The program has not cost $1.5 trillion so far.

The Pentagon is spending about $11 billion on the F35 for the entire fiscal year (2% of its budget).[1] About ~$30 per tax payer.

$1.5 trillion is the 55 year projection on the total cost of the program over that time frame. Including purchase, operation and upkeep. Or $27 billion per year for everything.

It has cost roughly $100 billion so far over 20 years.

Not "so far". That's the projected total lifetime cost of the entire program. That includes everything -- paying all the engineering and development costs, all the testing, all the airplanes, all the logistics and spare parts and support -- over 50 years.

Still better waste of money than healthcare for all!! :)
