QRSAM Missile System Achieves Major Milestone

Posted On: 13 NOV 2020 6:34PM by PIB Delhi

Quick Reaction Surface to Air Missile (QRSAM) System has achieved a major milestone by a direct hit on to a Banshee Pilotless target aircraft at medium range & medium altitude.


The missile launch took place from ITR Chandipur on 13th Nov 2020 at 1550 hrs off the Odisha Coast. The missile is propelled by a single stage solid propellant rocket motor and uses all indigenous subsystems. The Missile is canisterised for transportation and launch using a mobile launcher capable of carrying 6 canisterised missiles.


All QRSAM weapon system elements like Battery Multifunction Radar, Battery Surveillance Radar, Battery Command Post Vehicle and Mobile Launcher were deployed in the flight test. The system is capable of detecting and tracking targets on the move and engaging target with short halts. The system is designed to give air defence coverage against strike columns of Indian Army.


The radar tracked the Banshee target from farthest range and missile was launched when target was within kill zone and achieved the direct hit with terminal active homing by RF Seeker guidance. Various DRDO labs DRDL, RCI, LRDE, R&DE(E), IRDE, ITR have participated in the test.


The weapon system elements have been realized through Defence PSUs BEL, BDL and private industry L&T. The missile system is fully indigenous with active RF Seekers, Electro Mechanical Actuation (EMA) systems sourced from various industries. The Radar is four walled Active Phased Array Radar. All range Tracking stations, Radar, EOTs & Telemetry Stations monitored the flight parameters.


Raksha Mantri Shri Rajnath Singh and Secretary DD R&D & Chairman DRDO Dr G Satheesh Reddy congratulated DRDO Scientists for the achievement.

Sskp means what? Is is kill probability?
Length and weight are in the class of B8 actually. Pretty sure DRDO can work on expansion of its kill zone, especially altitude, coz even MALE UAVs in battlefield can be flying over that 6km altitude.
I think we are not at the level of wester or russians when cimes to missile technology.
All of our missiles from this qrsam to agni6 have lesser range w. r. t its mass.

Flight envelope expansion can be done by pushing the weapon to its extreme, that will not only help to certify the system for greater engagement envelope, but also give out the possibile manufacturing issues, which can be learnt from and the quality of production can be improved. Can be done imo.

I don't know, some one with technical knowledge can be shed some light on it.

Single shot kill probability

I had no intention of correcting your belief regarding inferior indian technology

But I will indulge you for once

QRSAM has all the way thrust almost throughout its flight envelope. In addition to that the jet vane control is active throughout the flight envelope , which cuts range to some degree , but allows for excellent manuverability at any point throughout its flight envelope with active thrust on. ( JVC won't work without active thrust )

Long story short the designers went for a dog fighting missile ( at the expense of range ).

Range is not a problem, most of its engagement will be in 10-15km range only.

The altitude will be a problem, as MALE UAVs carrying weapons over battlefield will escape its kill zone.

For a ship , something similar in the class is Barak 1 missiles , but for the ship , it is the lone target out in the sea and it is a point defence system, so having a 5-6 km altitude works , but on lang , QR Sam will be protecting integrated battle groups. And having limited engagement altitude, leaves out the most dangerous thing , the ground attack aircraft and High flying UAVs out of its engagement range.

Once the current lot is tested & deployed, we can always work on the altitude in Mk-2. I'm glad we've ( DRDO + services & MoD) finally embraced the philosophy of incrementalism over exponentialism.That's the way forward.

Why are we going for full through powered missiles like akash & this missile . . .?

Is there any AD tech that can protect against swarm drones.?

@Ashwin

What do you think is the cause , inferiority complex ? Or ignorance ?
Whatever it is it has become a plague lol
Let’s not insult the poster @Hydra . I know he is a fanboy of F15 for which I troll him frequently 😀
But it’s a very common perception that Western and Russian MIC is way more advanced than our nascent domestic counterparts.
We are using Russian and US/European weapons because either what we have/had are inferior to theirs or we don’t have anything at all.
And mind you, we import “a lot”.
I believe it was not that terrible assumption keeping in mind the realities on the ground.

BTW your explanation was very informative and motivating. Kudos to you. Keep it up bro/sir. You have knowledge about these systems so these assumptions look stupid to you but it’s not for laymen like us.
PS: I too thought it’s because Russians using some higher energy density fuel.

AD works in a layered configuration

Why the hell do you you think we are investing in multiple systems like akash, akash ng , mrsam , qrsam , mpdms , vlsrsam , xrsam , spyder , s400 etc


SAMs are basically classified according to slant range and engagement altitude.

we have

1.MANPADS
2.Short range sam
3.ER-SHORADS
4.medium range sam
5.Long range sam
6.Very long range sam

against maneuvering and agile targets using terrain masking flight profile ,
GENERALLY
1.MANPADS will have the highest kill probability under best case scenario

2.Short range sam will have the highest kill probability under best case scenario

3.ER-SHORADS will have the highest kill probability under best case scenario

4.Medium range sam

5.Long range sam

6.Very long range sam

MRSAM lrsam and VLRSAM will be GENERALLY useless against the above targets.

MANPADS SRSAM ERSHORAD are best effective against maneuvering and agile targets flying at low altitudes in order to evade the radar , because of the low engagement range capability , very quick response time , very short kill chain , low escape zone , high maneuvering capability , seeker sensitivity, acquisition and lock on is optimal at low ranges.

my point being you have to select your sam depending on your requirements and conditions .
1.point defense / base defense / area defense
2.terrain to be protected , flat / mountainous / valleys
3.static defense / mobile defense
4.stand alone / networked
5.internal sensors / external sensors
6.integral protection / deterrence

etc

if MRSAM lrsam and VLRSAM comes up against a maneuvering and agile targets flying at medium to high altitudes (a foolish decision in the first place) then the best case scenario for the MRSAM lrsam and VLRSAM will be to force the fighter to dump its weapons and fuel and turn tail.
ie MRSAM lrsam and VLRSAM achieved a MISSION KILL which is as good as a TARGET KILL. But if they manage to get a TARGET KILL then it is a bonus.

the best scenario is when you have all of these networked , integrated and in overlapping mode

1.MANPADS protects against low flying , pop up targets , terrain masking targets

2.SHORT range sam protects against low flying , pop up targets , terrain masking targets , maneuvering targets on weapon delivery run , PGMs , cruise missiles

3.ER-SHORADS forces low flying , pop up targets , terrain masking targets to either abort mission or to fly up into the engagement envelope of MRSAM / lrsam or get killed.

4.medium range sam kills target within their engagement envelop at medium or high altitudes , if the targets have been forced to the kill zone or if the target is unaware of the existence of the said SAMs. however kill probability is low especially against receding targets while high on head on mode.

5.LONG range sam good against bombers, awacs , tankers , and against a flight/group of fighter formations, also good if the fighter pilot falls asleep during flight.
also tries to force targets to descend into lower altitudes to be caught up by MRSAM SRSAM ETC.

6.VERY LONG range sam same above with additional anti ballistic capability.


I have tried to explain a highly complex subject as simply as I could , if you got the overall idea than good for you.

The specific impulse of fuel used by US and Russia is a bit more than Indian ones but that is not a hinderance in any way.

Amd processors used to be a little behind intel processors in speed etc , but does it mean AMD processors are bad or not competative .

Technology is always a work in progress

AMD heat management is terrible. It’s best suitable to be used as room heater in winters.😀

Incorrect, the role of QRSAM or Barak 1 is point defense with a fast reaction. No MALE UAV is entering QRSAMs target envelope without getting intercepted by other long-range SAMs or fighters of IAF. QRSAM is an army specific system for specific use case. Altitude limitations are intentional to have better mobility.
