Perman Posted March 12 Report Share Posted March 12 (edited) Trots ett omfattande samarbete på flygsidan mellan Brasilien och Saab så tycks det inte bli nåt köp av svenska minröjningssystem. Det har under säkert ett decennium spekulerats om Brasilien skulle beställa svenska minröjningsfartyg av Landsort/Koster typ för att ersätta sina nu nästan antika f d kustminsvepare av tyska Schütze-klassen från 70-talet. Trots att de genomgick en livstidsförlängning 2001-07 så finns nu bara tre enheter kvar i tjänst av de ursprungliga sex. En möjlig interimslösning som det också spekulerats om har varit om Brasilien skulle köpa de gamla minjaktfartygen LDO och ARH som länge legat i malpåse i Karlskrona. Nu har man annonserat planer om att anskaffa 11 OPV fartyg på 500 ton från företaget Emgepron. Åtta av dessa OPV kommer att ha övervakning och skydd av EEZ zonen, SAR, och bekämpning av illegala verksamheter som t ex illegalt fiskeri. De sista tre kommer att vara utrustade för minröjningsoperationer. Därmed så kan vi nog lägga ned ev. förväntningar på något samarbete med Sverige och Saab när det gäller minröjning. Quote As reported by Brazil Defense Brief (BDB) on February 24, 2025, the Brazilian Navy's Naval Systems Design Center (CPSN) delivered the basic engineering plan for the 500-ton offshore patrol vessel (NPa500MB) to Emgepron, a state-owned company responsible for naval projects, in late January. This step is part of the Patrol Vessel Acquisition Program (PRONAPA), which involves the domestic construction of 11 offshore patrol vessels (OPVs) with a high percentage of locally sourced components. These vessels are designed for the surveillance and protection of the Exclusive Economic Zone (EEZ), search and rescue operations, and combating illegal activities such as illegal fishing. Quote The NPa500MB is equipped with a Bofors Mk4 40 mm multipurpose gun at the bow and two Oerlikon GAM-B01 20 mm machine guns amidships. The vessel's Combat Management System integrates navigation and surface search radars, an optronic sensor suite, X-band satellite communication, and a TV/streaming reception system for long-duration patrols. The vessel's specifications include an overall length of 58.9 meters, a beam of 9.0 meters, a maximum draft of 2.5 meters, and a displacement of 564 tons when fully loaded. It has a steel hull and an aluminum superstructure. The propulsion system consists of two diesel engines driving two shaft lines, achieving a sustained top speed of 21.7 knots and a service speed of 13 knots. The vessel has an operational range of 3,000 nautical miles at service speed and an endurance of 20 days. Brazil to start the construction of 11 new NPa500MB offshore patrol vessels (navyrecognition.com) The planned total cost for the eight NPa500MB OPVs is estimated at 2.8 billion reais (~476 million USD), while three other vessels will be specifically configured for mine countermeasures operations.

Perman Posted March 31 Author Report Share Posted March 31 (edited) Tanker plöjde in i kaj och tre brasilianska patrullbåtar: Quote Videos have emerged showing an out of control commercial oil tanker hitting a row of three Brazilian Navy patrol boats, as well as the pier, in the Port of Santos along the country’s southeastern coast last night. The Brazilian-flagged Olavo Bilac suffered an issue with its rudder while maneuvering between piers, according to multiple Brazilian media reports citing the Port Authority of Santos. The incident happened at around 11:20 PM local time on Wednesday. The Port of Santos is situated just to the southeast of the city of São Paulo. Quote As can be seen in the videos below, which offer views of the incident from what appears to be a closed circuit camera at the port and the ship’s deck, the nearly 817-foot-long (249-meter-long) Aframax class tanker first went careening into a pier after the loss of rudder control. It then struck a moored patrol boat, which was then pushed into two other patrol boats. Quote The three Brazilian Navy vessels involved in the incident have been identified as two Grajaú class patrol boats, the Guajará and the Guaporé, as well as the Macaé class patrol boat Maracanã. The Grajaú class is a 200-ton-displacement design armed with a 40mm Bofors cannon and two 20mm Oerlikon cannons, and that has been in service in Brazil since the 1990s. The Macaé class, which has the same armament as the Grajaú class, is a newer 500-ton-displacement patrol boat, with the first one being commissioned in 2009. Out Of Control Tanker Plows Into Docked Brazilian Navy Vessels (twz.com) Den största av patrullbåtarna som skadades Maracanã är bara drygt två år gammal. Fartygen bygger på franska CMN Vigilante 400 CL54 patrullfartygs designen. Byggnationen av de tre sista enheterna av fem stoppades i mitten av 2010-talet för att åter fortsätta i början av 2020-talet. Klassen är bestyckad med en BAE 40 mm Mk4 och två 20 mm Oerlikon. Väl tilltaget arbetsdäck akteröver för alternativ bestyckning eller utrustning. Med lite högre fart, Sea Giraffe 1/x radar på masten, radar eldledning ovanpå bryggan och SAAB Trackfire i ställer för 20 mm Oerlikon pjäserna så skulle jag kunna tänka mig dessa som patrullfartyg för den svenska marinen.

Perman Posted April 3 Author Report Share Posted April 3 (edited) Brasilien köper de två stora amfibiefartygen av br Albion-klass: Quote On April 2, 2025, during the LAAD Defence & Security 2025 exhibition held at Riocentro in Rio de Janeiro, the Brazilian Navy and the British Royal Navy signed a letter of intent for the future transfer of the HMS Albion and HMS Bulwark, meaning that all ships of the Albion-class landing platform dock fleet are now subject to negotiations for acquisition by the Brazilian Navy. The document outlines the basis for formal negotiations, including technical assessments and financial and logistical discussions, with the objective of incorporating both ships into Brazil’s naval fleet. Det verkar som om Brasilien gör en bra affär. HMS Bulwark genomgick en omfattande renovering och ombyggnad från 2020 till 2024 för 72 miljoner pund, men återgick trots detta inte till aktiv tjänst utan förblev i reserv. Fartygen säljs nu för 20 miljoner pund enligt engelsk press och kommer även att användas för nödhjälp vid naturkatastrofer: Quote Admiral Edgar Luiz Siqueira Barbosa, Director-General of Materiel for the Brazilian Navy, stated that Brazil has experienced multiple recent situations where naval support has been required in response to natural disasters. He cited the floods in São Sebastião (São Paulo) in 2023 and in the state of Rio Grande do Sul in 2024 as examples. According to Admiral Siqueira Barbosa, the acquisition of the two ships would enhance the Navy's capacity to support the civilian population in emergency situations. He also emphasized that Brazil has a history of acquiring British-built naval platforms and that the country has gained operational experience with them over time. No official financial figure was disclosed at the signing, but on January 26, 2025, British newspapers reported that the sale of the two vessels was under discussion for a total of £20 million (approximately R$145 million). On February 4, 2025, the Brazilian Navy confirmed the ongoing negotiations to the newspaper O Globo. UK sign agreement for transfer of all Albion-class landing platform dock vessels to Brazil (navyrecognition.com) Fartygen kommer troligen att ersätta det gamla amfibiefartyget av LSL typ NDCC Almirante Saboia (f d br Sir Bedivere). Min bedömning är att man kommer att behålla det franskbyggda amfibiefartyget av LPD typ Bahia (f d fr Siroco) som anskaffades 2015. List of active Brazilian Navy ships The Albion-class ships served as afloat command platforms for the British Navy's amphibious task force and to transport, deploy, and recover troops, vehicles, and equipment in support of amphibious operations.

HMS Bulwark genomgick en omfattande renoveringoch ombyggnad från 2020 till 2024 för 72 miljoner pund, men återgick trots detta inte till aktiv tjänst utan förblev i reserv. För ett år sedan sades det att HMS Albion och HMS Bulwark skulle behållas i tio år till! Från Wikipedia: Quote It was confirmed that Albion would be the first of the two vessels to be placed at extended readiness, for a cost of £2.5 million, as Bulwark had recently finished a major refit. Running costs while in extended readiness are estimated to be £300,000 per annum to keep the vessel available for reactivation at short notice. HMS Albion re-entered high readiness when HMS Bulwark was put into extended readiness. In 2014 Albion entered a regeneration refit and rejoined the active fleet in 2016. The running costs of one of the Albion-class vessels at high readiness ranged from £17.7 million to £38.6 million per annum from 2007 to 2011. As of late 2018 Albion was in active service while Bulwark was held at extended readiness. Vad gjorde dessa fartyg så dyra att hålla i aktiv tjänst? Är britterna dåliga på att bygga fartyg som är billliga att ha i aktiv tjänst mha reparationsbehov mm? Quote Link to comment Share on other sites More sharing options...
Perman Posted April 4 Author Report Share Posted April 4 (edited) Quote För ett år sedan sades det att HMS Albion och HMS Bulwark skulle behållas i tio år till! Det är tekniskt möjligt att göra detta men det verkar framför allt saknas personal. 9 hours ago, vikingman said: Vad gjorde dessa fartyg så dyra att hålla i aktiv tjänst? Är britterna dåliga på att bygga fartyg som är billliga att ha i aktiv tjänst mha reparationsbehov mm? Det är svår fråga att besvara men jag tror det beror på flera olika orsaker. Om vi tar type 23 fregatterna t ex så byggdes dessa för 18 års tjänst (utan en större MLU) med bl a tunnare bordläggning. M a o så borde klassen alltså ha utgått mellan 2008 och 2020. När man nu tvingas behålla vissa type 23 fregatter till in på 2030-talet pga. uteblivna ersättare så tenderar de påtvingade MLU arbetena att bli både väsentligt dyrare och ta mycket längre tid. Speciellt de som genomförts de senaste åren. Här verkar de största orsakerna alltså dels vara en felbedömning när man designade fartygen och dels att man inte beställde ersättare i tid. Ungefär likadant var det f ö med landsättningsfartyget med hkp HMS Ocean som byggdes för 20 års tjänst. Vad gäller Albion Och Bulwark så har navylookout en intressant artikel i Febr om dessa där man bl a pekar på bristen på personal att bemanna dem (som t ex marina ingenjörer) och på tajta budgetar: Quote In a move described by John Healy as “common sense”, the withdrawal of the two LPDs (Landing Platform Dock) is predominantly due to a lack of sailors and tight budgets. The reasons for this decision have subsequently been clouded by political spin and weak operational justifications. Axing the LPDs can be defined as a pragmatic but non-strategic choice forced on the RN by circumstances. Quote The LPDs pioneered diesel-electric propulsion in RN surface ships but were never mechanically entirely satisfactory. Over time, they have been improved and never suffered defects of the magnitude of the Type 45 destroyers. Lacking much of the automation found in newer warships, they have an engine room requirement of 60, which is very high by modern standards. Marine engineers are in especially short supply and this pinch point is likely the single biggest hurdle the RN could not overcome in the effort to return HMS Bulwark to service. Royal Navy och Royal Marines kommer nu att ha ett gap på 8-10 år med kraftigt reducerad amfibieförmåga innan MRSS fartygen med en optimistisk bedömning börjar levereras 2032. Detta kommer inte minst att ha stor påverkan på Storbritanniens roll i JEF och på möjligheterna att skicka förstärkning till Norge i händelse av en rysk attack mot Natos norra flank: Quote Britain’s most valued and effective contribution to NATO are its maritime forces. The weakening of amphibious capability in particular undermines the excellent JEF security construct for the Baltic Sea region that is largely underpinned by naval force. There is also the long-standing commitment to reinforce Norway in the event of a Russian attack on NATO’s Northern Flank. While UK amphibious resources were never vast, they were at least coherent. För övrigt så verkar det inte alls vara säkert att Brasilien väljer att aktivera bägge fartygen. HMS Albion som är i sämst skick kan komma att användas som reservdelsfartyg för systerfartyget. What will be the real consequences of axing the Royal Navy’s LPDs? /Per Edited April 4 by Perman 2 Quote Link to comment Share on other sites More sharing options...
