Re-engining Jag's was moot anyways, use them till they last and then donate the shells to schools.There was never a "good" price.
In 2013, it was $3.7B for 120 Jaguars and the current quote is $2.4B for 80 Jaguars.
Current options are more than enough to cover it's role, and in actual combat, it's more of a liability, less of an asset. We are not going to fighting rag tag militia's where we can deploy a lumbering slug bug.
