Sostiene Mauricio
no es más que una sociedad de LM con Boeing, como el F-22 lo hace LM y el F-15 lo hace Boeing.


El ejemplo seria si los aviones fueran de Boeing, los mecanicos de tierra fueran de boeing, los pilotos de boeing y la USAF se limitara a entregarle a Boeing una bomba y a decirles "tiramela en ese puente, tu sabras como".

Otra cosa diferente es que dentro de ese 76% haya un porcentaje de módulos que se hayan adquirido de fabricantes Rusos.


No te creas, yo conozco dos o tres locales de copas donde pagando soy guapisimo. :mrgreen: Asi que ahora ya lo que cuenta es la propiedad, no la fabricacion. Asi que si mañana Emiratos o Arabia Saudi compra la ISS se convierten en los mejores constructores de cosas orbitales ¿no?

Si fuera tan sencillo y barato como soplar y hacer botellas

No te creas. Yo si pienso que llegaron. Y ademas varias veces. :conf:

Tan solo te digo que es muy diferente contar la ISS segun quien paga y segun quien diseña y construye. Prueba a hacerlo por esa segunda via, veras que risa.

No veo cuál es la risa. Por contenido sigue siendo un affair mayormente Ruso-Americano. Y en cualquier caso el módulo más grande de todos es Japonés. Calcula tu que la cacerola se ha construído mediante lanzamientos de dos Proton-K y dos Soyuz-Progress... y diez misiones del Shuttle. Diez de catorce en total. O sea...

Pues no. No es mas que un carguero. Muy bueno, eso si, pero practicamente igual que el Japones y que el proximo ruso. De hecho, este es el segundo ATV que sube a la orbita. El anterior fue el Jules Verne. Que conste que a mi me gusta mucho el ATV y posiblemente se pueda sacar de el una buena nave orbital, pero al dia de hoy solo es un carguero. Es superior a HTV2 en que sus sistemas de acoplamiento son automaticos, mientras que el japones requiere que se le acople a mano. O a brazo. Porque lo tienen que enganchar con el Canadarm y llevarlo a la exclusa. Eso siempre requiere un tipo.
Los rusos estan preparando su propio carguero, pero mientras tanto han renovado sus soyuz con las TMA. Son mas pequeñas, pero por ahora son capaces de mantener el tipo sin problemas.
Quien no tiene nada en este segmento... son los USA, que carecen de capacidad de transporte al espacio fuera del Shuttle. Y, lo que es mas grave, no estan trabajando en algo de este estilo, aunque es de suponer que podrian utilizar alguna de sus naves con astronautas para el traslado de carga. Aunque esto ultimo seria carisimo.

USAF Space, Bomber Programs Move Forward

Feb 15, 2011

By Amy Butler

The U.S. Air Force is sacrificing part of its Global Hawk unmanned aerial system program while proceeding with a more aggressive buy of satellites and rockets, and moving forward with a bomber program.

The Air Force is proposing in its fiscal 2012-16 budget to cut $428 million from its Global Hawk Block 40 program, which aims to put an active, electronically scanned array (AESA) radar on the high-flying unmanned aerial system (UAS) to collect data on moving targets on the ground and in the air. The Northrop Grumman/Raytheon radar also is capable of taking highly accurate synthetic aperture radar images through weather and dust.

Service officials originally planned to buy 22 of the Block 40 aircraft; the Air Force now plans to buy 11, says USAF budget deputy Marilyn Thomas. This cut will undoubtedly drive up the per-unit cost of the aircraft. It is unclear whether this will trigger yet another breach of program cost limits in the Nunn-McCurdy statute.

Meanwhile, the service is requesting $166.3 billion in fiscal 2012. Of that the so-called blue top line — excluding defense health and contingency spending — is about $119 billion, according to Maj. Gen. Alfred Flowers, deputy assistant Air Force secretary for budget. Roughly 16% of that is dedicated to research and development with 19% for procurement.

Some day-to-day expenses, such as fuel, have gone up. The Air Force paid for this in part with nearly $33.3 billion shaved from the projected budget through fiscal 2016. The fiscal 2012 budget requests three Global Hawk Block 30 aircraft at $485 million and continues Air Force research at $423.5 million, with another $549 million requested for the Navy’s Broad Area Maritime Surveillance version.

“Efficiencies have certainly been used to enhance warfighting and readiness in this budget,” Flowers says.

After a two-year hiatus as an official program, USAF is dedicating $3.7 billion for the so-called Long-Range Strike family of systems, the bulk of which will be dedicated to a penetrating, nuclear-capable bomber. This includes about $200 million in fiscal 2012, roughly the same amount as last year, to keep technology developing until a proper program is restarted. Defense Secretary Robert Gates put the brakes on the project two years ago to review requirements and assess options; some in the Pentagon were concerned USAF would craft an unrealistically ambitious program that would crater from overreaching for technology. However, details on the requirements, forthcoming request for proposals and schedule are unlikely to be publicly discussed.

Gates said last month he would like for the bomber to be “optionally manned,” meaning it can be flown remotely when needed. Boeing, Lockheed Martin and Northrop Grumman are likely to be competitors for this work.

The fiscal 2012 proposal also increases production of Reaper UAS at General Atomics to 48 per year, the maximum rate the factory can handle for Air Force purchases, and 36 Gray Eagle variants per year for the Army. USAF plans to buy 396 aircraft, and the fiscal 2012 request is for nearly $1.1 billion. The Army request is $806 million.

USAF’s plans to buy a new high-performance trainer appear to be on the back burner in the fiscal 2012 request. Flowers says $307 million is outlined across the future years’ defense plan (FYDP). Though funding begins in fiscal 2012 based on the request, there are no procurement quantities listed. Alenia, BAE Systems and Lockheed Martin/Korea Aerospace Industries are all readying existing designs in anticipation of a competition.

USAF’s request removes 57 conventional-takeoff-and-landing (CTOL) F-35s in accordance with the delay and funding cut handed down by Gates. The aircraft will reach the service later than planned, and the Air Force has outlined about $25 million to study how to conduct a life-extension program for the F-16, which the Joint Strike Fighter will replace.

Perhaps the most significant shift in the service’s Fiscal 2012 budget request is a new approach to purchasing highly expensive satellites and rockets that are needed for military operations and civilian purposes, such as air traffic control and financial transactions. The Pentagon is proposing to even out purchasing of satellites from various manufacturing facilities. This will begin with a phased purchase of Advanced Extremely High Frequency (AEHF) communications and Space-Based Infrared System (Sbirs) missile warning satellites. The plan is to buy two AEHF satellites (5 and 6) in Fiscal 2012. Officials did not cite the total cost per satellite for AEHF and Sbirs, but $550 million would be set aside for the AEHF in fiscal 2012 as a first payment, with more payments to follow. Another $185 million would be set aside in advance procurement for the next two Sbirs spacecraft (also 5 and 6). The full buy of those two Sbirs spacecraft would come in Fiscal 2013, Flowers says, adding they are estimated to cost $555 million. If realized, this would be a dramatic reduction in the per-unit cost, which is now estimated at $1.3 billion. Both AEHF and Sbirs are manufactured at Lockheed Martin’s Sunnyvale, Calif., facility, and Pentagon procurement chief Ashton Carter says the goal is to stabilize work to reduce the changes of work stoppages and loss of critical skills.

The Pentagon also plans to stabilize funding for the Evolved Expendable Launch Vehicle (EELV) program beginning in fiscal 2012. The Pentagon goal is to buy a total of five of the Atlas V and Delta IV rockets annually rather than three as in previous years. In fiscal 2012-13, the Air Force will buy four, with the Navy requesting one. In fiscal 2014, USAF will buy all five boosters. The price of the program is expected to go up, largely owing to the cost of operations and services from manufacturer United Launch Alliance.


USAF also is starting research funding for the Defense Weather Satellite System (DWSS) in fiscal 2012 at $444.9 million; this will provide the defense portion of the now-defunct National Polar-orbiting Operational Environmental Satellite System.

Other USAF budget highlights are: $877.1 million for development of a KC-135 replacement plus acquisition of 10 HC/MC-130Js, one C-130J, nine C-27Js, 19 F-35As, 6 CV-22s (including one in the war contingency budget), nine Light Attack Armed Reconnaissance aircraft, four HH-60G Pave Hawks (including one in the war contingency budget) and two Common Vertical Lift Support Program (CVLSP) helicopters.

Meanwhile, the service also is struggling to keep some programs alive as the government continues to operate at fiscal 2010 levels because Congress has failed to approve budgets for fiscal 2011, which ends Sept. 30. The purchase of AESA radars for F-15 fighters is one project affected by the lack of funding in fiscal 2011, Flowers says. If the funding is not provided, the service could be forced to ground F-15s owing to parts obsolescence in the old, mechanically-steered radar.

Also considered a “new start” in fiscal 2011 and needing funding are the GPS III procurements of Satellites 3-4. USAF requested an $80 million reprogramming late last year to provide funding for long-lead parts for Satellites 3-4; the funding is being pulled from the account for purchasing AEHF Satellite 4, which will cost “less than what was budgeted,” the request document says. Without funding to avoid a production gap, the GPS III program faces a one-year slip.

USAF also is pushing to reprogram $63.1 million to purchase C-5 Reliability Enhancement and Re-engining Program (RERP) kits. Without the funding, “the Air Force will be forced to reopen the contract for negotiations resulting in a significant cost increase to the United States Government,” that reprogramming request states.

Tales From The Crypt

Posted by Bill Sweetman at 2/15/2011 9:33 AM CST

The FY2012 budget and surrounding materials point to confirmation of what was first reported here back in 2008: that the USAF's development of a new bomber draws on major classified development programs in the area of large, extremely low observable (ELO) aircraft. However, it might not have been quite the aircraft we thought it was.

The USAF consistently refers to its new bomber as based on "proven technology" but there is no known basis of proof for its most important single feature: a degree of stealth high enough to assure survival in a heavily defended area, combined with affordability in manufacture and support. Since the USAF is now more or less openly referring to a classified precursor program, that is most likely its key feature.

The classified segments of the budget are certainly large enough to support such a program. While in the old days you had to track down tell-tale line items and add the printed budget numbers, the Pentagon is now open about its secrets, with a "classified programs" line-item in the P-1 budget book.

A rough estimate is that the Pentagon's classified programs and operations would count as the world's sixth-largest defense budget. Readily searchable line items in the budget add up to more than $57 billion, more than Germany's entire spending.

Most of this appears in three line items: Over $18.5 billion in USAF procurement, a single $17-billion plus line in the defense-wide operations and support budget, and almost $18 billion in research and development. Most of the R&D funding is in the USAF budget; in fact, two-thirds of USAF R&D is classified.

Adding up readily-identifiable secret line-items yields a USAF black budget of $33.1 billion in R&D, operations and procurement accounts. The USAF also states that its "non-blue" budget for fiscal 2012 - predominantly intelligence, surveillance and reconnaissance - is $30.9 billion, leaving a clear $2.2-plus billion for non-ISR programs.

However, it's likely that precursors to the bomber also reside in the ISR accounts - for example, that's where the RQ-170 Sentinel would be found. There remains a requirement, for example, for a large stealthy ISR UAV, described in the 2009 USAF UAV flight plan as MQ-La, to be available by 2020:

"Filling urgent COCOM needs first, the MQ-La, with SAR/GMTI [and] advanced SIGINT capabilities, will complement the Global Hawk in multi-INT ISR missions."

The advent of a system that could perform such a complementary role also goes some way to explain why the radar-carrying Block 40 Global Hawk has been cut back and some of its funding redirected to an electro-optical capability. It's quite possible - in the light of these developments - that the major Northrop Grumman activity observed starting in 2008 is actually an ISR program with relevance to a future bomber, rather than a bomber itself.

Pues si. El HTV. Y ya llevan dos viajes a la ISS. Es un poco mas pequeño, pero existir existe. Aqui va una comparativa de los cargueros actuales.

Lo que no es, es plenamente automatico. Se aproxima a la ISS de manera automatica, pero el acoplamiento se realiza con el brazo de la ISS. Este captura el modulo y lo lleva a la esclusa de aire.
Aqui tienes la maniobra

Pero no me seas pillin, que tu dudabas que los japoneses tuvieran siquiera algo parecido a la Progress. Y resulta que tienen un cacharro fantastico. Y lo que es mas importante, un cohete con el que lanzarlo.:twisted:
