Despite this, the company's marketers apparently saw the F-Type's critical and financial success and deemed further investment into a new XK superfluous."The F-Type was never meant to kill the XK," says the Jaguar designer.

HAL could have to develop an entirely new nose section to fit the ELM-2052 onto the IS aircraft, which make up the bulk of India’s Jaguar fleet and the majority of the aircraft slated for the DARIN III upgrade package.

This is where Elta's scalable design could really shine.

Unfortunately, the DARIN III saga, as well as a separate and equally sluggish push to replace the Jaguars’ engines, seems reflective of the Indian Air Force’s modernization efforts.

In January 2017, the country’s Minister of Defense, Manohar Parrikar, announced plans to sign a deal to license produce up to 200 single-engine fighter jets by 2021 at an estimated cost of approximately $45 million apiece.

Depending on how extensive this upgrade program becomes, it could be a significant boon for the Indian Air Force, which has struggled with modernizing its diverse fleets of fighter and multi-role jets. Suvarna Raju, chairman of the state-owned Hindustan Aeronautics, Limited (HAL), made the announcement on Aug. HAL would not say what radar it used, but it is reportedly the Israeli Elta ELM-2052, which that company reportedly agreed to supply in 2015 for both the Jaguar and Indian-designed Tejas fighter jet.

HAL said the new radar alone could give the nearly 40-year old Jaguars, which it built under license from the Anglo-French consortium SEPECAT, at least another decade of service at life.

Elta boasts that it can size the ELM-2052's antenna to fit where ever it needs to go, including in the tight confines of the Jaguar's nose radome.

The Indian radar installation also shows important progress on the broader and long-running Display Attack Ranging Inertial Navigation III (DARIN III) upgrade program for the Jaguars, which began in 2009.

The report goes on to say that a new XK would be assembled in tandem with the next F-Type at Castle Bromwich and sit on an updated version of the current F-Type's platform.

It is also said that Jaguar's Ingenium range of four and six-cylinder engines will be used, likely coupled with some kind of electric motor if their goal of offering an electrified option on every model they sell by 2020 is to be realized.

It’s is not clear how many of the Jaguars will ultimately receive the AESA radar update, either.
