Measures for Progress: A History of the National Bureau of Standards

The "Bat," borne by a Navy torpedo bomber, rides with folded tail fins until, upon
release, they open into proper flight position.
The first fully automatic guided missile to be successfully used in combat, the Bat
was designed for use against enemy shipping, and particularly against surfaced sub.
marines. The Bat's outstanding features were its self-guidance after release, its long
range, high accuracy, low angle of flight, and high pay load.
The "Pelican," developed with the cooperation of the Navy Bureau of Ordnance and the
MIT Radiation Laboratory. Here it is rigged with instrumentation for flight tests, the
16 mm gunsight aiming point camera directly beneath the wing pointing at a panel of
signal lamps indicating radar controls being applied, and the 16 mm camera, slightly
lower and forward, pointing at the ground ahead of the glider.
