December 8 At the Washington Summit, President Reagan and General Secretary Gorbachev signed the Treaty Between the United States of America and the Union of Soviet Socialist Republics on the Elimination of Their Intermediate-Range and Shorter-Range Missiles, commonly called the Intermediate-Range Nuclear Forces Treaty, or INF. The treaty called for the elimination of all United States and Soviet ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometers.
January 15 President Reagan directed the Department of Defense to establish the On-Site Inspection Agency to meet the on-site inspection requirements of the INF Treaty.
January 26 The Department of Defense officially established the On-Site Inspection Agency as a separate operating agency reporting to the Under Secretary of Defense for Acquisition.
February 1 Brigadier General Roland Lajoie, U.S. Army, appointed as the first Director of the On-Site Inspection Agency.
February 8 Initial cadre of 40 military and civilian personnel joined the OSIA, moving into temporary office space at Buzzard Point, Washington D.C.
April Inspection and escort teams from OSIA began conducting mock INF inspections in the United States and Europe to develop procedures to be used when the INF Treaty entered into force and actual INF inspections and escort duties began.
June 1 President Reagan and General Secretary Gorbachev exchanged the articles of ratification for the INF Treaty, which put the treaty into effect and started a 30-day countdown until the first inspection could begin.
July 1 The United States and the Soviet Union began
continuous portal monitoring under the INF Treaty, with U.S. inspectors
monitoring a Soviet missile plant at Votkinsk, Russia, and Soviet
inspectors monitoring a missile factory at Magna, Utah.
July 1 A U.S. inspection team led by OSIA, with General Lajoie as a team member, conducted the first baseline inspection at Rechitsa, USSR, of Soviet INF facilities.
July 22 The Soviet Union conducted the first elimination of treaty-limited missiles under the INF Treaty, destroying an SS-20 missile at Kapustin Yar. Inspectors from OSIA observed the elimination.
September 8 The United States held its first INF elimination, at the Longhorn Army Ammunition Plant in Texas, with an inspection team from the USSR observing the destruction of Pershing missiles.
February 25 The On-Site Inspection Agency relocated to facilities at Dulles International Airport outside Washington D.C.
July 6 The United States completed the elimination of the shorter-range missiles covered by the INF Treaty, with the elimination of the last Pershing 1A missile.
July 12 The On-Site Inspection Agency received its first Joint Meritorious Unit Award, covering the period from January 15, 1988 through December 31, 1988.
July 26 The Soviet Union eliminated its final SS-12 missile, one of the shorter- range systems covered by INF.
August 16 The Soviet Union completed elimination of the SS-5 intermediate- range missile banned by the INF Treaty.
September 23 Secretary of State James Baker and Soviet Foreign Minister Eduard Shevardnadze signed the Wyoming Memorandum of Understanding (MOU), which called for a bilateral exchange of information and verification inspections for chemical weapons.
October 27 The Soviet Union completed the elimination of its shorter- range missiles with the destruction of the last SS-23 missile.
January At the continuous portal monitoring site in Votkinsk, Russia, the United States began installing the non-damaging Radiographic Imaging System (RIS, or CargoScan), which would image ICBMs exiting the factory to verify that they were not SS-20 missiles prohibited by the treaty.
February Soviet officials objected to various operating procedures for the new CargoScan X-ray system, voicing concerns over safety precautions, magnetic tape storage, and joint operating procedures.
March 1 With the CargoScan system installed and operational, the American monitoring team at Votkinsk requested to use the new system to image a railcar leaving the factory. The Soviets still had objections to some CargoScan operating procedures and denied the request, placing the railcar in a building near the plant to await a ruling.
March 9 At Votkinsk, Soviet plant officials removed the
railcar which had been set aside, along with two other railcars,
without allowing the American portal monitoring team to image them with
the CargoScan system. The U.S. inspectors were instead allowed to
visually inspect the cars. United States inspectors declared an
ambiguity and the issue was elevated to senior levels within the U.S.
government. United States Secretary of State James Baker lodged an
official protest with the Soviet government, leading the two countries
to send delegations to Votkinsk to resolve the dispute and agree on new
operating procedures. By the end of the month, the issue had been
resolved to both countries' satisfaction and the U.S. portal monitoring
team began imaging railcars with the CargoScan system.
May President Bush ordered the expansion of the On-Site
Inspection Agency and assigned the Agency responsibility for planning
inspection procedures for several proposed treaties: the Conventional
Armed Forces in Europe (CFE) Treaty, the Strategic Arms Reduction
Treaty (START), the Threshold Test Ban Treaty (TTBT), the Peaceful
Nuclear Explosions Treaty (PNET) and several chemical weapons
June 1 President Bush and General Secretary Gorbachev signed protocols to the TTBT and PNET, clearing the way for ratification of these nuclear test treaties.
June 1 The U.S. and USSR signed the Destruction and Non-Production Agreement, a bilateral accord which called for the two nations to destroy part of their chemical stockpiles and prohibited the further manufacture of chemical weapons.
June The OSIA conducted its first inspection under chemical warfare agreements added to the Agency's responsibilities the previous month, inspecting Soviet chemical facilities under Phase I of the Wyoming Memorandum of Understanding.
November 19 Twenty-two nations signed the Conventional Armed Forces in Europe (CFE) Treaty, which limited the amount of military equipment in Europe. The later collapse of the Soviet Union caused the creation of several new republics and brought the number of nations participating in CFE to 29. Later, Czechoslovakia dissolved into two separate nations to raise the number of CFE participants to 30.
December 11 Following ratification by the United States Senate and the Supreme Soviet, the Threshold Test Ban Treaty and the Peaceful Nuclear Explosions Treaty entered into force.
January 25 Major General Robert W. Parker, U.S. Air Force, became the new Director of the On-Site Inspection Agency, replacing Major General Lajoie, who departed for a new assignment.

July 6 An OSIA inspection team conducted the first on-site
event under the Vienna Document of 1990, an evaluation at Cherkassroye,
in the Kiev Military District of the USSR.
July 11 The Under Secretary of Defense for Acquisition designated OSIA as the Department of Defense Executive Agent for the United Nations Special Commission on Iraq. This gave the Agency the mission of supporting inspections of Iraqi chemical, biological and nuclear facilities conducted by the United Nations Special Commission on Iraq, which was established by UN Resolution 687 with the task of ensuring the elimination of Iraqi ballistic missiles and weapons of mass destruction. The OSIA coordinated DOD support to the Commission, consisting mainly of linguists, weapons experts, surveillance flights, and staff personnel.
July 31 President Bush and President Gorbachev signed the START I Treaty, which called for the reduction of strategic nuclear arsenals in the United States and the Soviet Union.
August 19 Hard-line Communists staged a coup in the Soviet
Union, ousting President Gorbachev. Democratic and reform elements,
particularly those led by Russian President Boris Yeltsin, thwarted the
coup and returned President Gorbachev to office.
November Russia declared a one-year moratorium on all underground nuclear testing. In the summer of 1992, following the nuclear test JUNCTION, the United States reciprocated, halting further scheduled nuclear tests. The moratoriums were later extended. While this moratorium did away with active monitoring of nuclear tests under TTBT and PNET, the treaties remain in effect and the OSIA remains ready to resume its nuclear test monitoring and escort duties.
December 25 Weakening of the Soviet government and the Communist Party, accelerated by the aftermath of the failed coup and a collapsing economy, resulted in several republics declaring their independence in early December. This caused the dissolution of the Soviet Union on Christmas Day. The former Soviet Union broke into several republics, most of which became members of the Commonwealth of Independent States, a loose alliance which retained ties between these former Soviet states while having
January Secretary of State James Baker announced
Operation Provide Hope. The near-collapse of the former Soviet Union's
economy brought hunger to many of the newly independent republics,
which led the United States to provide humanitarian relief through
Operation Provide Hope. Provide Hope supplied food, medical supplies
and other needed aid to the former Soviet republics. Due to its
experience in the Soviet Union, the OSIA was tasked to assist with the
delivery and distribution of aid.
February 10-26 The On-Site Inspection Agency supported Phase I of Operation Provide Hope. The Agency deployed 12 teams, consisting of a total of 38 people, to the former Soviet Union to distribute 2,200 tons of food and medical supplies to 25 cities.
March 6 A team of Russian test monitors observed the United States underground nuclear test JUNCTION under the Threshold Test Ban Treaty.
March 24 The Vienna Document of 1992 was signed by 51 nations. This agreement replaced the Vienna Document of 1990, mandating more stringent requirements for exchange of information, inspections of armed forces and monitoring of military movements and exercises than those called for by the previous version.
March24 Twenty-four nations signed the Open Skies Treaty, which allowed information-gathering overflights of participating countries by other signatories.
