In an era characterized by the relentless march of technological progress, armed forces worldwide are equipping themselves with cutting-edge systems, including loitering munitions, direct energy weapons, unmanned combat vehicles, ramjet artillery, and hypersonic missiles. Among these technological marvels, unmanned aerial vehicles, affectionately known as drones, have emerged as a transformative force.

The evolution of drone technology has undergone a seismic shift, largely attributed to the advent of additive manufacturing and 3D printing. This transformative wave has ushered in a marked reduction in production costs, democratizing access to drones not just for governments and commercial entities but also for civilians. The integration of Artificial Intelligence, Machine Learning, and the inclusion of Obstacles Avoidance Sensors has elevated these aerial machines to previously unimaginable levels of autonomy and operational finesse.

Drones manifest in an array of types, each meticulously designed to fulfill specific roles within designated operational theaters. High-Altitude Long Endurance (HALE), Medium-Altitude Long Endurance (MALE), and tactical UAVs, for instance, serve as the vanguards of long-range strikes. However, their substantial radar cross-section renders them vulnerable to radar detection, thus exposing them to the perils of air defense systems. Moreover, the prohibitive costs associated with their operation and maintenance restrict their utilization primarily to military entities.

In stark contrast, loitering munitions and drones classified under the small to micro category present a cost-effective and readily producible alternative. Their diminutive radar cross-section poses an enigmatic challenge for conventional radar systems, necessitating the imperative development of robust counter-Unmanned Aerial System (C-UAS) technologies.

The Armenia-Azerbaijan (Nagorno-Karabakh) conflict serves as a poignant reminder of the pivotal role of C-UAS systems. Armenia, lacking such defenses, sustained substantial losses. In stark contrast, Azerbaijani forces deftly deployed Israeli-made IAI Harop, an anti-radiation loitering munition, to effectively neutralize Armenian air defense systems, thereby carving out a secure passage for TB-2 UCAV strikes.

In the ongoing Russia-Ukraine conflict, loitering munitions have taken center stage, with Russia employing Zala Lancet and the Iranian-origin Shaheed-136, while Ukraine harnesses American Switchblade, Polish Warmet, and munition-laden First-Person-View (FPV) drones.

Notably, the rise of terrorist organizations such as the Houthis, Hamas, Hayat Tahrir-al-Sham, Lashkar-e-Taiba, and Al-Shabaab has ushered in an era of increased drone attacks. The attack on the Indian Air Force base in Jammu on June 21, 2021, serves as a stark testament to the urgent need for robust Indian counter-drone systems. This audacious incident resulted in minor injuries to two Indian Air Force personnel, prompting security agencies to cast a suspicious eye toward the involvement of the Lashkar-e-Taiba terrorist organization.

India has not been immune to the nefarious use of drones, with multiple instances of these aerial vehicles being employed for smuggling weapons and narcotics across its borders. The attack on the Indian Air Force base served as a catalyst for significant advancements in Indian counter-UAS system development, also known as Anti-Drone Systems.

Counter-UAS systems can be broadly classified into two distinct categories

  1. Soft Kill: This non-lethal method hinges on the art of jamming, specifically the interference with GPS or communication signals received by the targeted drone. RF-based jammers, such as the Leather Dazzler and Net Guns, exemplify this approach. The former is adept at disrupting the functionality of optical sensors through the inducement of disability glare.
  2. Hard Kill: In stark contrast, the hard kill method harnesses kinetic strikes to neutralize drones. This approach employs a plethora of weaponry, including anti-air guns, direct energy weapons, man-portable air defense systems, and micro anti-air missiles.

Several Indian companies have emerged as pioneers in the development of these cutting-edge counter-UAS systems. In this article, we embark on a comprehensive exploration of these systems, meticulously shedding light on their capabilities and their indomitable contributions to modern defense strategies.
