In 1963 the Sikorsky HSS1-fleet was joined by three former Sabena Sikorsky S-58 transport helicopters. The primary role was to support the Nike Air Defence installation based in West-Germany (Short Range Transport-flight).
Two additional helicopters were added to the fleet in 1969. These were fitted with a VIP-interior for the use of the members of the Royal Family and members of goverment.
After the introduction of the Sea Kings in 1976 all S-58Cs were withdrawn from service.
