Joby Aviation says a converted Cessna Caravan fitted with its autonomy system has completed the first fully autonomous flight across the United States, covering 3,199 miles from Concord, California to North Carolina's Outer Banks. The aircraft taxied, took off, navigated and landed itself at every stop, while the onboard safety pilot made zero control inputs.

The M777A2 combines a lightweight design, 155mm firepower and digital precision. Here’s how this highly mobile U.S. howitzer delivers artillery strikes while staying ready to move.

USS North Dakota spent 40 months undergoing maintenance. Its overhaul highlights the challenges facing America’s submarine fleet — and the massive operational costs of maintenance delays.

The Gray Eagle carries Hellfires & a multi-spectral targeting system, loitering for up to 25 hours while feeding real-time intel to ground commanders. Its seamless ISR-to-strike transition without returning to base makes it one of the Army's most flexible armed drones.

The Aster 15 uses PIF-PAF thrust-vectoring to pull terminal maneuvers no conventional missile can match — engaging sea-skimmers at 30km from SYLVER VLS cells. It provides the inner layer of a naval air defense architecture built for saturation attacks.

The HAROP autonomously hunts radar emissions, loiters for up to six hours, then dives its 23kg warhead directly into the emitter — no separate warhead needed. If no target is found, it can be recalled and recovered, making it as economical as it is lethal.

The Gripen C/D added NATO datalink, in-flight refueling & an expanded weapons suite including IRIS-T, AMRAAM & Taurus KEPD 350. Its 10-minute turnaround & highway strip capability give smaller air forces a sortie rate far more expensive platforms can't match.

The Gvozdika crosses rivers under its own power, keeping indirect fire support pace during amphibious ops. Its 122mm howitzer reaches 15km — decades after introduction, still active across Eastern Europe, the Middle East & Africa.

Researchers at the University of Colorado Boulder have developed ORCA — the Open Radar Code Architecture — a free, open-source software framework that turns commercially available software-defined radios into functioning radar systems for environmental science, without requiring users to have a radar engineering background. The problem ORCA solves is a well-known frustration in radar research: every new student joining a lab typically spends up to a year rebuilding the same basic control code from scratch before any actual science can begin. "Every new student is just recreating the wheel over and over," said assistant professor Nicole Bienert. With ORCA, researchers buy a software-defined radio — now available for a few thousand dollars compared to hundreds of thousands for traditional radar systems — attach off-the-shelf antennas and cables, download the code, and have a functioning radar. Current applications include measuring glacier ice thickness in the Arctic, determining water content within trees, and studying ice sheet base conditions. The platform has grown through monthly meetings and online forums with participants from multiple universities across continents, and researchers can contribute their own code via GitHub. The initiative aims to make radar accessible to geophysicists, ecologists, and other scientists who have environmental questions but lack the technical background to build radar systems from scratch.

LeVanta Tech, a defence startup based in Diamondhead, Mississippi, is building HALIA, an uncrewed aircraft that floats motors-off on the open sea, then lifts itself onto three hydrofoils, skates across the surface and takes off without a runway or a catapult. The company says its prototype has demonstrated float, take-off, flight and water landing, with the float-to-airborne transition done in under 60 seconds, while figures such as 30 days on station and 120 nautical miles of range remain modelled targets. It is funded by US Air Force and Navy SBIR Phase II contracts and is covered by a memorandum of understanding signed with Ukraine's defence industry in October 2025.
