Why Victorious attacked Bismarck with Swordfish

If Albacore entered service early, why did HMS Victorious still use Swordfish during the Bismarck operation?

Albacores belonged to Victorious's intended full air group, but the new carrier sailed before that group was ready and instead embarked nine Swordfish and six Fulmars while ferrying forty-eight crated Hurricanes to Malta.

Albacore availability did not mean every new carrier had a worked-up Albacore squadron ready to sail. Victorious's intended group included Albacores from 827 and 828 Squadrons, but the carrier joined the Bismarck operation before completing that organization. She therefore carried nine Swordfish and six Fulmars for combat. Forty-eight crated Hurricanes bound for Malta also occupied much of the ship, making this an air-group readiness and mission-loading problem instead of a simple aircraft preference.
