Kolkata handed over to Navy*
The INS Kolkata, lead ship in the Kolkata-class stealth destroyers, was handed over to the Indian Navy on Thursday after extensive sea trials and tests, 11 years after the construction began in 2003 at the Mazgaon Docks Limited (MDL). The ships are the second group of three indigenously built stealth warships after the Shivalik-class boats, while the official commissioning ceremony is expected to take place in a month’s time.
The same ship had seen naval engineer Commander Kuntal Wadhwa lose his life after a prolonged exposure to CO2 gas on March 6, suspected to be caused by a malfunctioning fire fighting system. “The ship has finished construction with all user acceptance trials, sea trials and testing of the weapons systems completed. The ship will still be called Yard 701 but designated the INS Kolkata after the commissioning ceremony,” said Rear Admiral (retired) R.K. Shrawat, MDL’s chief managing director.
Most importantly, the naval version of the Brahmos cruise missile was also fired from the ship off the coast of Karwar about a month ago, to prove the boat’s and weapon handling system. “The purpose was to test the ship’s capability to withstand the missile, but not the missile itself,” said an MDL source. The main feature of the ship, however, according to naval officers, is the ‘multi-function radar’, the first of its kind in the country. “It is more in tune with modern naval warfare technologies than the stealth feature,” said an officer.
The Indian Navy can come back with technical complaints or suggesting modifications by availing the one-year guarantee period in the next 12 months, in the event of which Form D448 would be invoked. Sources, however, said that all technical issues were raised by the IN team, liaisoning with the MDL, during the construction phase itself.
Meanwhile, two other sister ships of the class, INS Kochi and INS Chennai are undergoing construction with the handing over to the IN slated to be in late 2014 and mid-2015 respectively.

PLA Navy group begins long-distance exercise*
A group of warships from the People's Liberation Army Navy set sail from a port in Hainan province on Monday and started a long-distance patrol training mission.
The group is composed of several surface warships from the South Sea Fleet: the amphibian landing craft Changbaishan and the missile destroyers Haikou and Wuhan, the PLA Navy said in a statement on Monday.
The training operation will involve a range of tasks, including supportive engagement — assisting other ships that are exchanging fire with hostile forces, said the statement.
They will also practice tactical maneuvers in the South China Sea, the Western Pacific Ocean and the Eastern Indian Ocean.
The group carries three helicopters, a hovercraft and a company of marines. The flagship, the Changbaishan, is the most advanced amphibian landing craft in the Chinese navy, boasting a heavy tonnage and cutting-edge weapons.
The Haikou and Wuhan missile destroyers are capable of defending against enemy aircraft and submarines as well as incoming missiles. They have previously taken part in escort missions in the pirate-plagued Gulf of Aden, as well as a joint drill with the Russian military, according to the PLA Navy statement.
Soon after leaving port, the two destroyers set off to join submarines on an exercise simulating the breaking of a hostile blockade.
"The patrol training mission aims to test the combat capabilities of the navy's ships, submarines and aircraft," said Lieutenant Admiral Jiang Weilie, commander of the South Sea Fleet.
"It is also intended to explore effective methods for long-distance training operations, which have become a regular thing for our navy," he said, adding that the mission is the navy's first long-distance voyage of 2014.

The Z-boat floats! Zumwalt launched into the night*

Zumwalt afloat on the evening of Oct. 28.

With little ceremony, Bath Iron Works launched the ZUMWALT (DDG 1000) into Maine’s Kennebec River on Monday afternoon, Oct. 28.
The 600-foot-long ship — the largest destroyer ever built — was floated off from a floating drydock that had been moved into the middle of the river. The operation to move the drydock out into the river, flood the dock, float off the Zumwalt and move her to a pier took about eight hours, according to Matt Wickenheiser, a spokesman for the shipyard.
The ship began its translation — an engineering term for transferring the ship from land to water — from the shipyard’s land-level construction facility to a floating dry dock Friday, Oct. 25.
“This is the largest ship Bath Iron Works has ever constructed and the Navy’s largest destroyer,” said Capt. Jim Downey, the Zumwalt-class program manager for the Navy’s Program Executive Office, Ships. ”The launch was unprecedented in both its size and complexity.”
The ship’s christening, planned for Oct. 19 but put off because of the government shutdown, won’t take place until sometime in the spring, the Navy said. Zumwalt is about 87 percent complete, but more than a year of work is needed before the ship is delivered in late 2014. Even then, further development, tests and trials of the ship’s combat systems will continue well into 2016.
Zumwalt is the first of three ships in the DDG 1000 class. Major portions of the Michael Monsoor (DDG 1001) already have been assembled, and with Zumwalt launched, more sections will be joined together.
Construction also is proceeding on the Lyndon B. Johnson (DDG 1002).

US Navy demonstrates long-range land attack projectile capability*
During the tests, conducted as part of land-based flight qualification during the engineering and manufacturing development (EMD) phase, the guided projectile has undergone nine launches and successfully hit targets, placed approximately 45nm from the launch site.
The demonstration validated the projectile's gun launch, rocket motor ignition, guidance acquisition, navigation to target and warhead detonation.
PEO IWS Navy Surface Ship Weapons major programme manager captain Mike Ladner said that the team has completed live fire test and evaluation (LFTE) data collection, marking a step ahead in completing the development programme.
"Additionally, flying the tactical software was a major step in reducing the remaining technical risk in the programme," Ladner added.
Additionally, the projectile demonstrated its tactical software including multiple round simultaneous impact (MRSI) capability, which enables the ship to fire several rounds and adjusts the projectile trajectory to synchronise time of arrival at the targets.
The testing also assessed the potency of the round to lifecycle stresses and stimuli such as temperature, vibration and humidity.
The LRLAP rocket-assisted guided projectile will support land-attack operations onboard the US Navy's DDG 1000 Zumwalt-class guided missile destroyers.

La Escuadra de Instrucción japonesa en Barcelona
La flotilla de instrucción de la Fuerza Marítima de Autodefensa de Japón recaló en la ciudad condal durante su viaje de circunnavegación
28/08/2013.- Entre los días 26 y 29 de agosto permanece atracada en el puerto de Barcelona la Escuadra de Instrucción de la Fuerza Marítima de Autodefensa de Japón (Japan Maritime Self-Defense Force o JMSDF). La flotilla está al mando del contralmirante Fumiyuki Kitagawa, y se compone del buque escuela «Kashima» y los destructores «Isoyuki» y «Shirayuki», ambos de la clase «Hatsuyuki», éste último fue convertido en buque escuela en 2011.
El Japan Training Squadron zarpó de Tokio el 22 de mayo y tiene prevista la arribada al mismo puerto el 30 de octubre, dando la vuelta al mundo y recorriendo alrededor de 30.000 millas. Visitarán 18 paises atracando en los puertos de Pearl Harbor (EEUU); Manzanillo (México); Panamá (Panamá); Halifax (Canadá); Portsmouth (Gran Bretaña); Helsinki (Finlandia); San Peterburgo (Rusia); Gdynia (Polonia); Kiel (Alemania); Brest (Francia); Barcelona (España); Tarento (Italia); Split (Croacia); Yibuti; Colombo (Sri Lanka); Yangon (Myanmar); Sihanoukville (Camboya) y Da Nang (Vietnam), desde la cual regresarán a Tokio finalizando su viaje de instrucción.
Como dato anecdótico, durante la jornada del lunes 26 la flotilla de la JMSDF compartió muelles en la dársena barcelonesa con otra iniciativa de origen japonés, el denominado Peace Boat o Buque de la Paz, se trata de un buque de crucero auspiciado por una ONG nipona que también se encuentra realizando su vuelta al mundo.
El buque escuela 3508 «Kashima», es una nave especialmente diseñada para su empleo como unidad docente en la flota de la JMSDF. Su construcción fue autorizada en 1991, aunque la situación bélica vivida en aquellas fechas (Guerra del Golfo), retrasó en dos años el inicio de su construcción. Se trata de un buque de 4.050 toneladas de desplazamiento a plena carga; con eslora total de 143 metros, manga de 18 metros y calado de 4,6 metros. La propulsión es CODOG, es decir combinada diesel o turbinas de gas, compuesta por 2 motores diesel Mitsubishi S16U-MTK de 8.000 hp y 2 turbinas de gas Rolls-Royce Spey tipo SM1C de 26.150 shp cada una. Alcanza una velocidad máxima de 25 nudos y cuenta con una autonomía de 7.000 millas náuticas navegando a una velocidad de crucero de 18 nudos.
Tiene una dotación de 220 personas y puede transportar 140 alumnos en camarotes dobles, incluyendo personal femenido. A pesar de su condición de buque docente, dispone de un sistema defensivo compuesto por un cañón bivalente OTO-Melara de 76/62 mm, 2 ametralladoras de 12,7mm y 2 montajes triples de tubos lanzatorpedos antisubmarinos Mk-68 de 324 mm.
En popa cuenta con una amplia cubierta de vuelo para helicópteros aunque en su diseño se pensó también como plataforma multifunción para la realización de instrucción, ejercicio físico, uso ceremonial y actividades similares.
A pesar de su conversión a buque escuela el destructor 3517 «Shirayuki» mantiene el mismo equipamiento que su hermano gemelo 127 «Isoyuki» (Foto: Javier Sánchez García / Revista Naval)
La clase completa se compuso de 12 destructores, una de las numerosas y homogéneas series de la actual flota de autodefensa japonesa, construidos a lo largo de la década de 1980. En la actualidad sólo persisten siete unidades en su función original, habiendo sido convertidos en buques escuela los destructores «Shimayuki» 3513 (ex 133), desde el 18/03/1999; «Shirayuki» 3517 (ex 123), desde el 15/03/2011; y «Setoyuki» 3518 (ex 131), desde el 14/03/2012. Causando baja los «Hatsuyuki» 122 (25/06/2010) y «Hamayuki» 126 (14/03/2012).
Estos buques fueron diseñados originalmente con la superestructura de aluminio, siguiendo los pasos de otras unidades construidas en aquellas fechas, pero al comprobarse los daños sufridos por buques de la Royal Navy durante la guerra de las Malvinas (1982) por el uso de este metal y sus graves consecuencias al inflamarse, se tomó la decisión de sustituirlo en la construcción por el acero clásico, con lo que partir del «Yamayuki» 129 los buques desplazan 100 toneladas más.
Por lo demás, estos buques tienen un desplazamiento a plena carga de 4.000 toneladas, siendo sus dimensiones de: 130 metros de eslora, 13,60 metros de manga y 4,10 metros de calado. Tienen un grupo propulsor del tipo COGOG (combinación Gas/Gas) compuesto por dos turbinas de gas Kawasaki-Rolls Royce Olympus TM3B y otras dos RR-Kawasaki RM-1C que desarrollan una potencia total de 45.000 hp (TM3B) y 9.900 hp (RM1C), siendo utilizadas para alcanzar una velocidad máxima de 30 nudos o de crucero 16 nudos, respectivamente.
Estos destructores pueden enfrentarse a cualquier tipo de amenaza, para ello cuentan con un sistema defensivo artillero compuesto por un cañón OTO-Melara 76/62 mm y dos cañones de defensa de punto CIWS Phalanx de 20 mm. Un componente misilístico formado por dos lanzadores cuádruples de misiles antibuque Harpoon, un lanzador RIM-7 Mk 29 Sea Sparrow y un lanzador óctuple para cohetes antisubmarinos ASROC. Además cuentan con dos montajes triples HOS-301 de 324 mm ASW y las instalaciones necesarias para operar con un helicóptero ASW SH-60J.
Disponen de un sofisticado equipamiento electrónico dotado con radares de fabricación japonesa OPS-14 exploración/búsqueda aérea y OPS-18 exploración/búsqueda superficie, entre otros. Un sónar antisubmarino OQS-4 (de casco) un sistema OQR-1 TACTASS y los equipos de guerra electrónica NOLR-6C ESM y OLT-3 ECM. También cuentan con un sistema lanzaseñuelos de origen estadounidense SRBOC Mk 36. El sistema de combate OYQ-5 TDPS (LINK-14) es una versión japonesa del estadounidense NTDS utilizado por los buques de la US Navy. La dotación de estos buques de 200 personas.

Royal Navy decomissions final Type 42 vessel*
The British Royal Navy's last Type 42 destroyer (Batch 3), HMS Edinburgh (D97) has been officially decommissioned at Portsmouth Naval Base, marking the end of its 30-year operational life.
Cammell Laird-built HMS Edinburgh will be replaced by a new-generation 152.4m-long 7,350tType 45 Daring-class
vessels.
HMS Edinburgh commanding officer commander Nick Borbone said: "These are the final moments of HMS Edinburgh and the final moments of the Type 42, a class which has served the navy and the nation with distinction."
Prior to its decommissioning, the 141m-long, 5,200t HMS Edinburgh has completed its final deployment conducting routine operations across the South Atlantic, including supporting counter-narcotics efforts in the West African region and providing support and reassurance to UK overseas territories.
Initially deployed to escort numerous merchant ships safely through the region off the Gulf in 1987, the ship was also deployed to escort the helicopter carrier HMS Ocean while supporting Royal Marines ashore in the second Gulf War in 2003.
Armed with a twin Sea Dart missile launcher, 4.5in Mk8 gun and a Phalanx close-in weapon system (CIWS), the ships can operate independently and conduct patrol and boarding operations, anti-narcotics and anti-piracy patrols, as well as provide humanitarian assistance.
Capable of carrying a crew of 287, the Type 42 ship underwent a £17.5m refit by BAE systems in 2010, when its propulsion machinery, auxiliary and weapons systems, sensors and accommodation were upgraded.

Iran launches new destroyer in Caspian Sea*
TEHRAN – A new domestically manufactured destroyer, named the Jamaran 2, was launched in the Caspian Sea during a ceremony held in the port city of Bandar-e Anzali, in the northern Iranian province of Gilan. President Mahmoud Ahmadinejad, Defense Minister Brigadier General Ahmad Vahidi, Major General Hassan Firouzabadi, the chief of the general staff of Iran’s armed forces, and Rear Admiral Habibollah Sayyari, the commander of the Iranian Navy, attended the ceremony. The Jamaran 2, which is a destroyer of the Moj class, has been designed and manufactured by experts at the Marine Industries Organization of the Iranian Defense Ministry. The warship can carry helicopters and is equipped with advanced radar systems, electronic warfare systems, artillery and anti-aircraft guns, torpedoes, and surface-to-surface and surface-to-air missiles. At the ceremony, the defense minister said that the Jamaran 2 would be used to guard the country’s sea borders and back up operations to combat human and drug smuggling. It is about 100 meters long and weighs over 1,300 tons, Vahidi said.In addition, he said that the destroyer would undergo final tests over the next three months and would join the Navy in the first half of the next Iranian calendar year, which starts on March 21. Iran’s first domestically manufactured destroyer, the Jamaran, was launched in February 2010. The Sahand destroyer was also launched in September 2012. The Iranian Navy has also announced that it plans to build seven destroyers of the Sina class, which are capable of firing missiles.

HMS Diamond exercises with her French counterpart*
Originally conceived under the same project that envisaged a single design for the British, French and Italians Navies, the UK subsequently decided to pursue its own design, the Type 45, but there are still many similarities between the two.
HMS Diamond met up with the FS Forbin while on her way to the Middle East where she will be working to protect the seas, keeping them safe for international trade.
As specialist air defence platforms, both ships engaged in exercises that saw them defend themselves against attacking jets flown from the French aircraft carrier, FS Charles de Gaulle.
This scenario reflected what both HMS Diamond and FS Forbin are primarily designed to deal with if they were escorting a task group of warships, and it allowed them to engage with multiple aircraft and simulated missile runs.
Captain Marc Assedat, the Commanding Officer of the Forbin said:
"Speaking openly and sharing each other’s experiences strengthens our confidence.”
Having left her home port of Portsmouth on 13 June and already called in at Gibraltar, Diamond continues to the Middle East, where she will take on her operational duties from her sister ship, HMS Daring, protecting UK interests in the region.

HMS Defender completes final set of sea trials*

The UK Royal Navy's fifth Type 45 destroyer HMS Defender (D36) has successfully completed its second and final set of sea trials off the west coast of Scotland.
During the second sea trials, the frigate engines, communications, combat systems and sensors were validated.
HMS Defender is undergoing three months of final testing and checking of systems ahead of its formal delivery to the Navy in July 2012.
Defender's first sea trials were carried out in 2011 to validate its speed, manoeuvrability, power and propulsion systems as well as weapons systems and sensors.
The newest £1bn Type 45 class destroyer has a displacement capacity of about 8,000t with a cruising speed of more than 27k and a range of over 7,000nm.
The frigate features the Sea Viper missile system, which is capable of defending against multiple attacks by sophisticated anti-ship missiles.
HMS Defender has a range of capabilities including air defence, anti-missile capabilities, and the ability to carry 60 Royal Marines as well as operating a Chinook-sized helicopter from the main decks.
The advanced air-defence warship is also capable of performing anti-piracy and anti-smuggling missions, disaster-relief work and surveillance operations as well as high-intensity war-fighting.
The sixth Type 45 destroyer, HMS Duncan, launched in 2010, is under final stages of completion at Scotstoun while the fourth destroyer Dragon, launched in Scotland in 2008, is currently undergoing training and trials prior to its maiden deployment.
HMS Daring, the first destroyer in the class, has been recently deployed, while Dauntless and Diamond are ready for deployment later this year.
HMS Defender frigate is scheduled to be operational from early 2013.
