The Lockheed U-2

Since its inception the Lockheed (today Lockheed Martin) U-2 has played a vital role in American strategic intelligence. The unique high-flying reconnaissance jet was designed early in the Cold War to overfly and photograph military activities in the Soviet Union and other communist nations. The U-2, nicknamed “Dragon Lady” after a comic strip character of the 1930s, has been used by the US Air Force, the Central Intelligence Agency and the National Aeronautics and Space Administration.

However, as told by Krzysztof Dabrowsky in his book Hunt for the U-2 Interceptions of Lockheed U-2 Reconnaissance aircraft over USSR, Cuba and People’s Republic of China, 1959-1968, whoever might think that the U-2 was deployed to fly reconnaissance missions over the USSR, People’s Republic of China (PRC) or their allies only, is deadly wrong. Indeed, the jet is known to have seen ‘action over several ‘allied’ nations, just like its predecessor, the RB-57.

In July 1963, a pair of the then brand-new Dassault Mirage IIICJ interceptors is known to have intercepted an RB-57A of the USAF and forced it to land at Lod International Airport, in Israel.

The high-flying reconnaissance aircraft was underway from Saudi Arabia to Turkey and involved in monitoring the construction of the Israeli nuclear complex in Dimona.

Mirage III equipped with rocket booster to intercept an U-2

In June 1967 – a year after French President Charles de Gaulle withdrew his country from NATO – early warning radars of the French Air Force detected a U-2 underway in the direction of one of the country’s nuclear facilities.

A Mirage IIIE of the 2nd Fighter Wing (2ème Escadre de Chasse) was promptly scrambled from Dijon Air Base, with the task of intercepting the intruder.

Equipped with the SEPR 841 rocket booster, the interceptor literally soared into the skies, though not with the aim of actually shooting down the US aircraft – but to photograph it: photographs were of crucial importance for enabling Paris to provide evidence for a violation of its airspace in the case of the US denial.

French Mirage III nearly colliding with the U-2

After climbing to an altitude of 45,000ft (13,716m), the French pilot engaged his SEPR booster, which accelerated his Mirage to Mach 1.8, and enabled it to reach an altitude of 65,000ft (19,812m). While slightly decelerating to Mach 1.7, the French pilot caught with the U-2 as this was underway at Mach 0.9 and almost directly above Dijon AB.

Although wearing the bulky and uncomfortable high-altitude suit, he managed to take a photograph with an ‘average civilian camera,’ before nearly colliding with his ‘target’ while keeping it centred in his camera’s optical visor. Critically short on fuel after such a high-speed climb, the Mirage pilot then switched off the booster and glided back to base.

U-2 pilot shocked

While it is certain that the US pilot was warned about being intercepted, because all of the U-2s were equipped with advanced ECM-systems, it flew no evasion manoeuvres.

French sources think that the U-2 pilot was quite shocked by what happened next – first by the supersonic shock wave of the French interceptor, and then the Mirage flashing by underneath his nose.

What is certain is that the US subsequently stopped all overflights of France and would not return until years later – and then with Mach 3-capable Lockheed SR-71As at an altitude of 75,000 ft (22,860m)!

    Not to nit pick the article but let’s not assume the U2 was anywhere near Mach 0.9 at anywhere in its planned route. Mach 0.7 was closer to its designed cruise speed and any more would be catastrophic to the airframe.

    Imagine if they had tried that over Britain. No rockets required. An RAF Lightning would have just flown right up and said hello.
