HM Submarine Ocelot

Launched in 1962, HM Submarine OCELOT was the last warship built at Chatham for the Royal Navy. She was one of 57 submarines built between 1908 and 1966 and served during the Cold War in the Arctic, Atlantic Ocean, Mediterranean and Baltic Seas.

Equipped with a stealthy diesel electric engine Oberon class submarines such as OCELOT made for the perfect surveillance vessel and were selected to undertake missions in the deep waters of the world’s oceans – some of which remain top secret!

Although the Ministry of Defence have yet to release in-depth papers regarding OCELOT’S service, we know that this remarkable vessel clocked up over 90,000 miles and engaged in exercises and trials in nearly every corner of the world, including during the Cold War in the Arctic, Atlantic Ocean, Mediterranean and Baltic Seas.

She remained in service until 1991.
