187 F22s should be enough with their high kill ratio. The F35s would be used off carriers or whenever the F22s are busy doing other patrols.
One problem - they are high maintenance jets and about a third of them are going to be deadlines for repairs or maintenance at any time.
Further, there is currently an unresolved issue with the oxygen systems on board the craft, so pilots are at risk and many won’t fly until that is fixed.
Next, many will have to be kept in reserve as replacements for ones that crash or are damaged - as no more will be made.
And the way the government is leaning, there won’t *be* any 35s to fill in.
