Which of the following characteristics does NOT apply to solid-fuel rockets?

Solid-fuel rockets are known for various characteristics, but their application in large missiles is not a defining feature. Instead, solid-fuel rockets are commonly used in smaller missile systems, tactical rockets, and pyrotechnics. They are valued for their simplicity, reliability, and ease of storage.

Stability is a crucial characteristic of solid-fuel rockets, as they provide a consistent thrust once ignited and maintain their flight path due to the inherent design of the rocket. When it comes to cost, solid-fuel rockets tend to be lower in cost compared to liquid-fuel alternatives, as they require less complex infrastructure and are straightforward to produce. Additionally, the manufacturing process for solid-fuel rockets is typically less expensive, making them favorable for various military applications.

In contrast, large missiles often require more advanced guidance systems, which can lead to the use of more complex liquid-fuel engines that can adjust thrust during flight. Thus, while solid-fuel rockets serve valuable purposes in certain applications, they are less commonly associated with large missile systems.
