Should it be build?

With the expected refit of the Akbars one of the concerns of the Olf Guru are being taken care off (something to face the Italian Super-Cruisers). But what about heavy escorts for the carriers? it started as an enlarged Vadadora and ended like this (kinda of a slower Radiance with more armor and range). India is really weak in heavy cruisers (2 only in inventory after the sale of two to Mexico in 1936) let me know if feasible. They are expected to either escort the Val or be used for independent operation.

The Old Guru noticed an important detail; not enough range to support the carriers. He gave me some ideas to remedy that so a redesign is in order. I guess this ship will be another of the "planned but not build" ships.

I think I still qualify as "middle-aged", actually...
