During the development of the Advanced Tactical Fighter (ATF) the U.S. Air Force undertook a demonstration and validation program undertaken by the Air Force from 1986 through 1990. At that time, two aerospace teams headed by Northrop and Lockheed were selected to develop and fly prototype aircraft which ultimately became the F-22. Throughout the 50 months of the competition, each team was required to make design choices that would produce maximum effectiveness while remaining below cost and weight constraints set by the Air Force.
The Lockheed team, consisting of Lockheed, Boeing, and General Dynamics, hired STR to assist in designing the aircraft. STR used its OME-III software system to evaluate the effectiveness of alternative designs proposed by the Lockheed team. OME-III used advanced multi-staged game theory algorithms to optimize both US and Soviet strategies and tactics each time a new design was proposed. By doing so, STR was able to demonstrate the effectiveness of the ATF in a simulated air-ground campaign in central Europe (the area of greatest concern at that time).
In addition to evaluating the effectiveness of alternative designs, STR showed senior management from Lockheed, Boeing, and General Dynamics how the problem of reducing costs and weight while minimizing the impacts on capabilities could be formulated as a classic Knap Sack problem. In doing so, STR eliminated weeks of frustrating trial and error and showed the Lockheed team the optimum path to reducing costs and weight of the prototype aircraft.
Ultimately, STR’s contributions to the design helped the Lockheed team win the contract to develop and build the F-22 aircraft.
