In its time, the Limbo was considered one of the most effective anti-submarine weapons, with a success rate of around 60%. Developed by the British in World War II, it had a range of approximately 450 yards. However, like the Caribbean dance it shares a name with, the lower the bar, the harder it gets.

As expected, the Limbo was effective against submarines that were at shallow depths, and less so against deep-diving submarines. Still, this weapon was linked to the sonar system of the ship, allowing Naval officers to fire when the target was in range.

Although it was eventually retired in the ‘80s for more modern anti-submarine weapons, the Limbo sank at least five enemy submarines during the Falklands War, including the Argentine submarine Santa Fe.
