1. Development cost: - stages - engineering - system integration and test 2. Vehicle manufacturing cost: - stages - engines - system integration and test 3. Refurbishment cost: - inspection, deassembly, assembly - electronic equipment exchange/repair - structure and heat shield repair and refurbishment - rocket engine refurbishment 4. Direct operations cost: - technical system management - pre-launch operations (assembly/checkout) - launch and mission control (incl. software) - propellants - recovery and transportation 5. Indirect launch operations cost: - launch site administration - engineering support - facilities maintenance and amortization. The annual number of launches has a major effect on the operations cost. The indirect operations cost charge per Hight decreases with a higher launch rate of smaller vehicles, as well as the development cost amortization burden. However, the other direct operations cost are dominating and do favour larger vehicles with
