Imp Point -
The missile is launched from the NAG missile carrier (NAMICA) which is capable of carrying up to six combat missiles. The robust imaging algorithm has made the missile hit the target at four-kilometredistance even in severe summer desert conditions which is unique in its class.
As part of the NAG summer user trials, six missions were conducted under the extreme temperature conditions of the Pokhran Ranges. All the missiles have met the mission objectives including minimum range, maximum range, in direct attack as well as top attack modes and achieved a direct hit onto the target.
Probably the coolest thing I've seen in a while. Thanks for posting this.
After the successful completion of the summer trails NAG is now cleared for production , which is to begin at the end of this year.
After more than a decade of development and trails and some rather unreasonable demands from the end user , it is finally going into production.
The biggest problem faced by NAG was its infra-red seeker.
The IR seeker could identify and engage the target if the environment was cool enough for the differential temperature between target and surrounding was a mere two degrees. But if the target tank was left for hours in summer sun, that is what as done during previous day time trials (carried out between 11 a.m. to 3 p.m), the temperature difference between the tank and the environment become negligible and NAG could not meet the targeted four km range and neither could JAVELIN nor SPIKE ATGM during their desert trials.
So to overcome this , a cryogenic cooling unit was used to cool the highly sensitive IR seeker. This allowed the seeker to discriminate between the thermal signatures of its targets vis a vis the background noise in three different scenarios.
1. Thermal differential within the target(this allows NAG to see targets which have uneven thermal profiles , eg barrel after firing is hotter than the target and the surroundings or running engine exhaust even though rest of tank is at same temperature as the surroundings.)
2. Thermal differential between the target and the background.
3. Surrounding temperature variations.(Presence of a target even at the same temperature as the surroundings sometimes creates minute localised temperature variations around the target due to many reasons like movement , flow of sand particles from running track etc which the modified seeker can pick up by running it's target discrimination algorithms against the thermal profile picked up by its seeker.)
This allowed the modified NAG ATGM to hit targets at minimum of 400m to maximum of 4 km at searing temperatures of 50-55 degree centigrade successfully even with a very low thermal contrast of target vis a vis background surroundings to the tune of a mere 0.2 degree Celsius.

"The robust imaging algorithm has made the missile hit the target " this is the required change which we did to identify the target (Battle Tank) when the environmental temperature and the target (battle tank) temperature is nearly equal i.e. by identifying the target using its outer shape. We should continuously work on our IR seeker and image algorithm code and also upgrade our Nirbhay air-launched missile with these hardware and software as a standoff weapon like SCALP, JASSM ... to hit missile launcher sites or any moving missile launcher vehicle ...
Indian Army successfully tests indigenously developed NAG anti-tank guided missile! It’s a huge success
Nothing new except : "It has been reported earlier that the NAG missile has successfully cleared the winter trials earlier this year and the government has already issued the Acceptance of Necessity for induction of NAG after user trials."

Hmmm.......650 km ? sounds about right.View attachment 8437
When you see it
@Parthu @randomradio @Milspec @GuardianRED @Gautam @kurup @Himanshu
Incomplete sentence ?!?!?!
Holy sh*t !!! Guys you should see this :
340 Km in power "on" mode !! Is there a power "off " mode ? Don't ramjets need intake air speed to be supersonic to work ? Is there going to be booster for getting it to necessary starting speeds ? If so wouldn't the over all range exceed 340 km ?
Even without any of that 340 km is one kick *censored* range. Put this thing in a ground launch cannister and we have our own S400.

Nothing strange.
That's why there are doubts whether XRSAM will also use this missile. With it, we can get ranges between 250-400Km depending on type of booster used. I had pointed this out a long time ago.
In fact this missile can be used to replace the Barak 8 also, primarily for ships.
If you look at the schematic
The booster grain is packed inside the combustion chamber. Upon the burning of the booster grain, the empty space forms the combustion chamber, to which the air inlet and the fuel rich sustainer feeds through a hot gas valve.
So, yes there is a booster to boost it to higher mach Nos. but that booster is not a separate entity attached as a stage, when launched from air
During ground tests, an additional booster is attached as a first stage to take the exp set up to the desired altitude and speed for realistic testing of SFDR booster ignition just as if it were launched from an aircraft.

I think we talked about this when it was initially planned
Since the SFDR was designed from ground up to be a VLRAAM, the diameter to the missile is actually quite low. If it weren't for those 2 ducted intakes I was ready to believe that the SFDR was slimmer than the Barak 8. Presence of those intakes makes it difficult to believe that the SFDR in its present form can sit inside a Barak 8 VLS. It would've been great if we could. Its about time we get to making UVLS for our ships.
Either way its a great capability booster. Frankly I was expecting a range of around 200-250 km, not 340 km. That surprised me, but its the good kind of surprise.
Oh so that's what nozzle less booster meant. Thank you very much, that was the best explanation I've read so far.
Notice how the DRDO says 1000-1200 sec specific impulse providing 70-340 km in ramjet "on" mode. Surely calculated with the booster and the velocity of the aircraft launching the missile, we should be able to reach ~400 km.
The American ASROC has a range of 22 kms. DRDO's SMART has 50-65 range. Even if its not 650 km as the typo says, I'll gladly take it.
The ASROC carries a Mark 46. What will the SMART carry Shyena light torpedo ?
please read my post when this was tested. I had very clearly stated that we will now have better BMD weapon than what rest of the world has. The A2A version will outrange any such missile inlcuding Meteor by over 100 kms. The co-operative targeting for this missile is being worked on. The ground based system will come with a booster and will be longer in size.
The French have done us a favour by refusing integration of Meteor on Russian platforms. We will now defeat them in this game. I had always maintained that we have far superior propulsion tech in terms of fuel compared to rest of the world. This missile proves it as it has same size as Meteor in A2A mode but far longer range.
I expect French to suddenly become very friendly to us and agree for integration of Meteor on Su-30MKI.

The Specific impulse figures ? I was thinking the same.Something is off here on numbers.
Normally, for a missile/rocket shooting up :
Thrust = (Mass of rocket X Specific Impulse X acceleration due to gravity)
Simplifying that you are left with :
Velocity of exhaust at nozzle = (Specific Impulse X acceleration due to gravity)
Using the Isp figures given calculating velocity gives you an impossibly large number. Impossible because Ramjet engines shouldn't be working at these velocities.
Important thing to remember is that the missile was never intended to fly straight up and not take any maneuvers. Any of those high G turns and low altitude firings should reduce velocities within acceptable limits. Drag increases with increase in velocity.
Also notice how the Isp numbers are between a range(1000-1200 sec) and there is no mention of the environment where it was calculated(sea level, vacuum etc). WTH is that ? Look at the Isp figures that ISRO gives out for its engines, they are highly specific down to 2 decimal numbers with proper mention of tests conditions.
Its almost like DRDO is willfully doing a shoddy job at reporting proper figures with appropriate test parameters.
