Agnikul Cosmos, an aerospace start-up based in Chennai, the world’s first single-piece 3D-printed engine for their launch vehicle the Agnibaan, is set for a test flight and will likely take off by the end of the year

In a ground breaking move, Agnikul Cosmos, an aerospace start-up based in Chennai specialising in the development of satellite launch vehicles, is set to launch its inaugural flight with the world’s first 3D-printed engine before the close of this year, according to a report by the Economic Times.

The upcoming mission serves as a technological demonstrator, and is supposed to emulate Agnikul’s planned orbital launch — the first commercial launch anticipated in 2024 — but on a smaller scale.

“We are looking to launch by the end of the year. One test is pending, which will be conducted on our campus at IIT-Madras. Once the final reviews with ISRO (Indian Space Research Organisation) are complete, we are good to go as the launch vehicle is already at the launch pad,” stated Chief Executive Srinath Ravichandran told reporters. “This isn’t a sounding rocket and is a complex machine, so we want to get it right in the first attempt.”

Should the mission prove successful, the start-up, incubated at the Indian Institute of Technology, Madras campus, will become India’s second private company to develop a small satellite launch vehicle. The first, Skyroot Aerospace, launched the Vikram S in November 2022.

Ravichandran highlighted a key distinction between Agnikul’s rocket, Agnibaan, and the Vikram S. While the Vikram S was a sounding rocket launched from guide rails, Agnibaan would lift off vertically, following a predetermined trajectory and executing precisely orchestrated manoeuvres during flight.

Agnibaan SOrTeD (SubOrbital Technological Demonstrator) is a highly customizable, single-stage launch vehicle capable of carrying up to 300 kg payload to orbits around 700 km above the ground (basically into the low Earth orbits). Anirban follows a plug-and-play configuration, adapting to the size of the satellite taken to space.

One of the biggest differences comes in the propellant system that Agnikul is using and how they resize their launch vehicles. Because they offer customisable sizes of launch vehicles, they can configure the vehicle for a particular payload size or satellite size. Furthermore, liquid propellants, used in Agnikul’s rocket, are reusable and safer compared to solid propellants.

Agnikul’s patented Agnilet engine stands as the world’s first single-piece 3D-printed engine, designed and manufactured entirely in India. Successfully test-fired in early 2021, this achievement marked a significant milestone for 3D printing technology in India, which traditionally have been reserved for medical implants.

The integration process of the launch vehicle, located at the Satish Dhawan Space Centre in Sriharikota, with the company’s private launchpad, was completed on August 15.

Agnikul’s customer base encompasses entities building small satellites aiming for a low Earth orbit, with payloads mainly consisting of communication and imaging satellites.

The Agnikul 3D printing Rocket Factory houses a metal 3D printer from EOS, along with other machines facilitating end-to-end manufacturing of a rocket engine within a single facility.

INS Arihant’s Nuke-Capable K-4 Submarine-Launched Ballistic Missile ‘Ready To Roll’

INS Arihant’s Nuke-Capable K-4 Submarine-Launched Ballistic Missile ‘Ready To Roll’


NEW DELHI: India tested its nuclear capable K-4 submarine-launched ballistic missile (SLBM), designed to have a strike range of 3,500 km, for the second time in six days on Friday. The missile test, as the one conducted on January 19, was undertaken from an undersea platform in the shape of a submersible pontoon off the coast of Andhra Pradesh according to a report by Rajat Pandit of TOI.

The solid-fuelled K-4 missile is being developed by DRDO to arm the country’s nuclear-powered submarines in the shape of INS Arihant and its under-development sister vessels. INS Arihant, which became fully operational in November 2018 to complete India’s nuclear triad, is currently armed with the much shorter K-15 missiles with a 750 km range.

“The K-4 is now virtually ready for its serial production to kick-off. The two tests have demonstrated its capability to emerge straight from underwater and undertake its parabolic trajectory,” said a source.

India has the land-based Agni missiles, with the over 5,000-km Agni-V inter-continental ballistic missile now in the process of being inducted, and fighter jets jury-rigged to deliver nuclear weapons. But INS Arihant gives the country’s deterrence posture much more credibility because nuclear-powered submarines armed with nuclear-tipped missiles are considered the most secure, survivable and potent platforms for retaliatory strikes.

Once the K-4 missiles are inducted, they will help India narrow the gap with countries like the US, Russia and China, which have over 5,000-km range SLBMs. The K-4 missiles are to be followed by the K-5 and K-6 missiles in the 5,000-6,000 km range class.

The 6,000-ton INS Arihant, which is propelled by an 83 MW pressurised light-water reactor at its core, in turn, is to be followed by INS Arighat, which was launched in 2017. The next generation of nuclear submarines, currently called S-4 and S-4*, will be much larger in size.

After Upgradation, Sukhoi Su-30MKI Indigenisation To Reach 78%


India has received clearance to upgrade 84 Sukhoi Su-30MKI fighter jets, which will result in 78% indigenization after the upgrade

In a significant step towards bolstering its military might with indigenously developed technology, India is poised to witness its Russian-origin Sukhoi Su-30MKI fighter jets evolve into a domestic platform. Speaking at a recent lecture.

The upgrade program is being led by Hindustan Aeronautics Limited (HAL) in partnership with the Indian Air Force and other partners. The upgrade is expected to cost US$7.5 billion.

The Defence Acquisition Council (DAC) granted Acceptance of Necessity (AoN) for the upgrade. The upgrade is part of India’s efforts to improve the capabilities of its primary fighter aircraft, it refers to as the “Super Sukhoi”.

This initiative is a part of a larger effort by the Indian Air Force to modernize its ageing fleet. Air Chief Marshal Chaudhari asserted the critical role of an offensive air force as demonstrated in current global conflicts and emphasized India’s move towards an indigenized arsenal. To this end, the IAF has been proactive, from upgrading its Mirage 2000 to enhancing its MiG-29 fleet.

In summary, the IAF’s commitment to updating their combat forces with the latest technology, including shifting to fifth-generation fighter jets, ensures operational preparedness and a strong deterrence capability. The gradual indigenization of its air fleet marks a pivotal shift in India’s defence landscape, reducing dependency on foreign imports and fostering technological sovereignty.

Akash Weapon System Exports For The Armenian Armed Forces Gathers Pace


According to unconfirmed reports, Armenia is a top contender for an export order for Akash SAM system manufactured by Bharat Dynamics Limited (BDL).

While there is no official confirmation because of the sensitivities involved, documents suggest that the order for the same has already been placed the report further added.
There are nine countries, in turn, which have shown interest in the indigenously-developed Akash missile systems, which can intercept hostile aircraft, helicopters, drones and subsonic cruise missiles at a range of 25-km. They are Kenya, Philippines, Indonesia, UAE, Bahrain, Saudi Arabia, Egypt, Vietnam and Algeria reported TOI.

The Akash export version will also be slightly different from the one inducted by the armed forces. The 100-km range air-to-air Astra missiles, now entering production after successful trials from Sukhoi-30MKI fighters, also have “good export potential”, said sources.

Akash is a “tried, tested and successfully inducted systems”. Indian armed forces have ordered Akash systems worth Rs 24,000 crore over the years, and MoD inked a contract in Mar 2023 of over Rs 9,100 crores for improved Akash Weapon System

BDL is a government enterprise under the Ministry of Defence that was established in 1970. BDL manufactures surface-to-air missiles and delivers them to the Indian Army. BDL also offers its products for export.

Akash Weapon System

The AWS is a Short Range Surface to Air Missile (SRSAM) Air Defence System, indigenously designed and developed by Defence Research and Development Organisation (DRDO). In order to meet aerial threats, two additional Regiments of AWS with Upgradation are being procured for Indian Army for the Northern borders. Improved AWS has Seeker Technology, Reduced Foot Print, 360° Engagement Capability and improved environmental parameters.

The project will give a boost to the Indian missile manufacturing industry in particular and the indigenous defence manufacturing ecosystem as a whole. The project has overall indigenous content of 82% which will be increased to 93% by 2026-27.

The induction of the improved AWS into the Indian Army will increase India’s self-reliance in Short Range Missile capability. This project will play a role in boosting the overall economy by avoiding outgo of precious foreign exchange to other countries, increasing employment avenues in India and encouraging Indian MSMEs through components manufacturing. Around 60% of the project cost will be awarded to the private industry, including MSMEs, in maintaining the supply chain of the weapon system, thereby creating large scale of direct and indirect employment.
