The HKP 4 served in the Swedish Armed Forces (Försvarsmakten) from 1963 until 2011 and proved a very versatile helicopter. The Air Force used it for rescue and medivac work, whereas the Navy used it for anti-submarine warfare and maritime surveillance. This example is now on display at the super Aeroseum.

Last flight of a Swedish Hkp4. It was delivered today to the Aeromusee at the former military airbase of Save, now known as Goteborg City Airport. The Swedish, who have all their military helicopters organized into a single independent command, still have one Hkp4 with some flight hours left. However, it is stored and not expected to fly again. After the withdrawal from use of the last Japanese Vertol 107 last year this leaves the USMC as the last operator of a handful of CH-46's.
