The U-2 provided critical intelligence before the evolution of spy satellites.

In times of war, much is made of the “high ground” advantage. There’s no denying that this is highly relevant to ground forces, and as such, it is a primary factor in assessing the viability of an observation position. In these circumstances, this might refer to a mountain in country terrain, while in the city or urban surroundings, it might refer to a building or other elevated position.

It’s fair to say, though, that the “high ground” theory differs dramatically once you enter the world of the Air Force. And there is no higher ground than that achieved by a surveillance or reconnaissance platform.

We’ve talked about Lockheed’s SR-71A and covered how it used raw speed for protection. Before the SR-71A, though, there was an aircraft known as the “Dragon Lady,” and it worked on an entirely different concept in comparison to the SR-71. Here, altitude was life, but it would take some smart flying and plenty of ground support to ensure these missions could be completed successfully.

Still in use today, the U-2 Dragon Lady has an esteemed past and, like the Blackbird, it’s been involved in plenty of Geopolitical incidents over the years. This means it has LOTS of interesting history to discuss.

The Beginnings

Like the Blackbird, the U-2A would be born in the aftermath of World War 2, before satellites and computers would reshape the world entirely.

While the world would be focused on rocketry in the aftermath of the war, it’s fair to say that much of the technology we see as commonplace today either hadn’t been invented yet or was in its infancy.

This would have a lasting effect on the design ethos of many aircraft platforms and would be partly responsible for the savage performance of many Cold War era Century Series aircraft.

For many fighter pilots, speed was life, and this attitude permeated into the tactics and theory of most fighter pilots of the day. This was the era of true airpower, a time when raw performance and thrust would be unmatched by pesky things like surface-to-air missile systems or fighter interceptors.

As such, people who thought out of the box had plenty to offer the school of aviation, and in the 50’s and 60’s, no one thought out of the box quite like Lockheed’s Clarence “Kelly” Johnston.

The Concept

This out-of-the-box thinking would lead to some rather interesting aircraft designs, but it would be the U-2 that helped establish the legacy of Johnson as one of the world's premier aircraft designers.

While many designers of the time focused on the new performance offered by the still-new turbofan engine, Johnson would be one of the first to recognise that a huge lifting surface paired with a high-thrust turbofan engine would offer a significant performance boost in comparison to the more modern frontline fighters of the day.

Using little more than a slide rule and some experience, Johnson would progress extremely quickly on the new design and, while the new design would be revolutionary, it wouldn’t be without its problems.

The focus on weight meant that while the U-2 had plenty of performance, it didn’t actually have a huge amount to spare. The high-aspect wings paired with the aircraft’s speed and weight configurations meant that for most of the flight, it would be extremely close to “coffin corner”.

Here, stall speed would meet cruising speed, and while the U-2’s performance remains mostly classified even today, the one thing we did know was that the cruise speed would be mere knots over the stall speed.

This meant that pilots flying the U-2 would have much of their time taken up by correctly piloting the aircraft while working the cameras, making the Dragon Lady a high-workload aircraft in the cruise.

Active Service

One of the most unique aspects of the U-2 would be its rapid design phase, which would end up putting the aircraft into service pretty quickly. There’s no arguing that here, Johnson saw an opening to exploit, and a rapid introduction would be a key part of exploiting this weakness fully.

In the early days, height was considered to be as good as stealth with regard to concealing both pilot and aircraft from enemy eyes, but unfortunately, it didn’t take long for the theory to play out as incorrect.

On one of the aircraft’s first flights over the Soviet Union, protests were lodged, as while the Soviets couldn’t get to the altitude of the U-2, they most certainly could see it on Radar.

This would cause moderate concern in Washington as it didn’t take long to deduce that “seeing” the aircraft was mere steps away from “attacking the aircraft”, and as such, caution was taken when operating the platform over the soviet union.

Unfortunately, this caution wouldn’t be enough by the time 1960 came around.

Around this time, US Air Force pilot Gary (Francis) Powers would be prepped for a mission to overfly the Soviet Union in search of fresh intelligence regarding the Soviet missile and submarine program. Known as operation “Grand Slam”, it would offer the prospect of filling in many of the blanks that focused on the Soviet Programs of the era.

Unfortunately for Powers, it was not yet known that the introduction of the S-75 Dvina missile (NATO: SA-2 Guideline) would pose a direct threat to the platform and Powers in general.
The Americans, who had gotten away with over 24 unannounced flights over Soviet territory, would be in for a rude shock this time around.

The S-75 Dvina (SA-2) Missile

Quietly introduced in 1957 to little fanfare, the S-75 Dvina would be hugely influential on modern warfare strategies. At the time of its launch, though, little was known regarding just how influential this system would be.

With an ability to reach a flight altitude of over 80,000ft while carrying a warhead of nearly 200kg, the Guideline posed a very real and present threat to the U-2 and its pilot.

While intelligence was aware of these developments, a lack of understanding of high-altitude flight meant that the Americans would fail to properly understand the risk factors and how they might influence the U-2 operations.

For instance, it was believed that despite being fitted with an ejection seat, an incident involving the U-2 would be unsurvivable, meaning that the chances of recovering a pilot would be little to none.

It was also believed that the thin air that existed above 70,000 ft in altitude would also protect the aircraft. Unfortunately, both of these predictions turned out to be very, very wrong. In May 1960, these factors would come to a head after the U-2 (56–6693) piloted by Powers would be lost over the Soviet Union.

With a NASA cover story in place, news of the shootdown meant that the US Air Force felt confident its cover story would hold. With no news about Powers in the official Soviet release, in the early days, the USAF thought it had got away with it.

Unfortunately, some wily tactics by soviet leader Nikita Kruschev meant that the Americans would later come to regret this play. Nearly three months later, after incriminating themselves multiple times, the ruse was up, and Khruschev would reveal that not only was Powers still alive, but the U-2’s airframe had been captured nearly entirely complete. Whoops.

Modern Operations

With the Blackbird long since retired, it might surprise some of you to realise that the U-2 remains in service playing a key role, even today.

In fact, the aircraft would last come into the limelight just two years ago in 2023. With unknown spy balloons operating over the continental United States, the U-2 would be one of the only aircraft that had the performance to safely operate at the altitudes needed to get a visual look and perform an interception of the balloon.

While it would be the much more glamorous F-22A Raptor that would be responsible for taking care of business regarding the shootdown, it would be the elderly U-2 platform that would be responsible for giving the USAF the first look at bogies in the American sky for some time.

Beyond this, the National Aeronautics & Space Administration would operate a small fleet of U-2 variants known as the ER-2. These aircraft would operate under the NASA livery and would provide real-time measurements to help with meteorology.

Fast jets have a reputation for having high performance and being a glamorous platform to fly. And, while this isn’t likely to change any time soon, the long and distinguished career of aircraft like the Dragon Lady means that often, the star of the show is the workhorse jet that gets results.

With a career spanning more than 5 decades, the U-2 is definitely one of those workhorse jets.
