In 1941 Bharat approached Great Britain with an offer to be allowed to built a series of trade protection light carriers being counted againts the capital ship quota allowed by the ABUSE Treaty. Great Britain refused this initial approach but countered by allowing Bharat to build a Flying Deck Cruiser instead on the same terms. Bharat knew the dangers involved in the construction of a Flying Deck Cruiser but it was the only legal way being allowed to increase the number of aircraft carrying ships available so they finally relented and keel was laid down late in 1942. The flying deck extend to close to 140m with a sponson to port and flight deck slightly angled. Catapults are mandatory to launch aircrafts, barriers and arresters will be in place to help iwth landings. The raised turret and the bridge are slightly on the opposite direction of the angled deck to compensate for the weight of the flight deck.
