What is a chaff in military terms?
Chaff is a radiofrequency countermeasure released by military aircraft, ships, and vehicles to confuse enemy radar. Chaff consists of aluminum-coated glass fibers ranging in lengths from 0.8 to 0.75 cm and is released in packets of 0.5 to 100 million fibers.
What does the chaff countermeasure do?
…of active decoy known as chaff, which consists of tiny strips of aluminum or zinc that the aircraft releases in large bunches. These metallic clouds appear as separate targets to the missile’s radar and ideally confuse the missile, thus permitting the aircraft to escape.

Joan Elizabeth Curran (26 February 1916 – 10 February 1999) was a Welsh physicist who played important roles in the development of radar and the atomic bomb during the Second World War. She invented chaff, a radar countermeasure technique credited with reducing losses among Allied bomber crews.
Did the Navy ever use Hedy Lamarr’s invention?
The Navy actually did put the system to use, but not in WW-II. Sylvania engineers reinvented it in 1957. The Navy first used frequency-hopping during the 1962 blockade of Cuba. That was three years after the Lamarr/Antheil patent had expired.
