A 90-metre Oberon-class submarine sitting on the grass on the east bank of Otter Creek. The Ojibwa served in the Royal Canadian Navy from 1965 to 1998, a Cold War hunter-killer designed to disappear into the deep Atlantic for weeks at a time. She was towed and dragged to Port Burwell in 2012 to become the centrepiece of the Elgin Military Museum's outdoor collection.
Guided tours take you through the entire pressure hull — torpedo rooms, control room, sonar room, galley, the impossibly narrow officers' wardroom. The crew quarters are an eye-opener: 70 sailors sharing 60 bunks (the rest "hot-bunked" between shifts). Open daily from May to October; book ahead on summer weekends.
