U.S. Nuclear Posture at a Crossroad, Defense Science Board Says

The Defense Science Board concludes in a new report that the United States has lost its “national consensus” on what the nation’s nuclear deterrent should look like and the role it should serve. The consensus has been replaced by an “entrenchment” of “sharp differences” of opinion. Therefore, urgent action is needed by the White House and senior leaders to “engage more directly to articulate the persuasive case” for how modern nuclear weapons serve U.S. national security policy.

U.S. nuclear policy has come to a crossroad because the current formula is no longer sustainable.

Perhaps not coincidently, the DSB report comes as the administration is preparing to persuade Congress to pay for a new nuclear weapons complex (Complex 2030) to resume production of nuclear weapons for the first since since the end of the Cold War. To that end, the report presents a wide range of recommendations for how to revitalize the U.S. nuclear posture.

Recommendations for nuclear weapons policy and forces include:

1. Leaders should declare “unequivocally and frequently” that nukes are still needed.
2. Establish a Red Team to look for nuclear enemies.
3. Establish a Deterrence Team to figure out how to better deter current and future adversaries.
4. The missile defense under construction is inadequate to deal with countermeasures and needs to be upgraded.
5. Accelerate development of “a credible Nuclear Leg of the Strike Triad.”
6. Figure out what to do with nuclear forces beyond the SORT treaty, but hedge (it is now called “remain reversible”) against negative developments in Russian and China.
7. Modernize the command and control system.
8. The Nuclear Weapons Council should establish a policy that no single warhead type makes up more than 20 percent of the deployed stockpile (i.e., the stockpile should consist of at least five different warhead types).
9. RRW-1, as the first Reliable Replacement Warhead prototype is called, should be a full weapons program.

Recommendations for the nuclear weapons production complex include:

1. Produce “a predetermined number of RRW-class warheads” per year by 2012.
2. Create a National Nuclear Weapons Agency to support Complex 2030.
3. Retain all three nuclear weapons labs.
4. The Secretary of Defense should figure out which is easier: sustain the current quantities and diversity of nuclear weapons or build new ones.
5. Create an Assistant Secretary of Defense for Strategic Weapons with a Deputy Assistant Secretary of Defense for Nuclear Weapons.
6. Get congressional approval to appoint the Deputy Secretary of Defense as the Nuclear Weapons Council and make the commander of STRATCOM a member of the Nuclear Weapons Council.

Yet Another RRW Vision?

One of the surprises in the report is that the DSB seems to have a different long-term vision for the RRW than the administration. A drawing in the DSB report shows how the composition of nuclear warheads would change with the introduction of RRWs. The drawing a future mix of equal numbers of RRWs and existing life-extended warheads (see figure below).

DSB Stockpile Vision

The Defense Science Board report presents a nuclear stockpile vision that includes roughly equal numbers of the RRW and life-extended warheads.

That vision is very different from the one presented by the Secretary of Energy, Secretary of Defense, and the Nuclear Weapons Council in their joint interim RRW report to Congress in March 2006. A drawing in that report showed a future mix of warheads where RRWs would replace all life-extended warhead types (see figure below).

DOD/DOE Stockpile Vision

The Department of Energy and Department of Defense vision for the nuclear stockpile includes a phaseout of all life-extended warheads leaving only RRWs.


The DSB report comes across as an attempt to “resell” the 2001 Nuclear Posture Review. It is a report on the defensive that suggests that critics of Cold War nuclear policy and excessive capabilities have had a considerable impact on U.S. nuclear policy and the mood inside the administration and Congress.

A major shortfall of the report is this: Despite lamenting that new thinking is urgently needed, the DSB report offers no new ideas for why it is necessary to revitalize the nuclear posture, except the arguments made in the 2001 Nuclear Posture Review and the 2004 DSB report on the future of strategic forces. Instead of defining the new agenda, the DSB report appears to be defending the current agenda.

This is perhaps not surprising considering that the entire DSB Task Force consisted of people from the nuclear labs, major defense contractors and conservative think tanks. Some were even the architects of the 2001 Nuclear Posture Review. All advisors are from the Pentagon, the nuclear agencies, and the nuclear labs. The DSB report’s primary conclusion is that new thinking is needed, but the list of participants and briefings received strongly suggests that no attempt was made to think “outside the box.”

The failure to involve others and new ideas is perhaps the worst enemy of U.S. nuclear policy, not to mention a disfavor to national and international security.

    AS: I suggested to outgoing NNSA Administrator Brooks that public meetings regarding declassification initiatives had been found to be very helpful in the past and that he might consider doing the same in the future. The same thought goes for my endorsing your idea that the public needs to be able to participate in the development of strategic options for the future of the nation’s nuclear weapons programs. The weapons labs., pentagon, contractors and DOE have good people with good ideas.

    But they need to hear the ideas of those outside those tightly wound loops. This is not only for the value of the ideas that might be brought into the process, but too, the possibility that there would be some learning on the part of those currently not a part of the in group.

    Yes, classification might be a limiting factor, but DOE, with DOD’s help, has already demonstrated that on matters as sensitive as classification policy itself the public can participate without danger to classified information and contribute extremely valuable information and perspectives to the process.
