The formal induction ceremony of the fleet had taken place at Ambala on September 10 last.
A second batch of three Rafale jets arrived in India on November 3, while a third batch of three more jets joined the IAF on January 27.
The sources said the second Rafale squadron being raised at the next main operating base (MOB) at Hasimara in mid-April this year. India is expected to get more Rafale jets from France in the next couple of months.
A squadron comprises around 18 aircraft.
The Rafale jets are India’s first major acquisition of fighter planes in 23 years after the Sukhoi jets were imported from Russia.
The Rafale jets are capable of carrying a range of potent weapons. European missile maker MBDA’s Meteor beyond visual range air-to-air missile, Scalp cruise missile and MICA weapons system will be the mainstay of the weapons package of the Rafale jets.
The IAF is also procuring a new generation medium-range modular air-to-ground weapon system Hammer to integrate with the Rafale jets.
Hammer (Highly Agile Modular Munition Extended Range) is a precision-guided missile developed by French defence major Safran.
The missile was originally designed and manufactured for the French Air Force and Navy.
Meteor is the next generation of BVR air-to-air missile (BVRAAM) designed to revolutionise air-to-air combat. The weapon has been developed by MBDA to combat common threats facing the UK, Germany, Italy, France, Spain and Sweden.
