De facto, não se entende porque é que não adquirem navios patrulha de construção portuguesa, como os recém adquiridos pela GNR. O mesmo se aplica a aeronaves, já que podiam perfeitamente ter adquirido aviões de patrulha marítima de fabrico português. Os Viana do Castelo são claramente um desenho superior e, certamente, mais versátil que está coisa francesa..

Os estaleiros do alfeite tem bons desenhos, quanto aos aviões, acredito que as OGMAs consigam converter um avião em vigilância.

O Alfeite tem esboços de projectos, e neste momento não tem capacidade para nada, até para construirem uma "simples" lancha de salvamento com aspeto tosco estão atrasado mais de 1 ano.

E as OGMAs já leu o relatório do acidente daquele Embraer que esteve para amarar no Tejo e acabou por aterrar em Beja? Há oficinas de carros com mais procedimentos de segurança.

NAVSEA Builds New Frigate Readiness Digital Model In Advance Of Construction
Even before the hull of the first new Constellation-class Frigate (FFG), USS Constellation (FFG 62), is laid, a cross-warfare center team is developing a digital platform to predict whether its systems are ready for its mission before it leaves port.

WE Tech to provide WE Drive for Finnish Navy Squadron 2020 corvettes
by Richard Scott

Finnish company W Tech has received a contract to supply its WE Drives to control the RENK advanced electric drives to be used on the four new Pohjanmaa-class corvettes being procured by Finland under the Squadron 2020 corvette programme.

Announcing the contract on 17 May, W Tech said its W Drives will ensure the smooth operation of the corvettes' combined diesel-electric and gas (CODESLAG) propulsion in different operating modes.

This is our first military navy project and marks an important milestone for W Tech Solutions, said company CEO Mårten Storbacka.

RENK's parent company MAN Energy Solutions is responsible for the overall integration of the electric propulsion and gearbox system of the Squadron 2020 vessels. For the CODELAG propulsion, it is supplying four MAN 12V 175D diesel engines that can produce a total of 30 MW or 40,000 hp for speeds of up to 26 kt. For speeds above that figure, a single General Electric LM2500 gas turbine will drive both shaft lines to the twin CPPs. The range of the vessels will be about 3,500 n miles or 6,500 km.

The WE Drives will be delivered to RENK's Augsburg facility for integration.

Once in service the Pohjanmaa-class corvettes will be the Finnish Navy's largest combat vessels since the 1930s. The ships will displace 3,900 tonnes, with an overall length of 114 m, a 16 m beam, and a maximum draught of 5 m. They will carry a crew complement of 70 officers, ratings and cadets. Their year-round deployment in the Baltic region requires strengthening equivalent to Ice Class 1A.

Iranian Navy Commissions A New Minesweeper And A Light Frigate

The light frigate Dena (hull number 75) and minesweeper Shahin (hull number M111) were commissioned at a ceremony at the main Iranian naval base in Bandar Abbas port, located in the Strait of Hormuz.




The 1,500 ton light frigate ‘Dena’ is Iran’s fourth Project Mowj built. The project has been considerably delayed since the 2000s, specially bacause of the need to replace some components due to sanctions. The ships of the project are built with some notable differences from each other, while the main armament in general remains the same. Like its predecessors, Dena carries four Noor or Ghader SAM launchers, two Mehrab antiaircraft missile launchers, two three-tube 324-mm torpedo launchers, and a 76-mm Fajr 27 artillery gun. In addition, the ship is fitted with light 23mm artillery and a 40mm Fath artillery unit.



As previously reported by Naval News, Shahin is Iran’s head of class of a new composite hull minesweepers currently under construction. It will bring new capabilities to the Iranian Navy. This is despite both the Iranian Navy and IRGC (Islamic Revolutionary Guards Corps) making extensive use of sea mines.

The adoption of an SES for mine warfare isn’t unique. The Royal Norwegian Navy’s Oksøy and related Alta classes use this technology. They are larger however and use plastic hulls, unlike the Shahin which is constructed out of steel.

Talvez já tenha colocado este texto... mas tenho andado a pensar nele, que o diabo está nos detalhes.

This Deficiency Is Keeping European Naval Strategists Up At Night

The problem? European warships don’t carry as many missiles as their American and Asian counterparts. More specifically, their vertical launch systems (VLS), which consist of dozens of cells that each contain a missile, don’t have as many cells as the VLS on U.S. and Asian warships.

“One striking differential in terms of European navies’ capabilities concerns VLS capacity,” writes Nick Childs, a researcher for the London-based International Institute for Strategic Studies. “Most European platforms are built around a maximum forty-eight-cell VLS capability for their principal weapons systems. U.S. ships accommodate at least ninety cells, rising to 122 on the Ticonderoga. Japan’s ships likewise sport some ninety cells, while South Korea’s latest ships have eighty. The PLAN’s [Chinese navy’s] Type-052Ds host sixty-four cells for their principal weapons and the Type-055s 112. Clearly, such numbers have significance in terms of being able to sustain operations in a high-intensity confrontation. Given the difficulties of resupply, particularly at sea, it also has implications for those European navies, particularly the British and French, contemplating long-range deployments, such as to the Indo-Pacific.

Childs dates the advent of the U.S. Navy’s Aegis air defense system in the 1980s as a turning point. “It comprised phased-array radars and an integrated combat system, as well as better surface-to-air missiles, to improve processing, reaction time and channels of fire, and to provide an extended engagement envelope. Shortly after, as a further significant enhancement, came the introduction of the multiple-cell vertical launch system (VLS) in place of trainable twin-arm missile launchers,” he notes.

Europe followed suit, though building more sophisticated ships resulted in fewer ships being built, says Childs. But ships like France’s Forbin-class, and Australia’s Spanish-designed Hobart-class destroyers, have just VLS tubes.

Asian navies have chosen to follow the U.S. model of Aegis ships packing numerous VLS launch cells. “The most significant recent advances, however, have been in Asian navies,” says Childs. “This has included the introduction into the navies of Japan and South Korea (and soon also the Chinese People’s Liberation Army Navy (PLAN), in the shape of the Type-055) of vessels in the cruiser class, at 10,000 tons or more full-load displacement, rivaling the US Ticonderoga-class cruisers in size.”

Ships with plentiful VLS anti-aircraft missiles significantly enhance the ability of Asian navies to form well-balanced task forces. Nonetheless, Childs counts the U.S. Navy as having 8,720 VLS cells on its Ticonderoga- and Arleigh Burke-class ships, compared to 864 on China’s Type 052C and D destroyers.

Nor is it clear if China’s Aegis equivalent is as good as America’s. “On the face of it, these are highly-capable units, although there are still question marks over the performance of their combat systems, radars and weapons relative to, for example, the latest baseline Aegis systems,” Childs notes.

Russia is replacing multiple VLS models with a single universal VLS that can be fitted to different classes of warships, including cruisers, corvettes and submarines. However, Russian critics warn that a planned supersized version of the Kalibr cruise missile won’t fit in existing VLS cells.

There is no doubt that VLS has significantly changed naval warfare. Before the 1980s, missile launchers could fire one or two missiles at a time, which then had to be slowly reloaded from the ship’s magazine. Having a hundred or more missiles in VLS cells ready to fire vastly increases a ship’s firepower, though reloading the cells is a problem (the U.S. Navy is looking for ways to reload VLS cells at sea).
