The "Raftaar" or "Speed" squad of 600 policewomen will ride in pairs through the streets on state-of-art motorbikes, equipped with guns, pepper sprays and body cameras.
"Basically it is a robust street criminal containment strategy," Delhi police spokesman Dependra Pathak told the Hindustan Times.
"There will be a specifically designed helmets with ear-pieces. The pillion will carry a weapon like an AK-47 rifle and the rider carrying a 9 mm pistol ... They will have all the accessories to make them effective on the ground."
An October poll by the Thomson Reuters Foundation found Delhi, along with Brazil's Sao Paulo, was the world's worst megacity for sex crimes against women, earning it the unsavoury title of India's "rape capital".
Reports of violence against women in Delhi have almost doubled since 2012, with 11,588 crimes, such as kidnapping and assault, recorded up to Nov. 15 this year, police data shows.
Public awareness of violence against women in Delhi, particularly sex attacks, has surged since the fatal gang-rape of a 23-year-old student on a bus in December 2012.
Indian authorities enacted stricter punishments for gender crimes, and set up a 24-hour women's helpline, fast-track courts for rape cases and a fund to finance crisis centres for victims.
Women's desks in many of Delhi's police stations have been established, thousands of police received gender sensitisation classes, and Delhi has more patrols, surveillance and checkpoints at night.
But research by Human Rights Watch (HRW) this month found that India's criminal justice system continues to fail victims.
HRW said survivors of sex crimes often suffered humiliation at police stations and hospitals, police were frequently unwilling to register their complaints and victims and witnesses received little protection.
