Sitharaman was elevated to the cabinet rank on Sunday and given the defence portfolio.
A priest held prayers in the defence minister's chamber before she assumed charge.
Senior officials of the ministry were present and she briefly interacted with them after taking over as the minister.
She became the first full-time woman defence minister and the second woman to take charge of the key portfolio. Indira Gandhi, as then Prime Minister, had also held the portfolio in the seventies.
As the Defence Minister, Sitharaman will be a member of the crucial Cabinet Committee on Security whose members include the Prime Minister, the Home Minister, the External Affairs Minister and the Finance Minister.
