trying to buildup its military arsenal. Brown also assert that in order to prepare for the worst-case scenario such as event like "First Strike" the United States therefore must be ready at anytime and any-event and would eventually deter whatever worst-case situation that eventually will come-up in the future. Part of this Brown continue his effort to buildup the Strategic Air Command Nuclear Triad arsenal that Brown already started during his tenure as Air Force Chief of Staff and emphasize the need of a new and modern bomber aircraft such as the B-1B Strategic Bomber Aircraft and the new MX Intercontinental Ballistic Missile. Together with Secretary of Defense James Schlesinger Brown began the study and development for a new and sophisticated weapon to deter any possible threat in the future. However following the new Détente policy that was adopted in the early 1970s, Brown also adjust how to keep the United States Military always in robust shape and always ready all the time while following the Détente policy. Part of the Détente policy was the Strategic Arms Limitation Talks treaty or also known as SALT treaty which has already started in 1972, two years before Brown assuming the Chairman of the Joint Chiefs of Staff Position. Working together with Secretary of Defense James Schlesinger, Brown re-asserted that although both United States and Soviet had begun to talk for Détente and SALT treaty but always still be ready at any time and to prevent an event that eventually could lead to a major crisis and escalate the tension between United States and the Soviet Union. In November 1975, following James Schlesinger's retirement as Secretary of Defense and replacement by Donald Rumsfeld, Brown worked together with Rumsfeld to re-assert United States policy on military buildup and Détente. Both Rumsfeld and Brown agreed to work to speed up the B-1B Bombers Program in order to make B-1B Bomber Aircraft ready for service within the United States Air Force as soon as possible. Together with Secretary of Defense Donald Rumsfeld, Brown tested the B-1B Aircraft on a flight-test in 1975 along with Rumsfeld. Another part that Brown and Rumsfeld agreed was the new Fighter Aircraft program to modernize Air Force Tactical-Fighter Aircraft and to replace some Air Force aircraft that was considered obsolete. As a result, the Air Force finally receive the new Tactical-Fighter Aircraft, F-15 and F-16, although the program has been studied
