DoD’s Plans to Change Ground-Based Missile Defense Systems. In April 2009 the Secretary of Defense announced plans to freeze the current number of ground-based interceptors in Alaska as part of the ground-based midcourse missile defense system that is intended to defend the United States against limited ballistic missile attacks from North Korea or Iran. The plan would continue funding for research and development to improve the nation’s ability to defend against long-range ballistic missiles. DoD also announced plans to upgrade six Navy Aegis warships to perform the ballistic missile defense mission at a total cost of $200 million. Moreover, on September 17, 2009, President Obama announced his cancellation of the previous Administration’s plans to field a high-resolution tracking radar in the Czech Republic and to deploy 10 ground-based interceptor missiles in permanent silos in Poland. In its place, the President proposed a four-phase plan. Phase One would rely on Block IA of the SM-3 missile, which would be deployed on existing Aegis warships. Phase One also would base an AN/TPY-2 radar in Europe to provide early detection and tracking of ballistic missiles if launched toward the United States. Phase Two would entail both sea- and land-based deployment of a more capable Block IB version of the SM-3 missile; Phases Three and Four would involve Block IIA and Block IIB missiles that are still under development. (Each block represents a major upgrade in capability from its predecessor.)Emelie Rutherford at Defense Daily (subscription only) has an article on the hearing, and picks up more details.
In a report published in February 2009, CBO discussed three alternatives to the previous Administration’s plans for ballistic-missile defense in Europe. Two of the three are similar to the current Administration’s revised plans. One alternative would use SM-3 missiles deployed on Aegis warships operating at three locations around Europe, supported by two forward-based tracking radar stations; another alternative would rely on land-based SM-3 missiles operating from mobile launchers located at two U.S. bases in Europe (Ramstein Air Base in Germany and Incirlik Air Base in Turkey), supported by two transportable radar units. The Administration’s new plan blends elements of these two options and encompasses both sea- and land-based deployment of SM-3 missiles.
For a sea-based concept, maintaining continuous coverage in three locations would require a total of nine ships (for each ship deployed, another would be undergoing maintenance and a third would be in use for training). CBO viewed the fiscal year 2010 request for $200 million to convert six warships as a first installment in pursuing an approach of upgrading existing warships (or proposed warships that would have been built to perform other missions) to provide missile defense. That approach would reduce costs relative to procuring new ships but would forgo the possibility of deploying those ships to other locations in the world where they could perform other missions. Alternatively, if new ships are needed, an option would be to adapt littoral combat ships for the missile defense mission with a specially developed Aegis module consisting of a version of the AN/SPY-1 radar and vertical launch system cells; CBO has estimated those ships would cost $650 million each.
In January 2009 (on the basis of the 2009 FYDP), CBO projected that total investment costs for missile defense would be at least $10 billion per year, peaking at $17 billion in 2018; unbudgeted costs could add another $4 billion annually. The Secretary announced in April 2009 that the ABL program would be limited to a single aircraft, that no additional ground-based interceptors would be deployed in Alaska, and that the Multiple Kill Vehicle program would be terminated. With those and other changes, the 2010 request for the Missile Defense Agency would be $1.4 billion smaller than the amount provided in 2009. Incorporating those changes, CBO now projects that total investment costs for missile defense would average about $8 billion annually through 2028, peaking at about $10 billion in 2014. The total savings, averaging $2 billion per year, include the specific savings from restructuring the ABL program as described above.
"So that's six out of what may ultimately be, in CBO's estimation, nine ships to do the mission," Goldberg said. "That's the lowest-cost way to do the mission...to take existing ships and convert them. The problem then is that you have nine ships dedicated to this mission, (they) can't do something else. That's the tradeoff."I have no feeling at all what the Obama administration is thinking about in regards to the next step with BMD, or if there even is a next step. I generally see the decisions made in ballistic missile defense so far as a step forward towards flexibility and better cost certainty, not to mention a transition towards functional systems instead of investment in futuristic systems. I also don't see any evidence more funding is coming to support the new ideas, but it is still early. It is interesting to see the CBO highlight the decisions so far have accounted for $2 billion in savings annually from FY11-FY28, roughly $36 billion.
Goldberg said if the Pentagon were to build nine new ships dedicated to the BMD mission, either DDG-51 Arleigh Burke destroyers or Littoral Combat Ships (LCSs) could be used.
Nine new DDG-51s could cost $19 billion. Taking nine LCSs and adding AN/SPY-1 radars and vertical launch-system cells would cost much less--approximately $9 billion, he said.
The Obama administration's new missile-defense plan brings some savings. Eliminating the previously planned radar in the Czech Republic and ground-based missile interceptors in Poland saves a total of $1.5 billion, Goldberg said. Yet he added the "biggest element that you put back in is the cost of your ships," which CBO estimates could run as high as $19 billion.
Here is part of the story. Nine new DDG-51s could cost $19 billion, as CBO says, but the question is whether nine new DDG-51s can meet the obligations of the proposed plan. This is the plan as listed on the White House website:
- Phase One (in the 2011 timeframe) - Deploy current and proven missile defense systems available in the next two years, including the sea-based Aegis Weapon System, the SM-3 interceptor (Block IA), and sensors such as the forward-based Army Navy/Transportable Radar Surveillance system (AN/TPY-2), to address regional ballistic missile threats to Europe and our deployed personnel and their families;
- Phase Two (in the 2015 timeframe) - After appropriate testing, deploy a more capable version of the SM-3 interceptor (Block IB) in both sea- and land-based configurations, and more advanced sensors, to expand the defended area against short- and medium-range missile threats;
- Phase Three (in the 2018 timeframe) - After development and testing are complete, deploy the more advanced SM-3 Block IIA variant currently under development, to counter short-, medium-, and intermediate-range missile threats; and
- Phase Four (in the 2020 timeframe) - After development and testing are complete, deploy the SM-3 Block IIB to help better cope with medium- and intermediate-range missiles and the potential future ICBM threat to the United States.
The SM-3 is 21-inches in diameter and stands just over 21 feet tall, meaning it will only work on MK41 SL (Strike Length) VLS cells which is about 25 ft tall.. This brings up something interesting, because the brochures of the General Dynamics version of the Littoral Combat Ship Multi-Mission Combatant (PDF) was reported by DID to be outfitted with Strike Length VLS, while the Lockheed Martin version of the Littoral Combat Ship Multi-Mission Combatant (PDF) only comes with Tactical Length VLS, which are about 18.5 ft tall. The LCS option also requires reliance on external radar systems, as both LCS MMC versions use the SPY-F radar, unable to track ballistic missiles successfully for intercept.
I also wonder what CBO means by LCS AEGIS module, because that sounds like it can be swapped in and out. Somehow, I don't think that is what they meant. I think they meant AEGIS version of the LCS, or the LCS MMC.
The SM-3 Block IIB is brand new, so how can the CBO predict costs of something that doesn't exist? Suggesting cost savings on an non-existent defense system is the kind of math one can only find in government (businesses that do it go out of business). It is like giving me a quote for Cinderella's necklace or Snow Whites bracelet. The SM-3 Block IIB may be where the DoD replaces the unitary warhead with the Multiple Kill Vehicle warhead, which is great, but how the SM-3 Block IIB manages the potential future ICBM threat to the United States is a huge question mark. Up until now everyone has been saying that any interceptor the US Navy uses to intercept ICBMs will be too tall and/or wide for the MK41. The KEI, for example, was reportedly 40 inches in diameter and almost 39 feet in length.
What has changed to make the SM-3 of any known type capable of ICBM intercept? My guess, nothing. The only thing I can think of is the SM-3 Block IIB might be specific for working in the MK57, which can give the missile greater diameter and support the additional height/weight of a MKV warhead. Other than that, the Navy is going to need a new launcher to support a SM-3 IIB in 2020 capable of meeting the same capability projected for the GBI, which although unproven, was expected to reach IOC by 2015.
So what do we know? We know CBO expects the new ballistic missile defense program to save an average of $2 billion annually for the next 18 budget cycles. We know the two options examined include an option for nine new DDG-51s for AEGIS BMD at an estimated cost of $19 billion, and a LCS MMC option estimated at 9 hulls approaching $9 billion. With savings of up to $36 billion by FY 2028, there would still be cost savings, but whether capability is the same requires quite a bit of religion.
With $36 billion the Navy could set BMD for the next 40 years with political support. It could help pay for the CG(X) and new BMD radars that have been looked at. The money could be used to help upgrade the DDG-1000/CVN-21 X-Band radar systems (same radar on both ships) to integrate into the existing AEGIS BMD network. The money could be used to develop a baseline hull for both CG(X) and DDG(X) ships that streamline future BMD ship costs across the fleet. There is a lot that could be done with that kind of money.
What shouldn't be done is investment into more DDG-51s after FY 2015, if not sooner. If the Navy is going to build new ships for BMD, get ships with the new radars and enough power to do the complex calculations for BMD in real-time. I don't think the DDG-1000 hull is the answer, and I don't believe nuclear power is necessarily a requirement (although may be desirable), but both may be options worth looking at and learning from.
While I would like to see more information before making a judgment call, I think the idea of using a modified LCS MMC hull for BMD intercept is not a bad idea at all. For a long time the 21st century plan for Navy BMD was to get radar systems on capital ships, like aircraft carriers and cruisers, and use a bunch of smaller ships as distributed shooters to give greater protection over larger areas from ballistic missiles. The idea is still sound, but it only works if you get the radar side of the equation right first, and that has meant CG(X) for several years now.
