These vessels will be used for MSA and will not have Anti-Ship missiles and neither AAM's.
Keep this in mind, that they are not being bought for the Navy, so probably they won't have the weapon/sensor suite as per a Navy Missile Corvette.
Primarily activities of PMSA are directed towards ensuring protection of resources of Exclusive Economic Zone (EEZ), Search & Rescue (SAR) operations in the area allocated by International Maritime Organization (IMO), Disaster Management at Sea, protection of Marine Environment, ensuring safety and protecting our fishermen and regulating deep sea fishing activities. Besides this, PMSA has made enormous contribution in preventing smuggling and drug trafficking through sea.
