developed for use during the International Geophysical Year <strong>of</strong> 1957/1958. This French sounding rocket<br />

was used from March 1959 until February 1969 <strong>and</strong> reached an apogee <strong>of</strong> 220 km. A further-improved<br />

version <strong>of</strong> Veronique, the 61M, was launched from June 1964 until 1970, fi rst from Hammaguir <strong>and</strong> then<br />

from Kourou. By 1958, Veronique had been replaced by the Pierres précieuses family <strong>of</strong> rockets from the<br />

company Sereb, which included the Agate, Rubis, Topaze, Saphir, Emeraude, <strong>and</strong> fi nally the Diamant. In<br />

1970, Sereb merged with Nord-Aviation <strong>and</strong> Sud-Aviation <strong>to</strong> become Aérospatiale.<br />

Besides the LRBA in Vernon, the French military authorities created an aerodynamics design <strong>of</strong>fi ce in the<br />

city <strong>of</strong> Emmendingen in southwest Germany, for which a large number (more than 30) <strong>of</strong> Peenemünde<br />

experts were hired. One <strong>of</strong> them was a key individual <strong>of</strong> the highest technical reputation in this fi eld, Helmut<br />

Weiss, who had worked immediately after the War for the British Ministry <strong>of</strong> Supply (MOSEC). This <strong>of</strong>fi ce<br />

designed the wind tunnel for Vernon, based on that at Peenemünde.<br />

In the early 1950s, the French army created a Franco/German working group led by Pr<strong>of</strong>. K. Rawer in<br />

Freiburg (Germany) with the objective <strong>of</strong> performing studies <strong>of</strong> the ionosphere using sounding rockets.<br />

From 1956 onwards, this group was supported fi nancially by the German government <strong>and</strong> became one <strong>of</strong><br />

the Fraunh<strong>of</strong>er Institutes.<br />

<strong>The</strong> LRBA also contributed substantially <strong>to</strong> the construction <strong>of</strong> the engine for the French Diamant rocket,<br />

the fi rst stage for which was derived from the V2.<br />

Another German team <strong>of</strong> about 50 rocket-engine experts worked under Pr<strong>of</strong>. Eugen Sänger for the French<br />

Air Ministry on rocket-powered jet planes. Sänger had developed the fi rst hypersonic aircraft <strong>and</strong> tested<br />

it in wind tunnels in 1943. He returned <strong>to</strong> Germany in 1953 <strong>to</strong> become Direc<strong>to</strong>r <strong>of</strong> the Jet Engine Physics<br />

Institute in Stuttgart.<br />

<strong>The</strong> United Kingdom’s war booty<br />

From the beginning <strong>of</strong> World War II, the Nazi propag<strong>and</strong>a machine spread news <strong>of</strong> Germany’s development<br />

<strong>of</strong> a novel ‘wonder’ weapon <strong>to</strong> be used against Engl<strong>and</strong>. <strong>The</strong> British government was worried <strong>and</strong><br />

its intelligence service received a high-priority order <strong>to</strong> gather information on this novel weapon. <strong>The</strong> fi rst<br />

extremely useful piece <strong>of</strong> V2-related information that the British government obtained was a comprehensive<br />

<strong>and</strong> detailed description <strong>of</strong> German armaments development work, in the form <strong>of</strong> a letter delivered in<br />

November 1939 <strong>to</strong> the British Embassy in Oslo. This letter from a German scientist, a Nazi-opponent <strong>and</strong><br />

pacifi st, contained a detailed description <strong>of</strong> the Peenemünde rocket centre <strong>and</strong> the planned development <strong>of</strong><br />

rocket types A1 <strong>to</strong> A4 (V2). Hans Kummarow was assassinated <strong>to</strong>gether with his family more than three<br />

years later (in 1943) as a member <strong>of</strong> a German anti-Hitler resistance organisation. Those pursuing him had<br />

not been aware that he was the author <strong>of</strong> the letter delivered <strong>to</strong> the British Embassy in Oslo.<br />

A second very important V2-related piece <strong>of</strong> information emerged from a misguided test rocket, which<br />

l<strong>and</strong>ed by mistake in Sweden in 1943. <strong>The</strong> surviving V2 hardware from this fl ight was immediately taken<br />

<strong>to</strong> Engl<strong>and</strong> in a small plane, where a thorough technical analysis made the British authorities certain that<br />

this very powerful rocket represented a great danger <strong>to</strong> the security <strong>of</strong> the population <strong>of</strong> southern Engl<strong>and</strong>.<br />

<strong>The</strong> response <strong>of</strong> the British military authorities was the heavy bombardment <strong>of</strong> Peenemünde by the Royal<br />

Air Force on 18 August 1943. This devastating bombardment not only killed some 600 rocket experts, but<br />

also resulted in the destruction <strong>of</strong> the technical facilities, leading <strong>to</strong> a major delay in V2 qualifi cation <strong>and</strong><br />

testing.<br />

In March 1944, Prime Minister Churchill gave the order for the British Secret Service <strong>to</strong> kidnap von Braun<br />

<strong>and</strong> bring him <strong>to</strong> London. However, as this proved not <strong>to</strong> be feasible in practice, it was later changed <strong>to</strong> an<br />

order <strong>to</strong> recover a fully-functional V2 rocket <strong>and</strong> bring it <strong>to</strong> Engl<strong>and</strong>. By chance, this order was fulfi lled<br />

in mid-1944, after a V2 test rocket launched from Peenemünde l<strong>and</strong>ed on the banks <strong>of</strong> the river Bug in<br />

Pol<strong>and</strong>. From there – having been pr<strong>of</strong>essionally dismantled by the Polish resistance – it was transported<br />
