Which of the following aircraft are known to use rail launchers?

The Tornado and Typhoon aircraft utilize rail launchers as part of their weapon deployment systems. Rail launchers are integral to air-to-air missile systems, providing a stable platform for missile launch, ensuring precise targeting and effective use in combat scenarios.

The Tornado, operated by multiple air forces including the RAF, features capabilities for launching various air-to-air missiles, including the ASRAAM, from rail launchers located on its wings. Similarly, the Eurofighter Typhoon employs rail launchers for a range of munitions, allowing it to engage air threats effectively.

Other options include aircraft that might not typically rely on rail launchers for their specific operational roles or missile deployment systems. For instance, while the F-16 Falcon and B-52 Stratofortress are capable aircraft with versatile roles, their primary armament systems do not focus on the use of rail launchers in the same way as the Tornado and Typhoon. Hence, option A accurately reflects the use of rail launchers in these specific aircraft.
