AN/SPN-41A
The Telephonics ESD AN/SPN-41A is an all-weather, ship-based, radio frequency landing guidance system that provides accurate azimuth and elevation data to aircraft as they approach the ship for a landing.

For over twenty-five years, Telephonics' landing systems have been an integral part of, and have played a critical role in, ensuring the safety of carrier based aircraft. To date, over 25 systems have been delivered to the U.S. Navy and deployed on the CV, CVN, LHA, and LHD class ships with an outstanding record of performance. The AN/SPN-41A uses advanced microwave scanning beam technology providing very large guidance windows for incoming aircraft. This technology is also used to land NASA's Space Shuttles and is at the core of Telephonics' ground-based landing guidance systems for aircraft equipped with tactical instrument landing system receivers.
