turkey is desprate to sell their tech to the world. the fd200 and the fd-100 are among the many naval products they have to offer.
i heard the saudis were interested in the type 45. they witnessed the launch of one of the ships. but by that time production stopped and they went to france.
Sejong the Great Class / KDX-III Class Destroyer, South Korea
The Sejong the Great Class (Sejongdaewang Class) guided missile destroyers are being developed under the Korean Destroyer eXperimental (KDX) programme of the Republic of Korea Navy (ROKN).
"Sejong the Great Class destroyers are equipped with a combined gas turbine (COGAG) propulsion system."
Three units are being built by Hyundai Heavy Industries and Daewoo Shipbuilding & Marine Engineering. The destroyer class is also referred to as KDX-III
The lead ship in its class, Sejong the Great (DDG 991), was launched in May 2007. The destroyer was commissioned in December 2008. The second destroyer, Yulgok Yi I (DDG 992), was launched in November 2008 and delivered in September 2010.
The vessel entered service with the ROKN in June 2011. The third destroyer, Seoae Ryu Seong-ryong (DDG 993), was launched in March 2011. It is scheduled for commission in 2012.
KDX-III destroyer design
Apart from the longer hull, the overall design of KDX-III is identical to that of the Arleigh Burke Class destroyer. The KDX-III destroyers are the largest surface warships to carry the Aegis weapon system.
The destroyer has an overall length of 165m, beam of 21m and draft of 6m. The standard displacement of the ship is 7,700t and full load displacement is 10,000t.
The vessel can accommodate more than 300 crew members.
Sejong the Great destroyer missions
Sejong the Great Class destroyers are deployed in conventional naval warfare, anti-submarine warfare and anti-air warfare operations.
The destroyer conducts accurate strikes on the main enemy targets, and can protect mobile and convoy fleets from enemy aircraft and guided missiles.
It also supports the MASOC (Maritime Air Support Operation Centre) which controls all tactical aircraft operating on the sea.
The KDX-III destroyers allow the ROKN to protect Korean waters from air, surface, and subsurface threats.
Command and control
KDX-III destroyers are equipped with the Aegis combat system developed by Lockheed Martin. The Aegis system consists of SPY-1 radar and other components including SPY-1D (V) transmitter and MK 99 fire control system.
The radar acquires and tracks multiple targets such as aircraft and missiles.
This system, integrated with the MK 41 vertical launching system, delivers missiles against multiple threats in different attack scenarios. It can be used as an integrated single ship system and in a ship-to-ship network.
In July 2010, the Sejong the Great (DDG 991) successfully completed the combat system ship qualification trials (CSSQT) at the Pacific Missile Range Facility, off the Hawaiian island of Kauai.
Sejong the Great weapons
The Sejong the Great Class is armed with 16 SSM-700K Hae Sung long-range anti-ship missiles and 32 Hyunmoo III land attack missiles.
Two MK 41 vertical launch systems (VLS), one with 48 cells and another with 32 cells, are fitted forward and aft of the vessel for SM-2 Block IIIB missiles.
The ship point-defence is provided by a single 30mm Goalkeeper close-in weapon system (CIWS) and a RIM-116 rolling airframe missile (RAM) block 1 21-round launcher.
The main gun fitted forward is a 127mm L62 Mk-45 Mod 4 naval gun. The gun can fire at a rate of 16 to 20 rounds a minute for a range of 24km.
The anti-submarine weaponry includes K-ASROC Hong Sahng-uh (Red Shark) anti-submarine rockets (ASROC) and K745 LW Cheong Sahng-uh (Blue Shark) torpedoes.
A total of 16 rockets are fired from the launcher fitted on the aft.
The ASW control software is supplied by Kongsberg Maritime.
Sensors / radars
The AN/SPY-1D multifunction radar and four antenna arrays are housed in a single deck house. The ship is also equipped with AN/SPG-62 I/J band fire control radar, Atlas Elektronik bow-mounted DSQS-21 BZ-M sonar and MTeQ towed array sonar system.
Helicopter system
The KDX-III destroyers have a stern helicopter deck to support the operations of two Westland Lynx Mk 99 ASW helicopters. Hangar facilities are provided for the helicopters.
Propulsion
Sejong the Great Class destroyers are equipped with a combined gas turbine (COGAG) propulsion system.
"The lead ship in its class, Sejong the Great (DDG 991), was launched in May 2007."
Four General Electric LM2500 gas turbines driving the two shafts provide a total power output of 75MW.
The ship systems are powered by three Rolls-Royce AG9140RF gas turbine generator sets. The propulsion system provides a top speed of 30kt and a maximum range of 5,500nm at 20kt.

The missile battery of the Sejong the Great class is exceptional. Not even including the 21-cell RAM launcher, or even the 16 Hyunmoo III anti-ship missiles, they carry an incredible 128 missiles in three different VLC launch cell pads (one forward with 48 cells, one aft with 32 cells, and another 48-cell pad aft). This is a much larger stock of missiles than the 96 cells found on the
Arleigh Burke class, though it is still second-place to the
Kirov class battlecruisers (which have the world's largest missile battery, at 352 missiles).
The variety of missiles carried by the Sejong the Great class is staggering as well. These include the RIM-66M-5/SM-2ER Block IV Standard SSM-700K Haeseong with a range of 240 km, the Hyunmoo IIIB land attack cruise missile with a range of 1 000 km, the SSM-700K Haeseong anti-ship missile with a range of 150 km, the Red Shark (also called the K-ASROC) anti-submarine missile with a 18.5 km range, and the RIM-116B RAM surface to air missile with a range of 7.4 km. The K745 Blue Shark torpedo has an effective range of 18.5 km.
Though only two gun systems are carried, these are also quite formidable. The Mk-45 Mod 4 127-mm/62 dual-purpose gun fires 30.7 kg projectiles at a rate of fire of 20 rounds/minute, with a maximum range of 38.4 km, and is capable of engaging land targets, ships, aircraft, and even missiles. The Goalkeeper 30 mm CIWS fires 0.4 kg projectiles at up to 4 200 rounds/minute, with an effective range of 3 km, and can be used against watercraft as well as aircraft and missiles.
The complete ammunition loadout for the Sejong the Great class includes (but is likely not limited to) 680 127 mm shells, 1 190 30 mm shells, 21 RAM missiles, 6 Blue Shark torpedoes, and 16x SSM-700K Hae Sung missiles. The VLS load-out is variable, but the standard configuration consists of 80 SM-2 Standard missiles, 32 Hyunmoo IIIB missiles, and 16 Red Shark missiles. The loadout for the additional munitions carried by the helicopters is unknown.
In 2012, the ROKN formally made a request to the government for three additional Aegis warships, with an eye toward having them in commission by 2027. If these vessels are authorized, it is likely that they will be additional Sejong the Great class Destroyers, or possibly an evolved version of the design.
The manufacturers retain the ability to construct additional Sejong the Great class, but it is unknown as of late 2015 if any other will be ordered by the ROKN, and very unlikely that KDX-III type vessels would be offered for export, as many of its key technologies are classified and/or barred from further proliferation by the US government.
Barring unforeseen developments, the Sejong the Great class destroyers will remain in service until at least the mid-2030s.
