U-2 Spy Plane
The U-2 is a single-pilot, single engine, high altitude reconnaissance aircraft. It is the first plane to be built primarily for recon missions. The U-2 has long, straight, wide wings which gives it a glider like looks. It can carry a variety of different sensors and cameras. The U-2 is also a very reliable aircraft, and because of this enjoys a high mission completion ratio. Because of it's unusual landing characteristics is a very difficult airplane to master. Because of the altitude the U-2 flies at it is necessary for a pilot to were a full pressure suit.
The U-2 was built to a CIA request issued in 1954, for a high altitude spy plane. Designed and built at Lockheed's famous Advanced Development Projects or Skunk Works. The U-2 first took to the air on the first of August 1955. The initial testing site was called Paradise Ranch (even though it is located out in the Nevada desert).
The U-2 began flying spy-missions in 1956. These missions were top secret until May 1, 1960 when Gary Powers was shot down over Russian soil. He crashed and was captured, he was then tried and sentenced to ten years in jail. After this incident over-flights of Russia were permanently canceled.
Other over-flights and missions went on though and now the U-2 provides continuous day or night, high altitude, all-weather, stand of surveillance of a battle area or hostile area. It provides critical intelligence to generals and others throughout a conflict. On request the U-2 has also taken pictures for the Federal Emergency Management Agency after a disaster for damage reports.
The U-2's are based at Beale Air Force Base in California. These U-2's support four bases through out the world with tactical requirements. The new U-2 crews are also trained here in U-2ST trainers
Camera Systems Used By the U-2
HR-329 (H-cam) - The H-cam uses a high resolution, gyro-stabilizing framing system, with a 66 inch focal length and folded optical path. Most of the time the H-cam operates at an angle which allows it to cover more ground. During Desert Storm commanders played with the camera facing straight down, and they were impressed with the clarity and detail. However the downside was with the camera faced down the area covered was less, so it was a question of Quantity over Quality or vise-versa. Although the camera is great for identifying targets and determining battle damage, the film cannot be viewed until after the airplane lands.
Intelligence Reconnaissance Imagery System III (IRIS III) The IRIS 3 system is an optical imagery system that uses a high resolution, panoramic camera with a 24 inch focal length. Using a rotating optical bar the camera can scan 140 degrees of the total 180 degrees of viewing area. Even though the IRIS can make 32 nautical mile swipes of the land, and has a wider synoptic coverage than the H-cam it does not have the resolution of the H-cam.

U-2 Flight History
|1963||1||During the early
years of the U-2 program, the aircraft had mishaps. All of these mishaps
were investigated, but the reports were limited in number. None were
released to the general Air Force community nor were they put into the
Safety Center's data base. Also, the flight hours accumulated per year
were a closely guarded secret, so the ability to get an accurate mishap
rate was very difficult.
However, since the U-2 program has been largely declassified, this information is now available. The information provided in this chart is accurate, but the early years should be viewed with a wary eye. This chart represents all of the mishaps the Air Force Safety Center is aware of and all of the flying time flown by the U-2 since 1963. For the years FY63 to FY69, there is no accurate information on flying hours for the U-2 aircraft.
The U-2 aircraft was designed and fielded during the height of the Cold War, and this aircraft was one of the most secret US weapon systems. Also, the U-2 was designed in the 1950s ago when there wasn't any computer-aided design, system safety was just a dream, and the technology was on the outer limits of the aircraft industry.
However, the U-2 has performed outstandingly against all these odds and has been called upon when the nation needed valuable information on various hot spots in the world. So the mishap rate may be higher compared to newer aircraft (F-15 and F-16) or against aircraft of the same era (B-52 or C-130). But these aircraft have gone through many, many changes during the years of their operation.
In the early 1990s the mishap rates were relatively high. However, there was no one main reason for the increase in the mishap rate. This fact made the management of the U-2 program difficult at best. The aircraft is being upgraded with a new engine and other components, but as the Air Force Chief of Staff has indicated, this weapon system is in the sunset of its career.
