What it is Filled
The CH-124 Sea King was Canada's military maritime helicopter variant of the Sikorsky S-61/SH-3 Sea King family, a twin-turboshaft, amphibious rotorcraft used primarily for shipborne anti-submarine warfare.
In scope
- CH-124 designation, type identity and configuration lineage
- Maritime airframe, propulsion and folding arrangements
- Aircraft interfaces with shipboard handling and accommodation
- Configuration-dependent mission equipment and capabilities
- Maintenance evidence, operating limitations and retirement disposition
Out of scope
- King as a title, person or unrelated registry concept
- Other Sea King aircraft types except for identification and lineage links
- CH-148 Cyclone design and operation
- Individual aircraft ownership, flight logs and component histories as standalone records
- Warship design, squadron organisation and mission planning
- Detailed weapon employment procedures and independent models of carried equipment
Why it exists Filled
Enable an agent to recognise the CH-124 Sea King aircraft type, distinguish its configurations, and determine what evidence is needed to assess an example's capabilities, condition and permitted use.
Distinguishing features Filled
- Require documentary identification as CH-124; a Sea King silhouette or name alone does not establish the Canadian type.
- Check the combination of shipborne helicopter configuration, folding rotor and tail, amphibious hull and twin turboshaft propulsion; these corroborate identity but are not unique identifiers. [RCAF aircraft profile](https://www.canada.ca/en/air-force/services/aircraft/ch-124.html)
- Separate the aircraft's documented configuration from equipment visible today; removed mission equipment does not by itself change type identity.
- Treat CH-148 Cyclone as a separate successor type, not a CH-124 configuration. [National Defence retirement announcement](https://www.canada.ca/en/department-national-defence/news/2018/11/canadian-armed-forces-honour-the-long-serving-ch-124-sea-king-helicopter.html)
