Raytheon Missile Systems, Tucson, Arizona, is awarded $18,687,676 for cost-plus-incentive-fee delivery order N0001919F2902 against a previously awarded indefinite-delivery/indefinite-quantity contract (N00019-18-D-0123) providing the fabrication and delivery of 120 Navigation and Communication Advanced Communications Architecture Antenna Kits for the Tomahawk Block IV All-Up-Round recertification in support of the Navy.  Work will be performed in Boulder, Colorado (96 percent); and Tucson, Arizona (4 percent), and is expected to be completed in September 2020. Fiscal year 2019 weapons procurement (Navy) funds in the amount of $18,687,676 will be obligated at time of award, none of which will expire at the end of the current fiscal year.

The U.S. Air Force’s newest secure satellite communications terminal draws from existing U.S. Army and Navy systems already in operation. The new production for the Family of Advanced Beyond-Line-of-Sight Terminals, or FAB-T, evolved from technologies established in the Army’s Secure Mobile Antijam Reliable Tactical Terminal (SMART-T) and the Navy’s Multiband Terminal (NMT).

The symposium, “Novel Methods for Information Sharing in Large-scale Mobile Ad Hoc Networks,” will be held Aug. 7-8, at the conference center in DARPA’s new headquarters in Arlington, Virginia.


Scientists at the U.S. Defense Department’s top research and development agency are seeking the best new ideas to provide a larger-scale mobile network to support an increasing array of bandwidth-hungry mobile computing devices for warfighters.

The Defense Advanced Research Projects Agency (DARPA) has issued a Request for Information (RFI) for new technical approaches that would expand the number and capacity of Mobile Ad Hoc Networks (MANETs) nodes available in the field.

A U.S. Coast Guard helicopter delivers passengers from the sailing ship Bounty after the ship foundered during superstorm Sandy last October.

The synergy between operational planning and radar sensing provides enhanced search and rescue capabilities.

The U.S. Coast Guard is combining high-frequency coastal radar data with traditional oceanographic and geographic information to improve its chances of rescuing people in distress on the high seas. By merging these different sources of data, the Coast Guard enhances its search abilities while also providing better weather prediction for both its search and rescue teams and an endangered public in coastal areas.

The U.S. Army is striving to develop a multifunction electronic warfare, or MFEW, system that will provide a defensive electronic attack capability.

Melding the disciplines of spectrum combat will enable greater flexibility and more capabilities.

The growth in battlefield electronics has spurred a corresponding growth in electronic warfare. In the same manner that innovative technologies have spawned new capabilities, electronic warfare is becoming more complex as planners look to incorporate new systems into the battlespace.

Future U.S. Army vehicles may be designed to carry common components that will decrease the size, weight and power consumption of electromagnetic systems while reducing costs and improving interoperability.

An upcoming demonstration could lead to a giant leap in common electromagnetic components.

U.S. Army researchers intend to demonstrate in the coming weeks that some components, such as antennas and amplifiers, can perform two functions—communications and electronic warfare. The ultimate goal is to use the same components for multiple purposes while dramatically reducing size, weight, power consumption and costs. The effort could lead to a set of common components for electromagnetic systems across the Army, the other military services and even international partners, which would be a boon for battlefield interoperability.

NASA’s new TDRS-K communications satellite, built by Boeing, features new electronics and better power management to serve future space missions.

The TDRS constellation adds to its lifetime, but NASA planners already are looking at revolutionary technologies for the subsequent generation of orbiters.

This experimental antenna developed by LGS Innovations mimics a spherical antenna by arraying circuit boards bearing printed structures. Without having a series of electrical connections, the boards nonetheless resonate as if the construct was a spherical antenna.

Scientists bend, not break, the laws of physics.

Faced with limitations imposed by physics, laboratory researchers are generating antenna innovations by tweaking constructs to change the rules of the antenna game. Their efforts do not seek to violate long-held mathematical theorems or laws of physics. Instead, they are working to find lawful ways of working around limitations that long have inhibited the development of antennas that would suit user needs with fewer tradeoffs.

Academic investigations are establishing the future
 of transmission technology for troops and civilians.

Improving antennas for defense or commercial purposes has as much to do with mathematics as it does with hardware. Researchers in the Wireless Networking and Communications Group at the University of Texas at Austin are exploring algorithms along with other properties that should improve communications systems on the battlefield.

The Argos multiple-antenna array prototype combines 64 standard cellphone antennas into one base station that can send data directly to 16 different devices at the same time.

Beamforming could help increase capacity of cellphone networks 
to meet the demands of data-hungry smartphones and tablets.

Multi-antenna technology that could increase data capacity and maximize existing spectrum use for cellular network providers is in the early stages of development. Although widespread use of this technology will require new devices and possible network changes, the concept has shown the potential to ease mobile device congestion from smartphones and tablets. This research is underway at a time when wireless carriers worldwide are scrambling to keep up with demand for mobile data and, in some cases, are attempting to obtain additional electromagnetic spectrum.

Three 100-foot towers at Wright-Patterson Air Force Base, Ohio, provide the Air Force Research Laboratory Sensors Directorate with new capabilities to perform radar research. The actual radars atop each tower were relocated from Rome, N.Y., as part of the 2005 Base Realignment and Closure.

There is no Moore’s Law for antennas because size reduction and performance improvement will always be subject to the limitations imposed by electromagnetic physics and material properties. But steady advances in computer technologies, such as electromagnetic modeling and simulation and 3-D printing, enable antenna technology researchers to push the limits of possibility on behalf of the warfighters.

Future armored vehicles could include antennas integrated into the armor coating and other technologies designed to rid the service of whip antennas.

U.S. Army officials

 seek to replace the

 commonly used 

For decades, the U.S. Army has relied on the ubiquitous whip antenna for an array of air and ground communications, but those antennas often interfere with one another and are plainly visible to enemy soldiers in search of a target. Now, service researchers are using a wide range of technologies that could begin replacing the pervasive whip, providing more efficient, effective and reliable combat communications. Options include antennas embedded with vehicle armor, transparent antennas integrated into windshields and smart antenna technology capable of determining the optimal direction to focus transmission power.

Combining gallium and indium, Dr. Michael Dickey, assistant professor of chemical and biomolecular engineering at NC State, has created a material that he is testing for an antenna that self-heals when cut. The antenna retains its conductivity through the cut because the wire is a liquid.
