@DundF,
Vanguard und Triomphant sind zeitgleich entwickelt worden, allerdings haben die Franzosen den Zulauf ihrer SSBNs aus finanziellen Gründen zeitlich extrem gestreckt. Ursprünglich sollten alle vier längst ID sein wie die Vanguards.
Die Typhoons waren ursprünglich nur dafür gedacht, den relativ kurzen Weg bis zur Arktis zu fahren und unter dem Eis zu patrouillieren. Man war der irrigen Ansicht, dass man hier, quasi vor der Haustür, für ausreichenden Schutz sorgen konnte und baute daher möglichst große Boote. Die Delta IV wurde entwickelt, um einen technischen Fehlschlag mit den Typhoons abzufangen, ähnlich dem gleichzeitigen Bau der atombetriebenen Kirovs und der konventionellen und kleineren Slavas.
Z. Zt. finden ja großangelegte Übungen der strategischen Streitkräfte Russlands statt. Angeblich gab es dabei Fehlstarts von SS-N-23 Skiff/Delta IV.
Laut globalsecurity.org studieren die Amis eine neue IRBM, die von Ubooten aus abgefeuert werden soll:

"On 25 August 2003 the Department of the Navy, Strategic Systems Programs [SSP] issued a Request for Information (RFI) to determine the latest plans and programs including technology challenges and proposed solutions for affordable Submarine Launched Intermediate Range Ballistic Missiles (SLIRBMs), including launch considerations and potential payloads. Responses to this RFI will be used by the Government to select presentations to be given at the upcoming SLIRBM Technical Exchange or to otherwise be reviewed by the government.
The SLIRBM requirements include: 1. System must be affordable 2. Range - IRBM 3. Missile diameter - 32.5 inches maximum 4. Both conventional and nuclear payloads to be considered 5. Payload weights, diameters and length to be consistent with missile dimensions and range 6. Conventional payload system to have GPS accuracy 7. Missile subsystem hardened to Space Grade 8. Control of collateral damage to be considered (e.g., stage debris control) 9. Intermediate range ballistic missiles, including their payloads, and all of the launcher subsystem except for electronics, are to be contained within the 86 inch diameter TRIDENT missile launch tube 10. Usable missile tube length (for missile, payload and launcher) ? 36 feet maximum.
The Strategic Systems Programs (SSP), SLIRBM Integrated Product Team held a SLIRBM Technical Exchange in the SSP Management Center on 22 September 200. Representatives from Industry (limit, three members per company) are encouraged to attend. At this technical exchange, SSP presented detailed Navy requirements, current and future technology plans, and ongoing programs. In the interest of assisting SSP in developing a comprehensive SLIRBM project plan; industry was encouraged to participate in one or both of two manners: first by presenting information they believe germane at the Technical Exchange, and second, by submitting detailed concept papers explaining their approach and technical solutions for a SLIRBM, including cost drivers. Information relating to IRBM applications on surface ships is also sought. Those offering the first approach submited an abstract of their proposed remarks containing the following information: a) current programs, b) future plans, and c) technology challenges and solutions.
For all inputs: presentations, concept papers, or one-on-one briefings, information that comprehensively addresses the three technical areas of missile, payload, and launcher in a system context are desired. However, inputs that only address any one or two of these areas separately also are desired. The requirement is to consider both conventional and nuclear payloads. In doing so, if respondents believe the nuclear option is affecting affordability substantially, they are requested to separate the two payload areas so that the affordability of the conventional payload case may be understood clearly. Similarly, respondents may present only the conventional or the nuclear payload case if their expertise is limited in this manner."
Wenn ich das richtig interpretiere, soll die Rakete also einen Durchmesser von max. 32.5 Inches haben und zusammen mit einem Startcontainer in die 86 Inch mal 36 Fuß große Abschußvorrichtung der Ohios (wohl der zu SSGN umgebauten) passen. Diese IRBMs entspringen wohl der Mini-nuke-Konzeption von Rummy, denn mit einer Trident kann man einen einzelnen Schurkenbunker nicht ohne extrem heftige Kollateralschäden plattmachen. Mit einer Mini-nuke erhofft sich Rummyboy das wohl. Zudem wäre es natürlich billiger als die teuren Tridents.
