The raptors are designed to fight against the USSR before it collapse in the year 1991. It is the most advanced and bullet-proof fighter jet in the air so far, however, there are currently 151 in total of the planned 187 and the program has been canceled by the US President, Barack Obama due to the following reasons:1. Building of a plane involved contractors of 44 states which incurs a very high cost.
2. The cost of each plane has risen to USD142.6 million each.
3. Statistically, every 1 hour of flight requires 18-20 hours of maintenance.
4. Records showed 1 critical failure in every 1.7 hours of flying time.
5. Unable to communicate with other models of aircraft due to their unique communication and avionic technologies.
However, if the program has been canceled at this point of time with only 151 planes in the inventory instead of the 187 planned and the 243 required in the US air space, the cost of each plane become USD356 million each due to the design, research and development cost that has been invested by the Government. It might be a real technological failure program that leads to the cancellation.
