A multi-UAV swarm comprises one Communications UAV (CUAV) and two Mission UAVs (MAUV). The CUAV and at least one of the two MAUVs must remain operational for the swarm to complete its mission. Suppose that the CUAV has failure rate, r, each MUAV has failure rate, q, the rate of being shot down for any UAV is s, and that p is the probability that the swarm can recover from the loss of a MUAV. Draw a state diagram that represents the probability that the swarm will complete its mission; label the transitions with the rates and probabilities.
