Why did HMS Hood's loss have such cultural force?

Why does HMS Hood's loss have such a deep cultural impact?

Her reputation for size and power made her seem nearly unsinkable, so her sudden loss produced a Titanic-like psychological shock.

The comparison with Titanic rests on the confidence both ships inspired through size, technology, and apparent invulnerability. Their sudden destruction reversed that confidence in a single shocking event. Hood's cultural power therefore comes from the collapse of an icon as well as the lives lost. The analogy explains why her memory can loom larger than other wartime sinkings with comparable or greater casualties.
