What is the primary purpose of the Jet Blast Deflector (JBD) on a carrier?

• A. Divert engine exhaust and debris away from personnel and equipment during aircraft launch
• B. Provide structural support for the catapult piston
• C. Absorb noise produced by aircraft engines
• D. House hydraulic fluid cooling system

Answer: (A)

Jet Blast Deflector’s main job is to redirect the powerful, hot exhaust and any debris from a departing aircraft away from people and equipment on the carrier deck. By deflecting the blast upward and outward, it protects crew, other aircraft, and deck facilities during launch and helps prevent damage from heat and flying debris. It isn’t meant to provide structural support for the catapult piston, absorb engine noise, or house a hydraulic cooling system—the primary purpose is safety through blast deflection.
