Possibilité d'un tir doublé comme pour le dernier le 2 février 2015 (a moins que j'en ai loupé un) ? 155 succès d'affilé depuis 1989, cela fait 4 à 5 tirs par ans - le 130e tir ayant lieu en mars 2011-:

http://www.lockheedmartin.com/us/news/press-releases/2015/february/ssc-space-trident.html

Les débuts ont tout de même était difficiles avec 3 échecs sur 19 lors des lancements à terre depuis Cap Canaveral et les 1et et 3e tir depuis un SNLE qui on était un flop en 89 mais à partir du 4e, ''c'est la routine'' ;

Bizarre, je viens de remarqué qu'il n'y a pas D5X-16 dans la liste des tirs à terre ? :

Members of Congress, USSTRATCOM commander observe missile launch from ballistic missile submarine

U.S. Strategic Command Public Affairs

11/9/2015

OFFUTT AIR FORCE BASE, Neb. – Members of Congress and the U.S. Strategic Command (USSTRATCOM) commander were aboard the USS Kentucky when the U.S. Navy’s Strategic Systems Programs (SSP) conducted a successful test flight of a Trident II D5 Missile, Nov. 7, 2015, to obtain valid reliability, accuracy and performance factors for use by the Joint Chiefs of Staff and USSTRATCOM.

The unarmed test missile was launched as part of a Demonstration and Shakedown Operations (DASO) from the USS Kentucky, an Ohio Class ballistic missile submarine (SSBN), in the Pacific Test Range off the coast of Southern California. The primary objective of a DASO is to demonstrate the readiness of a SSBN’s crew and weapon system. This launch marked the 156th successful test flight of the Trident II (D5) missile conducted by SSP since 1989.

“A credible, effective nuclear deterrent is essential to our national security and the security of U.S. allies and friends,” said Adm. Cecil D. Haney, USSTRATCOM commander, who monitored the test from the USS Kentucky (SSBN 737).

Admiral Haney stated that “strategic weapons tests demonstrate the readiness of our nation’s nuclear triad and serve to assure our allies and deter our potential adversaries.” He went on to say that exercises, weapons tests and operations are an important part of validating that our deterrence forces are capable 24/7.

Also witnessing the test was a congressional delegation including Sen. Joe Donnelly (Indiana), Rep. Stephen Womack (Arkansas), Rep. Pete Visclosky (Indiana), Rep. Jackie Walorski (Indiana), Rep. Larry Bucshon (Indiana) and professional staff members from senate and house subcommittees.

“I’m thrilled that some of our congressional members were able to take the time to witness this test and to see firsthand the professional and dedicated submariners conducting the strategic deterrence mission, as well as the team of professionals supporting the test” said Haney.

Haney encouraged the observers to share their experience with their colleagues and others as he discussed the importance of strategic deterrence for our nation today, and for tomorrow’s future.

The triad, the U.S. strategic nuclear forces of ballistic missile submarines, intercontinental ballistic missiles, bombers and the tankers that refuel them, along with intelligence, sensing capabilities, national nuclear command, control and communications, altogether comprise the primary deterrent of nuclear attacks against the U.S., our allies, and partners.

The U.S. Navy supports USSTRATCOM's strategic deterrence missions by operating and maintaining Ohio-class ballistic missile submarines, the most survivable leg of the triad, to deter regional and strategic threats. The weapon system is a critical element that underpins U.S. national security.

“It is safe, secure, effective and ready today, but the platform is aging and in need of replacement. I look forward to continued progress on the Ohio Replacement Program to ensure the Nation has this capability well into the future to continue providing security for America and our allies,” Haney said.

"Ensuring our nation's strategic forces have the resources they need, are trained to the highest standards, and are ready to perform their critical mission remains one of the most important priorities I hold as an elected official," Walorski said. "I want to thank the brave men and women who serve in our submarine and strategic forces communities, your quiet sacrifices, often absent from any headlines, protect the freedoms that all Americans enjoy. We are forever grateful for your service."

U.S. Navy’s SSP conducted another successful test flight – the 157th – of a Trident II D5 Missile, Nov. 9. The unarmed test missile was also launched as part of a DASO from the USS Kentucky in the Pacific Test Range off the coast of Southern California. Haney and the congressional members, however, were not on board.

One of nine DoD unified combatant commands, USSTRATCOM has global strategic missions, assigned through the Unified Command Plan, which include strategic deterrence; space operations; cyberspace operations; joint electronic warfare; global strike; missile defense; intelligence, surveillance and reconnaissance; combating weapons of mass destruction; and analysis and targeting.

Un 2ème tir de Trident D5 a eu lieu le 9 Novembre, qui est également le 157ème essai :

Navy launches second test missile off Southern California coast

The U.S. Navy said it launched a second -- and final -- missile in a planned exercise Monday afternoon from a submarine off the Southern California coast.

The second test launch of the Trident II (D5) missile from a ballistic submarine in the Pacific Ocean took place Monday afternoon, the Navy said. The blast-off took place to far less fanfare than Saturday night’s launch, which provoked residents from San Francisco to Mexico to take to social media, posting photos of an eerie-looking bluish-green plume smeared above the Pacific.

Speculations were wide-ranging, including rumors of an otherworldly alien UFO visit. In fact, the streak was generated from the Trident missile’s rocket motor.

The Navy later confirmed a ballistic submarine launched an unarmed Trident II (D5) missile in a test flight, but would not define the window of time available for conducting additional launches, nor would it disclose where the exercise was actually taking place.

“It’s important that we test these missiles for our national security,” said John M. Daniels, spokesman for the secretive Strategic Systems Programs office, which oversees the Navy’s nuclear-tipped missile arsenal. “We don’t announce future launches, but this is it for any time soon.”

The Kentucky, the ballistic submarine, conducted the two launches as part of a demonstration and shakedown operation, or DASO, process that certifies the readiness of a submarine’s crew and strategic weapons before returning to operational availability.

It occurs after a submarine has its mid-life nuclear refueling, which involves replacing the expended nuclear fuel in the submarine’s reactor with new fuel. The Kentucky entered Puget Sound Naval Shipyard in Bremerton, Wash., in February 2012 for an overhaul that ended in April.

The Navy is considering posting additional photos -- and possibly video -- of the missile launches after the current exercises are completed, Daniels said, but it has yet to decide.

The Navy’s fleet of 14 ballistic submarines can each carry 24 Trident missiles, each tipped with 14 independently targetable thermonuclear warheads. 

The Navy annually tests the Tridents, on the West Coast and on the East Coast, near Florida.

The $31 million missile, built by Lockheed Martin Corp. in Sunnyvale, Calif., has had more than 150 successful launches since its first test in 1989. It is capable of hitting a target 4,000 nautical miles away.

The test on Saturday featured the launch of a missile outfitted with a dummy warhead toward the Kwajalein Atoll, a missile test site that’s part of the Marshall Islands in the western Pacific. 

While the risk of nuclear confrontation between the United States and Russia declined after the 1991 fall of the Soviet Union, it has never gone away.

The U.S. military’s nuclear weapons strategy rests on a triad of delivery systems — bombers, submarines and land-based missiles — developed early in the Cold War to deliver warheads anywhere in the world.

The Pentagon recently embarked on a $355-billion program for modernizing each aging leg of the U.S. nuclear triad over the next decade.

The submarine missile test came late Saturday after Defense Secretary Ashton Carter addressed a defense forum at the Ronald Reagan Presidential Library in Simi Valley about the U.S. “adapting our operational posture and contingency plans” to deter Russia’s “aggression.”

“We do not seek a cold, let alone a hot, war with Russia,” he said to the forum. “We do not seek to make Russia an enemy. But make no mistake; the United States will defend our interests, our allies, the principled international order, and the positive future it affords us all.”

Ces lancements ont bien entendu engendré de nombreux signalements d'OVNI en Californie...

Plus sérieusement, j'ai trouvé sur la toile une analyse visuelle de ce lancement, montrant la signature de chaque phase de vol.

Un incident ayant endommagé un ICBM en 2014 vient d'être confirmé par l'US STRATCOM.

Les détails de l'incident sont toujours classifiés : il semble que durant un diagnostic sur missile le 16 Mai 2014, le personnel n'a pas suivi toutes les procédures, et a rendu le missile non opérationnel (:excl: sic!)

Les équipes impliqués ont "seulement" écopé d'une suspension de certification nucléaire de 1 an.

En résumé, ça défrise.
En comptant toutes les armes (dont les SLBM, SAM, torpilles, ASROC, et charges anti soums à tête nucléaires, et les bombes sur porte avion), il y a eu jusqu'à 6100 têtes nucléaires emportées par l'US Navy. Avec des pointes à 4500 dans l'Atlantique, et 500 en méditerranée.

Encore un Trident. Un tir tout les trimestres ?

Non, c'est un Minuteman III de l'Air Force Global Strike Command depuis la base Vandenberg, mais je ne vais pas ouvrir un autre fil spécifique. La portée est de 4 200 miles, soit 6 759 km.

MINOT TESTS MINUTEMAN III MISSILE WITH LAUNCH FROM VANDENBERG

Citation

Air Force Global Strike Command Public Affairs / Published February 21, 2016

VANDENBERG AIR FORCE BASE, Calif. --

A team of Air Force Global Strike Command Airmen from the 91st Missile Wing at Minot Air Force Base, North Dakota, and the 625th Strategic Operations Squadron at Offutt AFB, Nebraska, aboard the Airborne Launch Control System, launched an unarmed Minuteman III intercontinental ballistic missile equipped with a test reentry vehicle at 11:34 p.m. Pacific Standard Time, Feb. 20, from Vandenberg AFB, California.

The ICBM's reentry vehicle, which contained a telemetry package used for operational testing, traveled approximately 4,200 miles to the Kwajalein Atoll in the Marshall Islands. Test launches verify the accuracy and reliability of the ICBM weapon system, providing valuable data to ensure a continued safe, secure and effective nuclear deterrent. All MMIII test launches are supported by a team from the 576th Flight Test Squadron at Vandenberg AFB.

"The flight test program demonstrates one part of the operational capability if the ICBM weapon system,” said Col. Craig Ramsey, 576th FLTS commander. “When coupled with the other facets of our test program, we get a complete picture of the weapon system's reliability. But perhaps most importantly, this visible message of national security serves to assure our partners and dissuade potential aggressors."

Minot AFB is one of three missile bases with crew members standing alert 24 hours a day, year-round, overseeing the nation’s ICBM alert forces.

"It has been an amazing experience for the operations and maintenance members of Team Minot to partner with the professionals from the 576th FLTS, 30th SW and 625th STOS,” said Maj. Keith Schneider, 91st MW Task Force Director of Operations. “Everyone involved has worked hard and dedicated themselves to the mission.”

The ICBM community, including the Department of Defense, the Department of Energy, and U.S. Strategic Command uses data collected from test launches for continuing force development evaluation. The ICBM test launch program demonstrates the operational credibility of the Minuteman III and ensures the United States’ ability to maintain a strong, credible nuclear deterrent as a key element of U.S. national security and the security of U.S. allies and partners.

Tir d'essai de 3 missiles Trident II D5 avec succès sur une distance de 9 500 km environ, c'est le 158ème, 159ème et 160ème vols de Trident II D5.

Navy test fires Trident missiles

Citation

A U.S.Navy submarine has test fired three Trident ICBMs.

By Richard Tomkins   |   March 17, 2016 at 1:51 PM

WASHINGTON, March 17 (UPI) -- Three Trident II D5 missiles were launched by a U.S. Navy ballistic missile submarine to validate their accuracy and performance.

The unarmed missiles were fired over a three-day period by an Ohio-class vessel at sea, flew over the sea and landed in the sea, the Navy said, completing a Follow-on Commander's Evaluation Test.

"A credible, effective nuclear deterrent is essential to our national security and the security of U.S. allies and friends," the Navy said. "Strategic weapons tests, exercises and operations such as FCET-52 demonstrate the readiness of the submarine launched Trident II missile. As the most survivable leg of our strategic deterrent Triad, it provides the national command authority with assured second-strike capability."

Trident is a key part of the U.S. strategic deterrent. It is a submarine-launched ballistic missile with multiple, independently targetable re-entry vehicles with thermonuclear warheads.

The test firings were the 158th, 159th, and 160th successful test flights of the Trident II D5 missile.

Les USA sont en train de déployer un nouveau modèle de tête nucléaire, qui est beaucoup plus efficace pour les frappes anti-forces:

http://thebulletin.org/how-us-nuclear-force-modernization-undermining-strategic-stability-burst-height-compensating-super10578

Ca pourrait leur permettre de détruire les forces nucléaires terrestres russes avec peu de missiles, et donc de pouvoir frapper d'autres objectifs en plus. Du coup ça met Moscou dans une situation inconfortable.

Un détonateur réglable ? Cela n'existait pas auparavant sur les bombes H ?

Tu n'as pas lu?

En fait c'est pas qu'il soit réglable.

Avant on fixé avant le tir l'altitude d'explosion. Et toutes la tete explosé a l'altitude programmé point. Sauf que les tete sont pas précise et donc certaine tombe trop long d'autre trop court.

Les têtes tombent en oblique.

Celle qui tombe trop court et qui est programmée pour péter a 100m d'altitude, si elle avait pété a 0m ca se trouve elle aurait pété pile sur la cible. Certes au raz du sol mais pile quand meme.

Celle qui tombe trop long et qui pete a 100m d'altitude... si elle avait pété a 150m d'altitude, ca se trouve elle aurait pété pile au dessus de la cible.

Les US on défini une bulle au dessus de la cible, qui forme un volume - une sorte de tulipe a l'envers - dans le lequel la bombe doit pété pour avoir l'effet voulu sur la cible souterraine.

Et au lieu de faire péter leur bombe a altitude programmé ... il libere la variable altitude et lui demande juste de péter dans cette bulle que ce soit a 0 ou a 150m on s'en fout.

Résultat pour la meme incertitude de positionnement plus de bombe explose dans la bulle ... et donc moins de bombe son nécessaire pour détruire le meme nombre de cible souterraine. Selon les calcul US le systeme aurait une réussite trois fois supérieur avec cette fusée "paramétrique" qui prend en compte l'erreur de position, l'altitude, et l'enveloppe précise ou il est idéal de péter, pour péter ... plutot que betement une altitude préprogrammé auparavant.

Évidement pour une bombe atomique un déclencheur un tout petit peu intelligent  c'est pas si surprenant que ça ... mais force est de constaté qu'auparavant probablement pour de simple raison de fiabilité on s'était contenté d'un déclenchement altimétrique.
