History

Westland built the Sea King under licence with significantly more capable avionics and systems than the US S-61, giving the Royal Navy a highly capable ASW helicopter from 1969. The type saw combat in the Falklands War of 1982, and the SAR variant became the primary RAF and Royal Navy search-and-rescue helicopter for decades. The Sea King was replaced in UK SAR service by the Sikorsky S-92 (AgustaWestland AW189) from around 2016.

Variants

Royal Navy variants included HAS.1 through HAS.6 (anti-submarine), HC.4 (commando assault), and HAR.3/3A (search and rescue); export variants served with India, Pakistan, Norway, and Germany among others.

Where you'll see it

Served the Royal Navy from 1969 and the RAF in SAR roles; saw combat in the Falklands War; retired from UK SAR service by 2016 and from the Royal Navy by 2018.
