Depending on weather, which effects both radar and passive sonar ranges - Yes, but both have to get into strike position ahead of the target.
This usually requires a bit of flank/full surface speeds, using up a lot of fuel.

Any target course changes can ruin the setup phase, unless the course is towards the sub.
