Blackbird History

Lockheed's SR-71 Blackbird was ahead of its time. The history of the SR-71 can be traced back to 1957, the year that Lockheed's Advanced Development Project (better known as "Skunk Works") began exploring the feasibility of a higher-flying, faster, and less radar-visible alternative to the U-2. "Skunk Works" was originally called "Skonk Works," which was the name of a secret moonshine distillery in Al Capp's "Li'l Abner" comic strip. The name was changed slightly after Mr. Capp's editor threatened legal action for copyright infringement.

The SR-71 was designed without the aid of modern computers, but rather using slide rules and the "primitive" drafting techniques of the time. Its planning and construction were undertaken in total secrecy. The Blackbird program began as a project called "Archangel" eventually resulting in the single-seat A-11 (which evolved into the more stealthy A-12, code named OXCART) flown by civilian CIA pilots, an interceptor version called the YF-12A, and finally the two-seat SR-71 (code named SENIOR CROWN) flown by the U.S. Air Force. "SR" referred to its planned role as a strike/reconnaissance aircraft. The aircraft was originally designated the RS-71, but the letters were reversed after President Lyndon B. Johnson's now-infamous flub when he misread the name while announcing the program's existence to the world during a press conference on 24 July 1964.

The first flight of the SR-71 was on 22 December 1964, with Lockheed test pilot Bob Gilliland in the driver's seat. Now, at the outset of the 21st century, the Blackbird is still the most unique, fastest, highest-flying "air-breathing" aircraft in the world. The Blackbird, or "habu" as it is known by Air Force insiders, is capable of sustained speeds in excess of Mach 3 and has an altitude ceiling of over 80,000 feet. It was the first generation of "stealth" aircraft, utilizing Radar Absorbing Material to give it a radar cross-section of less than ten square meters.

A Record-shattering Aircraft

Below are just a few official blackbird records. As impressive as these are, the habu is unofficially rumored to have flown higher and faster! For example, in his book "Conquer the Sky" (Metro Books, 1996), Harold Rabinowitz states:
    "The SR-71 began its life as theYF-12, a high-speed interceptor fighter--fromcertain angles, in fact, an SR-71 looks to betwo aircraft melded together down the middle.The plane has been modified and improved manytimes since its introduction in 1964--newmaterials, new systems, and most importantly,new fuels have allowed the aircraft to reach itspotential speed of Mach 7-plus. However, theworld's airplane speed record is held by WilliamJ. "Pete" Knight, who flew an X-15-2A overEdwards Air Force Base at 4,535 miles per hour(7,297 kph), or Mach 6.72--a record set onOctober 3, 1967. Aviation observers point outthat several U.S. military aircraft (even somelater models of the SR-71) may be capable ofgreater speeds and that the USAF may well haveestablished new records in secret since."

For another viewpoint on just how high and how fast the Blackbird can go, consider the following, from John Stone's "Blackbird Myth & Fact":

THE ROLE OF THE SR-71 IN THE USS PUEBLO INCIDENT
North Korea: January 23, 1968. The USS Pueblo had just been captured off the North Korean coast. Decisions needed to be made quickly, and immediate intelligence was critical.

An SR-71 was launched from Kadena Air Base on the island of Okinawa (then a U.S. Protectorate, returned to Japan on May 15, 1972). In less than 25 minutes' time, the SR had reached North Korea, made its first run up the coastline, gathered its intelligence, turned around completely, and was on its way back in a southbound heading.

(Note distance scale at bottom of map)

Sadly, it was already too late--but not because of the Blackbird. The delay in deciding to launch the SR-71 was the reason the Pueblo was not found until it was in the posession of the North Koreans, and well out of our reach.

A source, serving at Kadena at the time, stated that he knew the SR-71 to exceed 100,000 feet in altitude and airspeeds in excess of 3,200 mph. He cited reports suggesting a ceiling of 120,000 feet and a top speed of more than 4,100 mph above 80,000 feet, but could not confirm the latter figures firsthand. He also noted, "these were the early birds, not the later, revised editions."

Farewell to the Blackbird?

This page is my tribute to these sleek, black planes and their pilots and crews. As of 1998, the habu is no longer on active military duty, having been offered up by U.S. Air Force top brass to President Clinton's line item veto, effectively "re-retiring" the aircraft. As of July 1999, four Blackbirds (original Air Force serial numbers < a href="http://www.habu.org/sr-71/17956.html">17956, 17967, 17971, and 17980 are now being flown by NASA's Dryden Flight Research Center. Serial numbers 17956 and 17980 were given tail numbers 831 and 844 by NASA. All four planes are being used for high-speed, high-altitude research.

The SR-71 is unparalleled in its ability to make high-speed passes over sensitive, high-threat areas. It can photograph, in great detail, 100,000 square miles of terrain in an hour. The Blackbird's cameras are said to be able to resolve an object the size of a golf ball from an altitude of more than 80,000 feet. Its speed makes it superior to the U-2 when surface-to-air or air-to-air missiles are a threat; its unpredictability makes it superior to satellite reconnaissance when sensitive intelligence of enemy territory is required. According to Clarence L. "Kelly" Johnson, former head of Skunk Works, over 1000 enemy SAMs (surface-to-air missiles) were fired at the SR-71. Not a single one hit its target.

"The SR-71 provides coverage on demand with little or no warning to the reconnaissance target--it is a highly flexible system... the SR-71 is able to penetrate hostile territory with comparatively little vulnerability to attack unlike other reconnaissance platforms."
--Senator John Glenn, 7 March 1990

Unfortunately, a campaign of misinformation mounted by the U.S. Air Force and the Federal Government has put the final nail in the coffin of the SR-71 program. Perhaps the low profile of the program has worked against it, as many government and military officials who worked so hard to kill the program didn't even know what the SR-71 did!

"The sad thing is this country will never know what it lost. We know the SR-71 is needed--now more than ever. In the last year alone there have been several unresolved crises that could have been satisfied with the Blackbird. You are all aware of them. How many more will follow in this ever-increasingly volatile world? The criminal thing is how many wrong decisions will be made, unnecessary piles of money spent, or American lives lost without the best intelligence at hand?"
--Leland Haynes, USAF Master Sergeant (ret), former SR-71 crew chief, 17 October 1998
