Swordfish aircraft against Falklands-era defenses

How would Fairey Swordfish fare against Falklands-era Argentine air defenses?

Their unusual flight profile might complicate interception, with a particularly plausible role against helicopters.

A very slow aircraft is not automatically an easy target for every air-defence system. Argentine defences may not have been configured to track and engage an aircraft with the Swordfish's unusual speed. That uncertainty prevents a simple survival prediction. Helicopters are also identified as plausible targets for the biplane in this counterfactual.
