For the first time since Independence, many major reforms were rolled out in India's defence sector and it has more transparency and trust than ever before, Prime Minister Narendra Modi said on Friday.

After dedicating seven new state-run defence firms replacing the Ordnance Factory Board, the prime minister said a single-window system has been put in place instead of stagnant policies to develop India as a major producer of defence equipment.

"Under the self-reliant India campaign, the country's goal is to make India the world's biggest military power on its own and development of modern military industry in India," Modi said.

"In the last seven years, the country has worked to carry forward this resolve with the mantra of 'Make in India'," he added.

In his video address at the event, Modi said that as India enters 75 years of Independence, projects are being completed that were stuck for a long time.

"Today, there is more transparency, trust, and technology driven approach in the defence sector of the country than ever before. For the first time after Independence, so many major reforms are happening in our defence sector. Instead of stagnant policies, a single-window system has been put in place," Modi said.

After Independence, there was need to upgrade ordnance factories, adopt new-age technologies, but it didn't get much attention, he said.

The prime minister said that 41 Ordinance factories are being converted into seven corporate entities, as a measure to improve our self-reliance and defence preparedness.

India is taking new resolutions to build a new future, he added.

Defence Minister Rajnath Singh and representatives from the defence industry associations were present on the occasion.

The government had decided to replace the over 200-year-old Ordnance Factory Board into seven fully entities to improve self-reliance in the country's defence preparedness.

The seven new defence companies that have been incorporated are Munitions India Limited (MIL), Armoured Vehicles Nigam Limited (AVANI), Advanced Weapons and Equipment India Limited (AWE India), Troop Comforts Limited (TCL), Yantra India Limited (YIL), India Optel Limited (IOL) and Gliders India Limited (GIL), the PMO said.
