Lieutenant Commander Andy Watts will talk about the work of 771 Naval Air Squadron at an event at the Maritime Museum in Falmouth on Monday November 5.
771 Squadron, based at RNAS Culdrose near Helston, provides Search and Rescue cover across the South West, 24 hours a day, 365 days of the year.
The squadron carries out more than 200 rescues a year, often putting crew members' own lives at risk, from plucking sailors to safety from storm tossed vessels to rescuing swimmers, surfers and cliff walkers in difficulties around the region's coastline.
Lt Cmdr Watts said: "Most people in Cornwall will have seen our red and grey helicopters flying across the Cornish coastline on daring rescue missions.
"This talk is a wonderful opportunity to hear first-hand accounts of the work that we do and get answers to those questions you've always wanted to ask."
The talk, entitled Search & Rescue in Pictures, Words & Deeds, is part of a programme combining a lecture and lunch, which explores different historical and nautical themes.
The lecture and set lunch starts at 12.30pm at the National Maritime Museum Cornwal on Monday November 5. Tickets cost £14.50. To book a place call 01326 214546.
