The President of India has approved the introduction of a new design for the President's Standard and Colour and naval crest for the Indian Navy, officials said on Monday.
These were unveiled in Visakhapatnam on the occasion of the Navy Day on December 4.
The erstwhile design of the President’s Standard and Colour for the Indian Navy was instituted on September 2017. The design comprised one each horizontal and vertical red bands intersecting at the centre and the National Emblem inserted at their intersection. The National Flag was at the upper left canton adjacent to the staff and a 'golden elephant' was at the lower right canton on the fly side.
This design was inspired from the erstwhile Naval Ensign, the Defence Ministry said in a statement.
The President of India has ''approved the introduction of a new design for the President’s Standard and Colour and Indian Navy Crest for the Indian Navy, which were unveiled at Visakhapatnam on Navy Day,'' it said Resonant to the ongoing ''national endeavour to move away from the colonial past'', the Naval Ensign was amended to a new design that draws inspiration from our history wherein the red horizontal and vertical lines on the white ensign were replaced with a blue octagon with twin golden borders encompassing the National Emblem atop a clear anchor and National Emblem with 'Satyamev Jayate' inscribed on the stock of the anchor, the statement added.
