History and Making of P17A Ship Project.

The "P-17A Project" refers to a class of "stealth guided missile frigates" being built for the "Indian Navy" under the Indian Ministry of Defence. It is a follow-up to the earlier "Project 17 (Shivalik-class)" frigates and forms part of India's ongoing naval modernization program. Here’s a breakdown of its "making and history":
