FRANCE MEETS WITH SOME DIFFICULTIES IN DESIGN OF ITS NEW AIRCRAFT CARRIER

France plans to build a new aircraft carrier, but already meets some difficulties in its design.

France has plans to build its second aircraft carrier, which will become a part of the future French President’s program, the French L’Opinion newspaper reported. According to the newspaper, the new vessel’s preliminary design, which will cost about €100 million per year, can be started during the next five years. Some experts believe that the aircraft carrier’s construction will be begun in 2020, and the vessel will be totally ready by 2035. However, the exact time limits are still unclear.

As L’Opinion noted the new ship will replace the Charles de Gaulle aircraft carrier. At the same time, it is possible that at the moment of entering into service of the new vessel, there will be two nuclear aircraft carriers in the French fleet. It is highly likely that the new ship will be built in Saint-Nazaire, but not in Brest, where its predecessor was constructed.

However, it is still necessary to solve a number of serious technical and operational issues about nuclear reactors and catapults.

The Charles de Gaulle is equipped with two K15 nuclear reactors – the same type of reactors is used for the Triomphant nuclear missile submarines and the new Barracuda multipurpose nuclear submarines. The K15’s power is 150 MW that is barely enough for the aircraft carrier. Meanwhile, US nuclear aircraft carriers such as Nimitz have two nuclear reactors, the power of each of which is 550 MW (3.7 times more powerful than Charles de Gaulle’s reactors).

Designers of the future French aircraft carrier should decide whether they will equip the ship with three K15 nuclear reactors or develop a new one for it. Three K15 reactors would take up more space that means that the ship would be bigger and heavier. Development of a new reactor would require a lot of money. As the newspaper assumed, most likely the К15+ reactor will be created, but its improvements will very quickly show their limits. At the same time, it will be necessary to think of new reactors for future third-generation ballistic missile submarines, which will come to replace the Triomphant.

One of the other pressing problems is issue of preservation of the industry competencies, in particular the Areva TA and DCNS companies or the Commission for Atomic Energy. A variant of creating an aircraft carrier with a non-nuclear power-plant unit, as is the case with two promising aircraft carriers of the British Navy, is also considered, but it has few supporters, both among the French Navy and in the industry.

In addition, there is also an issue of a catapult’s choice. France does not produce such equipment. Catapults for the Charles de Gaulle were purchased in the US and the same will also be made for the next aircraft carrier. However, the US is moving away from the steam catapult technology to the new generation of electromagnetic catapults. In this way, the purchase price, as well as the electrical power, required for its operation, are unknown.

In these conditions it is difficult to estimate the cost of the future aircraft carrier, but, as the newspaper noted, it certainly will be €4-6 billion.

Why States Still Use Barrel Bombs

Smoke ascends after a Syrian military helicopter allegedly dropped a barrel bomb over the city of Daraya on Jan. 31.(FADI DIRANI/AFP/Getty Images) Summary Barrel bombs are not especially effective weapons. They are often poorly constructed; they fail to detonate more often than other devices constructed for a similar purpose; and their lack of precision means they can have a disproportionate effect on civilian populations. However, combatants continue to use barrel bombs in conflicts, including in recent and ongoing conflicts in Africa and the Middle East, and they are ideally suited to the requirements of resource-poor states. Analysis Barrel bombs are improvised devices that contain explosive filling and shrapnel packed into a container, often in a cylindrical shape such as a barrel. The devices continue to be dropped on towns all over Syria . Indeed, there have been several documented cases of their use in Iraq over the past months, and residents of the city of Mosul, which was re

Russia Looks East for New Oil Markets

Click to Enlarge In the final years of the Soviet Union, Soviet leader Mikhail Gorbachev began orienting his foreign policy toward Asia in response to a rising Japan. Putin has also piloted a much-touted pivot to Asia, coinciding with renewed U.S. interest in the area. A good expression of intent was Russia's hosting of the Asia-Pacific Economic Cooperation summit in 2012 in Vladivostok, near Russia's borders with China and North Korea. Although its efforts in Asia have been limited by more direct interests in Russia's periphery and in Europe, Moscow recently has been able to look more to the east. Part of this renewed interest involves finding new export markets for Russian hydrocarbons. Russia's economy relies on energy exports, particularly crude oil and natural gas exported via pipeline to the West. However, Western Europe is diversifying its energy sources as new supplies come online out of a desire to reduce its dependence on Russian energy supplies . This has

LONDON POLICE INDIRECTLY ENCOURAGE CRIMINALS TO ATTACK RUSSIAN DIPLOMATIC PROPERTY

ILLUSTRATIVE IMAGE A few days ago an unknown perpetrator trespassed on the territory of the Russian Trade Delegation in London, causing damage to the property and the vehicles belonging to the trade delegation , Russian Foreign Ministry Spokeswoman Maria Zakharova said during the September 12 press briefing. The diplomat revealed the response by the London police was discouraging. Police told that the case does not have any prospects and is likely to be closed. This was made despite the fact that the British law enforcement was provided with video surveillance tapes and detailed information shedding light on the incident. By this byehavior, British law inforcements indirectly encourage criminals to continue attacks on Russian diplomatic property in the UK. Zakharova’s statement on “Trespassing on the Russian Trade Mission premises in London” ( source ): During our briefings, we have repeatedly discussed compliance with the Vienna Convention on Diplomatic Relations, specif
