I suspect this is MQ-9 Reaper Block 5 ER - from the GA website:
Predator B continues to improve and evolve, making it more relevant for its customers' emerging needs. A new variant, Predator B ER, has been designed with field-retrofittable capabilities such as wing-borne fuel pods and a new reinforced landing gear that extends the aircraft's already impressive endurance from 27 hours to 34 hours while further increasing its operational flexibility. In 2016, the aircraft will evolve again when its wingspan will grow from 66 feet to 79 feet to hold the fuel that was previously stored in the fuel pods. This configuration will deliver 42 hours of endurance.
At the same time, they are working on getting MQ-9 fully certified for European airspace (don't forget that France and Italy also operate MQ-9). Here is a link explaining this:

So now that UK Reaper can fire dual-mode Brimstone as well (
MQ-9 Reaper Fires Brimstone Missiles) then I suspect that MQ-9 Block 5+ ER that is certified is going to be SCAVENGER and that is what the PM is talking about.

PS. Delivery date is expected from 2019 according to the DoDBuzz link above.
