After more modern torpedo attack aircraft were developed, the Swordfish was soon redeployed successfully in an anti-submarine role, armed with depth charges or eight "60 lb" (27 kg) RP-3 rockets and flying from the smaller escort carriers, or even merchant aircraft carriers (MACs) when equipped for rocket-assisted takeoff (RATO). Its low stall speed and inherently tough design made it ideal for operation from the MACs in the often severe mid-Atlantic weather. Indeed, its takeoff and landing speeds were so low that, unlike most carrier-based aircraft, it did not require the carrier to be steaming into the wind. On occasion, when the wind was right, Swordfish were flown from a carrier at anchor.
