The 58th Reconnaissance Squadron is an inactive United States Air Force squadron. Its last was assigned to the 9th Weather Reconnaissance Wing at Kirtland Air Force Base, New Mexico, where it was inactivated in 1974. ==History== Activated in early 1943 under Fourth Air Force; spent World War II in the United States as an Operational Training Unit (OTU), initially equipped with P-39 Aircobras for advanced fighter training. Reassigned to Third Air Force in 1944, becoming a Replacement Training Unit (RTU) for A-36 Apache fighter-dive bomber ground attack aircraft. Reassigned to Stuttgart AAB, Arkansas in 1945 and realigned into a long-range strategic weather reconnaissance squadron, training with B-25 Mitchells and long-ranger P-61C Black Widow Night Fighters modified for weather reconnaissance missions. Reassigned to Rapid City AAB, South Dakota in late 1945, using P-61Cs as part of a NACA/Air Weather Service Thunderstorm Project to learn more about thunderstorms and to use this knowledge to better protect civil and military airplanes that operated in their vicinity. The P-61's radar and particular flight characteristics enabled it to find and penetrate the most turbulent regions of a storm, and return crew and instruments intact for detailed study. Inactivated in 1946 as part of the general demobilization of the AAF. Reactivated as part of Strategic Air Command in 1951 in Alaska, Equipped with very long range WB-29 Superfortresses 1951, upgrading to extended long-range WB-50D Superfortresses in 1956. Conducted long-range weather flights over the Arctic and along the northern periphery of the Soviet Union; the aircraft being equipped with sensors for detecting radioactive debris to gather evidence when the Soviets tested nuclear devices. Inactivated in 1958 as part of the phaseout of the WB-50s from SAC and development of faster jet aircraft for the long-range intelligence mission. The squadron was reactivated in 1963 at Kirtland Air Force Base, New Mexico, assuming the assets of the discontinued 1211th Test Squadron.〔''See'' Mueller, p. 292 (discontinuation of 1211th at Kirtland)〕 The squadron was equipped with twelve RB-57F Canberra (later WB-57F) reconnaissance aircraft. Most of the RB-57Fs were converted B-57Ds (a few were B-57Bs) equipped with two TF33 engines in place of the B-57B's J65, plus a pair of auxiliary J60s for high altitude and long range reconnaissance.〔Knaack, p. 337〕 Part of their duties involved high-altitude atmospheric sampling and radiation detection work in support of nuclear test monitoring. Over the next decade the RB-57Fs were flown on a worldwide basis at very high altitudes at high speeds. Stress cracks began appearing in the wing spars and ribs of the RB-57Fs after a few years of service. Some were sent to General Dynamics for repairs. Due to the excessive cost of repairing all the aircraft, nine were placed in storage at Davis-Monthan Air Force Base, Arizona in 1972. The 58th WRS, the last squadron in the Air Force to use the WB-57F Canberra, was inactivated on July 1, 1974 after placing its planes in storage at Davis-Monthan. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「58th Weather Reconnaissance Squadron」の詳細全文を読む スポンサード リンク
