Code for Unplanned Encounters at Sea

Given the fact that both sides are tracking movements of every ship in that area,  it is hard to believe this is an unplanned encounter by either side. "Funny how I keep bumping into you"

While operating in international waters and airspace near the Spratley’s, Fort Worth conducted flight operations with its MQ-8B Fire Scout unmanned aircraft system and MH-60R Seahawk helicopter. Fort Worth encountered multiple People’s Liberation Army–Navy [PLA(N)] warships, each time taking the opportunity to use the Code for Unplanned Encounters at Sea (CUES).

“Just like our first meeting in February with a PLA(N) warship, guided-missile frigate Hengshui (FFG 572), our interactions with Chinese ships continue to be professional and CUES helps clarify intentions and prevent miscommunication,” said Cmdr. Matt Kawas, Fort Worth Crew 103 commanding officer.

This PLAN Mediterranean naval drill has nothing to do with anything, I swear


China, Russia launch joint naval drills

(Source: Xinhua)   2015-05-11

   MOSCOW, May 11 (Xinhua) -- Chinese and Russian naval forces on Monday launched joint military exercises in the southern Russian port city of Novorossiysk.

  Military officials from both sides attended a ceremony to mark the beginning of the "Joint Sea-2015" drills, the fourth since joint China-Russia sea drills began in 2012.

  The drills, slated for May 11-21 in the Mediterranean and involving nine surface ships from both navies, are to be staged in four phases, focusing on maritime defense, replenishment and escorting.

  The two sides will prepare detailed arrangements for the drills later in the day, and the ships are expected to leave Novorossiysk for waters in the Mediterranean on Tuesday.

  "The joint drills are not aimed at any third party and have nothing to do with the political situation in that region," a Russian Defense Ministry spokesman said.

  Geng Yansheng, a spokesman for the Chinese Defense Ministry, said earlier in the day that the drills will deepen friendly and pragmatic cooperation between China and Russia, and boost response operation capabilities in the event of security threats at sea.

  Prior to the drills, Fan Changlong, vice chairman of China's Central Military Commission, said when holding talks with Russian Defense Minister Sergei Shoigu in Moscow that China will work with Russia to deepen their pragmatic military cooperation.

Since there is no RPG protection net spotted,  those guns must be deployed in a long rang fire support role instead of direct assault.

How the QBZ-95 bullpup’s action works




by Timothy Yan, Original article on The Firearms Blog

qbz_2
















The Chinese QBZ-95 bullpup has been in service for two decades and due to its sheer production, over 1.65 million so far, it will be the most prolific bullpup ever built. I did a detailed write-up on the QBZ-95 for Guns & Ammo SIP in 2006. Since then, that article has been used by many writers and researchers as reference. However, there’s still some confusion and misunderstanding on the QBZ-95’s inner workings. I hope this will help clarify the matter.


qbz_1
The QBZ-95 is one of the four post-World War II military rifle designs that use a striker-firing mechanism. The other 3 in chronologic order are: the Czech Vz 58, the Japanese Type 64, the Russian AS and VSS twins. Unlike the rotating hammer firing mechanism found on the majority of the modern rifles, a striker-fired rifle uses either a spring-loaded firing pin or a linear hammer to fire the chambered cartridge.
The spring-loaded firing pin type is common in the majority of bolt-action rifles and modern striker-fire pistols such as the Glock. The linear hammer type is used by most striker-firing selective fire rifles. This particular type of striker-firing system has a spring-loaded hammer piece that reciprocates forward and backward in the receiver.

qbz_4
The Czech Vz 58 was based on an early post-WWII indigenous select-fire full-caliber rifle design but it was redesigned to chamber the Russian M43 7.62x39mm cartridge. The Vz 58 was developed in 1958 and it is still in service with the Czech and Slovakian militaries. Its action uses a Walther style dropping block locking system with a short-stroke gas system. The Vz 58’s linear hammer type striker-firing system was the main inspiration for the trigger and striker design of the QBZ-95. Although, the QBZ-95’s striker design is conspicuously different than that of the Vz 58’s.
The Japanese Type 64 was developed in 1964 and chambers the 7.62x51mm full power round, while it normally uses a reduced power version of the 7.62x51mm. The Type 64 is still in limited service with the JSDF. Design wise, the Type 64 uses a short-stroke gas system with a tilting bolt lock action.
The Russian AS special purpose rifle was developed in the late 1980s. Its suppressed VSS twin went into service about the same time as the QBZ-95. Both the AS and VSS are chambered in the Russian 9x39mm special purpose cartridge. The striker and trigger part of both Russian weapons are very similar to that of the Czech Vz 58, just smaller in size. The Russian weapons use long-stroke gas system and an AR-15 style multi-lug rotating bolt.

The following animation from CCTV shows how the QBZ-95’s action works:
qbz95_action
1) – After the 5.8x42mm cartridge is fired, the propellant gas passes through the gas port at front of the barrel (in light blue) and drives back the short-stroke gas piston system (in dark green).
2) – The long extension of the bolt carrier (in brown) receives a tap from the short-stroke gas piston while the whole unit starts traveling back. The gas piston spring (in green & white) returns the short-stroke gas piston.
3) – After a short travel, the cam track in the bolt carrier turns and unlocks the 3-lug bolt (in red). The empty cartridge case (in green) is extracted then ejected out of the weapon by a receiver mounted solid ejector.
4) – While the bolt carrier group (in brown and red) is moving back, it also pushes back the striker (in dark blue) along and compresses the striker spring. The reciprocating components come to a soft stop without hitting a solid surface with the help of a recoil buffer (in purple).
5) – The bolt carrier group (in brown and red) starts to travel forward again from spring pressure of the main spring. The striker (in blue) and striker spring is being held back by the sear in the trigger mechanism.
6) – The bolt (in red) strips a new 5.8x42mm round from the magazine and chambers it. The forward moving bolt carrier (in brown) turns the bolt (in red) to engage its 3 locking lugs into the locking slots on the trunnion. The weapon is read to fire.
7) – By pressing on the trigger (in yellow), the connected linkage (in white) pulls down the sear in the trigger mechanism and releases the striker (in dark blue). The striker impacts on the firing pin and fires the chambered 5.8x42mm cartridge. The action cycle repeats again.
The only changes in the latest QBZ 95-1 variant is the redesign of the recoil buffer (in purple) to use a coil spring with a rotating movement, and a new trigger mechanism that moves the selector forward and above the pistol grip. The fixed forward grip that makes up the trigger guard on the original is also replaced by a simple round trigger guard on the later models. Plus, the QBZ 95-1 barrel has a faster twist rate.
Unlike the relatively simple looking linear hammers on the Vz 58 and AS/VSS, the QBZ-95’s striker piece has a very complex shape. The striker spring arrangement is also very different. Instead of having two parallel springs, on the QBZ-95, the main spring and the striker spring are in-line and uses the same spring guide rod.

qbz_3
Since the end of the Cold War, modern combat rifles are being produced in much smaller numbers. I estimate that the Arsenal 276 and Arsenal 256 will still need to make at least 5 million copies of the updated QBZ-95 variants just for replacing all the old Type 81, QBZ-56C and the worn out initial QBZ-95 model in the Chinese service. The Israeli Tavor family (includes the newer X95) of bullpups will get adapted by more countries around the world, but just in the total production numbers alone, the Chinese QBZ-95 will outnumber all other bullpup military rifles combined.

(Reuters) - China will hold joint naval drills with Russia in mid-May in the Mediterranean Sea, the first time the two countries will hold military exercises together in that part of the world, the Chinese Defence Ministry said on Thursday.

China and Russia have held naval drills in Pacific waters since 2012. The May maneuvers come as the United States ramps up military cooperation with its allies in Asia in response to China's increasingly assertive pursuit of maritime territorial claims.

A total of nine ships from the two countries will participate, including vessels China now has on anti-piracy patrols in waters off Somalia, Chinese Defence Ministry spokesman Geng Yansheng told a monthly news briefing.

"The aim is to deepen both countries' friendly and practical cooperation, and increase our navies' ability to jointly deal with maritime security threats," Geng said.

"What needs saying is that these exercises are not aimed at any third party and have nothing to do with the regional situation."

Geng gave no specific date for the drills, which will be focused on navigation safety, at-sea replenishment, escort missions and live fire exercises.

China and Russia are both permanent members of the U.N. Security Council and have close diplomatic, economic and military ties, with China traditionally relying on Russia for its most advanced equipment.

President Xi Jinping is expected to visit Moscow next month to attend a parade celebrating the end of World War Two.

China has been increasingly flexing its military muscles since Xi assumed the presidency in 2013, jangling nerves around the region and globally, though Beijing insists it is a force for peace and threatens nobody.

China's navy has become a focus of Xi's efforts to better project the country's power, especially in the disputed South China Sea.

U.S. President Barack Obama accused China on Tuesday of "flexing its muscles" to advance its territorial claims at sea.[ID:nL1N0XP111]

China says about 90 percent of the 3.5 million sq km (1.35 million sq mile) South China Sea is its sovereign territory. The Philippines, Taiwan, Malaysia, Brunei and Vietnam also claim large parts.
