Advantage of solid-fuel ICBMs over liquid-fuel ICBMs
- In the liquid fuel ICBMs, fuel must be added relatively close to the launch, and they cannot remain fueled for prolonged periods.
- Solid-fuel ICBMs are fueled during manufacture and can be used when needed.
- They are more rapidly usable in a conflict, reducing the opportunities for opponents to counter.

Cruise Missile |
| It is propelled only briefly after the launch. |
It is self-propelled till the end of its flight. |
| Similar to a rocket engine (carries an oxygen tank). |
Similar to a jet engine (which uses atmospheric oxygen for combustion). |
| It is a long-range missile because there is no fuel requirement after its initial trajectory. |
It is a short-range missile because it requires fuel till the end of its flight to guide it constantly. |
| It leaves the earth’s atmosphere and re-enters it. |
Its flight path is within the Earth’s atmosphere. |
| Low precision as it is unguided for most of its path, and its trajectory is influenced by air resistance. |
High precision as it is constantly guided. |
| Heavy payload carrying capacity. |
Limited payload carrying capacity. |
| Can carry multiple payloads. |
Usually carries a single payload. |
| Developed primarily to carry nuclear warheads. |
Developed primarily to carry conventional warheads. |
| E.g., Prithvi, Agni, and Dhanush missiles. |
E.g., BrahMos missiles |
