I can only reiterate what Rossian said back in September ‘’Training is vital’’
Your clean-sheet design may evolve into the most capable platform ever invented, incorporating the perfect blend of sensors, weapons, a five star galley and multiple lavatories. But without a well-trained, well-motivated, well lead crew it might as well stay on the ground.
You also have to remember that training is a continuous requirement as we live in a world where everything changes and evolves.
