Royal Navy cruiser aviation across primary and distant theaters

In a primary fleet theater, carriers handled most reconnaissance and cruiser aircraft became backup scouts and anti-submarine patrol assets. In secondary and tertiary theaters, those same aircraft could become the principal means of finding surface raiders, as in the search for Admiral Graf Spee. Distant cruisers had to remain useful while supply shipping concentrated on the main fleet, making self-support a force-structure requirement. Town-class planning considered as many as six aircraft, split between assembled machines and boxed replacements, while ships more often carried two ready and two boxed aircraft in service. Reliability, easy repair, and the ability to operate on a logistical shoestring mattered more than peak performance, shaping the Royal Navy's attachment to aircraft such as the Supermarine Walrus and Fairey Seafox. The tradeoff was 90-percent availability from a dependable system against only 50 percent from a more advanced one, with the reliable option often cheap enough to buy in greater numbers. Sea control covered friendly movement and the destruction of enemy forces that could deny it.
