India Almost Flew the E-2 Hawkeye Carrier-Based AEW&C in 2000, Now China's KJ-600 Soars

The development of carrier-based airborne early warning and control (AEW&C) platforms underscores the growing significance of these assets for modern naval forces.

China's KJ-600 program highlights this, but it's not the first time an Asian nation seriously considered this capability. The Indian Navy, years before the KJ-600, nearly made a deal that would have profoundly changed its carrier operations.

India's Hawkeye Exploration​

In the early 2000s, India eyed the Northrop Grumman E-2 Hawkeye for its upcoming Indigenous Aircraft Carrier (IAC), a planned 65,000-ton carrier. The goal was to acquire six E-2s for both the INS Vikramaditya and its new domestically built carrier.

The E-2 Hawkeye is well-regarded, offering significant command and control capabilities and long-range aerial surveillance.

However, the Indian Navy quickly ran into obstacles:

• Carrier Compatibility: India's planned carriers lacked catapult launch systems (CATOBAR), vital for operating heavier aircraft like the E-2.
• Performance Limitations: Reports suggested the Hawkeye struggled in specific lighting conditions, dramatically hampering its endurance.

By 2005, the Indian Navy walked away from the deal. Limitations coupled with possible emerging alternatives likely drove that decision.

China's Airborne Solution - The KJ-600​

Meanwhile, China forged ahead with its domestic AEW&C solution, the KJ-600. This high-wing, twin-propeller aircraft carries a large dorsal radome suggesting substantial radar power.

Built explicitly for the PLAN's Type 003 carriers (which do use CATOBAR launch systems), the KJ-600 promises significantly enhanced situational awareness for Chinese naval operations.

Its development speaks to the growing role AEW&C aircraft play in naval power projection, a role China clearly wants to maximize.

The Future of Asian Carrier-Based AEW&C​

While the Indian Navy ultimately took a different route (opting for smaller helicopter-based AEW systems), it's probable they'll explore fixed-wing carrier solutions in the future.

The benefits of an aircraft like the KJ-600 – extended range, powerful radar, and superior command and control functions – are undeniable.

Both China and India's interest in this area emphasizes the shift in regional maritime security. AEW&C platforms are becoming central to establishing dominance within an increasingly contested operational theater.

Japan does...

Yeah Japan does. First deliveries of 14 MV-22 aircraft began in 2020. No perfecture in Japan want to allow basing of the aircraft there due to its dismal safety history. So much was the opposition so that finally Japanese Govt had to decide to deploy it only aboard the Izumo helicopter class destroyers. Now, following the crash of the USAF CV-22 off Yakushima in Nov 2023, Japan has suspended indefinitely all flights of its 14 CV-22's !!

No, it was a reasonably serious consideration. The US even conducted a bunch of demonstrations in the US for Indian officers. The Navy planned to acquire 6 E-2s, of which 2-3 would be deployed on a future CATOBAR carrier, with the rest being deployed to shore bases. That idea just died a death in the late 2000s after the IAF ordered the A-50s and said that A-50s would be available for naval use if needed. Of course, the second order for two A-50s got delayed later on, and the Navy hasn't had that sustained capability for some time now.

THats why I said, its a fantasy and not a real plan. A-50's were acquired by IAF in 2003. In 2005, the Navy decided against acquiring E-2D's. Is close to 2 decades now!! if it was anything serious, things would have moved by now for alternatives ! Nothing new, classic Indian lethargy, till the backside will be on fire !!

There have even been some noises by some Japanese officers who want to sell their V-22s back to the US or exchange them for other helicopters with the US.

It won't be nuclear propulsion this was confirmed quite some time back becuz BARC demanded 15 years min to work on nuclear reactor capable of 65,000 tonne AC.

That confirmation was given on the belief that INS Vishal would have to enter service in the late 2030s to relieve Vikramaditya, which would have to leave service around 2040 in case we had Vishal following up on Vikrant. Now, however, with the Navy going ahead with a second Vikrant-class carrier, Vikramaditya can go in a state of reduced readiness occasionally, or can be given a LIFEX to extend her life into the late 2040s (let's take 2048 for 35 years of Indian service).

That extra decade that now exists should be plenty of time for BARC to finish work on their reactor. I am assuming work has already been started, so even if we have the reactor poised for completion by 2040 or so, we could design and start work on a 65,000 to 75,000 ton nuclear carrier by 2037-38, which would allow said reactor to be installed by 2042-43, and the carrier could then enter service by 2048-50.

The Navy made do with the Ka-31s because of the IAF's promise to provide A-50s if need be, which has largely remained unfulfilled thanks to only 3 A-50s being available. Now, with another 12 AWACS planned, one would hope atleast 2 or 3 would be available for naval reconnaissance use when needed. That said, when we do go for a CATOBAR IAC-III, we would be needing a carrier-based AWACS, and the Ka-31 simply isn't going to cut it (even if you assume the airframes are still around for another 20-25 years).

I would not be surprised with this development.

No, it isn't as easy as it sounds. A massive flat radar sticking out of the bottom of an aircraft is a massive source of drag for an aircraft, which would impact flight conditions quite a bit.

Secondly, you would have to stow the radar in a position such that it wouldn't interfere with the folding undercarriage (the entire swing of the landing gears) or the tailhook, get any form of interfere from the engines, and would be flat enough so as to not hit the deck when the aircraft was taking off or landing.

The Ka-31 avoids these by having a vertically-lowering landing gear, and, since it is a helicopter, it takes off and lands in a flat manner rather than an incline such as an aircraft.

All of those things would leave little space for you to actually mount that radar under a fixed-wing aircraft.

Not when it is made aerodynamic, we see lot of bulges in the fuselage of AWACS and SIGINT planes, you can’t make any jets with 0 Drag, it is all give and take based on benefits.

Sirji, why do helicopter carriers need ski jump ? Most are around 200mtrs which is very very tight for aircraft to land or take off.

Even F35B does short take off for obvious reasons, when it is fitted with full payload though it can takeoff or land vertically
