Early tanks relied primarily on rolled homogeneous steel armour. Modern main battle tanks employ much more sophisticated arrangements involving combinations of high-strength steel, ceramics, composite materials, spaced armour and other specialised materials.
The latest research focuses on a particularly difficult part of the vibration spectrum: low-frequency vibration. Conventional rubber isolation systems can perform effectively once vibration frequencies rise sufficiently above the natural resonance of the mounting system, but isolating machinery operating at lower frequencies presents a much greater engineering challenge.
ISRO Chairman Dr V Narayanan said the space agency is simultaneously advancing several major programmes, including Gaganyaan and the Bharatiya Antariksha Station. The approval of the first BAS module marks an important step toward creating a permanent Indian presence in low-Earth orbit and expanding the country’s role in human space exploration.
Ahmedabad-based PierSight is developing a different approach to this problem by combining Synthetic Aperture Radar, or SAR, with space-based ship-identification data in the same maritime intelligence architecture. The company is building a constellation intended to provide persistent, all-weather monitoring of maritime activity, allowing vessels, oil spills and other activity at sea to be detected through darkness and cloud cover and then correlated with AIS or its newer VDES evolution.
DRDO Chairman Dr Samir V. Kamat has directly linked the organisation’s quantum-sensing research to submarine detection. He explained that DRDO is working on magnetometers capable of detecting changes in magnetic fields at the picotesla level and said such sensors could eventually be carried aboard UAVs or aircraft. According to Kamat, the technology could potentially enable submarine detection at depths of around 100 to 200 metres. The figure should presently be treated as a projected capability rather than a publicly demonstrated operational detection range.
Unlike conventional maize, popcorn varieties require kernels with characteristics that allow them to expand substantially when heated. High expansion is therefore an important commercial quality parameter, influencing the volume, texture and overall quality of the finished popcorn. The new hybrid is being promoted as a domestically developed, non-genetically modified option capable of producing the expansion characteristics required by the commercial popcorn industry.
The agreement was signed on August 21, 2026, in Bengaluru and focuses on strengthening collaboration in tactical cellular solutions. BEL said the partnership will promote development, technology exchange and knowledge sharing while enabling both companies to jointly work on advanced and reliable cellular communication systems suited to emerging operational requirements.
The contract covers the procurement of radar electronics by BEL, one of India’s principal defence public sector enterprises and a major supplier of military radar, electronic warfare, communications and weapon-control systems to the Armed Forces. Data Patterns has not disclosed the precise radar platform or programme for which the equipment will be supplied, and the available regulatory disclosure therefore does not support linking the order to any specific Indian Army, Navy or Air Force radar system.
Defence Minister Rajnath Singh and West Bengal Chief Minister Suvendu Adhikari carried out the Bhumi Pujan for the projects virtually from GRSE Bhavan in Kolkata on August 23. Three of the projects are being undertaken by GRSE at Raichak, Shalimar and Kidderpore, while YIL is establishing two major forging facilities at its Metal and Steel Factory at Ishapore. Together, the investments represent one of the more significant recent capacity additions to India’s state-owned defence manufacturing ecosystem.
EndureAir began publicly teasing VAHAK-6 on August 21, 2026, before confirming that the new system was on its way. The company has not yet released a complete technical specification for VAHAK-6, including its operational radius, deployment altitude, communications architecture or the exact configuration of the six carried UAVs. However, the concept points toward a carrier-and-deployed-drone architecture in which a larger UAV provides transport, reach and potentially communications support for a group of smaller aircraft.
