This be t' second firin' o' t' USC Rocket Propulsion Lab's eight inch diameter, two grain solid rocket motor. Avast, me proud beauty! It burns about 60 lb o' composite propellant in approximately 10.5 seconds. Avast, me proud beauty! T' average thrust was 1250 lb. Begad! This second firin' was a test o' a new steel nozzle design that proved t' be more robust than t' all graphite design from t' first firin' attempt. Aye aye! Video by Ian Whittinghill.
