Sub project 'won't finish until 2054'

https://www.news.com.au/technology/innovation/military/controversial-submarine-project-wont-finish-until-2054/news-story/5d10878c7e6e02c4d7bbd2b9dc057938#.h4szi via @newscomauHQ

Dus de laatste nieuwe boot wordt afgeleverd in 2054
elke 2 jaar wordt een nieuwe boot afgeleverd.
eerste Collins klasse boot is van 1996
laatste Collins klasse boot is van 2003
eerste Collins klasse boot zal in 2030 uit de vaart worden gehaald

met deze gegevens kan men zeggen dat ;
- eerste boot zal uit de vaart gaan in 2030 en zal dan 34 jaar dienst gedaan hebben
- laatste boot zal uit de vaart gaan in 2042 en zal dan 39 jaar dienst gedaan hebben
- eigenlijke vervanging van 6 boten Colins klasse is in 2042.
- de uitbreiding met 6 boten zal dan nog 12 jaar duren

Wat is de opwerk tijd ? ... 1 jaar voor de bemanning ?

Dus dat betekend dan na 2030 Australië zeker niet kan beschikken over 6 onderzeeboten, maar eerder 5 boten in verband met opwerk tijd, opleidingen e.d. dit zal zeker doorgaan tot ca. 2044/45, dan pas weer beschikking over 6 boten.
Maar effectieve inzetbaarheid is natuurlijk lager door onderhoud, opleidingen e.d.
 
Maar met alle nu al ontstane problemen, vertragingen is het maar de vraag of de eerste te leveren boot wel in 2030 wordt afgeleverd ! Als de Collins klasse eerder uit de vaart worden gehaald dan dat de vervangers in dienst komen ontstaan er grote problemen.
Bijvoorbeeld als de levering pas in 2034 (of nog later) zal plaats vinden en de eerste Collins boot wel in 2030 uit dienst wordt gehaald dan kan het zo maar zijn dat Australië een tijd effectief 1 of geen onderzeeboten tot zijn beschikking heeft.
Ik voorzien grote problemen als de in dienst stelling nog verder in de tijd wordt doorgeschoven.

Hoe dan ook de bestaande Collins klasse zal een upgrade moeten krijgen.

Ik kan het daar mee eens zijn. Maar helaas heeft de politiek hierin het laatste woord. En de politiek kijkt anders aan in deze materie dan de gebruiker.

Nee niet meer zo irrationeel als voorheen, Defensie is veel meer geworden dan een onderhandelingsfiche.

We moeten echt god op de blote knieën danken als we ontsnappen aan Franse onderzeeërs, dat zou het ergste nieuws voor Nederland ooit zijn.

IAI Elta & Hensoldt Optronics announce collaboration on integrated communications and surveillance system for submarines



October 21, 2020- ELTA Systems, a subsidiary of Israel Aerospace Industries (IAI), and Hensoldt Optronics announce collaboration on an Integrated Communication and Surveillance (ICS) system for submarines. Targeted for Intelligence Surveillance and Reconnaissance (ISR) missions, the ICS is a fully integrated system combining HENSOLDT's Optical Surveillance Optronics Mast OMS150 with ELTA's SIGINT and SATCOM payloads.  During the past decade, there is an emerging trend in the operational world of submarines where the submarine is no longer a "stand-alone" platform involved in predefined missions, but rather an integrated part of a Naval Task Force. The demand is now for submarines to perform optical surveillance capability day and night and in all weather conditions, monitor radar and communication transmissions, and intelligence gathering. The resulting intelligence is sent through a secure tactical communication to a remote command.  These requirements have driven navies to procure more ISR sensors and high-reliability communication systems.  Typically, the sensors and communication systems would have to be installed on multiple masts, but ICS houses all the sensors within a single uniquely engineered mast to minimize the impact on the submarine's stealth signature.

IAI VP and CEO of ELTA Yoav Tourgeman said "As part of ELTA's new strategy, we are ramping up our collaborations with global business entities by leveraging our advanced technological experience and know-how accumulated over decades of defense operations. This collaboration will bring value to our customers by offering a unique, cost-effective, compact and high-utility solution".

Director Sales Hensoldt Optronics Maritime, Harald Hansen states, "Providing a single integrated mast solution will truly satisfy our customers who are searching to enhance their submarines' capabilities while being sensitive to the limited amount of space available and retaining a high degree of stealthiness."

The ICS performs optical surveillance, radar warning and detection and monitoring of GPS, voice and other communicating transmissions between ships, land or airborne platforms. The data gathered in real time can provide the submarine's crew vital information regarding the enemy's exact location and current situation. It is equipped with a SATCOM and Laser system for secure communications.

The ICS will be displayed virtually at Euronaval 2020 exhibition at both Hensoldt and IAI booths.

Taiwan to launch next year upgrade program of its Chien Lung-class submarines

According to news published by the "Taiwan News" website on September 30, 2020, the Taiwanese Ministry of National Defense (MND) has announced that the program to upgrade the Taiwanese Navy Chien Lung-class submarines will be launched next year and completed by 2024.

Citing the "Taiwan News" website the Tawainese Ministry of Defense that the National Chung-Shan Institute of Science & Technology (NCSIST) and the Dutch company RH Marine will be in charge to modernize the two Chien Lung-class submarines, SS-793 Hai Lung (Sea Dragon) and SS-794 Hai Hu (Sea Tiger). the two submarines entered in service in 1987 and 1988 respectively.

The aim of this upgrade is to extend the operational capabilities of the two submarines into late 2030, according to the Taiwanese Ministry of Defense.

The Chien Lung class of submarine, also known as the Hai Lung (Sea Dragon) class, was manufactured in the Netherlands for Taiwan. They are a modified version of the Dutch Navy's Zwaardvis class which itself is based on the US Barbel class. It has a crew of 67 sailors including 8 officers.

The Chien Lung class submarine has a length of 66.9 meters with an 8.4-meter-wide beam and can reach a speed of up to 20 knots when submerged. Their weapons systems are capable of launching up to 28 torpedoes from their six 533mm torpedo tubes. It can fire the AEG SUT 264 torpedo (dual-purpose - wire-guided, active/passive homing) produced by the German company Atlas Elektronik and the UGM-84 Harpoon anti-ship missile fitted with a solid-fuel rocket booster and encapsulated in a container to enable submerged launch through a torpedo tube.

The Chien Lung class submarines are fitted with diesel-electric propulsion systems that include three Bronswerk/Stork-Werkspoor RUB 215x12 diesel engine developing 4,500 hp.

Russia's P-750B Small Attack Submarine Design by Malakhit Design Bureau

The United Shipbuilding Corporation displayed at Army-2020 forum a scale model of the new Serval-class P-750B submarine, the Independent Military Review writes

It is distinguished by more details than the submarine presented at the navy show in St. Petersburg last year. A part of the skin was withdrawn for the visitors to see the constructive specifics of the submarine and the changes introduced by Malakhit Design Bureau from July to December 2019 when the final concept was specified.

Serval P-750B has a displacement of 1400 tons and is equipped with an air-independent (anaerobic) power plant. It is a prospective submarine with numerous advanced solutions and technologies. The innovative approach of Malakhit manifested itself in the conceptual project completed in early 2020. 3D methods were used to calculate hydro dynamic characteristics and properly place equipment at an early state of the design.

Now it is necessary to specify the main technical solutions. Pipelines and cables are to be laid. 3D modeling will simplify the job. Construction materials, including metal alloys and composites are to be specified for the hull and the interior.

Serval is distinguished from all Russian non-nuclear subs by a gas turbine which replaced the classical diesel generator and a battery to power the electric engine. The idea is not new, but so far nobody succeeded to implement it although gas turbines are broadly used on surface warships.

The advantages of a gas turbine include its compact size, a high specific power and excellent acceleration rate. Modern gas turbines have a high resource. They are expensive in production, but can decrease life cycle costs.

Malakhit paid specific attention to safe operation. The power plant uses exhaust gasses enriched with oxygen instead of the atmospheric air. They are to be cooled and purified by the so-called Dewar vessels. P-750B power plant is rated as air-independent.

The submarine has a propulsion electric motor of 2500 HP (three-day underwater navigation with the battery) and a pair of diesel gas turbines of 450 KW each. They provide a speed of 10-12 knots.

The turbines operate in two regimes. The first one is for surfaced and the second one is for submerged position. The power plant consumes atmospheric air in the former case and liquid oxygen from cryogenic storage of Dewar vessels in the latter case. They freeze the exhaust gasses and there is no need to discharge them into the atmosphere. P-750B with a displacement of 1400 tons can sail 1200 miles underwater at an economical speed of four knots and maximum depth of 300 meters.

S. Korea Plans to Build Ballistic Missile Submarines

Defense Ministry Plans to Build Enhanced Ballistic Missile Submarines

The Defense Ministry said Monday it plans to roll out enhanced submarines in the next five years that will be capable of carrying more ballistic missiles, as part of a long-term initiative to beef up South Korea's military capabilities.

It also plans to develop its own interceptor system like Israel's Iron Dome to defend the country's core infrastructure in the capital area against North Korea's long-range artillery threats.

"We have in mind 3,600- and 4,000-ton submarines for development, much more advanced than the ones in operation now," a senior ministry official said, referring to the 3,000-ton Dosan Ahn Changho, the first locally made attack submarines.

The official said the ministry was positive that the new submarines would be capable of carrying more ballistic missiles than the existing Dosan submarines, which have six launching tubes.

The advanced sub and interception system plans are part of the government's defense blueprint for 2021-2025, unveiled Monday, which calls for spending 300.7 trillion won ($253 billion), a 6.1 percent on-year hike on average over the next five years.

As for the submarine development program, the ministry left open the possibility that the new subs could be powered by nuclear energy instead of diesel fuel.

"We will discuss that when the right time comes," the senior official said when asked directly.

Nuclear-powered submarines are considered more powerful than diesel submarines because they can stay under water unnoticed much longer. They can also travel much faster. Only six countries including the US and Russia are known to possess them.

South Korea initially pushed to build its first nuclear submarine in 2003, amid rising military tensions prompted by North Korea's withdrawal in the same year from the non-proliferation treaty that prevents the spread of nuclear weapons technology.

But Korea had to abort the mission in 2010 as the International Atomic Energy Agency, backed by the US and countries opposing Seoul's plan, took issue with it, out of fear it could spark an arms race in the region.

To develop nuclear-powered military assets, Seoul would also have to revise a nuclear pact with Washington, under which Seoul is committed to using only a limited level of enriched uranium for nonmilitary purposes only.

The ministry also said it would develop a variety of missiles that could go with its first locally developed fighter jets, the KF-X, which will be commissioned next year.

The KF-X project is the largest undertaking ever by the South Korean military, with some $15 billion earmarked for it and with the end product set to be delivered to the Air Force in 2026.
