I wasn't sure if I should have added this article to the existing nuclear weapons news topic or create a new topic in "The Bar."
WASHINGTON (AP) — Defense Secretary Chuck Hagel has concluded that problems in the nation's nuclear forces are rooted in a lack of investment, inattention by high-level leaders and sagging morale, and is ordering top-to-bottom changes, vowing to invest billions of dollars to fix the management of the world's most deadly weapons, two senior defense officials told The Associated Press on Thursday.
RUSSIAN SUB TESTS MIRV
Russia’s recent flight test of a submarine-launched ballistic missile involved multiple warheads, according to U.S. officials familiar with intelligence reports of the test.
The Nov. 5 test of an SS-N-23 Skiff missile was carried out from a Delta IV nuclear missile submarine submerged in the Barents Sea.
State-controlled Russian media reported that the missile’s unspecified number of multiple warheads traveled some 3,100 miles across northern Russia to the Kura missile impact range on the Kamchatka Peninsula.
The SS-N-23 was declared in the 2011 New Strategic Arms Reduction Treaty (START) as having four warheads. However, more modern versions of the SS-N-23 have been reported in the Russian press as carrying between eight and 12 warheads. If confirmed, the additional warheads would violate the treaty.
The flight test highlights Russia’s continuing development of strategic missile capabilities, including systems with multiple independently targetable reentry vehicles, or MIRVs.
By contrast, the Obama administration is reducing its multiple warhead missiles. The last of 450 land-based Minuteman III missiles was downsized from three warheads to one in June.
Russia conducted a flight test of a new land-based multiple warhead missile, the SS-27 Mod 2, in April that some experts say may have violated the New START prohibition on adding warheads to existing missiles.
The Pentagon’s 2010 Nuclear Posture Review stated that all U.S. land-based intercontinental ballistic missiles will be “deMIRVed” from three warheads to one.
“This step will enhance the stability of the nuclear balance by reducing the incentives for either side to strike first,” the review stated.
U.S. Trident submarine-launched missiles, however, will continue to be armed with multiple warheads.
There are concerns, however, that Russia may be improving its new Bulava submarine-launched missiles with multiple maneuvering warheads — systems designed to defeat U.S. strategic missile defenses.
“There is a lot of talk in the Russian press about maneuvering warheads and 10 warhead packages for the Bulava,” said Mark Schneider, a former Pentagon strategic nuclear weapons specialist.
The Russian military enthusiast blog russianforces.org reported in August that the Makeyev Design Bureau, a nuclear missile center, is developing a maneuvering warhead for land- and sea-based missiles.
The Bulava was last tested in October and was equipped with six dummy warheads. It will be deployed on two new Borei-class missile submarines.
PARIS — France has launched studies for an airborne nuclear-tipped missile to replace the current weapon, with the focus on stealth and hypersonic technology on the next-generation atomic arms, Defense Minister Jean-Yves Le Drian said.
The Air Force flies the Dassault Mirage 2000N and Rafale F3 fighters armed with the air-sol moyenne portée-améliorée (ASMP-A) nuclear missile, respectively on the Gascogne and La Fayette squadrons. These are the airborne systems in addition to the four ballistic nuclear missile submarines.
“The studies for the successor to the ASMP-A missile, dubbed ASN4G, have already begun,” Le Drian told a high-level conference on the French nuclear deterrent on Nov. 20. ASN4G is understood to refer to air-sol nucléaire fourth-generation, an industry executive said.
The sensitivity of the deterrent was such that the conference organizer showed an extended video clip of a training mission that obscured an ASMP-A missile carried under the fuselage of a Rafale. A special edition of specialist magazine Air & Cosmos carried a cover picture of a weapon marked ASMP-A under a Rafale. The published pictures are understood to have been adapted by the Air Force to avoid giving too much detail. Air & Cosmos was not available for comment.
Copies of the magazine were distributed at the conference.
“The daring concepts, for example, based on stealth and hypersonic technologies, at the forefront of technological development, will be explored,” Le Drian said.
The projects are key to overcoming the enemy’s interdiction and also for the domestic industrial and technology base, he said.
“The choice of the future weapon system, comprising the ASN4G missile and a platform to be decided, is therefore a major issue for the services,” he said. The project is closely tied to the future format of the Air Force, he said.
Work began in the summer on the ASMP-A, intended to allow the air-breathing missile to defeat future air defense systems out to 2035, Le Drian said. The work consists of design and development studies for the mid-life upgrade, a source said.
Chief of the Air Staff Gen. Denis Mercier previously gave a glimpse of the technology studies on the future airborne weapon, which will call for a choice between stealth or speed.
A stealth study and one on hypersonic speed are underway for the successor to the ASMP-A, Mercier told the defense committee of the lower-house National Assembly in April. The hypersonic weapon might be capable of Mach 7 or 8, he said.
MBDA is prime contractor on the ASMP-A.
Mercier told the parliamentarians he preferred the hypersonic missile.
“It’s the second solution that I prefer,” he said. Mastery of the hypersonic is already a given factor, he said. The U.S., Russia, China, India are looking at the hypersonic technology as they consider a modernization of the airborne nuclear element, with experimental work conducted, he said.
On the future platform carrying the atomic weapon, a choice had to be made on the architecture and performance of the missile, he said. Two options are under study: a new generation fighter, and a bomber.
“The challenge is to select a system able to penetrate defense systems which will be deployed in 20 to 50 years,” he said. The work was also important for the industrial base, he said.
Anti-missile defense has made much progress against ballistic and cruise weapons, he said.
The work on the stealth or hypersonic missile technology will influence development of the future aircraft. For instance, if a hypersonic missile were capable of flying at Mach 7 and were 20 meters long, the aircraft would need to be a large plane, such an Airbus A400M, rather than a fighter such as the Rafale.
Armée de l'air française said:Au cœur d'une mission des forces aériennes stratégiques
Jeudi 20 novembre 2014, l’armée de l’air et le commissariat à l’énergie atomique et aux énergies alternatives ont organisé un colloque intitulé « 50 ans de dissuasion nucléaire : exigences et pertinence au 21ème siècle ».
Lors de ce colloque une vidéo fut projetée illustrant les différentes phases de la mission des Forces aériennes stratégiques (FAS).
