Which region is not a common area for OWS?

In the context of Common Operating Areas for Over-the-Water Surveillance (OWS) operations, North America is typically not considered a common area for OWS. This designation is based on the nature and historical focus of OWS, which primarily targets regions where significant maritime activities take place, including shipping routes, piracy, and illicit trafficking.

The Middle East and South East Asia are hotspots for maritime challenges and serve as critical areas for OWS due to ongoing geopolitical tensions, high shipping traffic, and specific security concerns. Africa also hosts several regions where maritime security is a pressing issue, particularly around the Gulf of Aden and the coast of West Africa.

North America, on the other hand, while having its own maritime security concerns, does not exhibit the same level of focus or necessity for OWS operations compared to the aforementioned regions. The nature of maritime threats in North America tends to be different, leading to less emphasis on OWS in that area. Thus, the correct answer reflects the lesser priority and different operational focus of surveillance activities in that region.
