• To mark its the 91st anniversary of Indian Air Force, a new IAF ensign will be unveiled on the occasion of Indian Air Force Day.

• The new ensign will include the Air Force Crest in the top right corner of the Ensign, towards the fly side.
• During the British era, Indian Air Force was known as Royal Indian Air Force.
• Its ensign comprised of the Union Jack in the upper left canton and the RIAF roundel (Red, White & Blue) on the fly side.
• Post-Independence, the Indian Air Force ensign was created by replacing the Union Jack with the Indian tricolour and the RAF roundels with the IAF tri-colour roundel in the lower right canton.
• The IAF Crest has the national symbol, the Ashoka lion on the top with the words “Satyameva Jayate" in Devanagari below it.
• Below the Ashoka lion is a Himalayan eagle with its wings spread, denoting the fighting qualities of the IAF.
• A ring in light blue colour encircles the Himalayan eagle with the words “Indian Air Force".
• The motto of the IAF "Nabha Sparsham Deeptam" is inscribed below the Himalayan eagle in golden Devanagari.
• The IAF motto has been taken from verse 24, Chapter 11 of the Bhagavad Gita and means "Radiant Thou Touchest Heaven" or in other words "Touching the sky with Glory".
