  • Titus French sounding rocket. Sounding rocket derived from the first two stages of the Berenice test vehicle. The two stage vehicle consisted of 4 x SEPR P167 stabilisation rockets around a Stromboli 739 first stage, topped by a stretched Stromboli SEPR 740-3 second stage with four fins. The launches were made from Chaco in collaboration with the Argentinian agency CNIE. More...

Associated Propellants
  • Solid Solid propellants have the fuel and oxidiser embedded in a rubbery matrix. They were developed to a high degree of perfection in the United States in the 1950's and 1960's. In Russia, development was slower, due to a lack of technical leadership in the area and rail handling problems. Solid propellants have the fuel and oxidiser embedded in a rubbery matrix.
