The 90m Club in Men’s Javelin: As Neeraj Chopra Breaks Barrier
- Late Friday night in Doha at the Diamond League, the rather exclusive 90m club in men’s javelin throw found not one, but two entrants. First, off his third attempt, India’s Neeraj Chopra achieved a long-standing dream. He had been knocking on the door for ages but finally he broke it down with a mammoth 90.23m throw to become the 25th man in history to achieve the feat. But there was to be another late twist. Germany’s Julian Weber got ticket No 26 into the list, throwing 91.06m and pipping Neeraj to the title. The organisers of the event called it “one of the greatest javelin competitions of all time.”
- Zelezny, who holds the world record for the longest throw (98.48m), does not attend Diamond League tournaments, but he came with Neeraj on Friday because he felt “today is the day to achieve 90m.”
- Competing at the Qatar Sports Club Stadium, Neeraj got off to a brilliant start with a strong 88.44m throw in his very first attempt, which immediately put him in the lead. His second attempt was a foul, but he bounced back in style with his third — launching the javelin to a staggering 90.23 metres. That effort not only marked a career-best for Chopra but also made him the latest entrant in the elite 90m club, a mark considered the gold standard in javelin throwing.

Agnikaa Jet Series: India’s First Jet-Powered Loitering Munition
- Adani Defence and Aerospace has unveiled the groundbreaking Agnikaa jet series, marking a significant milestone as India’s first indigenous jet-powered loitering munition line.
- This advanced weapons system, with variants including the Agnikaa (J1), H1, H2, and H3, represents a major leap in India’s defence manufacturing capabilities.
- With a weight of 25 kg, impressive flight duration of 1 hour, and an operational range of 190 km, the Agnikaa series is designed to fulfil diverse mission requirements ranging from short-range tactical operations to long-range strategic strikes.
- Loitering munitions represent a revolutionary category of weapons that combine the advantages of UAVs with precision strike capabilities. These systems are designed to “loiter” in a designated area, conducting surveillance and reconnaissance while waiting for targets to present themselves before executing a precision strike.
- The Agnikaa jet series represents Adani Defence’s entry into this sophisticated weapons category, with India joining a select group of nations capable of producing advanced loitering munition systems.
- The base specifications of the Agnikaa platform include a relatively lightweight design of 25 kg, which enhances its deployability and reduces logistical requirements.
‘Golden Dome’ Missile Shield for US
- US President Donald Trump announced a new missile defence initiative, the ‘Golden Dome’, aimed at shielding the country from foreign threats. He revealed that a bill currently in Congress proposes a $25 billion allocation for the project.
- He said that “everything” in the Golden Dome missile defence shield he is planning will be made in the United States.
- Trump further stated that Canada has shown interest in joining the Golden Dome project, and the US would support its northern neighbour in this effort.
- Initially ordered by Trump in January, the Golden Dome project aims to build a satellite-based network capable of detecting, tracking, and possibly intercepting incoming missiles. The system could involve the deployment of hundreds of satellites dedicated to missile surveillance and response.
- The Golden Dome concept draws inspiration from Israel’s Iron Dome, which defends against rockets and missiles.
Indigenously Built Synthetic Aperture Radar Drone
- India’s first indigenously built Synthetic Aperture Radar (SAR) drone, developed by Sisir Radar, represents a major leap in the nation’s Earth observation and defence technology capabilities.
- This drone platform is entirely designed and manufactured in-house by Sisir Radar, a Kolkata-based start-up led by renowned radar expert Tapan Misra, known for his pivotal roles in ISRO’s imaging satellite programs and the NISAR mission.
- The SAR systems support both 2D and 3D imaging, and their automatic registration with map references enhances usability for strategic operations.
- Sisir Radar’s P-band SAR is the world’s highest-resolution in its class and is flown on a drone, a global first.
‘Ancient Stitched Ship’ Inducted Into The Indian Navy
- The Indian Navy formally inducted and named the Ancient Stitched ship as INSV Kaundinya at a ceremonial event held at Naval Base, Karwar.
- INSV Kaundinya is a stitched sail ship, based on a 5th century CE ship depicted in the paintings of Ajanta Caves. The project was initiated through a tripartite agreement signed in Jul 2023 between the Ministry of Culture, the Indian Navy, and M/s Hodi Innovations, with funding from the Ministry of Culture.
- The Indian Navy played a central role in the project, overseeing the design, technical validation, and construction process. With no surviving blueprints of such vessels, the design had to be inferred from iconographic sources.
- The ship will now embark on her next historic phase, involving preparations for a transoceanic voyage along the ancient trade route from Gujarat to Oman, scheduled for later this year.
- Kaundinya became a young Brahmin scholar in Kapilvastu in the Sakya kingdom of King Suddhodana. He was one among the group of scholars who were invited to the royal court to predict the destiny of Crown Prince Siddhartha at his naming ceremony.
- The Kaundinya gotra is a specific lineage or clan within the Hindu tradition, primarily associated with certain Brahmin families. It is named after the ancient sage, Rishi Kaundinya. Individuals within this gotra trace their lineage back to Kaundinya and are considered part of this particular branch of the Brahmin community.
Operation Kagar
- In the din of Operation Sindoor, the media perhaps missed another crucial operation – Operation Kagar. It was launched on April 21, around the Karreguttalu hill range straddling Telangana and Chhattisgarh, to neutralise the Maoists staying in the dense forests.

- Based on intelligence inputs that about 400 Maoists, including top leaders, were camping in Karreguttalu, the operation was launched covering an area of 288 sq km. The “biggest operation till date”, as stated by Home Minister Amit Shah, was monitored by top officials all the way. The CRPF Director General, G P Singh, even camped in the area till it was called off on May 11.
Project Kusha Air Defence System
- India’s DRDO has embarked on one of its most ambitious air defence initiatives through Project Kusha, an indigenous long-range surface-to-air missile system designed to rival the capabilities of foreign systems like the Russian S-400.
