CFE : Conventional Forces in Europe Treaty

On November 19, 1990, delegates from 22 countries gathered in Paris to sign the Treaty on Conventional Armed Forces in Europe (CFE). The agreement, which took over 20 months to negotiate, is designed to reduce the threat of a massive conventional offensive strike through the heart of Europe. The CFE Treaty accomplishes this by limiting five types of conventional weapons: tanks, armored combat vehicles, artillery, attack helicopters and combat aircraft.

The legally-binding treaty places limits on two groups of states in Europe. The first, known as the Western Group, is comprised of those countries that were members of the North Atlantic Treaty Organization (NATO) at the time of the Treaty's negotiation. The second, known as the Eastern Group, is comprised of those countries that were members of the former Warsaw Pact. Each group is permitted 30,000 armored combat vehicles, 20,000 artillery pieces, 20,000 battle tanks, 2,000 attack helicopters and 6,800 combat aircraft. These group limits are further subject to zonal limits formed by concentric circles extending outward from the center of Europe. The Treaty requires each group to determine how to divide its respective allocation up among group members. A politically-binding side agreement known as CFE-1A also places limits on combat manpower in Europe.

Implementation Progress

The CFE Treaty provisionally entered into force on July 17, 1992; complete entry into force followed on November 9, 1992. Despite dramatic political changes since the Treaty was signed, such as the dissolution of the Warsaw Pact and the Soviet Union, implementation of the CFE Treaty by its now 30 States Parties has been relatively smooth. Using treaty-defined reduction methods, States Parties were required to eliminate treaty-limited equipment (TLE) in three distinct phases: 1) 16 months after entry into force, at least 25 percent of each signatory's TLE above its numerical limitations had to be eliminated; 2) after 28 months, a 60 percent reduction of necessary TLE was required; and 3) after 40 months, 100 percent of necessary TLE had to be reduced.

Treaty provisions also include a multilayered verification system consisting of national or multinational technical means and on-site inspections during four time periods following entry into force: a 120-day baseline validation period; a 3-year reduction period; a 120-day residual level validation period; and a residual period for the duration of the Treaty. The on-site inspections include declared site, challenge, certification and reduction inspections.

The CFE Treaty obligates signatories to accept, without a right of refusal, a quota of passive declared site inspections during each phase. Each Party's quota is determined by a percentage of their objects of verification (OOV). An OOV is any formation at the brigade, wing, independent battalion, or squadron level holding TLE in service of the armed forces of any signatory, any TLE storage site or any TLE reduction site. Established passive declared site quotas for each State Party were 20 percent of OOVs during the first 120-day period, 10 percent during the 3-year reduction period, and 20 percent during the 120-day residual level validation period. Every year following the 120-day residual level validation period, established passive declared site quotas are 15 percent of OOVs for the duration of the Treaty.

Additionally, signatories conducted challenge inspections during the 120-day baseline validation period, the reduction period and the 120-day residual validation period with a quota up to 15 percent of the declared site inspections which that signatory was obliged to receive. For each year thereafter, the challenge inspection quota increases to 23 percent of the number of declared site inspections each signatory is obliged to accept. At a minimum, the Treaty requires each signatory to receive at least one declared site inspection per year and at least one challenge inspection per year. However, the inspected party has the right of refusal for any challenge inspection.

Certification of recategorization inspections and reduction inspections was also part of the CFE verification regime. Signatories did not have the right to refuse these inspections, which did not count against the quotas for declared site or challenge inspections. Increased numbers of East-on-East inspections, as a result of the dissolution of the Warsaw Pact, had negative implications for the Western Group. Because each signatory had to accept only a fixed quota of inspections, every East-on-East inspection reduced opportunities for West-on-East inspections. In order to remedy this problem, in July 1993, the Western Group (NATO) began permitting Eastern states to join in West-on-East declared site inspections and reduction inspections. A reciprocal offer by Eastern states to have Western states join Eastern-led inspections was initially declined by NATO in order to discourage East-on-East inspections. Only after achieving some success in reducing East-on-East inspections did NATO decide to allow Western states to participate in Eastern-led inspections.

The duration of CFE Treaty implementation is unlimited. Forty-six months after entry into force (May 1996), the signatories convened the first CFE Treaty Review Conference during which they agreed to begin the process of adapting the Treaty to the new security situation in Europe. The States Parties defined the "scope and parameters" of Treaty adaptation in setting out the terms of reference for the CFE adaptation negotiations which began in January 1997. Among the various changes that could result are: bloc-to-bloc ceilings being replaced by national ceilings (indigenous forces) and territorial ceilings (indigenous and stationed forces); reductions in NATO ground TLE and TLE in storage sites; sub-ceilings involving the states recently invited to join NATO (Poland, Hungary and the Czech Republic); and enhanced verification and transparency measures that have not yet been defined. On July 23, 1997, the CFE Joint Consultative Group reached an agreement in principle concerning CFE adaptation. If formalized, the agreement could lead to lower national ceilings, a new round of baseline validation inspections, and additional reduction and certification inspections.

Executive Summary

      • Talks began in January 1997.
        • Will focus on such issues as national versus group limits, the zonal structure, accession to the Treaty by non-members, and possible new TLE limits.
      • In February 1997, NATO formally tabled an adaptation proposal calling for:
        • Reductions in overall equipment entitlements throughout the AOA.
        • A system of national and territorial equipment ceilings to replace the current group limits structure.
        • Modification of the category of "designated permanent storage sites (DPSS)."
        • Additional measures to provide stability and greater transparency.
      • At the Helsinki Summit in March 1997, the US and Russia agreed to accelerate adaptation negotiations with a view to concluding a framework agreement setting forth the basic elements of an adapted treaty by late spring or early summer 1997.
      • July 1997: All 30 States Parties formally approved the text of a paper on the "Basic Elements for Treaty Adaptation" to guide further adaptation negotiations. Key elements:
        • Bloc-to-bloc structure to be replaced by national and territorial limits.
        • No increase in total TLE in the AOA.
        • New verification transparency measures likely.
        • Flank Agreement remains in effect.
        • Open to accession by new parties.
