Navy Considering Multi-Aperture Antennas to Improve Electronic Warfare (EW) Operations Aboard Surface Warfare Ships

SAN DIEGO- U.S. Navy Electronic Warfare (EW) experts survey the industry to find companies capable of performing communications, electronic support and electronic attack from the same antenna array aboard naval vessels naval surface.

Officials at the Naval Information Warfare Center-Pacific in San Diego issued a Request for Information (NIWC_Pacific_MKTSVY_1754EE) on Tuesday for the Active Electronically Steered Array (AESA) and Phased Array Fed Reflector (PAFR) project.

Navy experts want to identify companies that can determine if electronically active array (AESA) and phased array fed reflector antennas can provide high broadband UHF to SHF transmit and receive capability at radiated power very high effective isotropic and gain as a function of temperature.

These capabilities should be small in size, weight, power consumption, cooling, and cost. The transmit and receive opening must not exceed 73 inches high, 73 inches in diameter, have a deck-mounted support pedestal no greater than 24 inches, and weigh no more than 1,000 pounds.

Navy experts say they need the ability to conduct communications, electronic support and electronic attack operations aboard surface warships from a small opening to deal with current threats and future. This is achieved by a high broadband effective isotropically radiated power transmit and receive network in at least the S-X band, and a lower effective isotropically radiated power transmit and receive capability in the bands L to Ku are required.

Given the limitations of available space on board ships, the Navy wishes to make electronic support and electronic attack functions available from the same opening.

Each proposed solution must be a modular design that can be configured for several different missions and use technology mature enough to be validated in a simulated environment (TRL-6).

Interested companies should email white papers no later than February 5, 2021 to Scott Henrikson of the Navy at scott.a.henriksonatnavy.mil. Email your questions or concerns to Scott Henrikson at scott.a.henriksonatnavy.mil.
