DARPA moves forward with two companies on second-phase project for secure radio communications technologies.

The article focuses on recent advancements and contracts in military and aerospace sensor and communication technologies. Princeton Infrared is developing cost-effective shortwave infrared (SWIR) hyperspectral imagers with enhanced detection capabilities from 900 to 2500 nanometers. General Dynamics received a $481.6 million contract to maintain and upgrade the AN/MLQ-44 Prophet-Enhanced signals intelligence (SIGINT) vetronics system, which provides near-real-time electronic warfare and battlefield situational awareness. The Defense Advanced Research Projects Agency (DARPA) awarded contracts to Peraton Labs and CACI Inc. for the Wideband Secure and Protected Emitter and Receiver (WiSPER) project, aiming to develop advanced secure radio frequency (RF) communication technologies resilient to detection and interference. Additionally, the U.S. Navy contracted Lockheed Martin to supply critical components for the Infrared Search and Track (IRST) Block II system on F/A-18 Super Hornet jets, enhancing passive detection and targeting capabilities without radar use.
