In a thought-provoking address in Jabalpur, Madhya Pradesh, retired Army Major General GD Bakshi delivered a staunch critique of caste-based politics in India, emphasizing the need for national unity. His comments came during an event aimed at addressing the ongoing issues related to caste divisions even after 78 years of Independence.

Bakshi highlighted that the concept of caste was introduced by the British to implement a “divide and rule” strategy. He expressed dismay that, despite decades of independence, caste politics continues to plague the nation. “Hum sab Bharatiya hain… We all are Indians!” Bakshi declared, asserting that the notion of caste does not exist within the Indian lexicon, pointing out that the term originated from a Portuguese word, ‘casta.’ He questioned the essence of Indian identity by asking, “If I am Bakshi, you are Gupta, other is Singh, then who here really is an Indian?”

Emphasizing the dangers of division caused by caste, Bakshi advocated for reservation policies to be based on economic criteria rather than caste affiliations, arguing that genuine unity among all Indians can only be achieved by moving past these outdated divisions.

Bakshi did not shy away from addressing political figures, subtly criticizing former Jammu & Kashmir Chief Minister Mehbooba Mufti for labeling Hindutva as a “disease.” Without directly naming her, he retorted, “Sabse badi bimari to wo khud hain!….She herself is the biggest disease!” His assertion was that Mufti’s leadership had led the nation to experience significant challenges.

The conversation then shifted to the Agniveer program, which was introduced by the central government in June 2022. Bakshi expressed that the initiative had been rushed and lacked thorough planning. Drawing on his personal experiences from the Bangladesh War, he stated, “When I was fighting the war with Bangladesh, its tenure was 7 years. At present also, the tenure should be increased from 4 years to 7 years.” He stressed that extending the serving period would benefit both the soldiers and the armed forces.

Bakshi also raised concerns over the rising instances of attacks on Hindus and temples in Bangladesh, calling for a collective struggle to protect religion and culture. He urged a sense of solidarity among the Indian populace, asserting that overcoming divisions based on caste and religion is essential for building a robust and prosperous nation.

The event served as a platform for Major Bakshi to articulate his commitment towards preserving Indian culture and advocating unity among its diverse communities. He concluded his remarks with a powerful call for collective action, encouraging all Indians to unite for a brighter future.

India’s indigenous light tank has marked a significant achievement after successfully firing multiple rounds at varying distances at a high altitude exceeding 4,200 meters.

In a remarkable achievement for the Indian academic community, Rishabh Bhattacharya, a third-year student at the International Institute of Information Technology (IIIT) in Hyderabad, has secured first prize at a prestigious Indian Navy event. His innovative algorithm, designed to enhance navigation and real-time tracking of aerial objects such as drones, has earned him a cash award of Rs 3 lakh. The accolade was announced during Swavalamban 2024, an event focused on innovation and indigenisation organized by the Indian Navy.

Bhattacharya’s optical flow tracking algorithm has been praised for its ability to achieve sub-pixel accuracy, a critical feature that allows for precise motion estimation and tracking. The algorithm also effectively navigates environmental challenges such as poor lighting conditions, rapid object movements, and intricate textures.

The Swavalamban seminar, held in October, featured a nationwide competition aimed at addressing various operational challenges through technological innovation. Participants were invited to tackle problem statements that encompassed a range of topics, including swarm drone coordination and maritime situational awareness, with Bhattacharya choosing to focus on the navigation and tracking of flying objects.

Drawing inspiration from his prior research presented at the IEEE International Conference on Robotics and Automation (ICRA) 2023, Bhattacharya emphasized the importance of resilience in technological solutions. “One of the criteria laid out was for the solution to demonstrate resilience to varying lighting conditions, rapid movements, and complex textures while maintaining efficiency on platforms like drones or embedded systems,” he said.

Creating an algorithm capable of functioning effectively under these constraints was no easy feat, particularly given the inherent unpredictability of flying objects. Bhattacharya explained the complexities involved in tracking such objects necessitated sophisticated detection and tracking mechanisms that could operate in real-time.

To overcome a lack of comprehensive datasets, he innovatively merged a flying objects dataset from Sekilab—containing planes, helicopters, and birds—with a user-generated UAV dataset from the platform Kaggle. By employing semantic separation techniques, he generated a synthetic dataset that could simulate varied motion scenarios, making the dataset versatile and rich for training purposes.

The combined dataset, totaling 7.7 gigabytes, is set to be released publicly, providing a valuable resource for the wider research community. In a bid to enhance algorithm performance under challenging environmental conditions, Bhattacharya integrated a framework he had developed earlier, known as Gated Differential Image Processing (GDIP). This framework optimizes object detection models, such as YOLOv8, making them more adept at operating in low-visibility situations like foggy weather.

The model underwent training with the comprehensive dataset over 50 epochs and was fine-tuned for real-time applications, achieving a processing speed of approximately two milliseconds per frame. Rigorous testing confirmed its reliability in varying lighting conditions, complex textures, and unpredictable movements.

Bhattacharya credits his success in part to his experiences at the Machine Learning Lab, where he worked under the guidance of Dr. Naresh Manwani. He recalled engaging discussions on research papers that helped shape his final solution. The seminar provided an invaluable opportunity for Bhattacharya to present his work directly to Navy admirals and commanders, who expressed genuine interest in potentially integrating his solution into operational frameworks.

“Meeting Navy officials who appreciated and discussed my work was an inspiring moment,” Bhattacharya remarked, reflecting on the significance of his accomplishment and the potential impact of his research on future maritime operations.

In a significant advancement for the Indian Navy’s operational capabilities, a ‘steel cutting’ ceremony was conducted at the L&T yard in Kattupalli, Tamil Nadu, heralding the production of the second fleet support ship (FSS) as part of a broader initiative to fortify naval replenishment at sea. This development aligns with a ₹19,000-crore contract signed by the defence ministry with Hindustan Shipyard Ltd (HSL) in August 2023 for a total of five such vessels.

The ceremony on Wednesday took place eight months after the initial steel cutting of the first FSS at HSL in Visakhapatnam. The new vessels are designed to provide essential supplies—fuel, water, and ammunition—to the navy’s warships during missions, effectively expanding their operational range and endurance without the need to return to port.

Highlighting the collaborative efforts within India’s maritime industry, the navy emphasized the importance of the public-private partnership model. HSL has engaged L&T Shipyard for part of the construction of two fleet support ships, which is expected to optimize the country’s shipbuilding capabilities while adhering to tight delivery timelines.

The navy anticipates the delivery schedule to commence with the first vessel in mid-2027, followed by subsequent ships delivered at intervals of ten months. The FSS vessels are projected to be 225 meters in length and 32 meters in width, with a displacement of 40,000 tonnes. When operational, these vessels are expected to significantly augment the navy’s ‘blue water’ capabilities, facilitating prolonged naval operations without the necessity of returning to shore.

In addition to their primary mission, the fleet support ships will also be equipped to assist in humanitarian aid and disaster relief (HADR) operations, reflecting the navy’s commitment to versatile maritime engagement.

The project is poised to enhance India’s shipbuilding sector, with a focus on indigenous design and sourcing, in alignment with government initiatives like Aatmanirbhar Bharat, Make in India, and Make for the World. The sustained investment in these fleet support ships is part of the navy’s overarching strategy to become fully self-reliant by 2047, coinciding with the country’s celebration of a century of independence.

Moreover, this initiative is projected to create substantial employment opportunities, generating nearly 168.8 lakh man-days over the project’s eight-year timeline. The Indian Navy currently operates four fleet support vessels, commissioned between 1996 and 2011; thus, the addition of these new ships is essential to meet the increasing demands of naval operations in the Indian Ocean region.
