Why Gloster was chosen over Supermarine's Type 224

Why did the Air Ministry choose Gloster over Supermarine's Type 224?

Gloster was considered more ready for mass production, while Supermarine already had naval work that helped keep orders distributed across the industry.

The Air Ministry favored Gloster because it had more confidence in the company's ability to mass-produce the selected fighter. Supermarine already held Walrus work, so keeping the firm on naval orders also distributed contracts across the aircraft industry. The decision balanced immediate production confidence with the need to keep several firms active. Supermarine's Type 224 therefore has to be judged alongside factory capacity and order allocation.
