submarine snorkel

Radar can also detect a submarine snorkel or periscope, and the wake it creates.

U-1276 was equipped with a submarine snorkel (underwater-breathing apparatus) when she sailed on her last cruise.

A submarine snorkel is a device which allows a submarine to operate submerged while still taking in air from above the surface.

A vehicle snorkel is the land-based equivalent of the submarine snorkel which allowed submarines to use diesel engines while submerged.

Cold rooms and calibration facilities at the Arctic Submarine Laboratory were used to solve the problem of icing on submarine snorkel head valves.

Two bays (Takt 9/10) were underneath box-like structures on the roof that allowed the extra height needed for the installation of periscopes, submarine snorkels and antennas.

Andromède, Artémis and Créole were fitted with GUPPY sails and Submarine snorkels.

The set was designated Type 268 (not to be confused with the SCR-268 from the U.S. Signal Corps), and was particularly designed to detect a submarine snorkel.

Technology and engineering have also provided Germanisms, as in the English bremsstrahlung (a form of electromagnetic radiation), or the French schnorchel (literally, "submarine snorkel," a type of air-intake device for submarine engines).
