'non-missile-propelled' originates from the prefix 'non-' meaning 'not,' combined with 'missile,' from Latin 'missilis,' meaning 'that may be thrown,' and 'propelled,' from Latin 'propellere,' meaning 'to drive forward.'

'Missile' changed from the Latin word 'missilis' to the modern English word 'missile,' and 'propelled' evolved from the Latin 'propellere' to the modern English 'propelled.'

Initially, 'missile' meant 'that may be thrown,' but over time it evolved to mean 'a self-propelled weapon.'
