Le 5è sous-marin construit en Allemagne pour Israël se dirige vers Haïfa


18 décembre 2015. Portail des Sous-Marins

 

Le 5è sous-marin israélien de la classe Dolphin et le 2è équipé d’un propulsion anaérobie effectue le voyage de 3.000 nautiques en direction de son port-base, Haïfa, depuis le chantier naval allemand où il a été construit.

L’INS Rahav transporte quelques 50 maris ainsi que « le minimum d’armement nécessaire à sa protection, » avant son arrivée en Israël le mois prochain. Après son arrivée, les systèmes israéliens seront installés à bord.

« Nous espérons que le sous-marin sera complètement opérationnel d’ici quelques mois, » indique un responsable.

Les sous-marins anaérobies peuvent rester en plongée plus longtemps. Avoir 2 sous-marins de ce type signifie que la marine israélienne « a doublé ses capacités sous-marines, » explique l’officier.

Le sous-marin fera un arrêt sur le site où le sous-marin INS Dakar a coulé en 1968, pour effectuer une cérémonie commémorative. Il poursuivra ensuite son chemin vers Haïfa.

Les nouveaux sous-marins seront installés dans un bassin spécialisé construit dans la base navale de Haïfa. Les sous-marins seront gardés séparément, discrètement et d’une manière adaptée. Le bassin [1] est très flexible et permet l’appareillage des sous-marins 24 heures sur 24.

« Les sous-marins apportent un niveau de renseignement qu’Israël ne peut obtenir par d’autres moyens, » explique le Lt.-Cmdr. Y., un ancien commandant de sous-marin.

« Les drones peuvent être abattus, » souligne-t-il, « alors qu’un sous-marin peut rester pendant des semaines au large des territoires ennemis, sans que personne ne le sache. »

Submarines: Another Dolphin For Israel

 

January 13, 2015: Strategy Page

 

In September 2014 Israel received the fourth of six Dolphin class submarines from Germany. This the first of three new Dolphins that have a fuel cell based AIP (Air Independent Propulsion) system which enables them to stay under water for over a week at a time. The Dolphins in general are also very quiet, and very difficult to hunt down and destroy. The first three Dolphins didn't have the AIP system.

 

Germany continues to build Dolphin class boats for Israel, with the next one due to arrive in 2015 and the last one in 2019. The first three arrived in 1998-2000. The second three Dolphins cost about $650 million each, with Germany picking up a third of the cost on two of them. The first two Dolphins were paid for by Germany, as was most of the cost of the third one. This is more of German reparations for World War II atrocities against Jews.

 

The three older boats have since been upgraded to include larger fuel capacity, converting more torpedo tubes to the larger 650mm size, and installing new electronics. The fuel and torpedo tube mods appear to have something to do with stationing the subs off the coast of Iran. Larger torpedo tubes allow the subs to carry longer range missiles. The larger fuel capacity makes it easier to move Dolphins from the Mediterranean to the Indian Ocean. Although Israel has a naval base on the Red Sea, Egypt, until 2012, did not allowed Israeli subs to use the Suez Canal. So the Dolphins were modified to go around Africa, if they had to.

 

As built the Dolphins could stay at sea for about 40 days (moving at about 14 kilometers an hour, on the surface, for up to 8,000 kilometers). Larger fuel capacity extended range to over 10,000 kilometers and endurance to about 50 days. The 1,625 ton Dolphins can carry 16 torpedoes or missiles and have ten forward torpedo tubes (four of them the larger 650mm/26 inch size). The Dolphins are considered the most modern non-nuclear subs in the world. The first three cost $320 million each. All have a crew of 35 and can dive to a depth of more than 200 meters (660 feet). The Dolphin design is based on the German 209 class subs but has been so heavily modified that it is considered a different class and only Israel has them.

 

In early 2014 Israel revealed that in 2013 its submarines spent 58 percent of their time at sea on combat missions while the rest of the time was spent for training. Israel currently has four Dolphin class subs in service. The Israelis also admitted that their subs sometimes go far (to Iran and the Red Sea) from their bases on missions. Give that Israel is not at war with anyone with a navy, these missions are probably related to collecting information on the ships and ports of potential enemies. That would include Syria, Lebanon, Iran, Sudan and so on. The navy revealed that the subs undertook 54 “special operations” in 2013 and that was a big increase from previous years.

 

No details were given on what the special operations were but based on what kind of surveillance operations Israel has conducted in the past and what U.S. subs did in that area during the Cold War. The Israeli subs have probably been using their passive (listen only) sonar to collect information about ports and warships as well as deploying and retrieving larger electronic sensors placed underwater near where enemy ships operate. Israel may also be tapping underwater communications cables. For some of these operations the Israelis would use divers carried on the subs as passengers. Israel has a small force of naval special operations troops similar to the American SEALS and the British SBS.

 

All of the Israeli subs are built in Germany, where the local media periodically pretends to be appalled at what the Israelis actually do with these subs. Thus back in 2012 revelations in German media that the Dolphin class boats were equipped in Germany with a special hydraulic ejection (from torpedo tubes) systems for launching missiles with nuclear warheads caused a stir. This was actually misleading, as well as being old news. The Dolphin class subs have long had the ability to launch Harpoon anti-ship missiles and longer range cruise missiles from the torpedo tubes. It makes no difference if the warhead has high-explosives or a nuclear bomb in it. For over a decade Israel and Germany played down this capability. For example shortly after September 11, 2001 Israel denied that it had submarines capable of firing cruise missiles equipped with nuclear warheads. But the U.S. navy had reported spotting such missiles being tested by an Israeli sub in the Indian Ocean before 2001.

 

In 2000 it was widely reported that Dolphin class subs were being equipped with nuclear weapons. The 135 kilometer range Harpoon missiles were alleged to have been modified to carry a nuclear warhead and Israel. It was also asserted that Israel was developing a submarine launched 350 kilometer range cruise missile. Both of these weapons were launched from the subs torpedo tubes. Since then Israel has developed a new cruise missile, with a range of 1,500 kilometers and carrying a 200 kiloton nuclear warhead. These nuclear equipped subs were to provide an extra degree of security as all other Israeli nuclear weapons were in land bases and, in theory, could be wiped out by a surprise missile attack. A nuclear missile equipped submarine at sea would be much more difficult to find.

La marine israélienne va construire une base de sous-marins à Haïfa

3 juin 2013. Par Rédacteur en chef. PORTAIL DES SOUS-MARINS

 

Les préparatifs pour la réception par la marine israélienne de ses nouveaux sous-marins Dolphin, s’accélèrent : Elbit Systems a remporté l’appel d’offres lancé pour la construction de ’Polygon’ — le nom donné à la nouvelle base de sous-marins dans le port de Haïfa.

 

La construction de ‘Polygon’ est un énorme projet, rendu nécessaire par l’avancée de la construction des sous-marins dans les chantiers navals allemands. Israël a acheté 3 nouveaux sous-marins Dolphin, qui vont s’ajouter aux 3 qu’elle possède déjà. Selon la presse étrangère, les sous-marins peuvent embarquer des missiles à têtes nucléaires.

 

Les 2 premiers sous-marins devraient arriver en Israël dans les 2 prochaines années. Des équipes de la marine israélienne ont commencé le processus de réception en Allemagne.

 

La construction de ‘Polygon’ devrait se dérouler en plusieurs étapes.
