Heinkel He 115: Recovering the Fjord Wreck with Mud Lances

#HeinkelHe115 #AviationHistory #PlaneCrash #AircraftRecovery #WreckageRecovery Heinkel He 115 lay upside down in Norway’s Hafrsfjord for decades—sealed into low-oxygen silt that preserved paint, but also created a brutal suction trap. In September 2005, a side-scan sonar test logged a clean aircraft-shaped anomaly at about 151 feet, near Stavanger. Recovering Heinkel He 115 wasn’t just about lifting weight—it was about breaking “stiction” without snapping the wings at the roots. Before any hoist, the Royal Norwegian Navy cleared the hazard: two SC 250 bombs in the inverted fuselage. With the site safe, engineers planned a controlled aircraft recovery built around mud lancing. Divers injected high-pressure water and air under the wing contact zones to liquefy packed silt and equalize pressure, turning a vacuum extraction into a manageable lift. On June 1–2, 2012, Heinkel He 115 was raised slowly from the seabed, pausing around 65 feet for rigging checks before surfacing—its dark camouflage and the “8L+FH” codes still legible. The wreckage recovery continued onshore with immediate freshwater rinsing and careful disassembly so the airframe could fit the museum’s large desalination tank, the “Aquarium.” There, circulating freshwater pulls chlorides from seams and double skins to prevent exfoliation corrosion.
