The Boeing JSF is designed to accelerate faster and be more agile than any other legacy strike fighters. The 2-D thrust-vectored P&W F119 derivative engine will enable pilots to exploit the aerodynamic qualities of the aircraft. High commonality is essential for affordability - to lower the cost of procurement and ownership. Development, production, and support and training costs are dramatically reduced because the Boeing JSF is designed to be approximately 85% common among its three multi-service variants.
