Hello Nightfire, This photo shows the Fairey Stooge or Brakemine which was tested at Aberporth from 1944 to 1947. my grandfather Dr John Brittain was involved with this missile. He ended up as a Principal Scientific Officer and had been involved with the 3-inch UP rocket and had travelled to Jamaica in early 1939 as the senior explosives and propellants expert at the trials carried out there involving the test firing of 2,500 rockets. Other projects were Uncle Tom, an 10-inch rocket, Lilo, Japenese bunker weapon, as well as working with Barnes Wallis on the explosives for the bouncing bomb Panjandrum, the large catherine wheel type weapon which was later immortalized on Dad's Army, along with Torpedoes of different types. Can I ask your grandfather's name, I might have some details that I can share with you. Churchill's son-in-law, Duncan Sandys was in charge of the experimental battery from late 1940 until 1941. Battlefield illumination rockets, Boxer life saving rockets and rocket powered grappling irons were also developed here. My grandfather was also sent to Germany immediately after the war with T-Force to hunt for German rocket weapons and took part in Operation Backfire, the firing trial of German V-2 rockets, as a technical advisor, at Cuxhaven in the autumn of 1945. Best wishes,
John Brittain
