A recollection of the Beginnings of the Hexagon Program By Art Weinstein

In early, 1964 the Corporate Controller (Tom Kindilien) formed the Project Accounting Group within the Electro-Optical Division and persuaded myself (Art Weinstein) to rejoin the Accounting Department from his stint at Project Administration at the Connecticut Avenue facility (which many of us will know was the originator of the Hexagon Program).

From the onset, the principal task was to submit a proposal (aka ”Special Project”) fora camera that would be housed within a satellite. The group was composed of a small group of engineers, tech writers, project administers and an accountant, who were tasked to write and price the proposal was located behind a locked door in 50 Danbury Road (later dubbed “The Wilton Hilton”). Just a small sample (not to slight any that I don’t remember) of the personnel responsible for writing the proposal were (Engineers: Dick Babish, Earle Browne, Bob Landsman , Project Administration: Bob Forsythe, Tom Doherty, Finance:  Ed Ronan, Art Weinstein , Technical Documentation & Writing: Bob Ogden, John Restivo).   

My fond memories of people like Charlie Karatzas, Dick Babish and Paul Petty will extend long after the announcement (in the fall of 1966) of $30 million award (for the newspapers) by Mike Maguire of a major government contract.  Needless to say that was one of instigators that caused P-E stock to catapult from the Thirties to the Eighties within a relatively short period and then many happy memories (follow the 20 missions (and unfortunately # 20 was sorrowful).  

 

 

Photos of PE Danbury in 1968 and 1982

Notice the differences between the two photos. The one taken on 2-19-68 was taken from plane and shows the original site when we all moved in it in 1968. You can barely see a car. The photo taken in 1982 was taken by Hexagon's mission 17 from over 100 miles up. You can see route 7 and to the left the Danbury airport. You can also notice that the building has grown greatly and to the right of the driveway you can see a white line that is the dam for the pond.

Decades Later, a Cold War Secret Is Revealed

Published December 25, 2011 Associated Press

DANBURY, Conn. –  For more than a decade they toiled in the strange, boxy-looking building on the hill above the municipal airport, the building with no windows (except in the cafeteria), the building filled with secrets.

They wore protective white jumpsuits, and had to walk through air-shower chambers before entering the sanitized "cleanroom" where the equipment was stored.

They spoke in code.

Few knew the true identity of "the customer" they met in a smoke-filled, wood-paneled conference room where the phone lines were scrambled. When they traveled, they sometimes used false names.

At one point in the 1970s there were more than 1,000 people in the Danbury area working on The Secret. And though they worked long hours under intense deadlines, sometimes missing family holidays and anniversaries, they could tell no one — not even their wives and children — what they did.

They were engineers, scientists, draftsmen and inventors — "real cloak-and-dagger guys," says Fred Marra, 78, with a hearty laugh.

He is sitting in the food court at the Danbury Fair mall, where a group of retired co-workers from the former Perkin-Elmer Corp. gather for a weekly coffee. Gray-haired now and hard of hearing, they have been meeting here for 18 years. They while away a few hours nattering about golf and politics, ailments and grandchildren. But until recently, they were forbidden to speak about the greatest achievement of their professional lives.

"Ah, Hexagon," Ed Newton says, gleefully exhaling the word that stills feels almost treasonous to utter in public.

It was dubbed "Big Bird" and it was considered the most successful space spy satellite program of the Cold War era. From 1971 to 1986 a total of 20 satellites were launched, each containing 60 miles of film and sophisticated cameras that orbited the earth snapping vast, panoramic photographs of the Soviet Union, China and other potential foes. The film was shot back through the earth's atmosphere in buckets that parachuted over the Pacific Ocean, where C-130 Air Force planes snagged them with grappling hooks.

The scale, ambition and sheer ingenuity of Hexagon KH-9 was breathtaking. The fact that 19 out of 20 launches were successful (the final mission blew up because the booster rockets failed) is astonishing.

So too is the human tale of the 45-year-old secret that many took to their graves.

Hexagon was declassified in September. Finally Marra, Newton and others can tell the world what they worked on all those years at "the office."

"My name is Al Gayhart and I built spy satellites for a living," announced the 64-year-old retired engineer to the stunned bartender in his local tavern as soon as he learned of the declassification. He proudly repeats the line any chance he gets.

"It was intensely demanding, thrilling and the greatest experience of my life," says Gayhart, who was hired straight from college and was one of the youngest members of the Hexagon "brotherhood".

He describes the white-hot excitement as teams pored over hand-drawings and worked on endless technical problems, using "slide-rules and advanced degrees" (there were no computers), knowing they were part of such a complicated space project. The intensity would increase as launch deadlines loomed and on the days when "the customer" — the CIA and later the Air Force — came for briefings. On at least one occasion, former President George H.W. Bush, who was then CIA director, flew into Danbury for a tour of the plant.

Though other companies were part of the project — Eastman Kodak made the film and Lockheed Corp. built the satellite — the cameras and optics systems were all made at Perkin-Elmer, then the biggest employer in Danbury.

"There were many days we arrived in the dark and left in the dark," says retired engineer Paul Brickmeier, 70.

He recalls the very first briefing on Hexagon after Perkin-Elmer was awarded the top secret contract in 1966. Looking around the room at his 30 or so colleagues, Brickmeier thought, "How on Earth is this going to be possible?"

One thing that made it possible was a hiring frenzy that attracted the attention of top engineers from around the Northeast. Perkin-Elmer also commissioned a new 270,000-square-foot building for Hexagon — the boxy one on the hill.

Waiting for clearance was a surreal experience as family members, neighbors and former employers were grilled by the FBI, and potential hires were questioned about everything from their gambling habits to their sexuality.

"They wanted to make sure we couldn't be bribed," Marra says.

Clearance could take up to a year. During that time, employees worked on relatively minor tasks in a building dubbed "the mushroom tank" — so named because everyone was in the dark about what they had actually been hired for.

Joseph Prusak, 76, spent six months in the tank. When he was finally briefed on Hexagon, Prusak, who had worked as an engineer on earlier civil space projects, wondered if he had made the biggest mistake of his life.

"I thought they were crazy," he says. "They envisaged a satellite that was 60-foot long and 30,000 pounds and supplying film at speeds of 200 inches per second. The precision and complexity blew my mind."

Several years later, after numerous successful launches, he was shown what Hexagon was capable of — an image of his own house in suburban Fairfield.

"This was light years before Google Earth," Prusak said. "And we could clearly see the pool in my backyard."

There had been earlier space spy satellites — Corona and Gambit. But neither had the resolution or sophistication of Hexagon, which took close-range pictures of Soviet missiles, submarine pens and air bases, even entire battalions on war exercises.

According to the National Reconnaissance Office, a single Hexagon frame covered a ground distance of 370 nautical miles, about the distance from Washington to Cincinnati. Early Hexagons averaged 124 days in space, but as the satellites became more sophisticated, later missions lasted twice as long.

"At the height of the Cold War, our ability to receive this kind of technical intelligence was incredible," says space historian Dwayne Day. "We needed to know what they were doing and where they were doing it, and in particular if they were preparing to invade Western Europe. Hexagon created a tremendous amount of stability because it meant American decision makers were not operating in the dark."

Among other successes, Hexagon is credited with providing crucial information for the Strategic Arms Limitation Talks between the United States and the Soviet Union in the 1970s.

From the outset, secrecy was a huge concern, especially in Danbury, where the intense activity of a relatively small company that had just been awarded a massive contract (the amount was not declassified) made it obvious that something big was going on. Inside the plant, it was impossible to disguise the gigantic vacuum thermal chamber where cameras were tested in extreme conditions that simulated space. There was also a "shake, rattle and roll room" to simulate conditions during launch.

"The question became, how do you hide an elephant?" a National Reconnaissance Office report stated at the time. It decided on a simple response: "What elephant?" Employees were told to ignore any questions from the media, and never confirm the slightest detail about what they worked on.

But it was impossible to conceal the launches at Vandenberg Air Force base in California, and aviation magazines made several references to "Big Bird." In 1975, a "60 Minutes" television piece on space reconnaissance described an "Alice in Wonderland" world, where American and Soviet intelligence officials knew of each other's "eyes in the sky" — and other nations did, too — but no one confirmed the programs or spoke about them publicly.

For employees at Perkin-Elmer, the vow of secrecy was considered a mark of honor.

"We were like the guys who worked on the first atom bomb," said Oscar Berendsohn, 87, who helped design the optics system. "It was more than a sworn oath. We had been entrusted with the security of the country. What greater trust is there?"

Even wives — who couldn't contact their husbands or know of their whereabouts when they were traveling — for the most part accepted the secrecy. They knew the jobs were highly classified. They knew not to ask questions.

"We were born into the World War II generation," says Linda Bronico, whose husband, Al, told her only that he was building test consoles and cables. "We all knew the slogan 'loose lips sink ships.'"

And Perkin-Elmer was considered a prized place to work, with good salaries and benefits, golf and softball leagues, lavish summer picnics (the company would hire an entire amusement park for employees and their families) and dazzling children's Christmas parties.

"We loved it," Marra says. "It was our life."

For Marra and his former co-workers, sharing that life and their long-held secret has unleashed a jumble of emotions, from pride to nostalgia to relief — and in some cases, grief.

The city's mayor, Mark Boughton, only discovered that his father had worked on Hexagon when he was invited to speak at an October reunion ceremony on the grounds of the former plant. His father, Donald Boughton, also a former mayor, was too ill to attend and died a few days later.

Boughton said for years he and his siblings would pester his father — a draftsman — about what he did. Eventually they realized that the topic was off limits.

"Learning about Hexagon makes me view him completely differently," Boughton says. "He was more than just my Dad with the hair-trigger temper and passionate opinions about everything. He was a Cold War warrior doing something incredibly important for our nation."

For Betty Osterweis the ceremony was bittersweet, too. Not only did she learn about the mystery of her late husband's professional life. She also learned about his final moments.

"All these years," she said, "I had wondered what exactly had happened" on that terrible day in 1987 when she received a phone call saying her 53-year-old husband, Henry Osterweis, a contract negotiator, had suffered a heart attack on the job. At the reunion she met former co-workers who could offer some comfort that the end had been quick.

Standing in the grounds of her late husband's workplace, listening to the tributes, her son and daughter and grandchildren by her side, Osterweis was overwhelmed by the enormity of it all — the sacrifice, the secrecy, the pride.

"To know that this was more than just a company selling widgets ... that he was negotiating contracts for our country's freedom and security," she said.

"What a secret. And what a legacy."

Top Secret

The following article about the Hexagon program was sent to me by Jon Aspinwall. It was published in 2011 right after the program was declassified by the NRO. Three facts  in the article are not correct. First of all it could not read a license plate. It's longuest mission was not 180 days. It was 275 days. Only 19 satellites, not 20 were sent in orbit. 

TOP SECRET: Your Briefing on the CIA's Cold-War Spy Satellite, 'Big Bird'

·    ALEXIS C. MADRIGAL - DEC 29, 2011

 The amazing story of how our supersecret, Cold-War spy satellites took photos of the Soviet empire and dropped them to Earth, all without the help of computers, bandwidth, or digital cameras.

Here's your mission, should you choose to accept it: build a camera that can take high-resolution photographs of the Earth from orbit and return them to the Central Intelligence Agency. There's only one catch: you don't get to use a computer or a single kilobyte of network bandwidth.

That's the task that the United States government gave to a group of engineers at the optical instruments company Perkin-Elmer in Danbury, Connecticut at the height of the Cold War. It was October 1966 and the new development of the new satellite system, Hexagon, was underway. The project was a follow-on to very successful Corona satellite program and a complement to the higher-resolution Gambit satellite. 

All these programs required 315,000 feet of film to be dropped in re-entry vehicles from orbit and retrieved in mid-air by U.S. forces. Gambit and Hexagon were declassified late this year, and its engineers were profiled this week by the Associated Press

Hexagon was known as "Big Bird" and up to 1,000 Perkin-Elmer employees worked on the program during its peak in the 1970s. Almost nothing was known about the program, except for scraps of information that leaked out to reporters. For example, in 1977, the AP reported, "At present, the United States has only one Big Bird reconnaissance satellite at a time in orbit. If the Big Bird were to be destroyed by surprise attack, it might be months before the Air Force could replace it." It was also known by the likes of William Safire that our satellites could "read the license plates on the cars of Kremlin officials." But what was known was mostly lore: "the American Big Bird... is said to be able to  photograph from 100 miles up people walking the streets of Moscow." 

In this case, though, the reality is more interesting than the legend. Our satellite programs were ridiculous collaborations between optical specialists like the Perkin-Elmer researchers, Lockheed Martin's satellite makers, Kodak's film creators, and the Air Force's pilots. Check out the AP's description of the program and note the many points of virtuosity.

All of this is now detailed in the National Reconnaissance Office's declassification reports about Hexagon, which include a 72-page overview produced in 1978 and marked TOP SECRET. I've pulled out some of the most fascinating diagrams from the Hexagon overview. For some reason, the hand-lettered proto-Powerpoint drives home to me how long ago we developed this satellite photo capability. We could take photos of Earth from space before we could do desktop publishing.

There are so many interesting things about Hexagon -- and our spy satellite program generally -- that it's hard to pick out what to highlight out of the hundreds of pages of history. Here are five things that stick out to me.

1. While Apollo may have stolen all the glory, the real humans-in-space success story is the satellite program. While we've never gone back to the moon, there are nearly 1,000 known satellites circling the Earth right now. Each Hexagon, of which there were 20, was nearly as big as NASA's Spacelab.

2. Some historians, at least, believe that spy satellites helped keep the Cold War cool. By providing planners with some information about what was going on behind the iron curtain, they kept the fever dreams of our decisionmakers in check. "At the height of the Cold War, our ability to receive this kind of technical intelligence was incredible," space historian Dwayne Day told the AP. "We needed to know what they were doing and where they were doing it, and in particular if they were preparing to invade Western Europe. Hexagon created a tremendous amount of stability because it meant American decision makers were not operating in the dark." 

3. The technical feat of creating a system to monitor the earth at 2-foot resolution without using computers' calculating power is stupendous. The Perkin-Elmer contractors did the math -- and the drawing -- by hand. The satellite also had almost no bandwidth. The images the system created had to be delivered back to earth by what must be the most elaborate sneakernet ever devised. The photographs were dropped back onto our planet in the Mark 8 reentry vehicle and then picked up by American ships.

4. Infighting between the CIA and the Department of Defense's National Reconnaissance Office nearly killed off the mission. It's fascinating to think that there were multiple competing satellite reconnaissance programs housed within the dark arms of the US government. The Cold War bred a ton of new technology out of the most byzantine bureaucracy. 

5. This was an exercise in preposterously complex sandcastle building. All the work went into satellites that were temporary. Early missions lasted 30 days; the longest lasted 180 days. They made what they did knowing the earth's atmosphere would burn it up, leaving nothing behind but classified photographs and some old men with great stories at the Danbury Mall food court. 

"My name is Al Gayhart and I built spy satellites for a living," one engineer says. 

Now we know how.

 

How the US Built Its Super-Secret Spy Satellite Program

Pentagon.jpg

Andrew Tarantola

Ethics aside, espionage is an indispensable part of statecraft. The ISR [Intelligence, Surveillance, and Reconnaissance] information gathered helps steer national policy decisions for everything from mundane trade negotiations to the blackest of ops. And nowhere is this more evident than in the development of the US spy satellite fleet during the Cold War. These orbital telescopes granted an unprecedented peek over the Iron Curtain—revealing Soviet military capabilities, supply reserves, industrial sites, and more—that no ground-based spook could hope to provide.

During the Cold War, accurately ascertaining the USSR's military capabilities was a top US priority—as well it should have been given that we had as many as 21,000 nuclear warheads pointed at each other during that time. And while we had plenty of spies operating in Moscow, the view from overhead provided the President and his cabinet key insights into the extent of Soviet strategic capabilities which influenced defense planning and arms control negotiations. As such, the US invested vast sums of money into high-altitude research—from early "weather balloons" to the SR-71 Blackbird and U2 Dragon Lady to orbital telescopes—and established not one but three Federal agencies—the National Reconnaissance Office (NRO), the National Security Agency (NSA), and the Central Intelligence Agency (CIA)—all in an effort to glean any speck of information that could give us an advantage.

Satellite technology is, by far, the most expensive ISR method at the US's disposal but also the most effective, its results well worth the billions of dollars spent. As President Lyndon B. Johnson famously quipped in 1967 after a Soviet hoax led to worries of a bomber gap:

I wouldn't want to be quoted on this ... We've spent $35 or $40 billion on the space program. And if nothing else had come out of it except the knowledge that we gained from space photography, it would be worth ten times what the whole program has cost. Because tonight we know how many missiles the enemy has and, it turned out, our guesses were way off. We were doing things we didn't need to do. We were building things we didn't need to build. We were harboring fears we didn't need to harbor.

Of course, much of the development of our national reconnaissance capabilities is still shrouded in veils of classification. Heck, the NRO was established in 1961 and operated for three decades before the government even ever acknowledged its existence. Press reports made limited references to the agency as far back as 1971, but it wasn't until the Deputy Secretary of Defense revealed the NRO in 1992, was it ever formally discussed by the DoD. Oversight from the DoD and Congress was virtually non-existent save for the "open-checkbook" policy of the times. As long as the intelligence justified the price tag, any cost was acceptable. It wasn't until the early 1990's that any information on these devices was declassified, after the fall of the Soviet Union brought an end to the Cold War. Even now, information on the early satellites is sparse and anything after 1972 is non-existent save for a few photos taken by the KH-11 satellite which were leaked to Jane's Defence Weekly in 1985.

What we do know is that the US has been researching high-altitude reconnaissance technology since about 1946 when the RAND project, precursor to Rand Corp., began campaigning for its development. When the Army and Navy couldn't agree on who would have control over the orbital technology, it was assigned to the newly-formed USAF in 1947. It took a few years for RAND researchers working on "Project Feedback" to figure out how a satellite would even function—this was a brand new technological concept, mind you—but by 1953 they had not only devised the general characteristics and capabilities of a reconnaissance satellite but had begun to develop many of the components as well, like the television system and altimeter. The Atomic Energy Commission also began work on miniaturized nuclear power sources for the vehicles at that time. By 1954, the USAF accepted RAND's assertion that the technology was of "vital strategic interest to the United States" and officially established the US satellite program.

The Corona Program

The first such program was the Corona project, a codeword itself code named "Discoverer" for the public explanation of why the government was firing a rocket into space (a rare event in the late 1950s that would have attracted a curious public and international scrutiny). The program began in 1959 at the Onizuka Air Force Station, ran until 1972, and was declassified in 1995 by President Clinton. Its initial budget was a modest $108.2 million ($860 million adjusted to 2013), though that quickly increased following the 1960 incident in which Gary Powers' U2 was shot down over Soviet airspace. The 144-member family of Corona satellites—each designated Keyhole-#, or KH-#, depending on the spacecraft iteration—were produced and operated by the CIA in conjunction with the USAF and provided invaluable photographic surveillance of the Soviet Union as well as the People's Republic of China, and other Communist countries.

Launched aboard a Thor booster rocket and Agena spacecraft, these satellites relied on a pair of five foot long stereoscopic Itek cameras using 12-inch, f/5 triplet lenses and a 24-inch focal length (later models also incorporated a third "index" camera for reference). The early cameras could achieve a 40-foot resolution. By KH-3, optical improvements decreased that figure to 20 feet. Later missions continued to halve the resolution until researchers were able to resolve one-foot wide objects, realized that that was way too close to be of any strategic use and backed off to a more manageable 3-foot resolution.

They were fed a special Eastman Kodak 70 millimeter film that produced 170 lines per mm—more than three times the 50 lines/mm resolution earlier WWII aerial photography could compose. The first Coronas carried a paltry 8,000 feet of film—per camera—though through improvements in the film chemistry and design reduced the material thickness, researchers were eventually able to double that amount. The cameras themselves underwent numerous upgrades as well, elongating to nine feet and incorporating panoramic Petzval f/3.5 lenses.

Once the camera had run through its full complement of film, it would eject the roll via a reentry capsule designed by General Electric. After the capsule discarded its heat shield at 60,000 feet, it deployed a parachute and could either be nabbed by a passing plane equipped with a claw hook (above) or land safely in the ocean where it would float for two days awaiting pickup. If the capsule wasn't retrieved within 48 hours, a salt plug at the bottom of the canister would dissolve and sink it. If it was picked up in time, the film would be transported to Rochester, New York, for processing at Eastman Kodak's Hawkeye facility.

The Argon Program

The KH-5 ARGON ran in conjunction with Corona from 1961 to 1964, though never with the same degree of success. These 1150 - 1500 kg satellites manufactured by Lockheed Martin and operated by the NR used a single 76 mm focal length camera with a 140 meter resolution were operated primarily for map-making—they were the first to image Antarctica from space—and took less than a week to produce. Of the 12 flights attempted, however, only five successfully put the unit in orbit.

The Lanyard Program

The KH-6 Lanyard program was the NRO's first attempt at high definition photography but lasted just six months and three launches in 1963, two of which failed to produce images. These 1500 kg Lockheed satellites were hastily constructed using the previously-cancelled Itek "E-5" camera in order to survey a rumored anti-ballistic missile site near Tallinn, Estonia. The E-5 had a 66-inch focal length and six foot resolution covering a 9 x 46 mile area. The only successful flight returned 910 photographic frames. However, the image quality was so poor that they were virtually useless.

The Gambit Program

Outside of the Corona program, America's initial attempts at satellite photo-reconnaissance failed more often than not. The KH-7 and KH-8 series, codenamed Gambit, were a marked departure from that trend and the only other predominantly successful satellite ISR program in the 1960s. This 3,000 kg Low Altitude Surveillance Platform developed by Lockheed flew just 75 miles up (Coronas orbited at 100 miles) and operated for nearly two decades from 1964 to 1984. No fewer than 54 such satellites launched (these things only worked for three months, tops) from Vandenberg AFB aboard Titan III rockets during that time.

Eastman Kodak's A&O Division in Rochester, New York, produced the Gambit's primary strip camera system. With a focal length of 175.6 inches, a 6.3 km wide coverage area, and 3-foot resolution, the KH-8 was ideal for gathering high-resolution images of Soviet sites. Unlike conventional aperture cameras, the Gambit's slit camera reflected light off of a 48-inch mirror, through a slit aperture, and on to a moving length of Eastman Kodak Type 3404 film. It would then either drop the roll as the Coronas did or automatically develop the photographs, scan them, and transmit the images back to Earth in as little as 20 minutes through the Film Read-Out GAMBIT (FROG) feature (though after $2 billion dollars and nearly a decade of development the 1971 administration nix(on)ed it).

In addition to keeping tabs on Soviet air capabilities, Gambit was also designed to photograph the spacecraft around it. This ability came in handy in 1973. The brand new Skylab had just launched when its meteoroid shield broke loose and damaged the space station. As NASA scrambled to send up a manned repair mission, the NRO launched a new Gambit, which snapped this picture and helped NASA engineers plan accordingly.

The HEXAGON Program

The KH-9 HEXAGON was, by all accounts, an unmitigated success with 19 of its 20 launches reaching orbit between 1971 and 1986. This $3.262 billion Lockheed-built NRO program is officially deemed a Broad Coverage Photo Reconnaissance satellite but is better known as "Big Bird." And while its existence wasn't revealed until 2011, the program dates back to the 1960s as a successor to the Corona program.

The first generation of HEXAGON employed a pair of f/3.0 folded Wright Camera cameras with a 60-inch focal length able to resolve objects down to 2 feet and carried four re-entry vehicles. The last three generations featured a pair of panoramic cameras as well as upgraded electronics, C&C systems and nitrogen-supplied re-entry canisters. They also a began surviving longer. Most spy satellites have very limited life spans—two to three months—and once they're out of film they have no further purpose. But with ever increasing film payloads, the final iteration of the KH-9 lasted 275 days in space. Between 1973 and 1980, these satellites imaged every square foot of the Earth in 29,000 pictures, much of it better quality than LANDSAT, a rival satellite mapping program. Most of these images have been declassified since 2002, though sensitive areas such as government installations and most of Israel remain tightly guarded.

The KENNAN Program

The KH-11 KENNAN is the most advanced recon satellite to be unclassified. First launched in 1976 by the NRO, it's the first US satellite to employ an EO digital sensor and charge-coupled device (CCD), which reportedly provides an Enemy of the State-style real-time observation capability. Very little is known about the satellite's hardware though many have speculated that its roughly the same size as the Hubble Space Telescope with a similar 2.4-meter mirror producing a six inch resolution. There's also wide speculation that the KH-11 is the source of images declassified in the wake of the 1998 embassy bombings, as well as others of China and Russia declassified the year prior. The images the CIA used to find Osama bin Laden's hideout were reportedly supplied by the KENNAN. Fifteen KH-11's have been launched in total—nine between 1976 and 1990 aboard Titan-3D rockets, five between 1992 and 2005 aboard Titan IVs, and the final one in 2011 aboard a Delta IV—at an estimated cost of $2.2 to 3 billion.

The end of the Cold War certainly put a damper on reconnaissance satellite funding, as did the rise of commercial satellite technology, but it remains a staple of our intelligence gathering resources. The technology has also found new use in providing tactical information to ground troops (not having to catch film canisters with sky hooks helps). Satellite imagery was first used in 1991 during Desert Shield and again in Iraq, Bosnia, Kosovo, and Afghanistan.
