The People's Liberation Army Navy recently introduced two domestically designed and built guided missile destroyers that include Aegis-type radars and related technologies. Known as Project 052C guided missile destroyers (DDGs), the ships feature Aegis-type phased array panels, vertical launch systems, long-range missiles and considerable command and control. These capabilities were not found on any previous Chinese-built DDGs. The design of a lead ship with prototype Aegis radar, combat direction links and a vertical launch system (VLS) into a small 6,600-ton hull is an ambitious development. The smallest U.S. Navy Aegis ship with VLS is the 8,400-ton Arleigh Burke-class DDG 51. Russia had its Aegis-equivalent Sky Watch system only on 30,000-ton aircraft carriers. The nine years of sea test development prior to the U.S. Navy's first installing Aegis on the warship USS Ticonderoga CG 47 indicates the complexity and the engineering effort necessary to build a successful Aegis system. The fact that the Soviet Union gave up on an Aegis system after years of frustrating problems on two warships also shows the extreme difficulties. China is building only two 052C ships, and the next ship under construction will have a different Aegis and VLS suite. Even so, the mere existence of People's Liberation Army Navy (PLAN) warships with long-range phased array radar, communications to other naval assets and over-the-horizon ship-to-ship missiles (SSMs) complicates planning by other naval powers for the TaiwanStraits or other disputed Pacific Ocean waters. The first sea platform for the U.S. Navy Aegis was the trial ship USS Norton Sound AVM-1 in 1974. The first warship full-up four-panel Aegis system was on the Ticonderoga in 1983, which had 50 meters between the fore and aft deckhouse arrays. The first Aegis destroyer with the single deckhouse array SPY-1D was the 8,400-ton Arleigh Burke lead ship in 1989. More than 50 DDG 51-class ships have been built in this highly successful and constantly upgraded class of warships. All cruiser and destroyer SPY-1 variant antennas are 3.7 meters in diameter and measure 13.5 meters vertically, and they have an F-band frequency of from 3100 to 3500 megahertz. In 1988, the Soviet Union installed its first Aegis-type Sky Watch on two full-deck aircraft carriers. Each of the four square-plate phased array antennas measured about 5 meters in diameter, and their frequency was estimated to be F-band at about 850 megahertz. This is similar to the Top Plate radar that was mounted on previous Soviet carriers for long-range detection. The port array was 60 meters forward from the starboard array. The Soviets seem to have had considerable trouble in exercises with their Gorshkov phased array radar, as mechanical scanning Top Sail/Top Pair radars replaced it on the next Soviet carrier, the Tblisi. Sea operations attempting to successfully target incoming threats using external ship or aircraft platforms also seem to have failed. China's first 6,600-ton missile destroyer with an Aegis-type four-plate phased array antenna is the Lanzhou DDG 170 launched in Jiangnan Shipyard in April 2003. The DDG 171 followed six months later. Their undesignated Chinese radar is different from the Aegis or Sky Watch phased array radars. This radar is C-band instead of L- or F-band, and it has convex curved arrays instead of flat panels. The four arrays are 4.6 meters high x 3.9 meters wide, and they face out from the forward deckhouse as on the U.S. DDG 51. China reportedly has purchased two advanced Russian phased array radars for a follow-on larger air defense DDG 103 ship that is under construction at the Dalien shipyard. The short one- or two-ship production runs are a trademark of post-Luda DDG designs. When the U.S. Navy installed its first MK 41 VLS on the Ticonderoga-class Aegis cruiser CG-52 in 1989, it featured 64 missile cells forward and 32 cells aft. The MK 41 VLS cells launch multiwarfare missiles. The first Russian VLS trials were with SAN-6 missiles on the fourth Kara cruiser in 1977, and the 8,000-ton Udaloy DDG had eight SAN-9 VLS hatches. Both SAN-6 and SAN-9 VLS systems featured round modules with eight cells each and had a large unique Top Dome or Cross Sword acquisition and guidance fire control director and radar/datalink.
