why do some jets need a chute to slow them down on landing?

can somebody let me know why some need it and some don't? do some require faster landing speeds? is it because of shorter runways? both? any other?

thanks!

The jets are not always "empty" when landing and/or you land on a short runway...

In short:

It is always easier to replace a drag-chute than replacing the brakes and/or even replace the whole gears/airframe.

Just because you hadn't a drag-chute.

Maintenance on landing gear and brakes costs more then stuffing a parachute back in something, or even replacing it all together.

Also, shorter landing roll for small or icy runways. Norway and Canada are buying F-35A's, but with chutes so they can utilize them in the Arctic.

Herring is safe.

The F-117 would use the chute only in extreme situations. I remember being at Holloman AFB in 1996, there was a thunderstorm on the way and it was already raining. The 5 jets airborne had to get in quick, so to help slow them down faster to get off the runway for the next jet, they used the chutes.

so why most of the Russian jets use drag chute?

I'll venture a guess: They're designed to operate off short runways, with rough surfacing in the summer and snow and ice in the winter.
