GE to Provide LM2500 Gas Turbines for Finnish Navy's Pohjanmaa-class Corvettes    ( toch de keuze voor Gasturbines en geen diesel/electric )

GE Marine announced it has received a contract from Rauma Marine Constructions, Rauma, Finland, to provide four LM2500 marine gas turbines. These reliable GE engines will power four new Pohjanmaa class multipurpose corvettes to be built as part of the Finnish Navy's Squadron 2020 Project.

"The LM2500s will be equipped with GE's new composite gas turbine module which was of particular interest for this application. The new enclosure offers a significant reduction in weight over its steel predecessor, and most importantly, a safer environment and improved access for sailors," Shepherd added.

Pohjanmaa class corvettes are designed for year-round service in the seasonally freezing Baltic Sea, and will have the ability to operate independently in ice. Each 3,900-ton corvette will feature one GE LM2500 gas turbine in a Combined Diesel eLectric And Gas turbine (CODLAG) configuration to reach speed in excess of 26 knots. GE also will provide a full complement of gas turbine auxiliary systems including electric start and water mist firefighting systems, fuel forward and water wash skids, and controls.
The LM2500 gas turbines will be Made in the U.S.A. at GE's manufacturing facility in Evendale, Ohio. Construction of the corvettes by the shipyard is slated to begin in 2022; all ships are expected to be delivered to the Finnish Navy by 2026 and fully operational in 2028.

With a GE gas turbine, navies have worldwide support whether onshore or at sea, and interoperability benefits with other allied ships. GE has delivered gas turbines onboard 646 naval ships worldwide and provides 97% of the commissioned propulsion gas turbines in the United States Navy fleet. With GE's split casing compressor and power turbine design, in-situ maintenance is allowed, often making a gas turbine removal unnecessary; navies save millions of dollars a year and weeks/months of ship unavailability.

Daarom Oto Marlin 40mm of Bofors Mk4: 300rds per minute!

200 of 300rds is nog steeds te langzaam en 40mm heeft te weinig massa om effectief te zijn met airburst munitie (tegen inkomende missiles.

Mach 8.... afborrelen maar.

Die mach 8 halen die Russische raketten enkel als ze buiten de atmosfeer zijn, wanneer ze weer op zeeniveau vliegen gaan ze net zo snel (of langzaam) als conventionele raketten.
Om mach 8 te vliegen en bijsturen op zeeniveau is van een geheel andere orde, dat kunnen ze niet. Dan komt er ook zoveel wrijving, warmte op zo'n raket dat deze of weg smelt of ontbrandt als een lucifer.

Het is niet voor niets dat de SR-71 Blackbird enkel >mach 3 kon vliegen op 80.000 ft.

Met een vuursnelheid van slechts 200 rds/min en 40mm CTA ga je het niet redden tegen een moderne missile.
Het is een beetje de grote broer van onze 30mm Marlins.

France to arm future OPVs with RAPIDFire Naval CIWS

09 OCTOBER 2020

by Victor Barreira

The 10 offshore patrol vessels (OPVs) to be acquired for the French Navy under the Patrouilleurs Océanique (PO) programme will be armed with the Thales/Nexter RAPIDFire Naval multirole close-in weapon system (CIWS), Commander Ghislain Deleplanque, head of the French Navy's Protection & Safeguarding Office, Future Naval Programs, revealed during the Defence iQ's OPV International online conference.

The PO programme was formally launched in June by the French Ministry of the Armed Forces, with design activity currently being carried out by Naval Group. An acquisition and construction contract has yet to be placed.

The RAPIDFire Naval CIWS developed by Thales and Nexter comprises a non-penetrating gun mount fitted with the CTA International 40CTAS (40 mm Cased Telescoped Ammunition System) and an optronic fire-control system, an ammunition magazine for around 140 ready-to-fire rounds, gun control equipment and an automatic ammunition handling system. It can function either in an integrated or autonomous mode.

The gyrostabilised gun has a firing rate up to 200 rds/min with a typical burst against air threats of up to 10 anti-aerial air burst rounds, and an effective range up to 4,000 m and up to 2,500 m against surface threats using point detonating, air burst, and armour-piercing fin-stabilised discarding sabot rounds.

The 10 OPVs are scheduled to be commissioned between 2025 and 2029. They will have an overall length of around 90 m, a displacement of around 2,000 tonnes, and will carry a crew complement of 40.

South Korean military aiming to speed up acquisition of light aircraft carrier

08 OCTOBER 2020

by Gabriel Dominguez

Amid the growing naval capabilities of neighbouring countries, South Korea's Joint Chiefs of Staff (JCS) have requested that construction plans for the Republic of Korea Navy's (RoKN's) next-generation light aircraft carrier be brought forward.

Officials from the Ministry of National Defense (MND) in Seoul told Janes on 8 October that the JCS want the carrier's basic design to be included in the MND's Defense Mid-Term Plan covering the period from 2021–25, meaning that design work could start as early as next year.

According to RoKN data, completion of the basic design will take about three years, with a further seven years required for the detailed design and construction, meaning that the carrier could be ready for delivery as early as 2031. Depending on how long the sea trials period takes, the carrier could be operational between one and two years earlier than initially planned.

The 30,000–35,000 tonne carrier, which is being acquired under the LPX-II project, is expected to support operations of helicopters and short take-off and vertical landing (STOVL) aircraft such as the Lockheed Martin F-35B Lightning II Joint Strike Fighter.

This means that the MND will also try to speed up the introduction of STOVL fighter aircraft, with MND officials telling Janes that the procurement process for the fighters is expected to begin "in earnest" next year. The RoKN is believed to have an initial requirement for about 20 such aircraft.

While the exact type of STOVL aircraft has yet to be determined, the Yonhap News Agency reported in August that it is likely to be the F-35B, adding that it is the only model that meets the RoKN's requirement.

Japan's converted Izumo-class carriers will not feature a 'ski-jump' ramp for F-35B operations

08 OCTOBER 2020

by Kosuke Takahashi

The Japan Maritime Self Defense Force (JMSDF) has decided that its two Izumo-class helicopter carriers will not be fitted with a 'ski-jump' ramp to facilitate operations of the short take-off and vertical landing (STOVL) F-35B Lightning II Joint Strike Fighter, Janes has learnt.

Instead, each vessel will have the bow section of its flight deck, which is currently trapezoidal, modified into a square shape, similar to that found on the United States Navy's Wasp- and America-class amphibious assault ships.

This change will enable the ship to safely operate the F-35Bs by mitigating turbulence during take-offs and enabling the aircraft to take off and land on the port side of the flight deck, maintaining a safe distance from the ship's island, a JMSDF spokesperson told Janes on 8 October.

He also confirmed that the modifications to JS Izumo and JS Kaga will be made in two main stages to coincide with the vessels' periodic refit and overhaul programmes, which take place every five years

As Janes reported in June, the service has already begun the process of converting Izumo

Hanwha Systems Selected as Preferred Bidder for KDDX's CMS and I-MAST    ( I-MAST..  waar heb ik dat eerder gezien .. copy and paste van Thales ..(lijkt het wel ) 

South Korea's Hanwha Systems has been chosen as the preferred bidder for the KDDX Combat Management System (CMS) and Multi-Function Radar (MFR) developments and production. KDDX is the Republic of Korea (ROK) Navy next generation destroyer program.

Hanwha Systems announced on September 16th that it was selected as the final preferred negotiator for KDDX's Combat System (CMS) and Multifunctional Radar (MFR) Development' project. The scale of the business is about 670 billion won, accounting for about 60% of Hanwha Systems' defense division sales in the previous year.

Hanwha Systems was competing against another local company: LIG Nex1. If finalized, Hanwha Systems will be simultaneously developing critical components for several major Korean defense programs: The FFX Batch-III frigate, the KF-X stealth fighter, the L-SAM long range surface-to-air missile system, and KDDX.

According to the company's press release, the combat system is a strategic weapon system for integrated operation of various sensors, armament, and other communication and command systems fitted on a ship, and is a core system that acts as the ship's brain.

The combat system to be installed aboard the KDDX destroyer will perform the role of command and control of ships' weapons in simultaneous combat situations such as anti-air warfare (AAW), anti-surface warfare (ASuW), electronic warfare (EW), and land attack. It will integrate, link, and analyze resources such as sensors and armaments based on a network, and will be equipped with real-time tactical information processing technology and multiple data links to control various guns and guided missiles.

The company added that the integrated mast (I-MAST), a new concept sensor system that improves the stealth capability of ships, includes detection sensors such as dual-band multi-function phase array radar, infrared detection and tracking equipment (IRST), and identifier (IFF), and communication devices such as VHF/UHF. The antennas flat and all fitted on a single mast.

Hanwha Systems has been studying the possibility of applying integrated masts for the past 10 years and securing stealth design technology. It has developed and installed Korea's first complex sensor mast (MFR+IRST integration) and the world's first 100% digital multi-functional active phase array radar in a four-sided fixed type on the Ulsan-class FFX Batch-III which currently being tested.

The multi-function radar to be installed in KDDX is a dual band multi-function radar. It combines
•Two S-Band antennas for detecting and tracking long-range air targets and ballistic missiles
•Two X-Band antennas for detecting and tracking short-range air targets and surface targets

The X-Band radar is the same radar as the AESA radar of the recently unveiled Korean fighter (KF-X). In addition, Hanwha Systems already has expertise in simultaneous S-band and X-band radar operation, the core technology of 'dual-band multi-function radar' and the ability to develop full digital transmission and reception block (DTRB) technology.

De nieuwe fregatten zien er nogal anders uit dan we gewend waren.

Ik zou me niet al te vastpinnen aan dit ontwerp, als je kijkt naar de begin ontwerpen van de nieuwe Spaanse ASW fregatten (F110) en wat er uiteindelijk gebouwd gaat worden is dat ook helemaal anders.

[Parera]

Als onderdeel van PESCO is Spanje gestart met het ontwikkelen van (sub) systemen voor de generatie fregatten die vanaf 2035 in dienst moeten komen. Ze richten zich voornamelijk op een AAW destroyer (7000 t), een ASW fregat (6000 t) en een multipurpose fregat (5000 t). Als eerste project word het eigen F-120 fregat genoemd, de waarschijnlijke opvolger van de Álvaro de Bazán klasse AAW fregatten maar ook andere (Europese) fregatten.
