Who would win a battle in the skies, a Dragon Lady or a Blackbird? These are the nicknames of two high-altitude reconnaissance aircraft used by the United States Air Force (USAF) and the National Aeronautics and Space Administration (NASA).

The U-2: The Dragon Lady

The U-2 is an American high-altitude reconnaissance aircraft built by the Lockheed Corporation for the USAF and NASA, starting in the early 1950s. At this time, the United States was concerned that the Soviet Union would be able to achieve its long-term objectives, necessitating a new and improved aircraft.

The National Museum of the United States Air Force notes that "Lockheed's secretive 'Skunk Works' plant in California, under the direction of designer Kelly Johnson, proposed a new jet called the Model CL-282. The design had very long, high-efficiency wings and was lightweight enough to carry heavy cameras to altitudes over 70,000 feet, or about 13 miles." The museum also mentioned that the CIA accepted Lockheed’s design and used "Aquatone" as its codename.

On July 17th, 1956, Herbert I. Miller wrote a memorandum to the CIA project director suggesting that the elevated level of intelligence value from the U-2 program could benefit the United States. He stated: “In this light, the danger to our international relations appears to be far greater if we do not carry out the AQUATONE plan than if we do carry it out.”

Over time, various types of Pratt & Whitney jet engines powered the U-2 until General Electric's F188-101 engine became standard. Advancements led to models such as U-2R and TU-2U for training and tactical reconnaissance. Currently upgraded with significant investments including $1.7 billion for adding General Electric’s F188-101 engine, these models are classified as "S."

Additionally, NASA operates two Airborne Science ER-2 aircraft for satellite verification and other science-related missions. NASA has reported that “since Aug. 31, 1971, NASA U-2s and ER-2s have flown more than 4,500 data missions and test flights in support of scientific research.”

The SR-71 Blackbird

In 1966, Lockheed Corporation introduced another reconnaissance aircraft—the SR-71 “Blackbird.” This aircraft served both USAF and NASA until their retirements in January1990 due to decreasing defense budgets and high operational costs.

Developed from Lockheed A-12's black project—a covert military undertaking—the SR-71 acquired its name due to its unique black paint formulated to absorb radar signals while radiating airframe heat generated by air friction at high altitudes.

"The Blackbirds were designed to cruise at Mach3.2," noted NASA,“just over three times speed of sound or more than2200miles per hour at altitudes up85 thousandfeet.” With speeds reaching Mach3.2(2190mph),theSR71 remains one highest fastest aircraft ever built.

Technical Notes

Speed Mach3 .22+(2200+ mph3530+kph)@80k ft(24000 m)

Combat Range290nmi(540 km),

Ferry Range320nmii(592km),

Service ceiling11 ,810ft/min60m/s,

Payload350lbsensors160kg),

Both reconnaissance aircraft represent some best technology,pilots,and stealth capabilities,making them formidable forces within skies despite differing service statuses today.
