The three airstrips at Iron Range Airfield were constructed between mid 1942 and 1944 as part a US bomber airfield. Gordon Strip has been upgraded as Lockhart River Airport, located about 4km west of the Lockhart River Aboriginal community, while the other two strips are abandoned. Wartime access was from a jetty at Portland Roads, now a 35km 4WD trip to the north.

Claudie Airstrip, southeast of the airport, is a bitumen surface about 2000m long usually covered with seasonal grass. Wartime clearing of rainforest is still evident as are bitumen sealed dispersal bays at the north end. At the south end of the strip a bitumen taxiway heads towards the longer New Claudie Airstrip, which was never sealed. The latter is parallel to Claudie Strip, about 1300 metres eastward. The strip and connecting taxiways are now covered by rainforest regrowth.

Two Heavy Anti Aircraft (HAA) 3.7-inch gun stations also survive. Gun Station 446 is located 1000 metres north of Gordon Strip, just west of a section of the Lockhart River-Portland Roads Road. Located in dense rainforest, known surviving concrete elements include: a semi-underground Command Post (CP); three of four in-ground octagonal gun emplacements (in an arc west and north of the CP); one of four semi-underground magazines (south of the CP); and a slab of the mess kitchen southeast of the CP.

Gun Station 447 is located 1000 metres west of Claudie Strip, in open woodland on a high bank above the Claudie River. Concrete components include: the CP; four gun emplacements (in an arc south of the CP); four magazines (west and northeast of the CP); and the concrete slab of the mess kitchen is located about 180 metres north-west of the CP.
