ABSTRACT (Continue on reverse if necessary and identify by block number) The U.S. Navy's doctrine "..Prom the Sea" anticipates that future naval confrontations will likely occur in the littoral regions of the world in support of operations ashore. One of the challenges facing naval forces are corvette or light frigate warships incorporating advanced technologies. In this thesis, a review of the historical developments of these limited displacement warships is presented. World War 2 escorts of the Allied forces formed the backbone of many of the navies which formed after the war. Technological improvements have allowed corvettes and light frigates to develop from being ships of limited capabilities to being the "capital ship" for smaller navies. It was determined that while more countries, particularly Pacific Rim countries, are producing warships, the number of producers of technologically advanced weapons and sensors is still primarily limited to the countries of Western Europe. The anti- ship missile is expected to continue as the primary weapon, however, its capabilities are going to increase as higher speeds, lower radar cross sections, and passive seekers are incorporated. 16.

One of the challenges facing naval forces are corvette or light frigate warships incorporating advanced technologies. In this thesis, a review of the historical developments of these limited displacement warships is presented. World War 2 escorts of the Allied forces formed the backbone of many of the navies which formed after the war. Technological improvements have allowed corvettes and light frigates to develop from being ships of limited capabilities to being the "capital ship" for smaller navies. It was determined that while more countries, particularly Pacific Rim countries, are producing warships, the number of producers of technologically advanced weapons and sensors is still primarily limited to the countries of Western Europe. The anti-ship missile is expected to continue as the primary weapon, however, its capabilities are going to increase as higher speeds, lower radar cross sections, and passive seekers are incorporated. 111 TABLE OF CONTENTS I.

Many of the navies formed after World War II acquired "second-hand" warships from the established "mature" navies. The ships which were made available were small compared to the newest ships entering the inventories of the mature fleets. Because of the level of sophistication available at the time, the larger fleets had little to fear from this horizontal proliferation of naval capabilities.
