The SeaWolf Hull array will pick up supertankers at 12kts up beyond 30nm and the sphere array will pick up supertankers at 12kts beyond 25nm.
Also, the Han at 5kts will light up the Sphere array beyond 12nm and will even pick up a Collins at 5kts around 4-5nm.
It's important to consider the SL's of these objects and the speeds they are travelling at.
I can email you two of my test scenarios if you would like.
