In response to Section 1247 of the National Defense Authorization Act for Fiscal Year 2016 (Public Law 114-92)

This report is submitted in accordance with Section 1247 of the National Defense Authorization Act for Fiscal Year 2016 (Public Law 114-92).

The New START Treaty entered into force on February 5, 2011. Under the Treaty, the United States and Russia were required to meet the following central limits on their strategic offensive arms by February 5, 2018:

  1. 700 deployed intercontinental ballistic missiles (ICBMs), submarine-launched ballistic missiles (SLBMs), and heavy bombers;
  2. 1,550 warheads on deployed ICBMs and SLBMs and warheads counted for deployed heavy bombers; and
  3. 800 deployed and non-deployed ICBM launchers, SLBM launchers, and heavy bombers.

Since the previous Section 1247 report was submitted, both parties to the New START Treaty successfully complied with the Treaty’s central limits, which took effect on February 5, 2018. This is reflected in the aggregate forces data exchanged subsequently by the parties:

The New START Treaty’s limitations on the size of the strategic nuclear force that the Russian Federation can deploy and the verification regime established by the Treaty both regulate competition and provide key data, information, and insights regarding Russian strategic nuclear forces. The Treaty also increases transparency, predictability, and stability in the U.S.-Russian strategic nuclear relationship.

Through its verification regime, the New START Treaty enables the United States to gain greater information and insight into Russia’s strategic nuclear forces. The Treaty mandates that both sides exchange data detailing the numbers, locations, and technical characteristics of all weapons systems and facilities subject to the Treaty. The 18 on-site inspections that are conducted by the United States each year under the terms of the Treaty allow confirmation of Russia’s declared data on the number of deployed and non-deployed strategic systems located at the inspected facility, the number of reentry vehicles on deployed ICBMs and SLBMs, and declared conversions or eliminations of weapons systems that have taken place. The New START Treaty also affirms the right of the United States to use its national technical means (NTM) in a manner consistent with generally recognized principles of international law for monitoring Russian activities—capabilities which provide the United States with another source of information that is used to confirm data from exchanges and inspections.

Without the data exchanges and the access through on-site inspections to Russian facilities subject to the Treaty, the overall effect would be a decrease in our knowledge of Russia’s strategic nuclear forces. The information provided through the Treaty’s implementation contributes to reducing the risk of strategic surprise, mistrust, and miscalculations that can result from excessive secrecy or decisions based on worst-case assumptions.

Under the New START Treaty, the United States can rebalance its forces and adapt to any future technical or geopolitical changes that could affect a given leg of the delivery system Triad, and to determine its appropriate nuclear force structure. The Treaty provisions state that “each Party has the right to determine for itself the composition and structure of its strategic offensive arms.” The U.S. nuclear force structure is designed to account for possible adjustments in the Russian strategic force configurations.

Russia’s strategic forces are currently undergoing a comprehensive modernization in their force structure, operations, and planning. In a March 1, 2018 speech, President Vladimir Putin spoke about the development of five new nuclear-armed systems: a nuclear-powered, nuclear-armed cruise missile; a nuclear-powered unmanned underwater vehicle with intercontinental range; an air-launched ballistic missile; a “gliding wing unit”; and a heavy ICBM. Russian official commentary and media reports indicate that some of these systems could be fielded before New START is scheduled to expire in February 2021. The United States is monitoring the development of these systems and raised them with Russian officials. The New START Treaty’s Bilateral Consultative Commission, which meets twice annually, has provided the United States a forum in which to raise questions about Russian strategic force developments. Russia’s large stockpile of nonstrategic nuclear weapons is not subject to the Treaty’s limits and verification regime.[1]


The New START Treaty’s limits on Russia’s strategic nuclear force, establishment of data exchanges including the locations, numbers, and technical characteristics of weapons systems and facilities, and its verification provisions, which grant the United States access to Russian facilities containing deployed or non-deployed strategic systems, contribute currently to the national security of the United States. These provisions in the New START Treaty provide predictability, transparency, and unique insight with respect to Russian nuclear forces and planning as Russia continues to modernize its strategic nuclear forces. In so doing, it moderates strategic competition. The New START Treaty allows the United States to both retain and modernize its nuclear Triad while also providing the United States with the flexibility to adapt its force structure as needed.
