Congrats to Israel for developing such a weapon. And to Indians for able to operate the missile.

You should tell this to the Israelis, because those poor fellows seem to be under the impression that it was jointly developed by India and Israel. Little do they know that they made it solely by themselves:

Israel-Indian missile system Barak 8 carries out successful trial in Indian Ocean - Israel News - Jerusalem Post

The project has been in joint Israeli and Indian development in recent years, and is officially due to become operational in both navies within one to two years, he said.

BREAKING: LR-SAM Successfully Tested From INS Kolkata


Livefist can confirm that the first test of the Indo-Israeli Long Range SAM (LR-SAM) was successfully conducted earlier this evening in the Arabian Sea between Mumbai and Goa. The second test will be conducted tomorrow morning. The LR-SAM was testfired last month from an Israel Navy corvette. Photos and videos of today's & tomorrow's tests shortly.

fullfoolguy is PDF's pathological troll.

 

[#hydra#]

sometimes a silent nod is enough response what else you want from people? come and troll you over hygiene and inability to keep little one under the zips? thus spoiling every other thread?

Trolling is the lifline of PDF,there is no fun in reading PDF without them.there are instances were trollers used really bad words & abusive languages,it not acceptable.

These Surface to Air Missiles are fitted onboard the Kolkata Class Destroyers and would also be fitted on all future major warships of the Indian Navy. This missile along with the MF STAR would provide these ships the capability to neutralize aerial threats at extended ranges.



++ My opinion on barak 8 challenges (pls bear its a maxi post)

Next would be the Barak 8 ER version or extended range with one more stage probably a booster stage.. I am expecting it perhaps to reach 150 km minimum with outer peripheral reach or max reach of 170 odd kms

It would be interesting to see how soon the ER version comes out and whats the length of the extended section. Significantly, if they limit the speed to present levels of Barak 8, the fuel burn out per second and requisite thrust may optimally boost it to 150-170 km range over flightpath.

In case, they increase the fuel burnout and use the higher thrust momentum to accelerate the missile forward and increase its speed of interception then the new extended range may fall between 130-150 km

The greatest challenge now will be to see that new ER does not get too big in length, weight and can replace 8 Barak 8s with say 6 Barak 8 ER cells. This makes me to believe, they would choose the first option of not increasing speed but rather the flight time for the optimum 150-170 km range

Interestingly MFSTAR 2248 AESA may be be insufficient for Barak 8 ER for aircraft engagement but the low flying sea skimming missile characteristics needs a bit upgrade IMHO

A stealth fighter or a LO fighter carrying a sea skimmed AshM will create detection issues and perhaps will be more reasonable to assume detection at around 150-180 km and thus the barak 8 ER engagement will be closer to 60-100 kms (same as Barak 8 present model). Similarly, a sea skimming missile detection range at 25 kms will again force a more judicious use of Barak 8 over Barak 8 ER. BTW the mast of Kolkata is higher and hence the radar detection of sea skimming is more in the range of 35-40km.

However, the present 2248 is optimized for Barak 8 but IMHO, the AESA radar itself will limit the optimum potential of the system with both tracking of LO jets at low altitude and sea skimming missile detection

Now consider a hypothetical scenario

• An AESA radar which enables our ships to detect LO aircraft at low altitude around 150 km (assuming to be flying at say Mach 2 (2450 km/hr or 40.833~41 km/minute). (150km being 60% of high flying aircraft detection and due to higher mast).
• The assumption is that detection to authorisation of hostile intent shootdown is assumed to be minimum of 1 minute
• In that 1 minute the LO aircraft flies further towards IN ship to ~ 110 km range
• At the end of 1 minute Barak 8 is fired (standard/ER anyone)
• Assuming Barak 8 speed as 2 mach same as incoming aircraft so it travels 41 km per minute
• after 1 minute Barak 8 has travel 41 km from the ship and hostile aircraft has travelled further 41 km from previous 110 km and is now at 68 km approx. The distance between the two now is 27 km
• With each travelling around 0.68 km per second, the engagement will happen in approx 21 seconds about 41+14=55 km from the ship (41km already traveled and 14km traveled in 21 second)
• End to end calculation is as under
  • Detection at T0 = 150 km
  • Detection, Warning, Authorization of shoot down and firing = 1 minute, hostile at 110 km
  • Engagement in 1 minute 20 seconds from T0 or 80 seconds at 55 km from the ship
• Assume further a sea skimming missile is fired just before the hostile is destroyed.
  • Detection of sea skimmed missile at 40km the new T0 (assuming the missile is already now in its supersonic speed when detected)
  • Immediately Barak 8 is fired time lapsed 15 seconds
  • Sea skimmer assume again Mach 3 (Brahmos is mach 2.8) travelling at 3375 km/hr or 56.25 km per min or 0.9375km/sec
  • So in 15 seconds before barak 8 is fired, the sea skimmer missile travels 14 km inwards and is now 26km away from the ship
  • Barak 8 engages the hostile in approx 15 seconds where barak 8 travels 10.88 km whereas the hostile at mach 3 travels inwards by approx 15 km and is shot down
  • Implies the barak8 shot down the missile at ~11km from the ship
• End to end calculation
  • Detection at new To = 40km
  • Detection, Warning, Authorization of shoot down and firing = 15 seconds and hostile is now at 26km from ship
  • Engagement in 15+15 = 30 seconds from T0 at 11 km from the ship

The above is a hypothetical example and variables may change the reaction time smaller.
In the scenario mentioned, the efficacy of Barak8 itself for supersonic targets is enough and even Barak8 standard type is not using the full extent of its range. It can use the same if the hostile aircraft and missiles travels at speed mentioned below

View attachment 283662

I am not even considering that aircraft and hostile missile may exhibit high G turns and try to avoid interception making reaction time smaller and more closer to ship


Thus, here based on the above approximate guesstimation, the 2248 radar detection for LO targets will limits the performance to the Barak 8 standard version for higher speed hostiles (aircraft LO types lower altitude and engagement distance). The same is also seen for sea skimming missiles detection (i considered upto hypersonic 5 mach)

The extended version or Barak 8 ER will need LO aircraft at low altitude detection in much excess of present assumed 150 km but rather the 250km for standard LO birds and other higher altitude detection at more of 350-400km range

@Vauban @Abingdonboy @anant_s @AUSTERLITZ @MilSpec and others
Pls correct me if i am wrong in concluding the limitation of 2248 for LO aircraft low altitude flying interception for barak 8 standard version and for detecting sea skimming missiles at 40 km implying the Barak8 is never used to its full potential.
The pinpoint interception is fine but design for longer range and effectively not able to due to limitation of system detection is what i am trying to point out.

BTW i dont know what other option we have other than perhaps getting IAI help in increasing 2248 range for LO detection

Excellent post my friend, the sensor (EL/M-2248) was always going to be the limiting factor in employing the BARAK-8's (and ER's) considerable range.

There are a few things to consider though
1) Through overlapping sensor employment and data-linking (now the IN has its own sat specifically for this role) of multiple assets (AEW and other warships) it is possible for the detection issues to be addressed.
2) Adding to the above point the BARAK-8's own targetting ability (onboard seekers) are perhaps the most advanced in service and with its LOAL ability the threat posed by "blindspots" can be severely mitigated.


That said, the EL/M-2248 MF-STAR remains one of the most powerful sensors fitted to any warship today and its tracking and threat classification abilities are second to none. I'm sure that IAI and the IN will be further refining this system for years to come.

Pls correct me if i am wrong in concluding the limitation of 2248

In this whole scenario you have considered the barak 8 speed to be 2 mach and radar at 250 km........which is also a deciding factor in distance of engagement from ship

If you have time considering speed of Barak 8 and rader at higher post the result here

This system (all components) share informations with other configured vessels and assets, and thereby allowing one missile system of Barak 8 to defend multiple vessels and assets ( gas field and so on )
