During the mid-Seventies, a sounding rocket with performances intermediate between those of Petrel and Skylark proved to be necessary for the SRC program devoted to high latitudes geophysics studies.
Bristol Aerojet Ltd developed a new version of the two-stage INTA-300. Flamenco sounding rocket, created by that firm for the Spanish INTA. This rocket, named Fulmar, comprised a 107 kN Heron booster and a 16.7 kN Snipe main stage. With a fairing (26 cm in diameter) slightly longer than that of the INTA-300, it was 7.47 m long.
Six Fulmars were launched from Andoya between 1976 and 1979. The two first were partial successes and the last a total failure. This lack of result contrasted with successes of the other Bristol Aerojet series and that series was abandoned after six launches.
