so ISAR deletion will mean we cannot classify a ship type quickly or detect periscopes. SAR deletion to protect the munna's land based assets.
both deletions are to increase the comfort factor of the munna as well as make sure khan always has the best kit.

I sincerely hope you're right, Mort, or else a Scorpene will appear as 2 pixels.

^^^I think you're confusing the towed sonar with radar. What the USN version is capable of is periscope detection with the radar, hence the use of SAR & ISAR.

Operating in I/J band, the Sea Dragon radar has a system weight of 260kg. Unit cost is around US$2.8 million, and NIIS claims it is more versatile than the US AN/APS-137, having an air-air detection capability against a sea-clutter background, as well as both synthetic aperture radar (SAR) and inverse SAR (ISAR) target classification modes. Other functions include long-range detection of surface targets in high sea states in jamming and precipitation environments; detection of small targets and emergency beacons in high sea states; navigation; adverse weather look-through and threat evaluation; plus target acquisition and tracking (range, heading and velocity)

From what I have read they are not removing the SAR/ISAR modes - just degrading them for a "monkey" version that is useless for littoral/overland applications. Since the limitations are enforced flexibly through software the periscope search feature will be left alone and should work fine.

Degrading SAR precision to greater than 3 foot renders it irrelevant for overland targets without severely degrading it for maritime use (ships are much larger than AFV/trucks). Similarly they are removing the Ultra High Resolution (UHR) ISAR modes; presumably some ISAR capability will be retained for manual NCTR. With the full precision modes those radars can tell you which ship got hit where as well as what damaged was caused, all at standoff ranges. IN aircraft won't be capable of that kind of resolutions which is fine I guess.

US is ensuring through technological means that the P-8I remains a purely naval asset. i.e. No sudden appearance of the P-8I near Punjab border acting as a mini-JSTARS cuing PGMs. Which is fine so far as the IN is concerned. The other CNI "removals" are probably because of the Indian middle finger to CISMOA and again no great loss.

My view is that the P-8I is not significantly shortchanged in its advertised role for the IN - LRMP/ASW.

Air to air mode is intriguing. Useful to have no doubt but I am having a hard time coming up with use cases where paying extra for it is worth it for an LRMP aircraft. Periodic air scan for self defense when in the suspected vicinity of enemy carrier based aviation? Search for UAV? ASW Helo?

pls see my post in the indian missiles thread. a wild theory could be we are planning a initial bastion in the deep water trench area that lies along the eastern rim of the A&N island chain and extends further down past sumatra.

this is directly within supporting distance of IAF and IN bases in the islands and a short ride from the eastern coast main sub base (vizag or rambilli)

it would not be a closed bastion but more a open challenge bastion like presumably the waters around murmansk or pearl harbour are. as Mithunda would say:

"kisi mai ka lal ke gaand mein dum hai, ki yaha aa ke kuch kar sakey?"

They were picked up by a SAR helicopter shortly thereafter and transferred to the military hospital in Gwalior.

There was so much R&Dh over why our SAR equipped aircraft are incapable of picking up wreckages in the Himalayas or YSR's helicopter. Well - here is one success & a crucial one at that (the pilots needed to be found fairly quickly in case they were injured).

Sir, link is not working.

"The necessary mission systems and components, including the dummy AAAU (Active Antena Array Unit) are successfully fitted on board Embraer EMB 145I aircraft,"
^^^^

The other mission systems will then be integrated on to the aircraft, and mission system flight trials are likely to commence from November.

India’s eye-in-the-sky AEW&C platform (EMB-145I) is scheduled for an official touchdown this July. Sources say that the platform would first arrive at Jamnagar Air Base enroute to its destination in Bangalore for system integration. The plane had its first official flight on December 7 (2011), in Brazil.

NEW DELHI: With Pakistan stealing a swift march in the "eyes in the sky" arena and China already way ahead, India is now going to launch its own full-blown futuristic AWACS (airborne warning and control system) programme.

"Clearances are underway" to initially develop two AWACS aircraft, with four more to follow at a later stage, under the new `AWACS-India' project to be executed by DRDO and its Bangalore-based Centre for Air Borne Systems (CABS).

"Under it, 360-degree AESA (active electronically scanned array) radars will be mounted on large aircraft like IL-76, Boeing or Airbus," said a DRDO source.

Potent force-multipliers like AWACS or AEW&C (airborne early warning and control) systems have changed the entire nature of air warfare because they can detect incoming aerial threats, ranging from fighters to cruise missiles, much before ground-based radars.

They also serve to direct air defence fighters during combat operations with enemy jets and also help in tracking troop build-ups.

Pakistan already has four Swedish Saab-2000 AEW&C aircraft, with four more Chinese ZDK-03 AWACS in the pipeline. China has around 20 AWACS, a mix of new and old systems, say sources.

But IAF has only three Phalcon AWACS mounted on IL-76 aircraft, under the $1.1 billion tripartite agreement among India, Israel and Russia finalized in 2004, despite being confronted with two potentially hostile fronts.

The case for two additional "follow-on" Phalcon AWACS, with a range of over 400-km and 360-degree coverage like the first three, has run into some rough weather due to sharp cost escalation.

Moreover, DRDO's ongoing mini-AWACS project, under which indigenous AEW&C systems are to be mounted on three Embraer-145 jets obtained from Brazil for $210-million, has also slipped after being approved in October, 2004, at a cost of Rs 1,800 crore.

DRDO, however, contends the project is now on track. "CABS will get the first Embraer, modified with antenna units and other structures mounted on its fuselage, in July," said an official.

"All electronic systems, with a normal radar range of 250-km and a 240-degree coverage, will then be integrated. The first flight should take place in early-2013. The project completion date is April 2014," said an official.

IAF is awaiting the completion of the mini-AWACS project as well as the launch of the larger 'AWACS-India' programme with crossed fingers. AWACS also constitute a crucial constituent of its IACCS (integrated air command and control system) programme, the fully-automated network being set up to integrate the wide array of military radars with each other as well as with civilian radars to plug surveillance gaps in Indian airspace.
