Why Germany still builds pocket battleships first

Would Germany still build pocket battleships if Britain had more scout carriers?

Probably. The Deutschland class remains close to what German industry can support, although its air defence could improve.

The Deutschland-class ships remain close to the best surface combatants Germany can build with its available industry. More British carriers could encourage better air defence, while the broad arrangement and two large 11-inch turrets would probably remain. Aircraft from a scout carrier could damage a raider before the cruiser hunting group arrived. The comparison with Bismarck concerns that sequence: an air attack restricts escape and surface ships complete the engagement.
