By the mid 80-ies of XX century, the naval experts of the countries of the West had no doubt that the most advanced class of surface ships in the foreseeable future will remain the frigates. These versatile ships-rocket carriers have been very numerous in the seas and oceans under the flags of different countries at the time, swam at least 350 frigates, and their “population” continued to rise steadily. They actually replaced the cruisers and destroyers in most countries of the world, becoming the largest combat units in their fleets. Of course, the attitude towards them has changed: the design and construction of the frigate now began to approach more carefully, trying to avoid the rush and the use of untested solutions.
