In 1977, the risk of the nuclear-powered strike cruiser csgn, which was planned to be equipped with the Aegis system, was too high due to the soaring tonnage and cost.

Therefore, the U.S. Navy proposed a high-low combination plan, intending to use the remaining 1000 tons of weight surplus of the highly successful Spruance-class destroyer hull to modify it into a low-end traditional power Aegis ship. This plan is called DDG47.

Numbering continues after the last Farragut-class destroyer.

The U.S. Navy Ship Engineering Center, which previously designed the Spruance-class hull, continues to plan all the changes needed to place the Aegis system on this hull.

Compared with the Sri Lankan class, the design changes of the ddg47 include: redesigning the superstructure to accommodate the spy1a phased array radar. In order to reduce the weight of the superstructure, its superstructure uses a large amount of lightweight aluminum alloy.

In order to compensate for the weight of the superstructure, increase the maximum displacement and center of gravity rise margin, and improve the recovery in the event of damage, the height of the main transverse bulkhead of the DDG47 is extended from the original No. 01 deck of the Si-class to the higher-level 47 deck. , which increases the upper limit of the design displacement of the DDG8800 hull from the Sri Lankan class's 9700 tons to tons.

Due to the increase in draft caused by the increase in weight, a 47m high wave board was added to the bow of the DDG1.1, making the hull length 1.2m longer than that of the Si class.

Budgeting:

1977年度，美国海军提出首舰ddg47的5.1亿美元建造预算，并于1978年9月22日与英格尔斯船厂签署首舰的细部设计与建造合约。

In January 1979, cgn1 was canceled by the US government, and only ddg42 survived among all Aegis ships.

The U.S. Navy originally planned to order 16 DDG47s, but after the cancellation of CGN42, the number was increased to 18.

After Reagan came to power in the 80s, he proposed a policy for the U.S. Navy to maintain a size of 15 ships. The U.S. Navy planned to maintain aircraft carrier battle groups (CVBG), and each CVBG required three Ticonderoga-class ships to provide escort.

Therefore, the total demand for the Ticonderoga class increased to 26 ships, and by the mid-80s it increased to 27 ships.

The 1980s was a prosperous era for the expansion of U.S. military power and armaments. Orders like the Ticonderoga class continued to expand and were built in large numbers, which was unimaginable after the end of the Cold War.

Service history

On January 1980, 1, the United States announced that DDG1 would be reclassified as a guided missile cruiser CG to avoid the dilemma of having no cruisers in the fleet to support the situation after the previous generation of guided missile cruisers such as the Leahy class cruiser and the Becknap class were retired.

Since U.S. destroyers have lieutenant colonel vacancies for captains and cruisers have captain vacancies, if the number of cruisers is significantly reduced, it will seriously affect the personnel promotion of U.S. Navy academy-level officers.

In addition, the full load displacement of the DDG47 is already around 9000 tons, which is equivalent to the light cruiser during World War II, so qualification is not a problem.

The first four Ticonderoga-class ships have been assigned numbers 47 to 50 according to the guided missile destroyer numbering sequence, and will not be changed. Therefore, the guided missile cruiser has five empty numbers from 42 to 46, etc., generated from behind the Virginia-class nuclear-powered cruiser.

Therefore, the number of future Burke-class destroyers will skip the empty number caused by the Ticonderoga class and start from 51.

Technical characteristics of ship electrical system:

The Ticonderoga-class four-sided spy1a phased array antenna is divided into two groups. The antennas facing forward and right are installed on the forecastle structure, while the antennas facing directly aft and left are installed in the tail hangar. Above the structure, each of the two array antennas has a parallel radar transmitter to provide radio frequency energy.
