Lockheed SP-2H Neptune 216/V
- The 216 stood for many near the gate at NAS Valkenburg. When NAS Valkenburg was closed the Neptune was transported to NAS De Kooy. The Neptune was in very bad shape after many years standing outside. When it arrived at De Kooy it first got the necessary maintenance before it was put at its current place.
- 18 Neptunes have been in service with the Royal Netherlans Navy 201 - 218
