Steel and glass filaments have been the construction materials for solid propellant rocket chambers of a 3 to 6 foot diameter range producted for four missile systems. Chambers as large as 22 foot diameter currently of interest for boosting space vehicles should use the construction material that makes the boosters 1 more reliable and 2 less costly andor minimum weight. In the absence of data on reliability and cost, weight comparison of the two construction materials is discussed in detail for a present size missile chambers and b a proposed very large booster. A booster of 260 inch diameter and 100 feet long between end dome tangency planes made from 18 NiCoMo 250 KSI yield strength steel may be expected to weigh more than a glass filament booster unless the winding problems associated with the large size are not readily solved.
