Almost definitely not.
Predator C has a MTOW of 8.255 tons, and it has an internal payload capacity of 1.6 tons and external payload capacity of 2.9 tons.
We don't know the MTOW of cloud shadow, but we know its total payload is 400kg.
13.5 tons is larger than the sort of male/hale uavs like reaper, global hawk etc, and is more closer to the weight of the 16.5 ton phantom ray ucav but still quite a bit smaller than the 20 ton x-47b.
13.5 tons is probably greater than the MTOW of the sharp sword that we currently know of as well.
Then the article is talking about a UAV being tested that we haven't seen yet.
