Claims that submarines could evade the Helix may come from peacetime encounters governed by tight identification rules. In war, crews may attack suspected contacts before reaching the same level of certainty. During the Falklands War, weapons were dropped on false biological contacts, including schools of fish and pods of whales. Faster prosecution makes helicopters more dangerous to submarines and raises the risk of attacking the wrong contact.

Wartime rules make helicopter ASW more aggressive
Peacetime submarine encounters can make ASW helicopters seem less dangerous than they become under wartime rules.
