Pada puncaknya, seri Sikorsky SH-3 untuk AL sangat luas dipakai dan sukses sebagai platform antikapal selam dan operasi SAR. Pengembangan dimulai dari proposal kontrak AL AS pada 1957 yang akan memproduksi purwarupa yang diterbangkan pada 1959. Pengoperasiannya akan secara resmi dilakukan setelah dua tahun penerbangan purwarupanya.

Pada pengoperasian, SH-3 berhasil menjalankan peran pentingnya sebagai perlindungan terhadap kapal selam musuh. Helikoter ini menjadi platform utama, dengan menggunakan radar sonar kedalaman AQS81B, MAD, sonobuoys dan fleet-wide linkup, Sea King memberikan data akurat untuk perlindungan dari serangan musuh. Persenjataan standarnya terdiri dari 2 atau 4 torpedo bersama dengan “chaff pods” untuk perlindungan diri terhadap misil musuh. Persenjataan lain dapat terdiri dari misil anti-kapal atau “depth charges” jika dibutuhkan.

SH-3 dikembangkan untuk menjalankan peran versatil (bermacam-macam), dapat digunakan untuk medis dan transpor secara efisien dan efektif seperti saat digunakan untuk peran pertempuran. Sebagai transpor medis, lebih dari 20 pasien dapat diangkut, atau personel ini dapat diganti dengan 9 tandu medis. Sebagai tambahan, sekitar 28 personel tempur dapat diangkut jika dibutuhkan dalam peran transport militer. Menariknya desain Sea King adalah dia dapat mendarat di air karena desain amfibinya, walaupun dengan waktu mengapung yang terbatas.

SH-3 muncul dengan peran penting baru dari waktu-ke-waktu, yang sangat menarik adalah sebagai Marine One, transport VIP khusus untuk Presiden AS dan dioperasikan oleh Marinir AS. SH-3 juga berperan dalam recovery awak Apollo 14. Dalam area AS, saat ini, SH-3 mulai digantikan perannya oleh SH-60 Sea Hawk yang lebih baru.
