If the RAF send the display aircraft and crew it will be very interesting. I've said before, the GAF say both aircraft meet the Threshold requirement. Chinook is about a third of the price to buy, is mature, and in series production / service with several European air arms that the GAF could request support from. Block II is coming, but it's a low-risk incremental improvement. Proposed Block III with the bigger engines/upgraded transmissions will further close the gap. They have no need for the cost, weight and complexity of a marinised platform and, if the Israelis are thinking Chinook, they will likely be the only export customer. The GAF may wish to ask the Canadians how that feels...... Unless you want to lift something really, really heavy or go to war on a ship, then -53K looks like it will struggle against the default answer - "Chinook". That all said, -53K might be a better option for France if it decides to "go large"....
