The Black Brant family of sounding rockets was initially derived from the British Skylark sounding rocket and the Raven solid fuel engine. The Canadian Armament Research & Development Establishment (CARDE) acquired a cluster of Skylarks from Britain and working in conjunction with Canadair of Montreal, Bristol Aerospace in the UK and Bristol Aerospace Canada they created what became the Black Brant.

The Skylark/Raven was 17 feet in length. Bristol Aerospace of Canada were given a contract by the Canadian government in 1957 and then added a 7 foot long nosecone creating a vehicle 24 feet long and 17 inches in diameter. Lionel A. Wilkinson, a chemist working at CARDE, developed a high-energy propellant which he called Cardeplex. This propellant was designed to be able to withstand a wide range of temperatures (-65F to +160F) and was poured directly into the rocket casing. Fuel was derived from a polyurethane rubber with ammonium perchlorate oxidizer and a cocktail of stabilizing compounds. CARDE also redesigned and improved the engine to meet specifications for Bristol's requirements.
