The HELINA missile is a third-generation anti-tank weapon with an infra-red seeker, fire-and-forget features. It is comparable with the wire-guided HJ-8 or Hongjian-8 system with the People’s Liberation Army (PLA) and BARQ laser-guided missile developed by Pakistan.
While the Indian Apache Longbow helicopters are fitted with Hellfire missiles with over 10 kilometers range, the Helina is the Indian answer to a helicopter launched anti-armor missile. The Indian military is also planning to equip upcoming HAL LCH helicopters with HELINA ATGM's to strike ground targets at high-altitude areas. Particularly in this case, HELINA can be a powerful deterrent against Chinese P-15 light tanks.
The significance of helicopter launched missile has assumed significance after the stand-off with the People's Liberation Army (PLA) in east Ladakh with the China deploying a large number of armor and rocket regiments in the battle theatre. HELINA provides an option of taking down enemy tanks beyond their range by using the fire and forget mode.
The HELINA system has an all-weather day and night capability and can take out enemy tanks with conventional and explosive reactive armor. The missile can engage targets in both indirect hit mode as well as the top attack mode. The IAF version of the missile is called Dhruvastra.
