Beginning in 1980, the analog inlet control system was replaced by a digital system, which reduced unstart instances. This configuration had a second seat for the weapons officer and cut back the chines along the nose in order to fit the AN/ASG-18 Fire Control System and AIM-47A missile armament. Merely accelerating would typically be enough for an SR-71 to evade a SAM;[3] changes by the pilots in the SR-71's speed, altitude, and heading were also often enough to spoil any radar lock on the plane by SAM sites or enemy fighters. [43], The SR-71 featured chines, a pair of sharp edges leading aft from either side of the nose along the fuselage. For the same reason, the A-12 airframe was never used to construct a bomber, although Curtis LeMay expressed significant interest in this possibility. [22], In 1968, Secretary of Defense Robert McNamara canceled the F-12 interceptor program. [45], Aerodynamicists discovered that the chines generated powerful vortices and created additional lift, leading to unexpected aerodynamic performance improvements. [71][verification needed], Before takeoff, a primary alignment brought the ANS's inertial components to a high degree of accuracy. Bleed tubes and bypass doors were designed into the inlet and engine nacelles to handle some of this pressure and to position the final shock to allow the inlet to remain "started". On July 28, 1976, an SR-71A set an Altitude in Horizontal Flight record at 85,068.997 feet. The 1st Strategic Reconnaissance Squadron (1 SRS) kept its pilots and aircraft operational and active, and flew some operational reconnaissance missions through the end of 1989 and into 1990, due to uncertainty over the timing of the final termination of funding for the program. An SR-71 during a test flight handled by NASA. It has set numerous speed and altitude records including the following in chronological order. Cooper. It was located above and behind the student cockpit. During aerial reconnaissance missions, the SR-71 operated at high speeds and altitudes (Mach 3.2 and 85,000 feet, 25,900 meters), allowing it to outrace or entirely avoid threats. As the SR-71 had a second cockpit behind the pilot for the RSO, it could not carry the A-12's principal sensor, a single large-focal-length optical camera that sat in the "Q-Bay" behind the A-12's single cockpit. The SR-71 was driven by Bill Weaver with a Lockheed flight test specialist, Jim Zwayer in the back seat and it took off from Edwards AFB at 11:20 am . Paul Crickmore, Lockheed Blackbird: Beyond The Secret Missions, 1993, p. 233. The reactivation met much resistance: the USAF had not budgeted for the aircraft, and UAV developers worried that their programs would suffer if money was shifted to support the SR-71s. The gone but not forgotten Lockheed SR-71 Blackbird takes flight at sunset on its way to making a Mach 3.2 thunder run. The R-12 also had a larger two-seat cockpit, and reshaped fuselage chines. Quote from Reg Blackwell, SR-71 pilot, interviewed for "Battle Stations" episode "SR-71 Blackbird Stealth Plane", first aired on History Channel 15 December 2002. [11][127][128][129] Several aircraft have exceeded this altitude in zoom climbs, but not in sustained flight. An advanced, long-range, Mach 3.2 strategic reconnaissance aircraft. Water bottles had long straws which crewmembers guided into an opening in the helmet by looking in a mirror. "[122], Macke told the committee that they were "flying U-2s, RC-135s, [and] other strategic and tactical assets" to collect information in some areas. The SR-71 Blackbird is perhaps the most impressive plane ever built. Show more Show more 7:16 Lockheed SR-71 Blackbird. [49] Its "blue light" source star tracker, which could see stars during both day and night, would continuously track a variety of stars as the aircraft's changing position brought them into view. The investigation determined that the new aircraft would need to be supersonic and have a small radar cross-section. Retired USAF Colonels Don Emmons and Barry MacKean were put under government contract to remake the plane's logistic and support structure. Its stealthy design reduced its radar signature, and if it were fired upon by a surface-to-air missile, its evasive action was to simply accelerate and outfly the assailant. Wide-area imaging was provided by two of Itek's Operational Objective Cameras, which provided stereo imagery across the width of the flight track, or an Itek Optical Bar Camera, which gave continuous horizon-to-horizon coverage. Major sections of the skin of the inboard wings were corrugated, not smooth. The fact is that the real performances are still classified even today. The SR-71 originally included optical/infrared imagery systems; side-looking airborne radar (SLAR);[74] electronic intelligence (ELINT) gathering systems;[75] defensive systems for countering missile and airborne fighters;[76][77][78][79] and recorders for SLAR, ELINT, and maintenance data. We do not know whether they then went on to move across that bridge. Thankfully, this possibility seemed less and less likely, and the SR-71 was also capable of conventional intelligence gathering. However, the USAF refused to spend the money. [37] Cooling was carried out by cycling fuel behind the titanium surfaces in the chines. Kelly Johnson submitted his proposal for the U-2, essentially a glider with a jet engine and a panning camera in its belly. By the time the SAM site could track the SR-71, it was often too late to launch a SAM, and the SR-71 would be out of range before the SAM could catch up to it. SR-71 dual-seat reconnaissance aircraft operated by U.S. Air Force. The CIA ordered 12 of these aircraft, and starting in 1965, A-12s began flying missions as part of Operation Black Shield out of Kadena Air Force Base on Okinawa, Japan. The Lockheed SR-71 Blackbird was a two-seat twin-engine long-range supersonic strategic reconnaissance aircraft produced by Lockheed Corporation. Proper alignment was achieved as the airframe heated up, with thermal expansion of several inches. On 28 July 1976, SR-71 serial number 61-7962, piloted by then Captain Robert Helt, broke the world record: an "absolute altitude record" of 85,069 feet (25,929 m). Thirteen were built; two variants were also developed, including three of the YF-12 interceptor prototype, and two of the M-21 drone carrier.

SAS, autopilot, and manual control inputs would fight the yawing, but often the extreme off-angle would reduce airflow in the opposite engine and stimulate "sympathetic stalls". [69] As an aid to the pilot when refueling, the cockpit was fitted with a peripheral vision horizon display. 61-7959) in "big tail" configuration, 2728 July 1976: SR-71A sets speed and altitude records (altitude in horizontal flight: 85,068.997ft (25,929.030m) and speed over a straight course: 2,193.167 miles per hour (3,529.560km/h)), 15 January 1982: SR-71B, AF Ser. [104] The Skunk Works was able to return the aircraft to service under budget at $72million. American leaders needed to know about the Soviet Unions nuclear capability, ICBM program, and military installations. This flight was awarded the 1971 Mackay Trophy for the "most meritorious flight of the year" and the 1972 Harmon Trophy for "most outstanding international achievement in the art/science of aeronautics".[132]. The aircraft, which was at 20km altitude, quickly lost altitude and turned 180 to the left and turned over Gotland to search for the Swedish coast. SR-71s first arrived at the 9th SRW's Operating Location (OL-8) at Kadena Air Base, Okinawa, Japan on 8 March 1968. Two A-12s were modified to carry and launch the Lockheed D-21 remotely piloted reconnaissance drone, which would be powered by a Marquardt ramjet engine. Yesterday's historic transcontinental flight was a sad memorial to our short-sighted policy in strategic aerial reconnaissance.[136]. Lockheed Martin. As the fastest jet aircraft in the world, the SR-71 has an impressive collection of records and history of service. One successful offshoot of the A-12 was the SR-71 Blackbird. Landis and Jenkins 2005, pp. The SR-71 was designed for flight at over Mach3 with a flight crew of two in tandem cockpits, with the pilot in the forward cockpit and the reconnaissance systems officer operating the surveillance systems and equipment from the rear cockpit, and directing navigation on the mission flight path. Congressional conferees stated the "experience with the SR-71 serves as a reminder of the pitfalls of failing to keep existing systems up-to-date and capable in the hope of acquiring other capabilities. Instead, the SR-71's camera systems could be located either in the fuselage chines or the removable nose/chine section. More than a decade after their retirement the Blackbirds remain the world's fastest and highest-flying production aircraft ever built. The aircraft was meant to be powered by the Pratt & Whitney J58 engine, but development ran over schedule, and it was equipped instead with the less powerful Pratt & Whitney J75 initially. [118] Opponents estimated the aircraft's support cost at $400 to $700million per year, though the cost was actually closer to $300million. Hall also stated they were "looking at alternative means of doing [the job of the SR-71]. [25][26] The SR-71 was designed to minimize its radar cross-section, an early attempt at stealth design. Now when talking about SR-71 probably the most frequently asked Blackbird question is-how high and how fast does it really fly? The Blackbird was to retrace and photograph the flightpath of the hijacked 727 from Seattle to Reno and attempt to locate any of items that Cooper was known to have parachuted with from the aircraft. SR-71 Blackbird - Absolute Altitude (Sustained Flight) - Manned Aircraft. US Air Force supersonic aircraft, 19641998, "SR-71" redirects here. [104] In 1996, the USAF claimed that specific funding had not been authorized, and moved to ground the program. [42] Drawing on early studies in radar stealth technology, which indicated that a shape with flattened, tapering sides would reflect most energy away from a radar beam's place of origin, engineers added chines and canted the vertical control surfaces inward. [63], Originally, the Blackbird's J58 engines were started with the assistance of two Buick Wildcat V8 internal combustion engines, externally mounted on a vehicle referred to as an AG330 "start cart". Kelly Johnson realized that the A-12 airframe might work, and designed an interceptor version of the A-12. [138][139] However, the USAF is officially pursuing the Northrop Grumman RQ-180 UAV to assume the SR-71's strategic ISR role. The limitations of reconnaissance satellites, which take up to 24 hours to arrive in the proper orbit to photograph a particular target, make them slower to respond to demand than reconnaissance planes.
