According to Hindustan Times, India plans to discuss weaponisation of the Guardian unmanned aerial vehicle (UAV) with US secretary of state Rex Tillerson on October 25, during his visit to New Delhi as part of a five-nation tour of the subcontinent.

The US had formally submitted its “pricing and availability” proposal for the sale of 22 Guardian UAVs to India before defence secretary James Mattis’ visit last month. India hopes to use the high-altitude long-endurance drone to protect its 7,000-km-long coastline from potential infiltrators.

Tillerson is slated to arrive in New Delhi on Tuesday evening. He will meet Indian Prime Minister Narendra Modi, external affairs minister Sushma Swaraj and national security advisor Ajit Doval the next day, before flying to Pakistan for a short visit. He will not spend the night in Islamabad due to security reasons.

Diplomatic sources in New Delhi and Washington told HT that Tillerson will review bilateral ties, besides focusing on 'terrorism in Pakistan'-Afghanistan region, bilateral synergy in the Indo-Pacific zone and security concerns over North Korea.

While New Delhi remained tight-lipped on the defence acquisition, senior officials said the 22 UAVs – priced at around $3 billion – would be more cost-effective if they were weaponised.

The weaponised version of the Guardian is called the Sea Avenger, and it comes with a top-of-the-line synthetic aperture radar and an electro-optical targeting system for firing Hellfire missiles and laser-guided bombs.

Tillerson and Doval are expected to discuss several global issues, including the North Korean nuclear threat; terrorism in Pakistan-Afghanistan; Qatar-Saudi Arabia discord; Indo-Pacific enhanced bilateral naval cooperation; and the future of the Islamic State.

The two sides will firm up their commitment to reconstructing and stabilising Afghanistan, and look at ways to bring the Taliban to the negotiating table. According to reports, India will also urge Tillerson to put pressure on 'Pakistan to act against terror groups.'

“We are looking forward to Tillerson’s visit, and plan to take our bilateral relationship on the path defined by him in his speech at Washington’s Centre for Strategic and International Studies on October 18,” said a senior South Block official.
