Wait. I stand corrected. The Navy used the H-46 Sea Knight for SAR and then was replaced by the MH-60. Marines still use the H-46D with the witch’s t*tties intake screens, also known as “Pedro” for SAR at Air Stations.
Thank you, Patro!
Actually, before the H-60 series, the Navy used the SH-3 Sea King primarily for ASW and SAR (e.g., plane guard). For personnel & cargo transport, the Navy used the CH-46 Sea Knight. The Marines have replaced their MH-46s with the MV-22 Osprey.
