Kh-35E Uran Missile Tested from INS Kora

The Indian Navy's missile corvette INS Kora reportedly test fired a Kh-35E Uran (NATO:SS-N-25 Switchblade) to its max range on October 30, 2020 in the Bay of Bengal hitting the target with precision. The Kh-35E is the export variant of the Ukrainian Kh-35 missile, a 620-kg subsonic cruise missile powered by a Motor Sich R95-300 turbojet engine. The missile features a 145-kg warhead and has a max range of 130-km. The missile cruises at 10-15-m above the sea, dipping down to 4-m during the end game.

India procured 400 Kh-35E missiles from Russia between 1998 to 2004 for use on Delhi (Project-15) and modernized Kashin-2 (Rajput) destroyers, Brahmaputra (Poject-16A) frigates, Kora (Project-25A) corvettes and Tarantul-1 (Vibhuti) FAC.

The IAF has the air launched variant of the missile, Kh-35E Zvezda (Star) (NATO designation AS-20 'Kayak). The Zvezda variant is also carried by IN IL-38 maritime reconnaissance aircraft.

Russia's Tactical Missiles Corporation developed Kh-35U variant of the Ukrainian Kh-35 missile entered Russian service in 2015.

The Kh-35U/Kh-35UE missile uses a UEC-Saturn engine, instead of the Ukranian Motor Sich engine. The Russian engine is reportedly a third shorter and lighter by several tens of kilograms, which facilitates improved characteristics of the entire product as a whole.

The Kh-35U features a dramatically reduced RCS as compared to the Kh-35, is 50-kg heavier than the Kh-35, and has twice the range (260-km) of the Kh-35.

The missile is designed to attack vessels up to 5,000 tonnes.

India is not known to have acquired the Kh-35UE export variant of the missile

The Reason Why India Declined the US Offer of MQ-9B Reaper Armed Drones

MQ-9B via Twitter


During the recent 2+2 Ministerial dialog between India and the US, the US reportedly pressured India into buying MQ-9B drones but India declined, denying President Donald Trump a foreign policy success that could have boosted his reelection chances. The deal would have secured US jobs (The USAF has lost interest in the Reaper, a weapon system honed for anti-terrorist operations, with its focus on the perceived combined threat from China and Russia) and reiterated Trump's tough anti-China posture.

 Multiple current officials speaking on the condition of anonymity told the US News that the Reaper sale was at the top of the agenda for Secretary of State Mike Pompeo and Secretary of Defense Mark Esper. India apparently signed the the Basic Exchange and Cooperation Agreement (BECA) for Geo-Spatial Cooperation on October 27, 2020, an agreement that would have facilitated MQ-9B sales, but declined to purchase the MQ-9B. 

It's likely that India declined the MQ-9 offer because of high per unit cost - roughly $100 million each factoring in infrastructure costs - and the drone's limited utility in the context of the current India - China stand-off in Ladakh.

The total cost of procuring 30 MQ-9 drones from the US was projected at $6 billion which likely includes weapons and logistics support.

While, US officials believe that the armed drone would perform a critical role in better preparing the Indian army for the threat it faces from the PLA and its fleet of drones, it's likely that the Indian armed forces, with limited financial resources at their disposal, don't agree. 

The ET on July 25, 2020 did report that the services were contemplating "an emergency procurement" of six Predator-B drones, 2 each for the 3 services, from the US in the context of the ongoing confrontation with China along the LAC. However, in July 2019, the HT had reported that the services were rethinking the drone procurement following the Iranian take-down of a US Global Hawk on June 20, 2019 using its S-300 AD system. The IAF had reportedly internally raised questions about an armed drone surviving in a contested air space like over Pakistan-Occupied Kashmir (POK) or along the Line of Actual Control (LAC) with both potential adversaries equipped with top of the line surface-to-air missile (SAM) systems. 

The very expensive MQ-9, which operates from medium altitude, would be an easy target for PLA's AD systems comprising S-300 and S-400 systems. Additionally, the PLA has HQ-16 (Buk) air medium-range and HQ-9 long-range ADS currently in service. 

Some sources told the US News that India may eventually buy the drones as part of a larger and more comprehensive arms package at some point in the future and that probably would be the best option for India.

Russia Tests Ship Based Missile Launched Rocket Propelled Torpedo

On October 28, 2020, the RuMoD in a press release announced that the second P-22350M frigate of the Northern Fleet "Admiral of the Fleet Kasatonov" fired a newly developed anti-submarine missile at the training grounds of the fleet in the Barents Sea.

"The shooting was carried out as part of the qualification serial tests of the product and was recognized as successful. One of the nuclear submarines of the Northern Fleet was involved in its support, which monitored the torpedo that had separated from the rocket in the underwater environment. Also, the frigate's rocket fire was provided by the crews of the Il-38 anti-submarine aircraft, the Ka-27 helicopter and the torpedo boat of the Kola flotilla of diverse forces.

"When performing rocket firing, the frigate's combat crews demonstrated confident possession of military equipment, high professionalism and naval training."

The wording of the press release suggests that the frigate may have successfully tested a shipborne missile launched variant of its vaunted air launched rocket propelled APR-3E torpedo, possibly designated APR-3M


The APR-3M is the latest variant of the APR-3 torpedo. 

In May, 2019, the Research and Production Enterprise ‘Region’ (part of Tactical Missiles Corporation) launched serial production of the torpedo. 

Enterprise CEO Igor Krylov told TASS, "All the trials of the APR-3M missile have been completed, the process of its serial production has been organized and its deliveries to the Russian Defense Ministry are underway. In the near future, we will also start promoting this missile for exports. The APR-3M is integrated into the armament of a Ka-27M modernized anti-submarine warfare helicopter." 


The APR-3E anti-submarine warfare torpedo is a follow-up of the APR-1, APR-2 and APR-3 missiles that were in service with the Soviet and Russian Navies. These munitions are among the world’s most effective anti-submarine warfare weapons.

The APR-3E is a rocket propelled light ASW acoustic homing torpedo with waterjet propulsion. It was developed by Russian Tactical Missiles Corporation JSC to engage current and future submarines at depth from the surface down to 800 meters at speed of up to 43+ knots, and it is a replacement for earlier APR-2 light antisubmarine acoustic homing torpedo.

The APR-3E variant of the torpedo is designed to be carried by fixed wing and rotary wing platforms including Tu-142, Il-38, Ka-28 and other aircraft. The torpedo requires at least 100 metres depth of water for the initial air-drop and can be deployed in conditions up to sea state 6.

Upon entering the water, the control surfaces of the torpedo enable the torpedo to travel in a spiral path with the help of gravity without starting the engine. During this stage, the acoustic seeker of the torpedo searches for targets. Once the target is identified, the engine starts and solid propellant rocket engine ensures the target has virtually very little or no time to react, thus increasing the kill probability.


The following are the specifications of the torpedo according to the Wikipedia.

Speed: > 56 kn
Range: > 3 km
Diameter: 350 mm
Length: 3.685 m
Weight: 525 kg (another 25 kg for accessory for aircraft deployment)
Propulsion: solid-propellant rocket-powered turbo-waterjet
Fuze: impact and proximity
Warhead: 74 kg
Seeker: acoustic
Seeker range: 1.5 km – 2 km
Maximum target speed: > 43 kn

DRDO's SMART Missile

The DRDO recently successfully flight tested the Supersonic Missile Assisted Release of Torpedo (SMART) from Wheeler Island off the coast of Odisha. 

The DRDO's SMART missile is conceptually similar to the weapon tested by Russia. However, the Russian missile is likely to be much more lethal if it delivers the rocket propelled APR-3E torpedo. Currently, DRDO's SMART delivers the indigenously developed battery powered TAL light torpedo with a max speed of 33 kn

All Foundational Agreements Signed , but What about Tech Transfer under DTTI?

The US in 2006 proposed that India sign the following 3 foundational agreements to facilitate increased defense co-operation

  • Logistics Support Agreement (LSA). Now known as  Logistics Exchange Memorandum of Agreement (LEMOA)
  • Communication Interoperability and Security Memorandum Agreement (CISMOA) 
  • Basic Exchange and Cooperation Agreement for Geo-Spatial Cooperation (BECA)

On October 27, 2020, India and the US signed the Basic Exchange and Cooperation Agreement (BECA) for Geo-Spatial Cooperation on October 27, 2020 following the third U.S.-India 2+2 Ministerial Dialogue. Earlier, in 2016, India and the US signed the   LEMOA and in 2018, COMCASA.

India has now fulfilled its end of the bargain in its quest to facilitate increased defense co-operation. How about the US.

In 2012, India and the US signed the Defense Trade and Technology Initiative (DTTI)  aimed at streamlining the approval process for release of US technology to India; removing bureaucratic hurdles with the aim of increasing defense trade and exploiting the potential for co-production/co-development.

Eight years later there has been no release of US technology to India.

The press statement by Raksha Mantri Shri Raj Nath Singh following India- USA 2+2 ministerial dialog in New Delhi on October 27, 2020 states

"In the Defence Industrial Cooperation area, we had a very candid and useful discussion. Recent initiative of 'Atmanirbhar Bharat' in Defence sector was underlined as a key driver and a guiding factor of our Defence Industrial Cooperation. I highlighted the capabilities of Indian Defence Industry and their usefulness in the supply chain of major US platforms and systems. We have identified priority Near-Term projects for joint development between respective agencies, which need to be fast tacked under the DTTI and resolved to work together in Defence R&D more efficiently."

The statement smacks of an underlying desperation on the part of India. As far as Atmanirbhar Bharat goes, India's strategic alliance with the US hasn't met Indian expectations. The alliance, however, has generously met US expectations through multi-billion dollar weapon system deals - P-8I, C-130, C-17, Apache 64E, Chinook Ch-47F - through government to government contracts. 

Despite having signed 3 ironclad agreements that increase its security dependency on the US, India has not been able to win US trust for transfer of defense technology. The fact is, India will never be able to win US trust. I think we all know that.

Not that the US has ever categorically expressed a willingness to transfer US defense technology to India. After eight years of dangling the carrot of technology transfer under DTTI, the US is now offering India a role in its defense systems supply chain through limited private sector partnership under initiatives such as Industrial Security Annex (ISA) and Indian Defence Innovation Organization (DIO-iDEX) and U.S. Defense Innovation Unit (DIU) tieup

While private sector defense supply chain tie-ups could help create jobs in India, they will not help make India self reliant in indigenous weapon system development and manufacture. More likely, such tie-ups would perpetuate Indian dependence on the US. More troublingly, they will give unprecedented leverage to the US over Indian economic and foreign policy. The US is notorious for its sanctions regime and India has been at the receiving end. The spread and granularity of US sanctions would have made Shylock look like an amateur.  

In contrast to the US approach on defense technology transfer, Russia has transferred to India technology for construction of nuclear power reactors for submarines and ships, cryogenic rocket engine, Brahmos missiles and Missile RF seekers without  any leverage.

Today, China is a very credible US adversary because the Soviet Union and then Russia transferred critical defense technology to China which China built upon to not just match but even pull ahead of US technology. India could have done the same; perhaps it can still do so without surrendering its sovereignty and becoming a US vassal.

Russia Well Prepared for US Hypersonic Weapons


When the US withdrew from the ABM treaty in June 2002, Russia indicated that it would develop hypersonic glide vehicle (HGV) warheads to counter any anti ballistic missiles systems that the US deployed to ensure the efficacy of the Russian nuclear deterrent. 

On  March 1, 2018, during a presentation to the Federal Assembly,  President of the Russian Federation, Vladimir Putin, unveiled a hypersonic maneuvering HGV warhead (later named Avangard) capable of penetrating deployed US ABM systems. He also unveiled an air-launched surface attack HGV capable of carrying a nuclear or conventional warhead. The HGV was later named Kinzhal. 

On December 27, 2019, RuMoD announced that the first regiment of Avangard hypersonic missile systems had gone on combat duty.

"Russian Defense Minister Army General Sergei Shoigu reported to Russia’s President Vladimir Putin that the first missile regiment armed with the latest Avangard strategic missile system with the hypersonic boost-glide vehicle assumed combat duty from 10:00 a.m. Moscow time on December 27, 2019," the ministry said in a statement.

In February 2020, Russia's Central MD commander announced that Kh-47M2 Kinzhal ALBMs will be deployed on MiG-31s in the 712th Fighter Aviation Regt at Kansk by 2024. The MOD has said 10 Kinzhal carriers are already on "experimental combat duty.

The two HGVs were among the 6 new strategic weapons unveiled by President Putin which included a nuclear powered torpedo with a thermonuclear warhead (Poseidon), a heavy intercontinental ballistic missile (Sarmat), a high-energy laser weapon (Persevet) and a nuclear powered cruise missile (Burevestnik).

In addition to the two HGVs unveiled on March 1, 2018, Russia is close to deploying a anti shipping hypersonic cruise missile - Tsirkon.

President Putin's March 1, 2018 speech and the subsequent operational deployments was clearly intended to convey the message that Russia has the technical expertise and the political will to maintain the credibility of its nuclear deterrent.

While developing hypersonic weapons to counter growing US anti missile capability, Russia remained aware of the inevitability of its adversaries eventually acquiring the same technology and started to develop technology to counter hypersonic weapons! 

In June 2020, while speaking to Russia-1's Vesti Nedely program on his government's work to gain an edge in the field of new strategic systems, President Putin reportedly said,  "I think that we can pleasantly surprise our partners with the fact that when they [get] these (hypersonic) weapons, with a high degree of probability, we will have a way of combating against them.” 

In the following paragraphs, I present a roundup of the progress made by Russia in countering adversary hypersonic weapons. 


On October 24, 2020, Russian military expert Igor Korotchenko, claimed on Radio Sputnik that the Russian military industry was already testing a missile system capable of shooting down enemy hypersonic missiles.

According to him, during a series of tests conducted a few months ago, the S-300B4 system demonstrated the ability to intercept and shoot down operational-tactical and, most importantly, hypersonic missiles, including those under development around the world.

The capability to engage hypersonic targets was based on a newly developed 400-km range missile of the S-400B4 system developed ammunition, which has a range of up to 400 km. 

Igor Korotchenko claimed on Sputnik radio that the new missile system was presented at the Army 2020 exhibition, which took place this year in Russia. He also said that Russia has already developed an export version of the system, which will be named Abakan. [source]

59N6-TE Mobile Radar

via Twitter

In June 2020, TASS reported that Russia's Rosoboronexport has started promoting on international arms markets the 59N6-TE mobile radar capable of detecting hypersonic targets, the company’s press office reported on Thursday.

"Today Rosoboronexport is bringing to the market the latest radar station capable of effectively detecting a wide range of advanced and future air objects, including hypersonic targets," the company’s press office quoted Rosoboronexport CEO Alexander Mikheyev as saying.

"While developing the export version of the radar, the growing role of air defense systems for the provision of security of states was taken into account, as well as the needs of foreign customers in the expansion of the reconnaissance capabilities of their air defense units," he said.

The 59N6-TE mobile three-dimensional station is an exclusively Russian-made product, which implies present-day Russian hardware components with digital processing and signal generation. It is fully solid-state and has high potential together with enhanced jamming resistance, according to the data posted on the company’s website.

via Twitter

"The 59N6-TE is a radar of medium and high altitude, having a decimeter wavelength range. Apart from hypersonic targets, it also effectively detects aerodynamic and ballistic objects," the statement says.

The 59N6-TE radar provides for the measurement of the range, azimuth and altitude of aerial targets. It is capable of detecting objects flying at a speed of up to 8 000 km/h at a range of up to 450 kilometers and at an altitude of up to 200 kilometers. After detection, it exchanges radar information with C4I systems. It operates in conditions of jamming and carries out direction finding of active noise jammers, Rosoboronexport said.

The station has an automatic and a semi-automatic mode of aerial targets’ acquisition and tracking. "In a real time mode, it can simultaneously track no less than 1 000 objects and recognize 8 classes of targets, which includes selection of anti-radar missiles and warning its own combat crew of the danger of elimination, inter alia, by high precision munitions and homing missiles. The 59N6-TE radar also includes equipment for the recognition of detected aerial targets in international radar recognition systems Mk-XA and ATC RBS," the company said.

The 59N6-TE radar set includes an antenna-hardware complex and an indicator post, placed on a standard vehicle chassis of the “KAMAZ-6560” type. There are also options to place the item on a single vehicle chassis, deploy it in a stationary version or to place the radar antenna system on a high tower support and other installations. Besides, the station is equipped with remote operator’s work stations, which may stay at a distance of up to one kilometer from the indicator post if connected via glass fiber links, and up to 15 kilometers in case of using a radio link.    

Air-to-air Missile with Multiple Homing Heads

In February 2020, Izvestia reported that Russia is designing an ultra-long-range air-based missile capable of intercepting high-speed and maneuvering targets. The weapon is designed to engage hypersonic aircraft and cruise missiles.

The missile is being developed for carriage by MiG-31 interceptor and its planned successor, the MiG-41. According to Izvestia, one of the candidates for the role of submunition is the medium-range missile K-77M.

The heavy long range missile will deliver a warhead with several modern air-to-air missiles over a distance of several hundred kilometers. The submunition missile will then separate from the carrier and begin to search and attack targets on their own using active homing.

Typically, an air-to-air missile has a single warhead and the chances of a lone warhead failing to successfully engage a hypersonic maneuvering target are very high. Using several active homing submunition missiles would increase the chances of a successful head on engagement.

The U.S. uses a similar approach for ballistic missile defense against ICBMs. Interceptor missiles launch “kill vehicles” with multiple warheads, each equipped with sensors as well as thrusters for rapid maneuvering. The submunition missile will disperse at a pre-calculated range to cover a larger area in a head on engagement. 

The use of a single information space would make the interception more effective. Ground-based radars, early warning radars, or an attack warning system could detect aerial targets, cruise or hypersonic missiles and transmit target information to an airborne MiG-31 which could launch an ultra-long-range missile towards the target area while itself staying well out of harm's way. 

Rezonans-NE VHF counter-stealth early warning phased-array radar

The Rezonans-NE VHF counter-stealth early warning phased-array radar is designed to effectively detect a wide range of current and future air targets, including low-observable cruise and ballistic missiles, hypersonic aerial vehicles, as well as stealthy ones, in severe electronic countermeasures (ECM) and clutter environment.

Rezonans radars operate in the meter band and employ the principle of wave resonance, which allows detecting aircraft based on stealth technology and also hypersonic targets flying at a speed of up to Mach 20. The radar is capable of detecting targets and issuing target acquisition on aerodynamic targets at a distance of 600 km and at a range of 1,200 km on ballistic targets, at an altitude of up to 100 km.

Russia's Northern Fleet already has 3 Rezonans-N in service as in February 2020: 2 in Arkhangelsk and 1 on Novaya Zemlya. According to an OPK source, two Rezonans-N radars will be deployed to the Kola Peninsula in the Russian Arctic in 2020.

INS Vikrant Basin Trials in October 2020: Really?


Going by this photograph of INS Vikrant posted by @DefencePROkochi on Twitter on October 25, 2020, INS Vikrant does not appear ready for basin trials.

The TNIE reported on October 4, 2020 that INS Vikrant is set to begin basin trials this month.

The TNIE had reported in August 2020 that NS Vikrant, is set to begin testing in waters (Basin Test) with its systems and equipment fitted.

Sources in Navy confirmed to TNIE that, “Harbour Trials have finished. The Basin Trials are planned for September.” Basin trials are conducted for proving of the propulsion (move), transmission (electricity) and shafting systems .

During his press conference on December 3, 2019 ahead of Navy Day December 4, 2019, CNS Admiral Karambir Singh stated that IAC will be fully operational by 2022 and will have MiG-29K aircraft.

Rudram - 1 : Next Generation Anti-radiation Missile (NGARM)


In April 2012, DRDO announced that it is developing an anti-radiation missile on  priority to equip Su-30MKI aircraft.

In August 2014, DRDO Chief Avinash Chander confirmed to the press that missile design is in progress and hardware is being readied for the first trials. 

"We expect successful trials of this ARM from an aircraft in about the next three years," he very optimistically said.

The missile, earlier known just as NGARM, was first officially referred to as Rudram-1 in a tweet by RM Rajnath Singh on October 9, 2020 while announcing a successful test of the missile on the same day. 

Missile Characteristics

Rocket Motor

NGARM reportedly employs an indigenously developed dual-pulse, solid-propellant rocket motor.


RCI is developing  the MMW seeker for the NGARM. The seeker is reportedly a combination of passive and active radar.


The missile uses a an inertial navigation system (INS) that is aided by GPS.

Targeting Pod

The NGARM would be cued using the DRDO developed Siva HADF (High Accuracy Direction Finder)

Test on October 9, 2020

The Rudram NGARM was successfully Flight tested on October 9, 2020 onto a radiating target located on Wheeler Island off the coast of Odisha. The missile was launched from SU-30 MKI fighter aircraft. 

According to the PIB release following the test, Rudram, "has INS-GPS navigation with Passive Homing Head for the final attack. The RUDRAM hit the radiation target with pin-point accuracy. 

"The Passive Homing Head can detect, classify and engage targets over a wide band of frequencies as programmed. The missile is a potent weapon for IAF for Suppression of Enemy Air Defence effectively from large stand-off ranges."  

Photographs released with the PIB release show the launching Su-30MKI sans the HADR pod, indicating that the missile was launched in LOBL mode.

Test on January 18, 2019

“The missile was tested from a Sukhoi-30MKI on January 18, 2019 at the integrated test range at Balasore. The missile, with all systems functioning properly, hit the designated target with a high degree of accuracy in the Bay of Bengal. The NGARM can be launched from Sukhois from different altitudes and velocities,” said a source.

The test was likely sans a seeker

Missile Specifications

The missile will have a strike range of 15-100 km from launch altitudes of 100 m to 15 km from Su-30 MKI aircraft.

It will be carried by Su-30MKI on a modified AKU-58 launcher.
