What does the LAU-147 use to prevent inadvertent firing while the missile is loaded?

• A. In-flight timer
• B. Reversible inflight lock
• C. Mechanical safety pin
• D. Electronic fuse lock

Answer: (B)

A safety mechanism at the launcher level is used to keep the missile from arming while it’s still mounted on the aircraft. For the LAU-147, that safety is the reversible inflight lock. When the missile is loaded, the lock engages to physically prevent the arming signal from reaching the fuze, guarding against inadvertent firing due to handling or vibrations. It is designed to be reversed or released as part of the proper launch sequence, so arming can occur only when the launch condition is met. This makes it the best choice compared with other options, which describe functions not specifically tied to preventing inadvertent arming while the missile is loaded.
