifth generation fighter" to describe the F-22 and F-35 fighters, with the definition including "advanced stealth", "extreme performance", "information fusion" and "advanced sustainment". Their definition does not include supercruise
capability, which has typically been associated with the more advanced modern fighters, but which the F-35 lacks. Lockheed Martin attempted to trademark the term "5th generation fighters" in association with jet aircraft and structural parts thereof, and has a trademark to a logo with the term.
United States military officials have said that Russia and China are far from matching the F-35 and by the time they do, the United States will have moved on to the next level, sixth generation jet fighter
.
, though the Sukhoi PAK FA T-50 has engine intake extensions that seem to function somewhat like canards and the Chengdu J-20 designers have chosen the agility enhancements of canards in spite of their poor stealth characteristics. They all have twin canted vertical tails also to minimize side RCS. Most fifth-generation fighters with supermaneuverability
achieve it through thrust vectoring
.
They all have internal weapon bays in order to avoid high RCS weapon pylons, but they all have external hardpoint
s on their wings for use on non-stealthy missions, such as the external fuel tanks the F-22 carries when deploying to a new theater.
All fifth-generation fighters have a high percentage of composite material
s, in order to reduce RCS and weight.
Fifth generation jet fighters need stealthy augmentor for the afterburners of their jet engines such as those found on the Pratt & Whitney F135
or Pratt & Whitney F119
in order to have a stealthy supersonic aircraft as afterburner is required to enter into supercruise flight.
All revealed fifth-generation fighters use commercial off-the-shelf
main processors to directly control all sensors to form a consolidated view of the battlespace with both onboard and networked sensors, while previous generation jet fighters used federated systems where each sensor or pod would present its own readings for the pilot to combine in her own mind a view of the battlespace. This means that while the F-22A was physically delivered without synthetic aperture radar
or situational awareness infra-red search and track
it will gain these functions later through software upgrades. However any flaw in these huge software systems can knock out supposedly unrelated aircraft systems and the complexity of a software defined aircraft can lead to a software crisis

is fully developed. The engines for the F-35 are still under development, the Chinese are dependent on Russian engines, and even the Russians are falling short in the development of the latest jet engines.
, former Secretary of the United States Air Force, has suggested elimination of the Boeing E-3 Sentry and Boeing E-8 Joint STARS in favor of more F-35s, simply because so much effort is being made by the Russians and Chinese to target these platforms that are built to commercial airliner standards.
However, the more powerful sensors, such as AESA radar which is able to operate in multiple modes at the same time, may present too much information for the single pilot in the F-22, F-35 and T-50 to adequately use. The Sukhoi/HAL FGFA
offers a return to the two-seat configuration common in fourth generation strike fighters.
and Eurofighter as well as by other commentators, such as Bill Sweetman
: "...it is misleading to portray the F-22 and F-35 as a linear evolution in fighter design. Rather, they are a closely related pair of outliers, relying on a higher level of stealth as a key element of survivability - as the Lockheed YF-12
and Mikoyan MIG-25, in the 1960s, relied on speed and altitude."
The United States Navy and Boeing have placed the Boeing F/A-18E/F Super Hornet in a "next generation" fighter category along with the F-22 and F-35, as the Super Hornet has a "fifth generation" AESA radar, modest radar cross-section (RCS) reductions and sensor fusion. A senior USAF pilot has complained about fifth-generation claims for the Super Hornet: "The whole point to fifth generation is the synergy of stealth, fusion and complete situational awareness. The point about fifth-generation aircraft is that they can do their mission anywhere - even in sophisticated integrated air defense [IADS] environments. If you fly into heavy IADS with a great radar and sensor fusion, but no stealth, you will have complete situational awareness of the guy that kills you." Michael “Ponch” Garcia of Raytheon
has said that the addition of their AESA radars to the Super Hornet provides "90 percent of your fifth-generation capability at half the cost."
In response to the use of the "fifth generation" term, Eurofighter has made a fifth-generation checklist placing different weights on the various capabilities, and arguing that the application of the label to strike aircraft such as Lockheed-Martin's F-35 is ill advised, and even inconsistent with the aircraft's specifications. Meanwhile, Eurofighter adds 'net-enabled operations' as noteworthy requirement and deemphasizes full-scope low observability as only one factor in survivability. In the same article Eurofighter GmbH appear to acknowledge the remarkable performance of Lockheed Martin's F-22 aircraft, while demonstrating that labels as simple as "fifth generation" may easily be devised to serve the interests of the writer.
Richard A. Bitzinger of the S. Rajaratnam School of International Studies, a former consultant for the American RAND
think tank suggests that Western Europe's "failure" to develop a fifth generation jet fighter may reduce these former leaders in the market to also ran status in the future as the world's attention shifts to the competition between the United States and Asian powers. Canadians Alex Wilner and Marco Wyss of the Center for Security Studies claim that Europe's failure to "keep up" with the F-35 may make the European jet fighter manufacturers close up shop.

If you fly into heavy IADS with a great radar and sensor fusion, but no stealth, you will have complete situational awareness of the guy that kills you." Michael “Ponch” Garcia of Raytheon

has said that the addition of their AESA radars to the Super Hornet provides "90 percent of your fifth-generation capability at half the cost."
In response to the use of the "fifth generation" term, Eurofighter has made a fifth-generation checklist placing different weights on the various capabilities, and arguing that the application of the label to strike aircraft such as Lockheed-Martin's F-35 is ill advised, and even inconsistent with the aircraft's specifications. Meanwhile, Eurofighter adds 'net-enabled operations' as noteworthy requirement and deemphasizes full-scope low observability as only one factor in survivability. In the same article Eurofighter GmbH appear to acknowledge the remarkable performance of Lockheed Martin's F-22 aircraft, while demonstrating that labels as simple as "fifth generation" may easily be devised to serve the interests of the writer.

think tank suggests that Western Europe's "failure" to develop a fifth generation jet fighter may reduce these former leaders in the market to also ran status in the future as the world's attention shifts to the competition between the United States and Asian powers. Canadians Alex Wilner and Marco Wyss of the Center for Security Studies claim that Europe's failure to "keep up" with the F-35 may make the European jet fighter manufacturers close up shop.
