Thats the one
below is a bit of info on this weapon.
The Bat Missile
The Bat was a glide bomb carried by a Navy PB4Y-2 Privateer patrol bomber or other aircraft and was designed to destroy ships and offshore enemy targets.Visual contact with the target was not required.
Launching altitude: 15,000 to 25,000
Launching speed: 140-210 knots
Range: 15 to 20 miles from its target
Payload: a 1,000 pound general purpose bomb warhead.
The Bat was steered by controllable wing-mounted elevons driven by autopilot servomotors linked to the radar guidance system. The missile had fixed tail surfaces and was gyro-stabilized.
Length: 11 feet 11 inches
Span: 10 feet
Empty weight: 600 pounds

Why a Bat?
When hunting or traveling in environments where visibility is poor, several species emit sound waves, then use their auditory systems to interpret reflected waves from prey or objects in their travel path. This ability is termed echolocation. By emitting a series of ultrasounds that either sweep from a high to low frequency or vary around a frequency, bats can distinguish, locate, and target prey.
The same idea applies to the Bat Missile. By transmitting radio waves, then interpreting the reflected waves with its radar receiver, the weapon guides itself to the target, even if the target moves after launch.
the Bat went overseas and eventually saw combat service in 1945, and destroyed several Japanese ships off the coast of Borneo including a destroyer. Several Bat Missiles were also fitted with modified radar systems and destroyed Japanese-held bridges in Burma and other areas. Thousands of Bat missiles were produced and went through several modifications.
