Chinese Frigate Handan (579)
''Handan'' (579) is a Type 054A frigate of the People's Liberation Army Navy. She was commissioned on 16 August 2018. Development and design The Type 054A carries HQ-16 medium-range air defence missiles and anti-submarine missiles in a vertical launching system (VLS) system. The HQ-16 has a range of up to 50 km, with superior range and engagement angles to the Type 054's HQ-7. The Type 054A's VLS uses a hot launch method; a shared common exhaust system is sited between the two rows of rectangular launching tubes. The four AK-630 close-in weapon systems (CIWS) of the Type 054 were replaced with two Type 730 CIWS on the Type 054A. The autonomous Type 730 provides improved reaction time against close-in threats.

E-3 Sentry
The Boeing E-3 Sentry is an American airborne early warning and control (AEW&C) aircraft developed by Boeing. E-3s are commonly known as AWACS (Airborne Warning and Control System). Derived from the Boeing 707 airliner, it provides all-weather surveillance, command, control, and communications, and is used by the United States Air Force, NATO, French Air and Space Force, Royal Saudi Air Force and Chilean Air Force. The E-3 is distinguished by the distinctive rotating radar dome (rotodome) above the fuselage. Production ended in 1992 after 68 aircraft had been built. In the mid-1960s, the U.S. Air Force (USAF) was seeking an aircraft to replace its piston-engined Lockheed EC-121 Warning Star, which had been in service for over a decade. After issuing preliminary development contracts to three companies, the USAF picked Boeing to construct two airframes to test Westinghouse Electric and Hughes's competing radars. Both radars used pulse-Doppler technology, with Westinghouse's d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 054A Frigate
The Type 054A (NATO/ OSD Jiangkai II) is a class of guided-missile frigate from the People's Republic of China. It is a development of the Type 054 frigate; compared to its predecessor, the Type 054A has medium-range air defense capability in the form of Type 382 radar and vertically launched (VLS) HHQ-16 surface-to-air missiles.Schwartz (2015): page 28 The Type 054A entered service with the People's Liberation Army Navy (PLAN) in January 2008,''Jane's Fighting Ships'' (2015): page 144 and was a key component of the PLAN's surface fleet by the late 2010s.Willett (2019): page 24Willett (2019): page 26 Production was ongoing in 2021. Design The Type 054 was heavily influenced by the from France, and so reflected the strategic and operational requirements of that country. The development of the Type 054A may have been driven by China's need to address high-intensity armed conflict.Collins et al. (2014): page 2 The Type 054A uses the same stealthy hull form as the Type 054. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
F-22P
The ''Zulfiquar''-class frigate ( ur, ذوالفقار, lit=''Sword''), also known as F-22P or in English: ''Sword'' class, is a class of multi-mission guided missile frigates, in service with the Pakistan Navy. The class is based on an updated model of the Chinese design, the Type 053H3. The frigates were designed and built jointly in Hudong–Zhonghua Shipbuilding in China and the KS&EW Ltd. in Pakistan. The frigates perform missions including air defense, enemy interdiction, extraction and patrolling the economic exclusive zone (EEZ). History Negotiation, procurement, and development After the return of the and s in 1994, Pakistan entered in negotiation with China to jointly built and design the class of four frigates in 1996–1999. Initial interests were directed towards procuring the Type 053 and Type 054 frigates in 2004, eventually signing a bilateral agreement with China to design the frigates influenced from both designs at the initial price of $600 million USD ...

Luzhou Class Destroyer
The Type 051C destroyer (NATO reporting name: Luzhou class) 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 (Luhai class), 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. Background The construction of the Luzhou-class destroyer at China's northern Dalian Shipyard was revealed in 2004 with the help of Internet photographs. A disadvantage of the Type 051C is that it lacks the stealthier radar cross-section found on the newer Chinese warships. The ship also possesses less advanced steam turbine propulsion compared to gas turbine propulsion present in all newer Chinese destroyers. The Type 051C is a stop gap measure to provide long range area air defense to the fleet by mating the mature hull design with ...

Type 052D Destroyer
The Type 052D destroyer (NATO/ OSD Luyang III-class 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)Li: page 44 and has flat-panelled active electronically scanned array (AESA) radar.McDevitt: page 62 The new VLS is not limited to surface-to-air missiles, making the Type 052D China's first dedicated multi-role destroyer. Etymology Chinese media informally calls the Type 052D the Chinese Aegis, portraying it as a peer of contemporary United States Navy ships equipped with the Aegis Combat System.Holmes: page 4 The appearance of the Type 052D, with flat-panelled radar and canister-based VLS, has encouraged this informal use. Design Sensors The Type 052D is equipped with Type 346A AESA and Type 518 L-band radar. The Type 052D is also equipped with both variable depth (VDS) and linear tow ...

Lanzhou Class Destroyer
The Type 052C destroyer (NATO/ OSD Luyang II-class 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,McDevitt: pages 59-60 making it the first Chinese warship with area air defence capability. , six of these destroyers had been built and were operational. Program The first two ships, and , were laid down at the Jiangnan Shipyard in Shanghai in 2002, and entered service in 2004 and 2005 respectively. No new ships were laid down until 2010;Li: page 44 the pause may have been due to the relocation of the shipyard.McDevitt: pages 59 Design The Type 052C appears to share the same basic hull design as the Type 052B destroyer, which in turn is based on the Type 051B destroyer. Stealth features are incorporated. The Type 052C uses predominantly Chinese systems deri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guangzhou Class Destroyer
The Type 052B (NATO/ OSD Luyang I-class destroyer is a class of guided-missile destroyers in the Chinese People's Liberation Army Navy Surface Force (PLAN). The Type 052B was China's first modern destroyer designKirchberger (2015): page 195McDevitt (2017): page 57 and the first Chinese design to incorporate true medium-range air defence capability in the form of Russian Shtil-1 (improved navalized Buk, NATO designation SA-N-12) surface-to-air missiles (SAM).Schwartz (2015): page 26 Two ships - ''Guangzhou'' and ''Wuhan'' - were built and commissioned in July 2004. Programme In the early 2000's, China pursued multiple - and sometimes concurrent - programmes to acquire modern destroyers, purchasing s from Russia and constructing the Type 052B, Type 051C, and Type 052C.Kirchberger (2015): page 193 These ships also represented steps to develop adequate air defense capabilities by adopting Russian air defense technology.;Schwartz (2015): pages 25 the 25-km range Uragan (navalized ...

Type 052 Destroyer
The Type 052 (NATO/ OSD Luhu-class destroyer is a class of destroyers developed in the People's Republic of China (PRC) for the People's Liberation Army Navy (PLAN). The Type 052 was an intermediate between the obsolescent Type 051Kirchberger (2015): page 186 and the modern Type 052B destroyers.Kirchberger (2015): page 195McDevitt (2017): page 57 They were the first PLAN destroyers powered by gas turbines, and the first PLAN ships with modern combat direction systems (CDS). 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 (called HQ-7 in Chinese service.)Kirchberger (2015): page 231 The Type 052 used subsystems imported from the United States and the European Union. The embargo after the 1989 Tiananmen Square protests and massacre ended the supply of and support for those subsystems, limiting production to two ships and likely impacting their operating efficiency due to system integration iss ...

Gryazev-Shipunov GSh-6-30
The Gryazev-Shipunov GSh-6-30 (Russian: Грязев-Шипунов ГШ-6-30) is a Russian 30 mm rotary cannon aircraft-mounted and naval autocannon used by Soviet and later CIS military aircraft. The GSh-6-30 fires a 30×165mm, projectile. Description The GSh-6-30, designed in the early 1970s and entering service in 1975, has a six barrel design that is similar to the Gryazev-Shipunov GSh-6-23. It was based on the naval AO-18 used in the AK-630 system. Unlike most modern rotary cannons, it is gas-operated rather than hydraulically driven, allowing it to "spin up" to maximum rate of fire more quickly, allowing more rounds to be placed on target in a short-duration burst. This makes the weapon advantageous in dogfights, where pilots often have a very small window for engaging the enemy. Ignition is electrical, as with the smaller GSh-6-23. On the MiG-27 "Flogger" the GSh-6-30 had to be mounted obliquely to absorb recoil. The gun was noted for its high (often uncomfortable ...

GAU-8/A Avenger
The General Electric GAU-8/A Avenger is a 30 mm hydraulically driven seven-barrel Gatling-style autocannon that is primarily mounted in the United States Air Force's Fairchild Republic A-10 Thunderbolt II. Designed to destroy a wide variety of ground targets, the Avenger delivers very powerful rounds at a high rate of fire. The GAU-8/A is also used in the Goalkeeper CIWS ship weapon system, which provides defense against short-range threats such as highly maneuverable missiles, aircraft, and fast maneuvering surface vessels. The GAU-8/A is currently produced by General Dynamics. History The GAU-8 was created as a parallel program with the ''A-X'' (or Attack Experimental) competition that produced the A-10. The specification for the cannon was laid out in 1970, with General Electric and Philco-Ford offering competing designs. Both of the A-X prototypes, the YA-10 and the Northrop YA-9, were designed to incorporate the weapon, although it was not available during the initial compe ...
