The Russian Su-75 "Checkmate" - just another case of "Vapor Marketing" or does it live up to the hype?

According to Aviation Week and Space Technology - a leading American magazine, the Russian Sukhoi Su-75 Checkmate has made it to the list of top 10 achievements in military aviation in 2021. Reportedly, the Russian, single-engine, light tactical stealth aircraft, grabbed attention owing to its maiden flight as an “unmanned wingman” and the first aerial refuelling performed by an unmanned aerial vehicle.

Notorious for hyping their high-grade Russian military equipment in unconventional ways, officials from Russia’s Sukhoi Design Bureau offered bottles of a limited-edition Checkmate "perfume", at the company's unveiling of the aircraft at the Dubai Air Show in December 2021.

So, what really is the hype surrounding, what is touted to be Russia's multi-purpose, stealth fighter-bomber, about?

Fact vs fiction

Priced at less than half of Saab Gripen ($85 million) and substantially cheaper than the US F-35 ($115 million) French Dassault Rafale ($115 million), the Su-75 Checkmate is projected as a low-cost alternative to the Lockheed Martin F-35 Lightning II and Shenyang FC-31 aircraft of the same light to medium-weight category.

Russia is one of the few countries with full-cycle capacities for the production of advanced aircraft systems. The new product developed by UAC specialists should arouse genuine interest not only in our country, but also in other regions of the world, including our competitors abroadsaid a company spokesperson at the air show

Reportedly, the Obninsk Research and Production Enterprise “Technologiya”-part of Roste? State Corporation, came up with a solution that it states- improves the characteristics of cockpit glazing by 20%, including reducing the radar visibility of military aircraft.

Today, the samples produced with the upgraded equipment confirmed the pre-calculated characteristics during measurements and tests. The new technology will be used to create structural optics for advanced aviation systems. This will reduce the radar visibility of the aircraft and increase their combat capabilitiesVladimir Artyakov, First Deputy CEO of Rostec State Corporation

Why are countries shying away from considering the Su-75 Checkmate?

Russia has been struggling to manufacture jet engines following sanctions and export restrictions imposed ever since it annexed Crimea in 2014. The recent impositions sanctioned due to the Russian-Ukrainian aggression have only made it worse.

After its official debut at the end of last year, there are still many unanswered questions about the Checkmate:

Although touted to be a 5th-generation aircraft by the company, doubts are raised over its advanced avionics and effective stealth technologyProcurement of certain technologies critical for the mass production of its advanced combat sensors with microprocessor sub-systems has been trumped by western sanctionsThe overall success of the "Checkmate" program is questionable given the demand for high-performance medium-weight fighter-bombers is plummetingThe single-seat, twin-engine multirole fighter Sukhoi Su-57 is, reportedly, the Russian Armed Force’s first stealth aircraft, although most western experts opine that it is the least ‘stealthy’ of its fighter generation

The nature of warfare tactics deployed around the world is constantly evolving, with armed drones and ground combat vehicles, costing just a fraction of what these "stealth crafts" cost. Furthermore, countries with a tight budget may naturally give "Checkmate" a pass, regardless of the features it so proudly "claims".

Also to be noted is the fact that a close analysis of Russian media reveals releases made about the "Checkmate" don't make a mention of "stealth technology" anywhere, and that raises serious doubts about the claims of the "5th generation stealth" aircraft.

According to reports, considering all said and done, it may finally be down to a case of "vapour marketing" and the model just might not actually live up to the hype.

Global climatic changes and the need for sustainable travel have pushed the who's who of the aerospace industry in a mad race to invest heavily in fuel-efficient, sustainable technologies.

Representative | Azom.com

Aircraft and engines can now run on 50% SAF, while tests are being conducted to ensure they fly on 100% SAF in the days to come.

Hydrogen technology, as an efficient alternative to aviation fuel, seems to have gained pace, with many players betting big on its viability. Although it seems promising at the moment, some still see it as an unlikely solution for large-scale operations.

Are there even bolder, more innovative projects out there? Sure there is.

And that's where the Falcon Solar aircraft "flies" in.

Falcon Solar - the futuristic solar-powered aircraft

A flying craft that can drop fuel altogether, and therefore not require any refuelling stops while still being capable of top-level performance - sounds appealing?

TechnoidHost

That's exactly what engineers at the US-Spanish aerospace firm-Skydwelle, have been working on. Solar Impulse solar-powered aircrafts developed by the company, just about give us an insight into the world of possibilities that can be achieved with such concepts.

Laszlo Nemeth of Lasky Design wanted to carry forward this idea and for this, he turned to nature to shape this futuristic solar-powered aircraft-‘Falcon Solar’. Inspired by birds of prey, the streamlined concept features large wings that curve upwards and a pointed cockpit and tail.

Even nowadays, nature’s iteration of shapes can be a good inspiration for design and help development with almost perfectly harmonious proportions such as golden ratiosays the Hungarian industrial designer

The design features an advanced set of wings that goes beyond the accepted norms of aircraft design and curves upwards. According to Nemeth, the Falcon Solar airplane can fly with zero-emission thanks to its large wing area that’s equipped with solar panels. The array of solar panels spans across the whole length of the wings which should, theoretically, be able to produce enough energy from the sun when gliding over the clouds.

The design breaks with conventional aircraft design and uses the advantage of flying wings. The shape is unique in that the fuselage also generates significant lift while providing a surface for the solar panelsNemeth

Apparently, the wings that are curved upwards seem much larger compared to the streamlined body, with a sharp tip.

Upward-curving wings | Representative | TechnoidHost

Rudder and vertical stabilizers are an indispensable part of aircraft construction- they actuate the direction of the aircraft. As can be seen evidently, the Falcon Solar design is void of these essential surface components and that's what makes this design unique. Furthermore, from the looks of it, the cabin area also seems to be very compact.

Not many details are known about its specifications and how actually it would take to the skies. Though a concept for now, its unique shape and design could inspire many more innovative and sustainable aircraft models for commercial purposes in the not-so-distant future.

According to NASA’s aviation safety reporting system-a forum where aviation professionals can anonymously share near misses and safety tips, the number of reports addressing GPS signal loss or disruption for private and commercial aircraft has increased.

What is GPS and what is its significance?

The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radio navigation system owned by the US government and operated by the United States Space Force. It operates independently of any telephonic or Internet reception and provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.

Representative | Imperative MOOCS

The GPS is basically a civilian version of the global navigation satellite systems (GNSS)-first devised by the U.S. military in the 1960s. Most airplanes now carry Automatic Dependent Surveillance-Broadcast (ADS-B) transponders, which use GPS to calculate and broadcast their altitude, heading, and speed. Private pilots use digital charts on tablet computers, while GPS data underpins autopilot and flight-management computers.

Murfreesboro Aviation

The GPS service is controlled by the United States government, which can selectively deny access to the system or degrade the service at any time.

Hence, several countries are in the race of setting up their own dedicated global or regional satellite navigation systems:

The Russian Global Navigation Satellite System (GLONASS) was developed contemporaneously with GPS, although it suffered from incomplete coverage of the globe until the mid-2000s.China's Beidou satellite navigation system began global services in 2018 and finished its full deployment in 2020The European Union has its own Galileo Satellite Navigation SystemThe Indian Regional Navigation Satellite System (IRNSS), developed by India, with the operational name - "NavIC "

Mrunal

The Japanese have developed the Quasi-Zenith Satellite System (QZSS)-a GPS satellite-based augmentation system to enhance GPS's accuracy in Asia-Oceania, with satellite navigation independent of GPS and scheduled for 2023.

Can GPS be jammed?

Yes, and quite easily so. How?

Apparently, it is a relatively uncomplicated process that involves the production of an RF signal strong enough to drown out the transmissions from GPS satellites. The subject of a GPS jamming attack will be instantly aware that something is wrong, as the system will be unable to produce a geolocation result. 

Representative | The National Interest

The vast majority of incidents involving GPS-based navigation systems either experience a total loss of signal or, more alarmingly — incorrect aircraft position reporting.

Representative | Aviation Week

Reportedly, undisclosed Federal Aviation Administration (FAA) data for a few months in 2017 and 2018 point to hundreds of aircraft losing GPS reception in the vicinity of military tests. Air Traffic Control (ATC), search and rescue operations, the electric grid and mobile phone services are all vulnerable to GPS jamming fallout.

GPS Spoofing

Yet another, a more insidious form of attack - involves a deliberate mimicking of the form of transmissions from GPS satellites, tricking the receiver into believing that it has been sent information as expected.

Representative | Norton

To give a perspective, it involves location information being sent to the GPS receiver which is clearly false and may/may not be immediately clear to the user that they are being spoofed, but, it nonetheless stops them from using their GPS for its intended purpose. In other words, it is a more targeted form of jamming.

Jamming incidents

There have been over 90 ASRS (Aviation Safety Report System) reports detailing GPS interference in the United States, most of which were filed in 2019 and 2020.

Representative | Source

Loss of life can happen because air traffic control and a flight crew believe their equipment are working as intended, but are in fact leading them into the side of the mountain. Had we not noticed, that flight crew and the passengers would be dead. I have no doubt.said an air traffic controller referring to an aircraft incident in Idaho (August 2018) flying in smoky conditions and which apparently suffered GPS interference from military tests

Reportedly, the military is known to jam GPS signals to develop its defence (s) against GPS jamming.

Planned electronic-attack (EA) testing occasionally causes interference to GPS based flight operations, and impacts the efficiency and economy of some aviation operationsSaid a 2013 military report

Why would the military interfere with such a safety-critical system?

The GPS is exceedingly vulnerable to attack. these signals are diminished before they hit the ground. And quite surprisingly, building an electronic warfare system to disrupt these weak signals is apparently easy.

Detune the oscillator in a microwave oven and you've got a super powerful jammer that works over many kilometerssays Todd E Humprheys-director of the Radio navigation Laboratory at the University of Texas at Austin

In most of the cases reported, the loss of GPS was deemed an emergency. Pilots have veered off-course, accidentally entered military airspace, have been unable to manoeuvre, and lost their ability to navigate when close to other aircraft. Many pilots required the assistance of air traffic control to continue their flights.

Representative | Flight Global

Jamming incidents have never been specific to the US alone.

On October 16, there was a report from Flight Service Bureau Bulletin, warning of serious GPS interference at France’s Marseille-Provence airport.

In May 2016, Egyptian civil aviation authorities sent an internal alert warning pilot about malicious attempts at GPS signal jamming near Cairo airport. 

Very recently, the French Civil Aviation Authority (DGAC) raised the alarm about the Russian military jamming satellite navigation systems around Ukraine. Additionally, the EASA has identified four areas where the GNSS jamming intensified since February 24, 2022-the Kaliningrad region and the Baltic Sea, the eastern part of Finland, the Black Sea, and the Eastern Mediterranean area.

Representative | Geospatial News

The loss of GNSS data could also affect aircraft terrain avoidance and wind shear alerting systems.

All being said, the aviation industry is cognizant of the vulnerabilities of GPS, and actions are being taken to address them proactively.

The FAA’s Air Traffic Organization (ATO), for example, notes on its website that the agency is actively working with the U.S. Department of Defense to mitigate vulnerabilities and to make sure augmentation systems can detect and mitigate concerns.

According to a regulatory change proposed by the European Union Aviation Safety Agency (EASA), airliners are now allowed to carry a reduced amount of fuel required for diversions and delays, onboard.

Standard operating procedures require that airlines carry sufficient fuel on board to compensate for unforeseen circumstances such as possible diversions and delays caused due to holding pattern(s) and/or delays on approach to the destination airport or even the impossibility to land due to weather considerations or another issue.

Representative | Flight Deck Friend

Carrying extra fuel adds to the overall weight of an aircraft, which in turn translates to increased fuel consumption and total emissions from the flight. Any reduction in the carriage of this extra fuel would slash considerable CO2 emissions of the overall flight, thereby reducing the carbon footprint on the environment.

Touted to slash CO2 emissions by up to 3 million tons annually, which, approximately represents  1% of total European flight emissions.

Representative | PBS

According to EASA, the data on the amount of additional fuel required can be optimised, while continuing to ensure high safety levels. This can be achieved by improved risk assessments and calculations based on better data and better decision making.

The regulatory package, which consists of Regulation (EU) 2021/1296 and ED Decision 2022/005/R providing the AMC and GM, is aligned with guidance from ICAO. Additionally, these regulations will also be applicable for aircraft powered fully or partially by alternative energy sources, such as electric aircraft.

This regulatory package is part of the overall efforts of EASA to reduce the impact of aviation on the environment. There is no reason to lift up more fuel reserve into the sky than necessary – lifting fuel burns more fuel. Most importantly, this can be done without compromising safety – the reduction is possible thanks to better assessment methods and better data which allow airlines to carry out a more precise risk assessment.Jesper Rasmussen, EASA Flight Standards Director

The new rules bring in three different fuel schemes: basic fuel scheme, fuel scheme with variations and individual fuel scheme. The transition from the current rules to the basic fuel scheme requires little additional effort from the perspective of an air operator-said EASA. It further mentioned that the other two schemes are voluntary and will take more resources to implement as those require enhanced monitoring capabilities from the airlines. Furthermore, national authorities will also have to adjust their oversight to ensure that safety levels are not compromised.

Representative | Dauntless Jaunter

Apparently, the savings are touted to benefit long-haul flights to a greater extent. These are the flights that produce most of the CO2 emissions. According to Eurocontrol data, long-haul flights represent 6.2% of the flights but create 51.9% of the CO2 emissions.

The aforementioned regulations are expected to go on the floor by October 30, 2022.

In what can be termed a historic achievement for the country, India will soon be joining the likes of the United States, the United Kingdom, Australia, and Russia, to enter an elite group of countries boasting of fifth-generation stealth fighter jets with high-tech drones to accompany them.

The Combat Air Teaming System (CATS) ‘Warrior’

The CATS Warrior program is a collaboration between the state-owned HAL and an Indian private startup Newspace R&D. The project commenced in 2018 and was announced at Aero India 2021 as the Combat Air Teaming System (CATS) ‘Warrior.’

Defense Direct Education

A low-cost, pilotless aircraft with sufficient flight capability and intelligence to help manned and advanced fighter jets in combat is known as a loyal wingman.  The CATS Warrior bears an uncanny resemblance to the Kratos Valkyrie and Boeing’s Air Power Teaming System (ATS).

Kratos Valkyrie | Representative | Wikipedia

Primarily envisioned for the Indian Air Force, the CATS warrior will be an autonomous wingman drone and will team up with the existing fighter platforms of the IAF like Tejas, Su-MKI 30 and Jaguar, all of which will act like its mothership. These drones would be carrying mission-specific payloads, such as sensors, armament, or electronic warfare capabilities, and would be capable of flying ahead of their crewed counterpart.

Warrior will serve as a 'sensor amplifier' for the LCA, flying out ahead of the manned aircraft and using its sensors to feed information back to LCAHAL test pilot Retd Group Captain H.V. Thakur

Additionally, these "unmanned aircraft" can be deployed as low-cost decoys to help detect and overwhelm enemy air defences, and deflect fire from crewed fighter crafts as well. Owing to its "unmanned" nature, it can be sacrificed in case it cannot be flown back within its combat radius of 350 km. Furthermore, these drones could intercept targets on the ground and in the air.

A striking difference between CATS and its rival western programs is the emphasis on AI control. Although HAL has pitched for the drones to be capable of autonomous take-off and landing, the existence of dedicated two-seater control aircraft subtly hints that the "Warrior" might be, in some capacity, piloted.

Tech and specs (Warrior drone)

Powered by a modified HAL PTAE-7 or HAL-HTFE-25 turbofan engine, it features an internal weapon bay & hybrid design whose front section looks like a Boeing ATS wingman & from its mid-fuselage to its tail like the Kratos X2-58 Valkyrie.

Reportedly, the Warrior is undergoing wind-tunnel testing and flight testing is expected in 2024. The engine is expected to be certified by 2025.

"Loyal Wingman" developments around the world

On April 29 2021, the US Air Force carried out the first flight test of a "Skyborg" drone with a Kratos UTAP-22 Mako equipped with a bespoke autonomy system, moving the service one step closer to fielding an uncrewed “loyal wingman” for human pilots.
