Basically, a deactivated missile. Typically, an inert missile will either be a purpose built dummy, or a live missile, with its propellant and warhead removed.

Inert means they don't react. Group 18, the noble gases, are inert.
inert gas inert gas inert gas
no oxygen is not a inert gas
Gold is active, or at least not inert. Only the noble gases are inert.
The inert gas had no effect on the experiment. The bomb was inert and failed to explode.
An air-to-surface missile is a missile which is fired from an aircraft to the ground.
argon is an inert gas
Carbon monoxide is not an inert gas.
group 18 elements. they are inert because they have completely filled orbitals and and stable or chemically inert.
Missile fuel
Helium is an inert gas, and seldom reacts with other elements. After the explosion, they discovered the inert bodies of the two guards. The inert Lunar Rover is still parked at the landing site of Apollo 17, awaiting a new battery and a new driver.
