More MiG 29K aircraft to be inducted into Navy: Admiral Verma

Its just old deal. Whats noise over it?

Give NLCA year or so before disapproving its operational capability. Mig29k's fire control radar are excellent. Nothing beats them as far as navy's training for carrier operations are concerned.

Interesting!! Can you tell us more about this blackout ?

OT but the growler is capable of causing total radar and communications blackout over an area of 101736 sq. kms (cannot find the source, but will try to).
It can carry 5 EW Jammers including the next generation ALQ-99 jammers. That's quite a lot!

The jamming equipment even on the prowlers was so powerful that the jammers should not have been turned on in the vicinity of any personnel and the cockpit was specially EM wave protected. The growler takes this to the next level.

Nice article here if you want to read more.

Do you even understand what that number means? It means a electronic combat radius of 100 kms. Imagine the amount of power it will need for each EW suit.

Growler carries the same pods as the Prowler, what's the big deal?

ALQ-99 is powered by spinner turbines on the pod, it isn't much power.

For jamming and electronic warfare you have to use a significant amount of power for the suites - or else you cannot defeat enemy radar installations.

The contents of the briefing are not public knowledge, but Kochman only allowed that the power of new surface to air radars stretch the limits of the ALQ-99's transmit range.

Only radar/SAM set-up which was difficult but still within capabilities was the S-400 set-up.

The source of the Prowler's potency is the Eaton/AIL AN/ALQ-99 Tactical Jamming System. The Basic/Excap ALQ-99 is comprised of a Frequency Set-on Receiver set. up to five external jamming pods and a central processor tied into an IBM AYQ-6A central computer. The ALQ-99 is integrated with a General Instrument ALR-42 System Integration Receiver set.

Functionally the ALR-42 SIR is at the top of the chain - it is a sophisticated radar warning receiver which detects and prioritises threat radars (threats) for power managed jamming by the ALQ-99 or the aircraft's defensive ALQ-41 trackbreaker ECM (also supported by the APR-27 SAM launch warning receiver). Power management is a term which refers to the allocation of available jamming power in such a way that the greatest threats receive the most power and are thus most strongly degraded.

Threat parameters are passed by the ALR-42 SIR to the ALQ-99 which locks its set-on receivers on to the designated threats. Unlike conventional RWRs, the set-on receivers can actually remember and analyse the threat signal waveform (employing a Frequency Memory Device and Signal Processor) and provide parameters used by the ALQ-99 central processor to programme the allocated jammer. The ALQ-99's jammers are carried in external 950lb pods each of which carries typically two 2 kW transmitters, a control computer tied to the computer in the parent aircraft and a substantial volume of dedicated electronics (power supplies, exciters, drivers) to support the transmitters. Transmitter power is provided by a ram air generator at the front of the pod with transmitter antennas under the forward ventral pod radome.

The ALQ-99 offers several noise/spot-noise jamming modes (refer TE Sept 88) and may have other capabilities such as false target generation - no doubt a well kept secret. In terms of management, the ALQ-99 can be operated in three primary modes. Automatic, where the SIR detects threats, the computer sorts them and the jammers jam them. Semiautomatic, where the operator selects and controls the jammers; and Manual, where the operators also identify and prioritise threats.

The ALR-42/ALQ-99 provides the ability to jam high power surveillance, acquisition and tracking radars; this capability is supplemented by a Sanders ALQ-92 Communications Jamming System which disrupts GCI communications links, this device was also earlier carried by EKA-3B standoff jammers.

THE ANATOMY OF THE TACJAMMER

Encyclopedia

The AN/ALQ-99 is an airborne electronic warfare system, found on EA-6B and EA-18G military aircraft.
System Description

The ALQ-99 is an airborne integrated jamming system designed and manufactured by EDO Corporation. Receiver equipment and antennas are mounted in a fin-tip pod while jamming transmitters and exciter equipment are located in under-wing pods. The system is capable of intercepting, automatically processing and jamming received radio frequency signals. The system receivers can also be used to detect, identify and direction find those signals, providing Signals intelligence (SIGINT) either automatically or manually.
Platforms


The AN/ALQ-99 is currently mounted on EA-6B Prowler and EA-18G Growler aircraft of the U.S. Navy and, in the case of the EA-6B Prowler only, U.S. Marine Corps.

It has been previously mounted on EF-111A Raven aircraft of the U.S. Air Force. These aircraft were fully retired from service by May 1998.
Versions

AN/ALQ-99E – the version mounted on EF-111A aircraft. It has a 70% commonality with the U.S. Navy's AN/ALQ-99 systems.



The EF-111A Ravens were initially stationed at Mountain Home AFB, Idaho using modified AGS Yellow Squadron's F-111A Aardvarks.
Performance

The AN/ALQ-99 has a maximum power output of 10.8 kW in its older versions and of 6.8 kW in its newer versions. It uses a ram air turbine to supply its own power.
History


The AN/ALQ-99 has been used during the Vietnam War (1972-1973), 1986 American attacks in Libya, 1991 Gulf War, Operation Northern Watch (1992–2003), Operation Southern Watch (1997–2003), 1999 Balkans War, 2003 Second Gulf War, and 2011 Operation Odyssey Dawn. The poor reliability of the ALQ-99 and frequent failures of the Built In self Test (BIT) have caused crew to fly missions with real faults, the ALQ-99 also interferes with the aircraft's AESA radar, reduces the top speed of the aircraft and imposes a high workload on the two man crew.

So, as you can see, the Growler is armed with the same basic technology introduced in the 1970s. Sure it has undergone upgrades and is probably one of the best of it's kind - still it is unreliable and has interference problems with the avionics an radar.
As for covering a 100 km radius cone - that is Raytheon claim - it is true for test conditions and is probably useless for real-life situations - with 6.8 kw power, how much power can you deliver in a sweeping beam to jam ground based radar installations?

Nice video - I would love to see one with weapons load on the Mig-29K.
