India stops negotiations with Russia for 10 Ka-31
India has indefinitely put on hold negotiations with Russia for the purchase of 10 Ka-31 air surveillance helicopters. These helicopters were to operate on the aircraft carrier INS Vikrant, which is scheduled to enter service in July 2022.
Indefinite pause
In May 2019, India was entering into negotiations with Russia to purchase Ka-31 Airborne Early Warning (AEW) helicopters. These negotiations were halted due to the COVID pandemic, which meant that the lead time was too long and the price per helicopter too high. Discussions resumed in February 2022, but these negotiations have now stalled, according to DefenseNews, which cites an anonymous source within the Indian Ministry of Defence. According to this source, India has suspended the negotiations due to uncertainties regarding the construction of the helicopters but also problems related to payment. It is also possible that India has been pressured by other countries to reduce financial contributions from Russia following the war in Ukraine.
These helicopters are in high demand by the Indian Navy as they are to be used as part of the air group of the aircraft carrier INS Vikrant. This aircraft carrier (of the STOBAR type) is currently undergoing its final trials before its scheduled entry into service in July this year.
The helicopter eye of the fleet
The Ka-31 is based on the structure of the Ka-29TB assault helicopter. Its mission is long-range detection of naval and air threats. Developed from 1985 by Kamov, its entry into service was postponed 10 years later following the fall of the USSR.
This counter-rotating helicopter is equipped with an E-801M Oko radar (or E-version for export) that deploys as a large rectangle under the helicopter, as shown on the cover photo. In case of emergency, it can drop the antenna with an explosive charge. To maximise the effectiveness of the radar, the landing gear is retractable and the helicopter is equipped with the SAU-37D automatic flight control system (to stabilise the helicopter). Its detection range is estimated at 150 km for aircraft and 250 km for small ships. It has no internal operator (only a pilot and a co-pilot) and therefore transmits the information it gathers to the mother ship via a secure link. The range of this link is approximately 150 km.
In terms of speed and range, the Ka-31 can fly at a maximum of 250 km/h, has an endurance of 2.5 hours and a maximum range of 600 km. When the radar is deployed, the helicopter patrols at an altitude of about 3.5 km at a maximum speed of 100 km/h.
The Indian Ka-31
Currently, the Indian Navy already operates 14 Ka-31s:
4 Ka-31s ordered in 1999 and delivered in 2003 for $92 million
5 Ka-31s ordered in 2001 and delivered between 2003 and 2004 for $108 million
5 Ka-31s ordered in 2009 and delivered in 2013 for $198 million
For the moment, there are very few helicopters available in an AEW version; the Sea King AEW is getting too old and the Chinese Z-18J cannot be chosen for geopolitical reasons (tensions between China and India). Thus, should India choose to replace this order of 10 Ka-31s, it would only be left with the EH-101 AEW or with prospecting for the development of an AEW version from helicopter manufacturers. If the second option is chosen, it will take some time and the Indian Navy will have a capability gap in its airborne early warning elements. (DeepL)
