Aegis equipped ship

According to Naval News, 19 March, 2021, the Japan Maritime Self-Defense Force (JMSDF) held the Ship Commissioning ceremony of the JS Haguro (DDG-180) at Yokohama Shipyard, Japan Marine United Corporation. She is named after Mt. Haguro of Yamagata Prefecture.

Japan commissions new Maya-class AEGIS destroyer JS Haguro (DDG-180)

JS Haguro (DDG-180) is the second and final vessel of the Maya-class of destroyers. It is also the eighth Aegis destroyer of the JMSDF. Her keel was laid in January 2018 and she was launched on July 17th 2019. First ship-in-class, JS Maya (DDG-179) was commissioned on March 19 2020. The new class of destroyers comes with ballistic missile defense (BMD) capabilities. Each unit costs around US $1,5 Bn and were being built at the Japan Marine United Corporation’s (JMU’s) shipyard at Isogo Ward in Yokohama.

The Maya-class will be limited to just two ships. The next Japanese vessels to feature Aegis are the still unspecified «Aegis equipped ships» that will likely be ordered as a consequence to the cancelation of Aegis Ashore.

Like her sister-ship, the vessel is named after a mountain: Mount Haguro (Haguro-san). The previous vessel to bear this name was the famous heavy cruiser Haguro of the Imperial Japanese Navy. Commissioned in 1929, Haguro saw significant service during World War II, participating in nine naval engagements. She was sunk in 1945 during a fight with Royal Navy destroyers, one of the last major Japanese warships to be sunk in open waters during World War II.

Contrary to JS Maya (DDG-179) Haguro’s hull number is painted in low visibility.

Originally known as 27DDG (this means that she was built in the FY2015 budget), this new project of improved Aegis destroyers started in 2015. The new destroyer class is 170 meters/558 feet long and displaces standard 8332 tons (10,414 tons full load). She operates with a crew of 310 sailors, and features a COmbined Gas turbine-eLectric And Gas turbine (COGLAG) propulsion system.

This new destroyer class will be limited to two units named after famous mountains in Japan: The first ship-in-class, JS Maya (DDG-179), had its keel laid in April 2017, was launched on July 30th 2018 and commissioned with the JMSDF on 19 March this year. Its sistership, JS Haguro (DDG-180) had its keel laid in January 2018, was launched on July 17th 2019 and is currently conducting sea trials.

Each ship costs around US $1,5 Bn and both were being built at the Japan Marine United (JMU) shipyard at Isogo Ward in Yokohama. The Maya-class is the first of JMSDF’s Aegis destroyers fitted with Ballistic Missile Defense (BMD) capabilities from the design stage, and is also the first of Japan’s AEGIS fleet to be equipped with Cooperative Engagement Capability (CEC) from the start. The CEC allows the ship to receive targeting information from other assets, such as U.S. Navy and Royal Australian Navy AEGIS destroyers or American and Japanese E-2D AEW&C aircraft. Japan has four E-2D Advanced Hawkeye aircraft on order, with the first one delivered on March 29 to the Japan Air Self-Defense Force.

Fitted with the AEGIS Baseline J7 combat system, the AN/SPY-1D(V) passive electronically scanned array radar and the AN/SPQ-9B surface search radar, the Maya-class destroyers is able to fire the latest iteration of Raytheon’s SM-3 ballistic defense missile. Being jointly developed by the U.S. and Japan, the SM-3 Block IIA features larger rocket motors that will allow it to defend broader areas from ballistic missile threats and a larger kinetic warhead.

The Maya-class features 96 cells of Mk41 VLS (64 cells forward and 32 cells aft). Other weapon systems of the Maya-class include:

  • SM-6 also known as RIM-174 Standard Extended Range Active Missile (ERAM);
  • SM-2MR Block IIIB Surface to Air Missiles;
  • Type 07 Vertical Launch Anti-submarine rocket;
  • Type 90/17 anti-ship missiles;
  • Mk 45 Mod 4 127-mm main gun;
  • 2x Phalanx Close-In Weapon System (CIWS);
  • 2x HOS-302 triple torpedo tubes (for Mk-46 or Type 73 torpedoes).

The SM-6 is a multi-mission missile that can engage both air and surface targets. According to our Japanese sources, SM-6 was scheduled to be procured in Japan’s defense budget of FY2019, but procurement was postponed due to shortage of SM-6 parts in the United States. Japan is set to become the first export customer of this missile type. SM-6, SM-3 and SM-2 are all designed and produced by Raytheon.

As we reported recently, the Maya-class destroyers will feature a cooperative table developed by Japanese company Fujitsu. Placed in the CIC, this table will be used for mission planning, among other tasks.

For electronic warfare, the Maya-class is fitted with NOLQ-2C Electronic Support Measures and Mk.137 decoy launchers. The Maya-class is not fitted with any Electronic CounterMeasures (ESM) system.

For anti-submarine warfare, the Maya-class is equipped with an AN/SQS-53C bow sonar and a Multi-Function Towed Array (MFTA) sonar at the stern.

Last but not least, the Maya-class would typically deploy with an SH-60K maritime helicopter.

Offshore Patrol Ship

On March 13, 2021, the launch of the third Multipurpose Offshore Patrol ship (PPA) «Raimondo Montecuccoli» took place at Fincantieri’s shipyard in Riva Trigoso (Genoa).

The ceremony, held in a restricted format and in full compliance with anti-contagion requirements, was attended by Senator Stefania Pucciarelli, the Italian Undersecretary of Defence representing the Minister Lorenzo Guerini, Admiral Eduardo Serra, Italian Navy Logistic Commander, and Giuseppe Giordo, General manager of the Naval Vessel division of Fincantieri.

Godmother of the ship was Mrs. Anna Maria Pugliese, daughter of Admiral Stefano Pugliese, who was Commander of the light cruiser «Montecuccoli», which entered into service in 1935 and was uncommissioned from the Italian Navy fleet in 1964.

This vessel, third of seven, will be delivered in 2023 and it is part of the renewal plan of the operational lines of the Italian Navy vessels, approved by the Government and Parliament and started in May 2015 («Naval Act») under the aegis of OCCAR (Organisation Conjointe de Cooperation sur l’Armement, the international organization for cooperation on arms).


Vessel’s characteristics: PPA – Multipurpose Offshore Patrol Ship

The multipurpose offshore patrol vessel is a highly flexible ship with the capacity to serve multiple functions, ranging from patrol with sea rescue capacity to Civil Protection operations and, in its most highly equipped version, first line fighting vessel. There will be indeed different configurations of combat system: starting from a «soft» version for the patrol task, integrated for self-defence ability, to a «full» one, equipped for a complete defence ability. The vessel is also capable of operating high-speed vessels such as RHIB (Rigid Hull Inflatable Boat) up to 11 meters long through lateral cranes or a hauling ramp located at the far stern.

  • 133 meters/436 feet long
  • Speed more than 31 knots/36 mph/57 km/h according to vessel configuration and operational conditions
  • 171 persons of the crew
  • Equipped with a combined diesel, a gas turbine plant (CODAG) and an electric propulsion system
  • Capacity to supply drinking water to land

The Multipurpose Offshore Patrol ships will be built at the Integrated Shipyard of Riva Trigoso and Muggiano, with deliveries expected until 2026.


Raimondo Montecuccoli, from Modena, was a general in service within the Austrian Empire. He participated with great success in all the wars fought in Europe – between 1625 and 1675 – by the Habsburg monarchy against the Dutch, Swedes, Turks and French. Initiated to a career in the church, he instead chose the military career with determination, serving the Empire and standing out in several campaigns during the Thirty Years’ War. From 1648, he held a series of very important diplomatic positions in Italy and Europe. At the peak of his career, he became the rank of General Lieutenant of the Empire (1609-1681).

He was a man with a unique culture, a very successful military writer (he was the first to further explore his studies in personnel and logistics), and was mentioned by Ugo Foscolo as the greatest and most learned Italian men at arms.

His name was previously attributed to a light cruiser of the same-named class. Unit characterized by the reputation of a lucky ship, in the headlines since 1937, when she was sent, with only twenty-four hours notice, to China. Protagonist of the battle of Pantelleria, on June 15, 1942, the vessel resulted in the loss of the destroyer «Bedouin», the «Kentucky» tank, as well as in the damage to the cruiser «Cairo», the destroyers «Ithuriel» and «Partridge», and the minesweeper «Hebe».

Logistic Support Ship

On March 12, 2021, the logistic support ship LSS «Vulcano», ordered to Fincantieri within the renewal plan of the Italian Navy’s fleet, was delivered by the Naval Integrated shipyard in Muggiano.

Vulcano (A5335)
Fincantieri delivers LSS «Vulcano» for Italian Navy in Muggiano

The multi-year program for the renewal of the Italian Navy’s fleet foresees the construction, besides the LSS, of the transport and landing unit LHD (or Landing Helicopter Dock) «Trieste» – under construction in this same shipyard with delivery in 2022 – as well as seven Multipurpose Offshore Patrol Ships (PPA), which will enter the fleet starting this year.

The fundamental characteristic common to all three classes of ships is their high level of innovation providing them with a considerable degree of efficiency and flexibility in serving different mission profiles. In particular, these are dual use vessels, meaning that they may be used for both standard military purposes and those in favor of the community (as for example for civil protection), and they also have a low environmental impact thanks to a state-of-the-art auxiliary propulsion system generating a low level of pollution emissions (electric engines).

The project of «Vulcano» underlies the FLOTLOG («Flotte Logistique») program, consisting in the construction of four LSS destined to the French Navy, by the temporary consortium between Chantiers de l’Atlantique and Naval Group under the Italian-French LSS Program led by OCCAR (Organisation for Joint Armament Co-operation). The construction of the forward sections of these ships has been commissioned to Fincantieri, which last month has laid the keel of the first vessel at its shipyard in Castellammare di Stabia (Naples).

The vessel «Vulcano» is classified by RINA pursuant international conventions about prevention of pollution regarding the more traditional aspects, like the ones of the MARPOL Convention, as well as those not yet mandatory, as the Hong Kong Convention about ship recycling.


Vessel’s characteristics – LSS – Logistic Support Ship

The LSS is a vessel that provides logistics support to the fleet, endowed with hospital and healthcare capabilities thanks to the presence of a fully equipped hospital, complete with operating rooms, radiology and analysis rooms, a dentist’s office and hospital rooms that will be capable of hosting up to 17 seriously injured patients. The ship combines capacity to transport and transfer to other transport vessels used for liquids (diesel fuel, jet fuel, fresh water) and solids (emergency spare parts, food and ammunitions) and to perform at sea repairs and maintenance work for other vessels. The defense systems are related to the capacity of command and control in tactical scenarios, communications and dissuasive, non-lethal defense systems. The vessel is also capable of embarking more complex defence systems and becoming an intelligence and electronic war platform.


  • 193 meters/633 feet long
  • speed of about 20 knots/23 mph/37 km/h
  • 235 persons including crew and specialists
  • 4 replenishment station abeam and 1 astern
  • Capacity to supply drinking water to land
  • Capacity to provide electricity to land with 2500 kw of power
  • Possibility of embarking up to 8 residential and healthcare modules
  • Capacity to perform rescues at sea, through recovery and seabed operations (the ship is equipped with a 30 tons offshore stabilized crane stabilized)
  • base for rescue operations through helicopters and special vessels

Third Kalvari Class

Indian Navy’s third stealth Scorpene class Submarine INS Karanj (S23) has been commissioned on March 10, 2021 at the Naval Dockyard Mumbai through a formal commissioning ceremony. Admiral VS Shekhawat PVSM, AVSM, VrC (Retd), former Chief of the Naval Staff, who was part of the commissioning crew of the old Karanj and later the Commanding officer during the 1971 Indo – Pak war, was the Chief Guest for the ceremony. Six Scorpene Class submarines are being built in India by the Mazagon Dock Shipbuilders Limited (MDL) Mumbai, under collaboration with M/s Naval Group, France. INS Karanj (S23) would form part of the Western Naval Command’s Submarine fleet and would be another potent part of the Command’s arsenal.

Admiral Karambir Singh, Chief of the Naval Staff, and other senior officers from the Indian Navy and MoD were amongst the several dignitaries who witnessed the commissioning ceremony. Crew of the erstwhile ‘Karanj’, a Russian origin Foxtrot Class Submarine which was decommissioned in 2003 were also special invitees for the ceremony. During his address, the CNS said «this impetus to Indigenisation & AatmaNirbharBharat is a fundamental tenet of Indian Navy’s growth story and future operational capabilities».

The Chief Guest Admiral Shekhawat also highlighted India’s push towards AatmaNirbharta by saying «we live in an India launching numerous satellites, building nuclear submarines, manufacturing vaccines for the worlds – the new Karanj is another example of it».

This year is being celebrated as the ‘Swarnim Vijay Varsh’ which marks 50 years of 1971 Indo – Pak war. Old INS Karanj, commissioned on 04 Sep 1969 at Riga in the erstwhile USSR, also took active part in the conflict under the Command of then Cdr VS Shekhawat. In recognition of the valiant action of her officers and crew, a number of personnel were decorated, including award of Vir Chakra to the then Commanding Officer Cdr VS Shekhawat. Interestingly, the commissioning Commanding Officer of the old INS Karanj Cdr MNR Samant later on became the first Chief of The Naval Staff of the newly formed Bangladesh Navy in the year 1971.

The Scorpene Submarines are one of the most advanced conventional submarines in the world. These platforms are equipped with the latest technologies in the world. More deadly and stealthier than their predecessors, these submarines are equipped with potent weapons and sensors to neutralise any threat above or below the sea surface.

The induction of INS Karanj (S23) is another step towards the Indian Navy, consolidating its position as a builder’s Navy, as also is a reflection of MDL’s capabilities as a premier ship and submarine building yard of the world. Project – 75 also marks a critical milestone in the Yard’s continued importance in the field of Defence Production.

The OPV Enterprise brings together Commonwealth and defence industry teams under one roof, to build and sustain the Royal Australian Navy’s new Arafura Class OPVs, the first two of which are being constructed in South Australia, with the remaining 10 vessels to be built in Western Australia.

«It is great to see the co-location of Commonwealth shipbuilding and sustainment personnel and Luerssen, CIVMEC and Raytheon industry partners delivering outcomes for our Navy», said Deputy Secretary National Naval Shipbuilding, Mr. Tony Dalton.

Head Maritime Systems, Rear Admiral Wendy Malcolm said the establishment of the OPV Enterprise represented an important milestone under the Continuous Shipbuilding Plan.

«The launch marks a critical step towards the implementation of Plan Galileo, an ambitious Future Maritime Sustainment Model which ensures our sustainment organisation engages with acquisition teams early in the build process», Rear Admiral Malcolm said. «Evolution of our asset management, supply chain, infrastructure, improved commercial models and professionalisation across the enterprise will be key to success. This process ensures sustainment needs are considered during the design phase, and brings together Defence, primes, small business and service providers to facilitate sustainment of our naval vessels from strategically located ports around the country. Not only does this promise to deliver long-term jobs to West Australians and confidence for industry to invest in Perth, but it will ensure our Navy is able to meet all Government tasking in order to protect our nation’s security».

The Arafura Class OPVs, which replace the Armidale and Cape Class patrol boats, will be the Australian Defence Force’s main asset for maritime patrol and response duties and will primarily undertake constabulary missions.


Huntington Ingalls Industries (HII) announced on March 3, 2021 that the Virginia-class submarine USS Montana (SSN-794) was launched into the James River at the company’s Newport News Shipbuilding division.

The 7,800-ton submarine, which had been in a floating dry dock since being transferred from a construction facility in October, was submerged and moved by tugboats to the shipyard’s submarine pier, for final outfitting, testing and crew certification.

«For our shipbuilders, launching Montana signifies five years of hard work, commitment and dedicated service», said Jason Ward, Newport News’ vice president of Virginia-class submarine construction. «We look forward to executing our waterborne test program, and working toward sea trials and delivering the submarine to the U.S. Navy later this year».

Through the teaming agreement with General Dynamics Electric Boat approximately 10,000 shipbuilders, as well as suppliers from all 50 states, have participated in Montana’s construction since the work began in 2015. Montana is approximately 92% complete and scheduled to be delivered to the U.S. Navy in late 2021.

Virginia-class submarines, a class of nuclear-powered fast attack submarines, are built for a broad spectrum of open ocean and littoral missions to replace the Navy’s Los Angeles-class submarines as they are retired. Virginia-class submarines incorporate dozens of new technologies and innovations that increase firepower, maneuverability and stealth and significantly enhance their warfighting capabilities. These submarines are capable of supporting multiple mission areas and can operate at submerged speeds of more than 25 knots for months at a time.
