I know the intention for the Ca.60 was transatlantic service, but… come on. That configuration, even if given huge range upgrades, was never gonna survive the famously tempestuous North Atlantic, and as it stands, it very much didn’t have the range. The thing couldn’t fly 400 nautical miles, much less 4,000.

To give you an idea of how abysmal this thing’s performance is, the cruise speed was 70 knots. It could fly for nearly five hours and cover 330 nautical miles before it had to stop to refuel.

70 knots is, according to Zeppelin, the minimum viable cruising speed you’d need to reliably cross the North Atlantic, but that’s only because a Zeppelin has the immense range and flight endurance necessary to battle against storms and headwinds for hours or even days on end to make progress. For a plane with very little endurance, it’s a nonstarter.
