Will Nag/NAMICA-2 Combination Enter Service?

Though the successful test-firings of the Nag ATGM/NAMICA-2 combination passed its most crucial developmental milestone on September 8 and 9, 2017, this has perhaps come too late and it now remains to be seen if the Indian Army will conduct the definitive user-trials, without which service-induction cannot take place.
It may be recalled that user-trials of the 4km-range Nag ATGM’s uncooled LWIR sensor were carried out in hot desert conditions in Rajasthan on at the Mahajan firing range against both moving and static targets for different ranges of 2.8km and 3.2km, with the ATGMs then being fired from the NAMICA-1 tracked launchers.
Of the four missiles fired then, only one hit the target. In all, eight firing-trials were planned, between July and August 4. On July 28, while one Nag ATGM, tested for a range of 2,500 metres, hit the bull’s eye, the second failed to destroy a target 700 metres away owing to a problem in its uncooled LWIR sensor. In the subsequent trials on August 1, two Nag ATGMs missed their targets positioned at 1,300 metres and 2,500 metres, respectively, since there was inadequate thermal contrast for the LWIR sensor to lock-on and track the target before the missile was launched. Consequently, the uncooled LWIR sensor proved to be accurate only up to 2.5km in extremely hot conditions.
It was then that the Indian Army arbitrarily moved the goalpost by demanding that the DRDO re-engineer the NAMICA-1 by incorporating a commander’s panoramic target acquisition/lock-on sensor/ Undaunted, the DRDO rose up to the challenge and developed the NAMICA-2 (now housing a COMPASS optronic panoramic turret procured by Bharat Electronics Ltd from ELBIT Systems).
The DRDO also modified the LWIR sensor by incorporating IR-CCD processor chips supplied by France’s ULIS-SOFRADIR. Since then, this modified sensor has successfully engaged all eight of its targets—both fixed and moving.
Each NAMICA-2—destined for equipping the Recce & Support Battalions of the Indian Army’s Mechanised Infantry formations (especially when undertaking river-crossing operations)—can carry 12 Nag ATGMs, with six of them in ready-to-fire mode out to a distance of 4km. The ATGM has a flight speed of 230 metres per second, is armed with a 8kg tandem shaped-charge warhead, has a rocket motor using nitramine-based smokeless extruded double base sustainer propellant, has a single-shot hit probability of 0.77 and a CEP of 0.9 metres, and has a 10-year maintenance-free shelf-life.
On paper, the Indian Army remains committed to the procurement of 443 Bharat Dynamics Ltd-built third-generation Nag fire-and-forget ATGMs along with 13 OFB Medak-built NAMICA-2 tracked ATGM launchers.
Presently under development is the helicopter-launched version of the Nag, known as HELINA. This ATGM uses the same uncooled LWIR sensor as the Nag ATGM, and has a range of 7km. The HELINA, using the ‘Rudrastra’ cannister-encased twin-launcher system, will arm both the ‘Rudra’ helicopter-gunships as well as the LCH attack helicopters of both the Indian Army and Indian Air Force.
Under development is a DRDO-developed active fire-and-forget, adverse-weather millimeter wave (MMW) radar sensor for a 15km-range version of the HELINA. However, the R & D cycle of this ATGM is unlikely to be completed by 2019 at the very latest, and consequently, the Indian Army’s initial 60 HAL-developed ‘Rudra’ helicopter-gunships will in all probability be armed with up to 960 HELINAs equipped with LWIR sensors.

Mini-UAVs Will Get Zapped By EMP All Over NCR, For Starters

In the absence of comprehensive legislation governing the usage of privately-owned unmanned aerial vehicles (UAV) anywhere within Indian airspace, there has been a steady proliferation of mini-UAVs, especially those being imported from China. In the latest instance, a staffer of the Russian Embassy in Delhi was seen operating a mini-UAV within a designated no-fly zone in New Delhi:

Over the past two years, there were several other such instances in several cities throughout India, including a recent one in Mumbai that was spotted hovering dangerously close to the city’s international airport. Pending the drafting and approving of comprehensive legislation for deterring such min-UAV flights, the Union Home Ministry has just placed orders for an initial 12 vehicle-mounted high-power electromagnetic (HPEM) zappers from Germany’s DIEHL Defence for enforcing the no-flying zone directives within the Natgional capital Region. This is just for starters, and it will be followed in the near future by the CISF acquiring similar systems for ensuring the safety of air corridors around India’s major international and domestic airports.

The HPEM acts directly on the control electronics of mini-drones by means of electromagnetic pulses, thus causing mission abort. This means: regardless of the control method used (autonomous or radio-controlled), the mini-drone becomes inoperable upon impact of HPEM pulses at distances of up to several hundred metres and triggers the fail-safe function. The HPEM also provides the possibility of scalable range and the ability to also intercept entire swarms of mini-drones simultaneously. The HPEM does not cause harm to individuals and several of them are already being used worldwide for stopping cars and protecting large events (Olympic Games and summit meetings).
