Joint precision approach and landing system

It is used on terrestrial airfields as well as the US Navy's amphibious assault ships and aircraft carriers (hull classifications LH and CVN, respectively).

First, the military needs an all-service, highly mobile all-weather precision approach system, tailorable to a wide range of environments, from shipboard use to rapid installation at makeshift airfields.

Second, they need a robust system that can maintain a high level of reliability in combat operations, particularly in its ability to effectively resist jamming.

The existing system, tactical air navigation (TACAN), is not encrypted or concealed in any way, which can reveal the location of the ship on which it is installed.

The increase in both accuracy and reliability will significantly enhance operations while reducing non-operational periods due to weather or adversarial efforts.
