The defence minister landed at the Chabua Air Force Station in Upper Assam and then took a Mi-17 helicopter and went to Pasighat in Arunachal Pradesh.
At Pasighat Advanced Landing Ground, two Sukhoi Su-30 MKI fighter jets took off and then a C-130J Super Hercules transport aircraft landed, from which Garud Commandos simulated taking over of the base.
Ms Sitharaman was also briefed about the uploading of rockets in a Mi gunship, Air Force sources said.
While the Sukhois dropped three 1,000 pounder bombs, the Mi 17 gunships fired rockets.
On returning to the Chabua base, Ms Sitharaman witnessed bombs being loaded into the Sukhoi SU-30 MKIs.
Over the last few years, the Air Force has operationalised several Advanced Landing Grounds in Arunachal Pradesh, close to the China border.
