9 15cm guns, all on the sides? How does that lay out? Or is one turret supposed to be on the centerline?

Also, where is India getting the 40mms and 20mms from? Aren't the usual Indian calibers near that 35mm and 15mm?

The SAE is using 40s and 20s for example....

Hrolf,

In regard to the 150mm you are correct one of the turrets is centerline aft. My fault. And the 40mm and 20mm are to make it more accessible for sale. Same with a main armament of 254mm instead of the regular 250mm of the Indian Navy.
