Both are same missile with helina being a helicopter version of NAG. Nag was not successful because it could not lock on to the tank from a distance of 4 KM in desert heat of Rajasthan because seeker failed to lock on. The case of Helina is different. it need not lock on to the target right from the point of launch. Initially it will get a guidance from chopper. When it can identify and lock on the tank, it will do that and stop taking guidence from chopper. that is why Helina is a success and Nag is still under development. once the seeker of Nag is sufficiently developed to lock the tank from 4 km, it will be a success.Twinblade,
I thought Helina is a air born version of nag missile.but I keep hearing failures of Nag missile in trials whereas Helina missile trials have gone sucessfull?
Whats the difference between Helina and Nag? Do they use different seekers?
I think HELINA is planned for 16 KM. Its range shall be gradually increased, It will give us an ability to strike enemy beyond the range of the strike of any tank mounted anti chopper devise.is not 7 Km range too less for a mounted platform? Spike has versions upto 25Km . please correct me if i am wrong
https://en.m.wikipedia.org/wiki/Anti-tank_missileWhat are the distinguishing factors between our third generation missile like Nag and say, French Milan, or Israeli Spike which is apparently 4th generation? (or between any 3rd gen vs 4 gen in general)
Wrong comparison. kORNET is not Fire and Forget and lacks Top attack feature of NAG and SPIKE,HJ 12 or jevlin.Compared to kornet, javelin & spike basically
Spike is better but more expensive & generation ahead. Kornet has to keep lock on so it's worse than nag
Heavier than javelin but more range.
It's not high end but more than adequate. It's more about having a cheap missile for saturation & logistics.
42kg is more likely helicopter version, as that's around same as spike. & helicopter version is 10km.
& there we go man portable will be 14 less than all 3 major competitors.
Land versionEdit
Land based Nag will also have its range extended by development of a mast-mounted missile launcher that will be hydraulically raised out to a height of five metres to enable the Nag missile to acquire its targets out to a distance of 7–8 km.
Air-launched versionEdit
Air-launched version of Nag missile with 10 km-range launched from tactical interdiction aircraft like the upgraded Jaguar IS. It will use a nose-mounted millimetric-wave active radar seeker.
Man portableEdit
DRDL will also start working on the,`Man Portable' Nag very soon. It would weigh less than 14 kg.[7]
Beside Namica is the real deal, since so far only Russia has ifv with above 5km fire range atgm. Namica would be huge
NamicaEdit
NAMICA (Nag Missile Carrier) is a tank destroyer built for the army. It is equipped with a thermal imager for target acquisition. NAMICA is a modified BMP-2 ICV produced as "Sarath" in India

Whats pathetic is you shooting off your mouth. This is in LOBL mode. in LOAL mode, as in helina, the range is 10 km.45 kilo missile
4km range
PATHETIC
Apart from this Spike does have one more advantage to it which I think others lack. While almost all the Third Gen ATGMs are fire and forget type, Spike does have something called, Fire, observe and update. It means you don't need to have the target in your site at the time of launching. During the flight time when the missile is in elevation mode, you could guide the missile to its target through the connecting FOC.https://en.m.wikipedia.org/wiki/Anti-tank_missile
First-generation manually command guidedMCLOS missiles require input from an operator using a joystick or similar device to steer the missile to the target. The disadvantage is that the operator must keep the sight's cross hairs on the target and then steer the missile into the cross hairs—i.e. theline-of-sight. To do this, the operator must be well trained (spending hundreds of hours on a simulator) and must remain stationary and in view of the target during the flight time of the missile. Because of this, the operator is vulnerable while guiding the missile. The first system to become operational and to see combat was the French Nord SS.10 during the early 1950s.
Second-generation semi-automatically command guided SACLOS missiles require the operator to only keep the sights on the target until impact. Automatic guidance commands are sent to the missile throughwires or radio, or the missile relies on laser marking or a TV camera view from the nose of the missile. Examples are the Russian9M133 Kornet and the American Hellfire Imissiles. Again, the operator must remain stationary during the missile's flight.
Third-generation guidance systems rely on a laser, electro-optical imager (IIR) seeker or a W band radar seeker in the nose of the missile. Once the target is identified, the missile needs no further guidance during flight; it is "fire-and-forget", and the missile operator is free to retreat. However, fire-and-forget missiles are more subject to electronic countermeasures than MCLOS and SACLOS missiles. Examples include the German PARS 3 LR, Israeli LAHAT and Spike and the IndianNag.
Most modern ATGMs have shaped chargehigh explosive (HEAT) warheads, designed specifically for penetrating armor. Tandem-charge missiles attempt to defeat ERAprotected armor. The small initial charge sets off the ERA while the follow-up main charge attempts to penetrate the main armor. Top-attack weapons such as the Indian Nag, American Javelin and the Swedish Bill are designed to strike vehicles from above, where their armour is usually much weaker.
I think MMW seeker has been dropped from Nag missile and replaced with IIR seeker. MMW seeker is only meant for PGM and NGARM(Refer saurav jha interview with Satish Reddy)Along with this it does have the high frequency mmW active radar scanner which no other ATGM does have. Although it is a modular system to work as an option along with IIR, but given perfect environment, due to its high frequency its a sure shot and resistant to smoke screen or flares unlike IIR seekers.
Actually the whole concept was to build a missile which does use IIR and wire guidance for target acquisition. But DRDO was unable to come up with an effectivewire guidance system and so worked on IIR and mmW seeker. Although mmW being susceptible to interference much of importance has been given to IIR seeker. But during the summer trial in Rajasthan it has been found that the IIR seeker sometimes could not differentiate between tank heat and the heat generated by the surrounding, so along with its fine tuning mmW seeker has also been developed alongwith. Although its primary seeker would be IIR in Land launch version, but mmW being a modular system could be used in place of IIR.I think MMW seeker has been dropped from Nag missile and replaced with IIR seeker.

Yes , I have read about the interview but i don't think the Mmw seeker has been dropped for Nag but it will primarily be used for PGM and NGARM . Our pulsed MMw seeker have LOAL and LOBL capabilities and can be used in Rajasthan theater as there is low humidity so less attenuation and resonance especially being in W band and have one of the best ECCM capabilities . I don't find any reason why it also cannot be used. We can also use it in our CLGMs tooI think MMW seeker has been dropped from Nag missile and replaced with IIR seeker.
