The Spruance-class destroyer was developed by the United States to replace the many World War II–built Allen M. Sumner- and Gearing-class destroyers, and was the primary destroyer built for the United States Navy during the 1970s and 1980s. It was named in honor of U.S. Navy Admiral Raymond A. Spruance, who successfully led major naval battles in the Asiatic-Pacific Theater during World War II such as the Battle of Midway and the Battle of the Philippine Sea.
A vertical launching system (VLS) is an advanced system for holding and firing missiles on mobile naval platforms, such as surface ships and submarines. Each vertical launch system consists of a number of cells, which can hold one or more missiles ready for firing. Typically, each cell can hold a number of different types of missiles, allowing the ship flexibility to load the best set for any given mission. Further, when new missiles are developed, they are typically fitted to the existing vertical launch systems of that nation, allowing existing ships to use new types of missiles without expensive rework. When the command is given, the missile flies straight up far enough to clear the cell and the ship, then turns onto the desired course.
The Delhi-class destroyers are guided-missile destroyers of the Indian Navy. Three ships of this class are in active service. The Delhi-class vessels were the largest vessels to be built in India at the time of their commissioning. The ships were built by Mazagon Dock Limited (MDL) at a cost of ₹750 crore each.
The Type 051 destroyer was a class of guided missile destroyers based on the hull of the Soviet Neustrashimy-class destroyer deployed by China. It was the first guided missile destroyer fielded by the People's Liberation Army Navy (PLAN), and the first designed and built in China. 17 were built from 1970 to 1990; it was not until the 21st century that China would again build a class in such large numbers.
The Type 052 (NATO/OSD Luhu-class destroyer is a class of destroyers developed in the People's Republic of China for the People's Liberation Army Navy. The Type 052 was an intermediate between the obsolescent Type 051 and the modern Type 052B destroyers. They were the first PLAN destroyers powered by gas turbines, and the first PLAN ships with modern combat direction systems. They were also part of the first generation of PLAN warships armed with surface-to-air missiles in the form of the short-range Crotale
The Type 052C destroyer is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy Surface Force (PLAN). The Type 052C introduced both fixed active electronically scanned array (AESA) radar and vertically launched surface-to-air missiles into PLAN service, making it the first Chinese warship with area air defence capability.
The Udaloy class, Soviet designation Project 1155 Fregat and Russian designation Project 11551 Fregat-M, are series of anti-submarine guided-missile destroyers built for the Soviet Navy, seven of which are currently in service with the Russian Navy. Twelve ships were built between 1980 and 1990, while the thirteenth ship built to a modified design, known as Udaloy II class, followed in 1999. They complement the Sovremenny-class destroyers in anti-aircraft and anti-surface warfare operations. The codename Udaloy comes from an archaic Russian adjective удалой, meaning daring or bold.
The Type 054 is a class of Chinese multi-role frigates that were commissioned in the People's Liberation Army Navy Surface Force in 2005. They superseded the Type 053H3 frigates. Only two ships, Ma'anshan (525), and Wenzhou (526), were completed before production switched to the VLS equipped improved Type 054A frigate.
The Sejong the Great-class destroyers, also known as KDX-III, are three guided-missile destroyers of the Republic of Korea Navy (ROKN).
The Type 730 is a Chinese seven-barrelled 30 mm Gatling gun/rotary cannon CIWS. It has a PLA Navy designation H/PJ12. It is mounted in an enclosed automatic turret and directed by radar, and electro-optical tracking systems. The maximum rate of fire is 5800 rd/m, and the effective range is up to 3 km.
The Type 345 (MR35) fire-control radar system is used to guide the HQ-7 short-range surface-to-air missile. The system is installed on many modern, and retrofitted Chinese navy ships.
The People's Liberation Army Navy Surface Force is the surface warfare branch of China's People's Liberation Army Navy (PLAN), consisting of all surface vessels in operational service with the PLAN. The PLAN Surface Force operates 661 ships organized into three fleets: the North Sea Fleet, the East Sea Fleet and the South Sea Fleet.
The People's Liberation Army Navy (PLAN) is the naval branch of the People's Liberation Army (PLA), the armed forces of the People's Republic of China. The PLAN force consists of approximately 250,000 men and over a hundred major combat vessels, organized into three fleets: the North Sea Fleet, the East Sea Fleet, and the South Sea Fleet.
The Type 051C destroyer is a long-range air-defence guided-missile destroyer built by China in its ongoing effort to create a true blue water navy. The ship uses the hull design of the older Type 051B, but is equipped with the advanced Russian S-300FM air defence missiles systems. Currently, two ships of this class have been launched and deployed by People's Liberation Army Navy North Sea Fleet.
The Sovremenny class, Soviet designation Project 956 Sarych (buzzard), is a class of anti-ship and anti-aircraft guided-missile destroyers of the Soviet and later Russian Navy. The ships are named after qualities, with "Sovremenny" translating as "modern" or "contemporary". Most of the ships have been retired from active service and one converted into a museum ship in 2018; as of 2021 three remain in commission with the Russian Navy with several in overhaul. Four modified ships were delivered to the People's Liberation Army Navy, and remain in service.
The Type 052D destroyer is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy. The Type 052D is a larger variant of the Type 052C; the Type 052D uses a canister-type, instead of revolver-type, vertical launching system (VLS) and has flat-paneled active electronically scanned array (AESA) radar. The new VLS is not limited to surface-to-air missiles, making the Type 052D China's first dedicated multi-role destroyer.
Shenzhen (167) is a Type 051B destroyer of the People's Liberation Army Navy. She was commissioned in February 1999.
The Type 055 destroyer is a class of stealth guided-missile destroyers constructed for the Chinese People's Liberation Army Navy (PLAN).
