India successfully fired ATGM in lock-on before launch mode
NEW DELHI, ($1=76.29 Indian Rupees) — According to Army Recognition, the Indian Ministry of Defense successfully tested the HELINA anti-tank guided missile developed on the spot on April 12, 2022, from a light helicopter for the second time, BulgarianMilitary.com has learned, citing DefenceTurk.
- India to make indigenous chopper engine jointly with France
- India tested Barak 8 SAM – 2-way datalink and speed Mach 3
- BrahMos sea-to-sea missile did a precise strike at 500 km
Indian Air Force personnel and the Indian Army conducted the high-altitude test with the participation of the Defense Research and Development Organization [DRDO]. In this context, the second consecutive shooting and flight test was performed.
As part of the tests carried out on April 12, 2022, live shooting tests were conducted for different ranges and heights. Launched according to the planned mission, the missile destroyed the simulated tank target with superb accuracy. The tests were conducted with the participation of senior army commanders and a delegation of scientists from DRDO.
In in-flight tests, the missile is guided by an infrared search engine (IIR) operating in lock-on mode before launch [LOBL]. In this context, all HELINA systems, including the infrared image search device, have shown stable performance. Previously, HELINA validation tests were conducted at Pokhran in Rajasthan, proving the effectiveness of the missile in a desert environment.
LOBL Vs. LOAL
LOBL is an older method of launch that has retroactively become known as lock-on before launch, or LOBL, although this term is not commonly used and is a backronym to distinguish it from the LOAL method.
The new method is lock-on after launch, or LOAL, which is the capability of missile systems to lock on to their target after being launched from their carrier vehicle. The term is normally used for airborne weapons, especially air-to-air missiles. LOAL is an important part of modern weapon systems as it allows the weapons to be carried internally to increase stealth and then acquire the target once it has left the launching aircraft.
LOAL systems normally rely on cuing from a helmet-mounted sight or onboard sensors like radar or FLIR and use a simple strap-down inertial guidance system to know where to look after launch. Examples of LOAL weapons include the ASRAAM air-to-air missile and later versions of the AGM-114 Hellfire anti-tank missile.
HELINA anti-tank guided missile
HELINA is a third-generation anti-tank guided missile in the style of “shoot and forget”, which can be fired at targets in both direct strike mode and top attack mode. Although it can fire day and night in a variety of weather conditions, it can also attack conventional armored battle tanks as well as explosive jet armored main battle tanks.
The missile was designed to support both the Indian Army airborne forces and the mechanized infantry. In this context, it is designed to be launched from ground and air platforms. The ground version of this missile is offered integrated with the Nag missile carrier [NAMICA]. The missile in the helicopter launch configuration was called the NAG Helicopter Launch [HELINA].
Once the tests are successful, they will be able to be launched by the locally advanced light helicopter “Dhruv” [ALH] and the attack helicopter Rudra [ALH WSI]. Both helicopters are manufactured in India by Hindustan Aeronautics Limited [HAL].
