NEW DELHI: After a delay of a few months due to Covid-19, the Indian Army’s surveillance capabilities have received a major boost as Israel has delivered advanced Heron drones under the emergency procurement clause to keep an eye on the Chinese activities in the Ladakh sector. “The advanced Heron drones have arrived in the country and are being deployed for surveillance operations in the eastern Ladakh sector,” top government sources said. These drones are operational now and are far more advanced than the Herons in the existing inventory and their anti-jamming capability is much better than their previous versions, sources said. The acquisition of these drones has been done under the emergency financial powers granted by the government to the defence forces under which they can buy equipment worth Rs 500 crore to upgrade warfighting capabilities.
