I have seen that question several times; wish I could ping everyone that asked.
The CF18 Hornet has a service ceiling of 50,000 ft.
The F22 Raptor has a publicly announced service ceiling of 65,000 ft.
That should be sufficient answer to your question.
Thank you but another dumb question; hate to show my ignorance - but can’t missiles take them out without sending aircraft...nothing from Vandenberg AFB or MT? I know our aircraft have specific capabilities and missions but what are our missiles for?
