From the FI article on the award:
.....a roughly 50-aircraft unmanned aircraft system (UAS) fleet to partner with the 108-fleet Boeing P-8A Poseidon....
The two fleets will focus on different missions. The P-8A will continue the P-3C’s primary focus on anti-submarine warfare, while the BAMS fleet will focus on surface and overland surveillance across a wide swath of territory.
....each responsible for maintaining a persistent surveillance vigil over a 2,000nm radius.
.... the BAMS aircraft also will be tasked to dive to low-altitude, requiring a new level of high- and low-altitude agility for a UAS fleet.
More UAV's in the air, it will be interesting to see how this all plays out in the coming years.
