ACNS Architecture


• The optimization algorithm simulates the

human common-sense:

– Multi-objective optimization process; the

algorithm finds the optimal solution for several

concurrent objectives

– Allows for solutions that may be sub-optimal

for one platform; but are the best global

solution

• Solutions with low computational complexity

• Obstacle avoidance in compliance with the

International Regulations for Preventing

Collisions at Sea (COLREGS)

Summary

• USV and UAV combined operations are a proven reality

• USVs offer flexibility and are a real force multiplier

• But this works both ways:

– Small navies can use them very effectively against our conventional

naval forces

– Need to include them in war games and operational studies on both

sides

– We must not ignore them because we do not like the consequences

• Large USVs are coming, for offense and ISR

– Analogous to where UAVs were 10 years ago

• This is the way of the future!
