An application under the Right to Information Act (RTI) has been filed with the Government of India inquiring about the launch of India's nuclear codes.

Vivek Kumar, deputy secretary at the Prime Minister's Office (PMO) and an Indian Foreign Services (IFS) officer, in a tweet, revealed that he had seen such an RTI application.

Saw an RTI request for nuclear missile launch codes today. July 10, 2015

Kumar denied revealing the identity of the person behind this RTI application but confirmed that the application was indeed real as the statutory fee of Rs 10 had also been deposited.

I will not be revealing the identity of the applicant. It may be misusing someone's name. Also, I am better than that. — Vivek Kumar (@vivx) July 10, 2015

As a protocol, the launch codes of India's nuclear weapons are with the prime minister. Once sworn in, the national security advisor gives a presentation to the PM about the locations of the nuclear warheads and their strength while handing over the launch codes required to activate the weapons if needed.

India has maintained a 'no first use' policy which means that the country will not be the first one to use nuclear weapons against an enemy in case of an untoward incident.

India,which is not a signatory to the non-Proliferation Treaty (NPT) has between 90-110 nuclear weapons while Pakistan has between 100-120 nuclear warheads.

The 5 nuclear weapon states, namely, US, Russia, China, France and the UK have roughly 15,400 nuclear warheads between them.
